While a jazz artist may claim to have a "unique voice" on his instrument, sociological analysis tells us otherwise. In reality, jazz players are simply the embodiment of instrumental archetypes. Jam sessions, then, are the playing-out of archetypal conflicts. Jazz "standards" performed at the sessions make up the script. Over time, an epic play is realized. Here are the characters:
Bass: Bassists are not terribly smart. The best bassists come to terms with their limitations by playing simple lines and rarely soloing. During the better musical moments, a bassist will pull his strings hard and grunt like an animal. Bass players are built big, with paws for hands, and they are always bent over awkwardly. If you talk to the bassist during a break, you will not be able to tell whether or not he’s listening.
Drums: Drummers are radical. Specific personalities vary, but are always extreme. A drummer might be the funniest person in the world, or the most psychotic, or the smelliest. Drummers are uneasy because of the many jokes about them, most of which stem from the fact that they aren’t really musicians. Pianists are particularly successful at making drummers feel bad. Most drummers are highly excitable; when excited, they play louder. If you decide to talk to the drummer during a break, be careful not to sneak up on him.
Saxophone: Saxophonists think they are the most important players on stage. Consequently, they are temperamental and territorial. They know all the Coltrane and Bird licks but have their own sound, a mixture of Coltrane and Bird. They take exceptionally long solos, which reach a peak half way through and then just don’t stop. They practice quietly but audibly while other people are trying to play. They are obsessed. Saxophonists sleep with their instruments, forget to shower, and are mangy. If you talk to a saxophonist during a break, you will hear a lot of excuses about his reeds.
Arrive at the session early, and you may get to witness the special trumpet game. The rules are: play as loud and as high as possible. The winner is the one who plays loudest and highest. Caution: It is loud and high. If you talk to a trumpet player during a break, he might confess that his favorite player is Maynard Ferguson, the merciless God of loud-high trumpeting.
Guitar: Jazz guitarists are never very happy. Deep inside they want to be rock stars, but they’re old and overweight. In protest, they wear their hair long, prowl for groupies, drink a lot, and play too loud. Guitarists hate piano players because they can hit ten notes at once, but guitarists make up for it by playing as fast as they can. The more a guitarist drinks, the higher he turns his amp. Then the drummer starts to play harder, and the trumpeter dips into his loud/high arsenal. Suddenly, the saxophonist’s universe crumbles, because he is no longer the most important player on stage. He packs up his horn, nicks his best reed in haste, and storms out of the room. The pianist struggles to suppress a laugh. If you talk to a guitarist during the break he’ll ask intimate questions about your 14-year-old sister.
Vocals: Vocalists are whimsical creations of the all-powerful jazz gods. They are placed in sessions to test musicians’ capacity for suffering. They are not of the jazz world, but enter it surrepticiously. Example: A young woman is playing minor roles in college musical theater. One day, a misguided campus newspaper critic describes her singing as "...jazzy." Voila! A star is born! Quickly she learns "My Funny Valentine," "Summertime," and "Route 66." Her training complete, she embarks on a campaign of session terrorism. Musicians flee from the bandstand as she approaches. Those who must remain feel the full fury of the jazz universe (see "The Vocalist" below). I.H.: The vocalist will try to seduce you - and the rest of the audience - by making eye contact, acknowledging your presence, even talking to you between tunes. DO NOT FALL INTO THIS TRAP! Look away, your distaste obvious. Otherwise the musicians will avoid you during their breaks. Incidentally, if you talk to a vocalist during a break, she will introduce you to her "manager."
