While reading the Jazz Guitar Chord Mastery book by Joseph Alexander, I've encountered a passage that is not 100% clear to me. I would be very thankful if you might help.
Playing a m7b5 chord on the sixth of a minor chord creates a Minor 6 chord quality. In the above example we create a m6 sound by playing m7b5 on the sixth (D) of the original m7.
So the original m7 is F#m7 chord, am I right? Since the 6th step of F#m7 is D. I'm a little bit confused here because previously an Fm7 chord was mentioned.
Many thanks for taking your time reading this!
