Pardon, but this is no sonata...
I would call it "free improvisation"....
if it´s self played than I wonder the different tunes of the piano, and why you couldn´t find a real ending...
a little bit helpless...
Frantzi
Beginning: until approx 1:40 great Konzert-Piano
than: + Electric Piano, 2:02 changing to mellow Piano with to much echo....ca. 2:28 back to E-Piano,
at the Ending (?) similar to Kozert+EPiano...
The melody could be fine, when accurate played and the tunes should be modified with pedals and the strongness of the key-touch....

Franz
