hey i got a few questions about chords. I just got a new jazz chart and theres no notation, just says the chord names and has slashes and says "walk" Ok so if it doesn't say major or minor does that mean its major by default? I notice the chart says F7 and Eb7 alot but doesn't say if its major or minor? I notice the chart says Bb7 MI several times and Bb7 MA once. Is it just being nice to remind me that its MA instead of MI that one time? Kind of like how some charts will remind you of a key sig after an accidental but others wont? also what does it mean if it says 9? does that mean root 3rd 5th 7th and a 9th? is a 9th a semitone above the octave? or is it the second note in the scale above the octave? also it says F7 sus(#9) what does the sus mean and the 9 in brackets mean? thanks for all your help guys I really appreciate it!
