A fundamental jazz improvisation skill is the ability to hear, think, see, and play the chord tones in the i chord in any minor key…
Minor Triad Arpeggio…
You always sing out loud using Solfege to train your ears, right?
Next Chord Tone Up & Down…
You always play with a rhythm track and play with good time, right?
Skips…
Record yourself, always–listen to the playback, and ask: “Is that what I intended to play?”
Homework
As always, study and practice the patterns above for all minor keys–using all four musical intelligences: ears, intellect (theory), eyes, and muscles!
