Is this the process you follow to form your 11ths when you are playing?
Do you mind the thought process you follow when you want to play 11ths in songs..
I just think of them as 4ths with 7ths in them..I play the 3rds most of the time, so all I really have to concern myself about are the 7ths of the chord I intend to play next..the 4th is not that much of an issue because I know it's either a whole step above the 3rd (minor) or just a half step (major).
That's how I think of it before I hit the chord..so what I do think about more is the voicing of the chord..but that is primarily determined by the melody note for me..
I hope all this makes sense.
