Could you help me figure out the notes to this?

[tranquillis]

I really want to learn this. (in spit of its 12 second length) It's Frasier playing an improvised song; I originally thought it might be something by Michael Nyman, or the Heart Asks Pleasure First, but it is in fact an improvisation. Here's the clip-

This is what i've come up with so far- (Commas seperate notes, Notes played together have no comma seperating them)

In order:
D,A (below middle C, down a fourth)
F,G,A, (above middle c)
A,D (same as first in reverse)
B Flat, (Above middle C)
B Flat D (B flat above middle c, D about a 7th below middle C, both played together)
F, B Flat (above D from previous)
A (just below B flat from previous), Left hand plays F, B flat
Right hand: G, F, F (below  

Sorry for the crude transcription, but this might help you learn the beginning quicker, could you post notes to the rest of the song?

Very grateful for this

Trying using chords to get the harmonic progression first.  Then picking out notes will be easier.

Dm, BbM7, Dm/A, A, Dm

Penultimate chord seemed ambiguous to me.  Could have C# or not (could be implied).  Could be A11 without 3rd.
