I'm not sure where to post this but this is concerning piano licks and improvisation. Now this is sort of hard to explain but I'll try my best.
When I listen to R&B songs such as Justin Timberlake - Still on my Brain I noticed that there are small piano licks in the background. They're usually licks that aren't part of the key but sound perfectly in the song. It just adds to overall ambiance and sound. I just don't know where to start as far as melodies. I've tried a few but they don't work as well as the ones I'm hearing. They sound even too complicated even to try to play it by ear, much like trying to copy live improvisation. I was thinking there might be websites where I might be able to find these licks but all I found were blues improvisation. I know this might seem a bit random, but its something that has really baffled me for many months now. If you guys can help me out and point me in the right direction I'd appreciate it. Thanks.
I also hope you know what I'm talking about lol.
