In the last few months, I realized that for quite some time now, I've been avoiding one specific area of practice - Simply playing a backing track of a tune and improvising over it in real time. Strange that I would do all these other things such as lick/phrase connection out of time, transcribing solos, developing lick/phrase ideas, etc, yet exclude the rather important practice of ACTUALLY improvising like I'm jamming. So, as I've begun to focus on practicing real time, to the music improvising, I'm hungering for different exercises to strengthen weaknesses I have. Here are a few I've been dabbling with already.
1)Straight improvising with no rules
2)Improvising in specific "zones" of the guitar neck (like between frets 0 and 7 only)
3)Chord comping only.
4)Octave comping only.
5)continuous eighth notes only
What other real time improvisation exercises have you done that have worked?
