I have quite a bit of sheet music that I enjoy using. Music to popular songs that give me the chords and melody line that I understand pretty well. But they never write those little "dittys, riffs" or whatever they're called that is played in those longer dead spaces between the melody notes. Sheet music just gives a long rest in these spots and then goes to the next melody line. I can hear these lines in the back of my head and they're in almost every song you hear, but I can't play this on my own. If I have the music, I can play it, but it's almost never written. I think that this adds so much to a song. How does one start to come up with little fill-ins on your own? Is it some type of COTM thing? If so, what are some suggestions in coming up with this type of thing?
thanks in advance,
