@@moeb4348 thanks for asking! I’m thinking the key of G major. The note is a passing tone between 5 & 6. So I suppose you could call it a minor 6th from the root. That Same note over the five chord is a flat nine between the root and 9 of that V chord. The more common “bebop note” over the V is a passing tone between its root and flat 7. In the tonal center/key of G, it would be a #4 (or flat 5, if you prefer). Not sure the interval label is as useful as the way it sits as a passing tone in the line construction. This video explains the concept (I hope). ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3EkSqwWuBxg.htmlsi=SsPcj27Pj8ozOOlx
@@ScottM65 Thanks. That's what I gathered after watching a few times and playing along. It's a very cool note and works well with the B-bop progression. When I play it, it makes me sound like I really know how to solo in jazz! Even though, I am just a beginner. Great post.
