An immensely important series of books, each one on a different instrument or group of instruments within the 'orchestral' family. Yehudi Menuhin was the general editor of the series originally launched in the 1970s. Every contribution is by an acknowledged master of his chosen instrument. The series is aimed at music students of all ages, amateur musicians, music teachers and all readers actively committed to music. It is the unique merit of the series that each book represents the individual view of its author (within an accepted framework) and, since each contributor is a musician of outstanding talent as well as an expert in his or her particular field, this approach gives the music guides their character and validity.
