First, the concept of modes is discussed in detail, as well as modal harmony and composition. Their use in conventional jazz tunes as well as modal ones is explored. Next, chord scales and their application over specific chords, left hand voicings for blues, blues progression variations, and pentatonic scales are covered in detail. The chapter on pentatonics also includes inversions or positions for pentatonics, their application over specific chords, and even the use of altered pentatonics. The book then covers more advanced theory including minor harmony, dominant chord substitution, upper structure triads, voicings in fourths, diminished chord patterns and substitutes, and modulations. Numerous exercises and examples are included and performed on the accompanying CD. Excellent for the individual jazz student or classroom study, this book is applicable for all instruments.
