(Educational Piano Library). Scales, Patterns and Improvs provides students with a valuable resource for building technique through one octave scales, I-IV-V7 chords and arpeggios in all major and minor keys. Students apply these basic skills through improv exercises and reading pieces in every key, and by learning to transpose, create an accompaniment and play from a lead line. The accompanying audio features MIDI orchestrations for all improvs and exercises. Plus, the files include playback tools to assist with slowing down the tempo for practicing.
