Peterson’s left hand is incredibly active—walking tenths, stride patterns, and chord voicings with inner movement. Don’t try to play it at tempo right away. Isolate left-hand patterns and practice them slowly with a metronome.
Peterson's harmonic approach on "Days of Wine and Roses" is characterized by a rich, impressionistic use of chordal voicings and extensions. Throughout the solo, he frequently adds 7th, 9th, and 11th chords to the basic progression, often using block chords and Rootless voicings to create a greater sense of harmonic density. oscar peterson days of wine and roses transcription
