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.
Trumpet: Trumpet players are image-conscious and walk with a swagger. They are often former college linebackers. Trumpet players are very attractive to women, despite the strange indentation on their lips. Many of them sing; misguided critics then compare them to either Louis Armstrong or Chet Baker depending whether they're black or white. (IH: 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). IH: The vocalist will try to seduce youand the rest of the audienceby 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."
Trombone: The trombone is known for its pleading, voice-like quality. "Listen," it seems to say in the male tenor range, "Why won't anybody hire me for a gig?" Trombonists like to play fast, because their notes become indistinguishable and thus immune to criticism. Most trombonists played trumpet in their early years, then decided they didn't want to walk around with a strange indentation on their lips. Now they hate trumpet players, who somehow get all the women despite this disfigurement. Trombonists are usually tall and lean, with forlorn faces. They don't eat much. They have to be very friendly, because nobody really needs a trombonist. Talk to a trombonist during a break and he'll ask you for a gig, try to sell you insurance, or offer to mow your lawn.
Now that you know a little bit about the room and the players, it's time to turn your attention to the music. Your new-found knowledge will give you astonishing insights. Let's look at some typical session landmarks:
Picking the Tune
Every time a tune ends, someone has to pick a new one. That's a fundamental concept that, unfortunately, runs at odds with jam session group processes.
Tune selection makes a huge difference to the musicians. They love to show off on tunes that feel comfortable, and they tremble at the threat of the unknown. But to pick a tune is to invite close scrutiny: "So this is how you sound at your best. Hmm..." It's a complex issue with unpredictable outcomes. Sometimes no one wants to pick a tune, and sometimes everyone wants to pick a tune.
The resulting disagreements lead to faction-building andunder extreme conditionseven impromptu elections. The politics of tune selection makes for some of the session's best entertainment.
