Great song its not out of tune like the other guy said its more like some great classical piece. I wish i could compose classical music like this i might get inspired by this piece.
Out of tune notes are NOT minor errors. 35 seconds was more than enough for me. Sorry :(
Try listening to jazz and blues sometime, your ears could use that "all-ears" ;)
Please contact me if you would like to use this in a project. We can discuss the details.
