Hi everyone,

Do you have any idea when these chords are

e
b
g 9
d 9
a x
E 9

e 2
b 2
g 2
d 2
a
E

e 2
b 0
g 2
d 2
a
E
#2
c# minor 7th, A/E 6th, and A/E 6th sus 2

Last two could be considered something else depending on the key
#4
most likely C#m7, F#m7/E, and F#m11/E. depends on context and if nothing is really changing between the last two chords i'd just call them both F#m7 and consider the B a color tone.
Anfangen ist leicht, Beharren eine Kunst.
