Level Two is an intermediate-level course covering larger chord forms, "definitive" chords in major and minor keys, substitutions, analysis of key centers in tunes, "upper structure" chords, voiceleading, and pentatonic and blues scale applications, a complete glossary of terms, and hundreds of written theory exercises with answers. | Contemporary Music Theory - Level Two by Mark Harrison, Paperback | Indigo Chapters
