Wiseman Project Music Theory Series This book is intended for those who, having already gained competent knowledge of four-part harmony, desire to write with confidence in five parts. Five-part writing used to be compulsory for the degree of Bachelor of Music at major universities and conservatories. However, many institutions have dropped the subject from the requirement, although the knowledge of the subject would be a great asset for those who want to compose for larger ensembles such as symphony orchestra or large chorus or those who wish to compose with extended harmonies. The plan of this work is arranged and updated in such a manner that anyone who is already well instructed in harmony may advance without the aid of a teacher. In each chapter, a problem is proposed, and its solution is given in the Appendix 1 and 2. For students who are not familiar with Alto and Tenor Clefs, both traditional and modern notation for alto and tenor parts are included.
