Let's take a look at some interesting chord shapes that could be used for the first four bars of The Real Book version of Charlie Parker's "Blues For Alice"
F6
The next four bars of the tune starts with a Bb7 (we'll use a Bb9 to match the C in the melody), followed by a descending 2- 5 pattern. Let's see what this could look and sound like.
Bb9
Here's a few chord shapes that could be used for the final four bars of the tune. We are substituting C13 for C7, to highlight the A note in the melody. We are also substituting C7b9 for downward harmony movement in the last bar, but a C13 would work perfectly here as well to highlight the A note in the melody, the last note of the song.
