I'm at the point where I've completed years of scale practice. I also have a decent grasp of theory. I now find myself at a level where I can jam but it's not as "musical" as I like. I base a lot of my jamming around a lick or two and fill a lot. I can "make it sound like music" and it fits in time but is not as melodic as I would like.
How do I make my "jam" more melodic? If I know the song well enough I can get my thoughts and ideas several beats out in front of what notes my hands are playing. I have plenty of time in my head to work on melodic lines in order to get to where I am going but still can't crank melodic lines out on the guitar "on the fly".
Anyone care to share ideas or resources on this? I find the subject of "musical improv" really lacking on the internet. Sure I've found a few good articles here and there, but no "study" or "how to" on it. Again any resources you care to share on the subject would be appreciated.
I'd also be interested in hearing what some of you done in order to propel yourself into the "next level" with jamming when you were where I am today.
