Jazz Chord Voicings: minor 7 chords

Minor 7 chords can be notated as Cm7, Cmin7, or C-7.

Method 1:
I love this voicing because it is so EASY!!
Play a minor chord (CEbG)
Add a minor 3 on top of it (CEbGBb)
Invert it once (EbGBbC)
Raise the Root (C) one whole step (EbGBbD). Your Root just became a 9th.
This chord SOUNDS like a Major 7 chord, but it's really called a minor 9 chord. If you can figure up a minor 3rd from your Root and build a Root position M7 chord, that gives you a very nice sounding minor 7 chord.
I have been using this voicing with C-7, Db-7, E-7, Eb-7 and D-7.

Method 2:
Play a minor chord (ACE)
Add a minor 3rd on top of it (ACEG)
Put your top note on the bottom (B Position) (GACE)
Raise the 5th (A) a whole step (GBCE). Your 5th just became a 6th, and you have an A-13 chord, that functions nicely for an A-7.
I ave been using this voicing with A-7, G-7, Ab-7, Bb-7, B-7, and F#-7.

Method 3:
This method seems so easy that it is almost like cheating, because it more or less stays in Root Position.
Play a minor chord (FAbC)
Add the minor 3rd on top (FAbCEb)
Raise the Root (F) one whole step (GAbCEb). Now you don't have a root in your chord anymore. It just became F-9, but you can use it as F-7.
