One of the beauties of the blues jam is the
egalitarianism, where an unknown first time attendee gets the same
number of bars to express themselves as a seasoned pro. You just
have to check your ego at the door. It helps to have a moderator
like Buzz Krantz, who while he can be a big teddy bear, can also
clamp down the thumbscrews when he needs to. I still remember that
look he gave me when I was shouting from the peanut gallery to
extend the solos to 24 bars. Sure shut me up.
Sure, some people find this too intimidating to play. To help with
this, Michael Rubin started a "pre-jam" to help newbies with their
jamming chops and etiquette, and Jimi Lee was running an afternoon
jam that usually had smaller groups. All these things have sprung
up from the grassroots to support the blues jam
Similar things can happen with the jazz jam if there is interest and
participation. I'm not saying that the jazz jams should be
structured this way at all. I like the idea of being able to maybe
sign up, and then call a tune, and share it with one or two or three
other players, rather than spending 30 minutes making the rounds
with one progressions, as the blues jams do. But my point is that
if people are encouraged to participate the jam can find its own
solutions to problems that might arise.
