The 300th anniversary of Henry Purcell's death in 1995 stimulated a good deal of new research into his music, its sources, performance, reception and cultural context. The 23 articles in this volume have been chosen by Peter Holman as a representative selection of the best scholarly writing over the last few decades, featuring most of the leading Purcell scholars, including Curtis Price, Robert Thompson, Robert Shay, Bruce Wood, Rebecca Herissone, and Christopher Hogwood, though it also includes some earlier classic articles, by Michael Tilmouth, Richard Luckett, Margaret Laurie and others. The four sections are 'Biography and Contexts', 'Sources, Editing and Publishing', 'Styles, Genres and Compositional Process', and 'Performance, Performance Practice and Reception'. Peter Holman's introduction explores the history of Purcell scholarship, reviews its present state, comments on the significance of the articles, and offers a prospect for the future.

Claudio Monteverdi is now recognized as the towering figure of a critical transitional moment of Western music history: relentless innovator in every genre within chamber, church and theatre music; self-proclaimed leader of a 'new dispensation' between words and their musical expression; perhaps even 'Creator of Modern Music'. During recent years, as his arrestingly attractive music has been brought back to life in performance, so too have some of the most outstanding musicologists focussed intensely on Monteverdi as they worked through the 'big' questions in the historiography and hermeneutics of early Baroque music, including musical representation of language; compositional theory; social, institutional, cultural and gender history; performance practices and more. The 17 articles in this volume have been selected by Richard Wistreich to exemplify the best scholarship in English and because each, in retrospect, turns out to have been a ground-breaking contribution to one or more significant strands in Monteverdi studies.

Orchestral Repertoire: An Annotated Guide for Non-Professional Orchestras is a repertoire and programming resource for any conductor who leads a non-professional symphonic orchestra. Based on the model of and intended as a compliment to David Daniels's Orchestral Music, this book offers practical and insightful commentary on repertoire appropriate for intermediate and advanced youth, community, and collegiate orchestras. Functioning like an annotated bibliography, Orchestral Repertoire: An Annotated Guide for Non-Professional Orchestras contains entries on individual symphonic works including information about the composer, instrumentation, movement length, and publisher. Additionally, each entry features notes regarding the particular pedagogical, stylistic, logistical, and technical strengths and challenges of the specific work. There are many considerations specific to non-professional ensembles that are essential to selecting repertoire that is appropriate and successful. For instance: Non-professional and student ensembles may not have access to the full spectrum of auxiliary instruments as a professional ensemble, or have players who have experience with them. It can be very beneficial to know in advance if there are any particularly challenging exposed solos in a work. This book can guide repertoire selections for a non-professional ensembles where there is often pressure to make sure everyone is playing as much of the time as possible. Non-professional ensembles often have to manage the reality that sections are at different levels of experience and maturity. Educational conductors focus not only on programming a season that will please audiences, but also consider how to provide stylistic variety to our own players and teach specific ensemble skills through the selection of repertoire. Orchestral Repertoire: An Annotated Guide for Non-Professional Orchestras can help every conductor in the process of selecting repertoire that will both feature and enrich any individual non-professional ensemble for which thoughtful and strategic programming is required.

The prominent symphony conductor Maurice Peress describes his career, conducting the premier of such works as Leonard Bernstein's Mass and Duke Ellington's Queenie Pie and recreating the premier of the concert featuring George Gershwin's Rhapsody in Blue and Ellington's Black, Brown and Beige. He also traces the great impact that African-American music has had upon American music, from the influence of compser Antonin Dvorak through the 1920s.

Franz Schubert (1797-1828) is now rightly recognized as one of the greatest and most original composers of the nineteenth century. His keen understanding of poetry and his uncanny ability to translate his profound understanding of human nature into remarkably balanced compositions marks him out from other contemporaries in the field of song. Schubert was one of the first major composers to devote so much time to song and his awareness that this genre was not rated highly in the musical hierarchy did not deter him, throughout a short but resolute and hard-working career, from producing songs that invariably arrest attention and frequently strike a deeply poetic note. Schubert did not emerge as a composer until after his death, but during his short lifetime his genius flowered prolifically and diversely. His reputation was first established among the aristocracy who took the art music of Vienna into their homes, which became places of refuge from the musical mediocrity of popular performance. More than any other composer, Schubert steadily graced Viennese musical life with his songs, piano music and chamber compositions. Throughout his career he experimented constantly with technique and in his final years began experiments with form. The resultant fascinating works were never performed in his lifetime, and only in recent years have the nature of his experiments found scholarly favor. In The Unknown Schubert contributors explore Schubert's radical modernity from a number of perspectives by examining both popular and neglected works. Chapters by renowned scholars describe the historical context of his work, its relation to the dominant artistic discourses of the early nineteenth century, and Schubert's role in the paradigmatic shift to a new perception of song. This valuable book seeks to bring Franz Schubert to life, exploring his early years as a composer of opera, his later years of ill-health when he composed in the shadow of death, and his efforts to reflect in his music his own profound inner experience.

