Virtual Jam Session - "Peace"

Mellow out to "Peace"

---

This is a lesser-known song by Horace Silver: "Peace".  It is a beautiful, haunting melody that is a great platform for working on your ballad chops.  But don't be fooled by what sounds like a simple composition.  This has an unconventional song form and very unconventional chord progression.
It is a 10-bar form.
The chords don't go where you might expect them to go.  Here is the chord progression (in concert key).  Please notice that there are lots of half-diminished (i.e. m7b5) chords and also many 7(b9) chords which are essentially diminished chords with an altered bass, work on those diminished intervals:

||: Am7(b5)    D7(b9             |  Gm             C7        |
    Bmaj7        Cm7(b5)  F7   |  Bbmaj7                  |
    Bm             E7                    |  Amaj7       F#m     |
    Ebm7(b5)  Ab7(b9)           |  Dbmaj7                 |
    C7(#9)        B7(#4)             |  Bbmaj7                 :||
