If you've got good musicians, jamming can be great fun & very rewarding.
[/quote] Well in my own experience, jamming may also be particularly rewarding when you are not great musicians.

My understanding of jamming coincides with Blue's observation. Some friends would get into a room with no pre-planned song list; someone randomly starts playing a pattern, a riff or some chords and everyone else follows along. Over time the 'song' mutates, winds down, re-starts, wanders off and comes back.

100% agreed. In my former band, we all had different musical backgrounds and some of us had little experience in playing in a band. We always reserved half an hour for jamming at the beginning of our rehearsals. The drummer started with a pattern, then I played a very simple bass line, and the guitarists followed. Then, when everything was in place, the drummer or myself progressively changed the rythm/energy, so that the atmosphere of the music was completely changed. It's a very efficient way to learn and play together, listen to each other, communicate through sound changes and discreet visual signs, and explore the different sort of music we can play around three notes. Now you can't always avoid a wobbly guitar solo but that's fine. We bassists have to be generous towards our less fortunate fellows. Of course, the rythmic section also needs to be authoritarian from time to time and the jamming session is a good way to establish the balance of power in a band.
