WieWaldi I've never been into blues music, but I really like that piece, it's very relaxing and I thought you played it really well. You look relaxed and you have lovely hands (said from someone whose hands look like knarled talons when playing - I have hand envy!). I didn't perceive any wrong notes so what was "wrong" towards the end seems to have been cleverly covered by your fluid playing.
How long have you been playing piano?