Intended as a supplement to The Mechanical Muse: The Piano, Pianism and Piano Music, c.1760-1850, this Companion provides additional information which, largely for reasons of space but also of continuity, it was not possible or desirable to include in that volume. The book is laid out alphabetically and full biographical entries are provided for all musical figures mentioned, including composers, performers, theoreticians and teachers, as well as piano makers and publishers of music, within the period covered by The Mechanical Muse. There are also entries on figures of importance from outside the period but whose influence is palpably important within it, such as J.S. Bach. As well as biographical information, all these entries contain lists of principal works and a section on further reading so that readers can follow up people and matters of particular interest. Also included in The Companion are entries devoted to particular works and other information of relevance, such as descriptions of musical forms, characteristics of dances and so on, as well as some technical information on music and explanations of technical terms pertaining to keyboard instruments themselves and to ways of playing them. This Companion is not intended to replace existing reference books such as Grove or Musik in Geschichte und Gegenwart, but will be useful for those who desire to know more about a particular topic and do not necessarily have access to more specialist reference works, or time to visit large or specialist libraries. As such it is indispensable to users of The Mechanical Muse.

This book charts the piano's accession from musical curiosity to cultural icon, examining the instrument itself in its various guises as well as the music written for it. Both the piano and piano music were very much the product of the intellectual, cultural and social environments of the period and both were subject to many influences, directly and indirectly. These included character (individualism), the vernacular ('folk/popular') and creativity (improvisation), all of which are discussed generally and with respect to the music itself. Derek Carew surveys the most important pianistic genres of the period (variations, rondos, and so on), showing how these changed from their received forms into vehicles of Romantic expressiveness. The piano is also looked at in its role as an accompanying instrument. The Mechanical Muse will be of interest to anyone who loves the piano or the period, from the non-specialist to the music postgraduate.

From acclaimed composer and biographer Jan Swafford comes the definitive biography of one of the most lauded musical geniuses in history, Wolfgang Amadeus Mozart. From his earliest years it was apparent that the singular imagination of Wolfgang Mozart was tirelessly at work. He hated to be bored and hated to be idle, and he responded to these threats with a repertoire of antidotes mental and physical, going at every part of his life with tremendous gusto. His circle of friends and patrons was wide, encompassing anyone who appealed to his boundless appetites for music and all things pleasurable and fun. As a man, Mozart was an inexplicable force of nature who could rise from a luminous improvisation at the keyboard to meow like a cat and leap over the furniture. He was forever drumming on things, tapping his feet, seeming both present and apart. But he also might grasp your hand and gaze at you with a profound, searching and melancholy look in his blue eyes. It was as if Mozart lived onstage and off simultaneously, a character in life's tragicomedy but also outside of it, watching, studying, gathering material for the fabric of his art. Like Swafford's biographies Beethoven, Johannes Brahms and Charles Ives, Mozart is both wide-ranging and intimate in its exploration of a genius in his life and his setting: a man who rose from a particular time and place, whose art would enrich the world for centuries to come, who would immeasurably shape the future of classical music, who from his age to ours has stood as the definition of a prodigy. As Swafford reveals, to understand the evolution of music it is vital to understand this singular genius as a man and an artist.

Examines the remarkable career of leading soprano castrato Venanzio Rauzzini (1746-1810), the first castrato to make Britain his home. Venanzio Rauzzini (1746-1810), the celebrated Italian castrato, is best known for his performance in Mozart's Lucio Silla in 1772, with which Mozart was so pleased that he composed for the singer the famous motet Exsultate Jubilate. In 1774, Rauzzini moved to London where he performed three seasons of serious operas at the King's Theatre. From 1777 until his death in 1810, he was the director of the concert series in Bath, a series that matched the prestige of any that were given in London. In addition, he composed prolifically, writing music for eleven operas. This book is a study of Rauzzini's remarkable yet often overlooked career in Britain. Paul Rice chronicles Rauzzini's performances at the King's Theatre and examines his leadership of the Bath subscription concerts from 1780-1810, recovering much of the repertory. Rice shows in detail how Rauzzini responded musically to the social and political conditions of his adopted country, and analyzes the castrato's reception, as well as compositional choices, shedding new light on changing musical tastes in late eighteenth-century Britain. Paul F. Rice is Professor of Musicology at the School of Music, Memorial University of Newfoundland.

