Here is an option that can be used over certain ii-V-I progressions.
We will concentrate on the V7 chord for our alteration here.
Example in Eb Major:
Step one:
Play minor chord: F-
(or ignore this chord and jump right to step 2)
Step two:
Take the Root, 3rd, and 7th. (Bb, D, Ab)
Stack on top of that a triad built from the 6. (G, B, D)
Stack within the same octave a triad built off of the b6. (Gb, Bb, Db)
we get some nice extensions by doing this. (b9, b13, and #9.)
Step three:
Resolve to the Major chord (Eb).
