Advanced Contemporary Chordal Sequences for Clarinet - 276 Technical Studies by Kalmen Opperman. Carl Fischer, 1999, SS, 96 pages. Contemporary composers are writing more technical, exotic lines for the clarinet, often because of the various register color changes and the instrument's convenient extended range. The exercises in this book are intended to support and extend the technical expertise of students and professionals required to perform this modern music. The chords are shown before the exercises but not identified. (Note: In late 2010 the title of this book was revised with the addition of the word "Advanced.") There is also an Intermediate Level book. (C0108)