Whilst E.T.A. Hoffmann (1776-1822) is most widely known as the author of fantastic tales, he was also prolific as a music critic, productive as a composer, and active as a conductor. This book examines Hoffmann's aesthetic thought within the broader context of the history of ideas of the late-eighteenth and early-nineteenth centuries, and explores the relationship between his musical aesthetics and compositional practice. The first three chapters consider his ideas about creativity and aesthetic appreciation in relation to the thought of other German romantic theorists, discussing the central tenets of his musical aesthetic - the idea of a 'religion of art', of the composer as a 'genius', and the listener as a 'passive genius'. In particular the relationship between the multifaceted thought of Hoffmann and Friedrich Schleiermacher is explored, providing some insight into the way in which diverse intellectual traditions converged in early-nineteenth-century Germany. In the second half of the book, Hoffmann's dialectical view of music history and his conception of romantic opera are discussed in relation to his activities as a composer, with reference to his instrumental music and his two mature, large-scale operas, Aurora and Undine. The author also addresses broader issues pertaining to the ideological and historical significance of Hoffmann's musical and literary oeuvre.

The Italian violinist and composer Giovanni Battista Viotti (1755-1824) is considered today to have been one of the most significant forces in the history of violin playing. In 1792 he met Margaret and William Chinnery, a wealthy English couple with strong connections in the world of arts and letters. From that point onwards Viotti's life became inextricably bound up with theirs; he moved into their home and became a second father to their children, forming a remarkably successful menage A trois. Henceforth, all Viotti's career decisions were taken with this family's welfare in mind. The Chinnery Family Papers feature over 100 Viotti letters and other documents. Drawing extensively on these papers, this book investigates the new light that they cast on Viotti's life and career, as well as the context in which he lived and worked. Fresh insights are given into the reception of Viotti's concertos in London and the solo performances he gave while in England, together with new information on his role as a music teacher in the Chinnery household, and his relationship with Mme de StaA"l and the Philharmonic Society.

Haydn is enjoying renewed appreciation as one of the towering figures of Western music history. This lively collection builds upon this resurgence of interest, with chapters exploring the nature of Haydn's invention and the cultural forces that he both absorbed and helped to shape and express. The volume addresses Haydn's celebrated instrumental pieces, the epoch-making Creation and many lesser-known but superb vocal works including the Masses, the English canzonettas and Scottish songs and the operas L'isola disabitata and L'anima del filosofo. Topics range from Haydn's rondo forms to his violin fingerings, from his interpretation of the Credo to his reading of Ovid's Metamorphoses, from his involvement with national music to his influence on the emerging concept of the musical work. Haydn emerges as an engaged artist in every sense of the term, as remarkable for his critical response to the world around him as for his innovations in musical composition.

Johann Peter Salomon, the celebrated violinist and impresario, made his debut in England in March 1781. History has credited Salomon with bringing Haydn to London, yet as Ian Woodfield reveals in this monograph, Salomon's introduction of the composer to the London musical scene owed as much to luck as to skilful planning. Haydn's engagement in London proved to be a much-needed uplift to Salomon's career which, as Woodfield illustrates, had been on the wane for a number of years. In addition to its reassessment of Salomon's uneven career in London during the 1780s, this book throws light on the general relationship between public and private spheres of professional music-making at the time, and on the relationship between the social and professional attributes required of musicians if they were to be successful. Nowhere are these tensions better illustrated than in the letters and journals of the Burney family, especially those of Susan Burney, which are drawn on in the book to provide a vivid picture of the fiercely competitive musical world of eighteenth-century London.

Beethoven's orchestral works include some of the most iconic and popular pieces of classical music ever written. In this book, author and music critic David Hurwitz surveys all of his symphonies, overtures, concertos, theatrical music, his single ballet and other music for the dance, and several short pieces worth getting to know. It offers chapters on Beethoven's handling of the symphony orchestra and his contributions to its evolution, as well as his approach to musical form in creating large, multi-movement works. The musical descriptions provide helpful strategies for listening that invite both beginners and experienced enthusiasts to treat even the best known pieces as something fresh, new and relevant. In addition, Hurwitz provides extensive lists of recommended recordings of all of the music surveyed, highlighting the wide range of issues in Beethoven interpretation and performance, as well as the history of his music on disc. He encourages readers to listen actively and critically, as they build their own Beethoven discographies according to their personal tastes and preferences.

