@haltber: In this video, I demonstrate a very useful method to master 2-5-1 progressions in all 12 major keys, always using full ninth chords. The choice of keys for enharmonic equivalents (like Gb instead of F#) was mostly arbitrary. This is a concise version of the full tutorial (landscape format), which includes step-by-step chord construction explanations and is available on my YouTube channel. #chordprogression #pianotutorial #jazzharmony #pianoplayer #musictheory #haltber
