This wonderful book continues and expands the concepts in Jim Ployhar's highly successful "I Recommend" band study.  Each of the first 24 pages begins with a well-known chorale, followed by an etude focusing on various articulations, rhythmic patterns, styles or other important points of practice.  The beauty of these etudes, however, is that in addition to being presented in unison, they are also written with simple accompaniments - 4-part accompaniments for 18 of them and duet parts for the other 6.  This means that you can focus on certain sections of the band while still involving everyone.  You can turna useful exercise for a few into a rewarding musical experience for all!  These studies are carefully selected, time-honored etudes by masters such as Arban, Klose, Concone, Shanti, Pares and Saint-Jacome.  Following these etudes, there are scale studies for brasses only and woodwinds only, with the brasses playing accompaniments to the woodwind studies and vice versa.  An exceptionally valuable book!