A fully updated edition of the leading reference work on musical key characteristics during the Baroque, Classical and Romantic periods. This is a revised second edition of Dr. Steblin's important work on key characteristics, first published in 1983 by UMI Research Press and re-issued by the University of Rochester Press in 1996. The revision has been limited to athorough correction and update of the material in the first edition, so as to not disrupt the content and organization, for which the book has been praised as a significant and noteworthy reference for both scholars and research students alike. The book discusses the extra-musical meanings associated with various musical keys by ancient Greek and medieval-renaissance theorists and in particular composers and writers on music in the Baroque, Classical,and early Romantic periods. Chapters focus on Mattheson's extensive key descriptions from 1713, the Rameau-Rousseau and Marpurg-Kirnberger controversies regarding unequal versus equal temperaments, and C.F.D. Schubart's influential list based on the sharp-flat [bright-dark] principle of key-distinctions. Rita Katherine Steblin is a world-renowned music scholar, living and working in Vienna.

In the nineteenth century, copyright law expanded to include performances of theatrical and musical works. These laws transformed how people made and consumed performances. Exploring precedent-setting litigation on both sides of the Atlantic, this book traces how courts developed definitions of theater and music to suit new performance rights laws. From Gilbert and Sullivan battling to protect The Mikado to Augustin Daly petitioning to control his spectacular 'railroad scene', artists worked with courts to refine vague legal language into clear, functional theories of drama, music, and performance. Through cases that ensnared figures including Lord Byron, Laura Keene, and Dion Boucicault, this book discovers how the law theorized central aspects of performance including embodiment, affect, audience response, and the relationship between scripts and performances. This history reveals how the advent of performance rights reshaped how we value performance both as an artistic medium and as property.

The second half of the eighteenth century witnessed a flourishing of the string quartet, often represented as a smooth and logical progression from first violin-dominated homophony to a more equal conversation between the four voices. Yet this progression was neither as smooth nor as linear as previously thought, as Mara Parker illustrates in her examination of the string quartet during this period. Looking at a wide variety of string quartets by composers such as Pleyel, Distler and Filtz, in addition to Haydn and Mozart, the book proposes a new way of describing the relationships between the four instruments in different works. Broadly speaking, these relationships follow one of four patterns: the 'lecture', the 'polite conversation', the 'debate', and the 'conversation'. In focusing on these musical discourses, it becomes apparent that each work is the product of its composer's stylistic choices, location, intended performers and intended audience. Instead of evolving in a strict and universal sequence, the string quartet in the latter half of the eighteenth century was a complex genre with composers mixing and matching musical discourses as circumstances and their own creative impulses required.

Practical suggestions, and documentary evidence, for performers wishing to understand the gestures and nuances embedded in eighteenth-century musical notation. There are, of course, no commas, periods, or question marks in music of the Baroque and Classic eras. Nonetheless, the concept of "punctuating" music into longer and shorter units of expression was richly explored by many of the era's leading composers, theorists, and performers. The Art of Musical Phrasing in the Eighteenth Century gathers and discusses, for the first time, an extensive collection of quotations and musical illustrations relevant tophrase articulation and written and unwritten rests. Among the notable authors cited and discussed are Muffat, Telemann, C. P. E. Bach, Mattheson, Marpurg, Tartini, and Mozart's father Leopold (author of the most important eighteenth-century treatise on string playing). On a larger scale, The Art of Musical Phrasing demonstrates the role of punctuation within the history of rhetoric during the Age of Enlightenment. From this, the performer of todaycan gain a greater appreciation for both the strengths and shortcomings of the analogy that writers of the day drew between punctuation in written language and in music. Modern performers, argues Vial, have the challenge andresponsibility of understanding and conveying the nuances, inflections, and rhythmic gestures deeply embedded in eighteenth-century musical notation. The Art of Musical Phrasing, the fruit of Vial's rich experience as a cellist performing on both period and modern instruments, lays out long-needed practical suggestions for achieving this goal. Stephanie D. Vial performs and records widely as a cellist and has taught at the University ofNorth Carolina at Chapel Hill and Duke University.

Casts new and valuable light on English musical history and on Enlightenment culture more generally. This is a book guaranteed to make waves. It skilfully weaves the story of one key musical figure into the story of one key institution, which it then weaves into the general story of music in eighteenth-century England. Anyone reading it will come away with fresh knowledge and perceptions - plus a great urge to hear Cooke's music.' Michael Talbot, Emeritus Professor of Music at the University of Liverpool and Fellow of the British Academy. Amidst the cosmopolitan, fashion obsessed concert life of later eighteenth century London there existed a discrete musical counterculture centred round a club known as the Academy of Ancient Music. Now largely forgotten, this enlightened school of musical thinkers sought to further music by proffering an alternative vision based on a high minded intellectual curiosity. Perceiving only ear-tickling ostentation in the showy styles that delighted London audiences, they aspired to raise the status of music as an art of profound expression, informed by its past and founded on universal harmonic principles. Central to this group of musical thinkers was the modest yet highly accomplished musician-scholar Benjamin Cooke, who both embodied and reflected this counterculture. As organist of Westminster Abbey and conductor of the Academy of Ancient Music for much of the second half of the eighteenth century, Cooke enjoyed prominence in his day as a composer, organist, teacher, and theorist. This book shows how, through his creativity, historicism and theorising, Cooke was instrumental in proffering an Enlightenment-inspired reassessment of musical composition and thinking at the Academy. The picture portrayed counters the current tendency to dismiss eighteenth-century English musicians as conservative and provincial. Casting new and valuable light on English musical history and on Enlightenment culture more generally, this book reveals how the agenda for musical advancement shared by Cooke and his Academy associates foreshadowed key developments that would mould European music of the nineteenth century and after. It includes an extensive bibliography, a detailed overview of the Cooke Collection at the Royal College of Music and a complete list of Cooke's works. TIM EGGINGTON is College Librarian at Queens'College, Cambridge.

Remarkable new study...Its central submission, that we have hitherto disregarded or misinterpreted the most profound intuitions of a unique composer, certainly carries conviction. And even after one reading there are already musical passages that this Schubert enthusiast finds himself hearing in quite a new way. Bayan Northcott, BBC MUSIC MAGAZINE A sensitive and richly allusive commentary... likely to change the way we listen to certain works. Brian Newbould The old stereotypes of Schubert as Bohemian artist and unselfconscious creator have been replaced over the past half-century with a picture of a difficult man in difficult times. The author aims to redress the balance, concentrating firstly on works where Schubert's beliefs are clearly expressed (masses, other religious music, songs amounting to Geistliche Lieder). This also prompts an examination of instrumental masterpieces (Unfinished and Great C Major Symphonies, and the Wanderer Fantasy), which show that Schubert's religious side encompasses awe and terror as well as wonder. Schubert's 'complete voice' is thus clearly heard, rather than the sombre one currently emphasised in both literature and concert. LEO BLACK is a former BBC chief producer for music.

This book contains sixteen essays on Venetian music in its last great period, stretching from the second half of the 17th century to the fall of the Republic in 1797. Two essays deal with musical institutions (academies and conservatories), nine with the life and works of Antonio Vivaldi, and five with contemporaries of Vivaldi active in Venice (Albinoni, Marcello, Vinaccesi). A substantial supplementary chapter updates, and where necessary revises, the facts and arguments of the original essays, which collectively date from the years 1973-1995. All the essays are written in English, but many originally appeared in Italian journals and conference proceedings that are hard for English-speaking readers to obtain. The volume is carefully indexed, enabling the reader easily to make connections between the essays.

A History of the Symphony: The Grand Genre identifies the underlying cultural factors that have shaped the symphony over the past three hundred years, presenting a unified view of the entire history of the genre. The text goes beyond discussions of individual composers and the stylistic evolution of the genre to address what constitutes a symphony within each historical period, describing how such works fit into the lives of composers and audiences of the time, recognizing that they do not exist in a vacuum but rather as the products of numerous external forces spurring their creation. In three parts, the text proceeds chronologically, drawing connections between musical examples across regions and eras: The Classical Symphony The Romantic Symphony The Symphony in the Modern Era Within this broad chronology-from the earliest Italian symphonies of the 18th century to the most experimental works of the 20th century-discussion of the development of the genre often breaks down along national lines that outline divergent but parallel paths of stylistic growth. In consideration of what is and is not a symphony, musical developments in other genres are presented as they relate to the symphony, genres such as the serenade, the tone poem, and the concert overture. Suitable for a one-semester course as well as a full-year syllabus, and with illustrative musical examples throughout, A History of the Symphony places composers and works in sociological and musical contexts while confronting the fundamental question: What is a symphony?

Ernest Newman's four-volume Life of Wagner, originally published between 1933 and 1947, remains a classic work of biography. The culmination of forty years' research on the composer and his works (Newman's first Study of Wagner was first published in 1899), these books present a detailed portrait of perhaps the most influential, the most controversial and the most frequently reviled composer in the whole history of western music. Newman was aware that no biography can ever claim to be complete or completely accurate: 'The biographer can at no stage hope to have reached the final truth. All he can do is to make sure that whatever statement he may make, whatever conclusion he may come to, shall be based on the whole of the evidence available at the time of writing.' In this aim he triumphantly succeeds. Volume 2 covers the years 1848 to 1860.
