## Jazz Math

BY BILL ANSCHELL

If x is the number of chord changes in a tune, and y is the tempo at which it is played, then xy = factor by which a guitarist will turn down his amp.

# (notes/measure played by a saxophonist on a ballad) is proportional to # (drinks he has consumed).

4 + 4.125 + 4 + 3.875 + 4 + (4 6 .667) + 4 + (x, where x is unknown) = 1 chorus trading with drummer.

(2 + 5 + 1) (# of freshman college jazz students, internationally) = annual income of Jamie Aebersold, in dollars.

Infinity = (3 + 6 + 2 + 5) + (3 + 6 + 2 + 5) + (3 + 6 + 2 + 5) …

5/4 + 7/4 + 11/4 = drummer’s gig

If (# of drinks consumed, per musician) > (# of drinks comped by club), then unrest will prevail unless (cost per drink) < 1/20 (pay for gig).

1 uptempo tune +1 rushing drummer + x (double lattes) = x (fights among horn players to solo first)

1 ballad + 1 dragging drummer + x (Percocets) = 1 cleared house, where x is proportional to the speed at which the room empties

Jam session + eighth-note rest = missed opportunity.
Jam session + (quarter-note rest or greater) = band on break.

{(New + York) squared – (NewNew + Yorkyork + Yorknew) + New York + 2 (Ride + Sally) – Sally} divided by (less than five seconds) = medley from hell

(1/vocalist’s experience in years) (# of beats per measure) x 32 = # of unintended modulations + skipped beats, per chorus.

If x = piano’s deviance from being in tune, y = volume level of drummer, = length of gig, and d = number of drinks consumed by pianist on break, then (d) (xyz/pay of the gig, in dollars), predicts the probability of pianist urinating in his instrument.

Vow of Poverty theorem:  If # people in audience < # of musicians on bandstand, then pay per musician < one individual cover charge.

Bass theorem:  A musician’s IQ is inversely proportional to the size of his/her instrument, and directly related to the register of the instrument.

Rule of One theorem:  Universe of jazz vocalists 4 # of jazz vocalists who sing “Summertime”= 1 = rank of “Summertime” among tunes most despised by instrumentalists

“Devil’s Music” theorem:  Smooth Jazz = square root of all evil.

“Two Americas” Buffet theorem:  Fresh salmon/flaccid spanakopita + prime rib/limp eggrolls + jumbo shrimp/soggy chicken fingers = high society gig/Elks Club gig

“Cream Sinks to the Bottom Theorem”:  A musician’s ability to find and keep a gig - solo or as a leader - is inversely related to his musical talent.

How much should a gig pay, based on the following conditions:  drive 90 miles outside of town through pouring rain; set up two hours in advance; load in through slimy kitchen accessed by treacherous outdoor staircase; and play four hours of continuous crappy dance favorites for drunk rich people?

Would you take it for 1/2 that much?

(If yes):  Desperation/pride > 1

After you bid on the above gig for 1/3 your worth, a college student offers to play the same gig for 1/2 as much.  You are 12 times as good as him, but 1/2 as good-looking. The client has a tin ear.  Who will get the job?  Why do you bother practicing?

If a trumpet player counts off a tune in 4/4 at mm = 180, and the drummer slows it down at a constant rate of deceleration over 8 measures to mm = 150, does the pianist still suck?

If a bassist plays a root, a pianist superimposes a major seventh chord built on the fifth, and a saxophonist plays the 13th, will attractive women notice? Will the drummer?

If a successful attorney earns 3x as much as a successful musician, but the musician believes his work is 4x as fulfilling, who actually has larger genitalia?

Your trio is set up in a perfect equilateral triangle.  A singer sets up exactly in the middle.  Will the three of you be divided against the singer, or against one another?

If (% of Americans who like jazz) < (% of Americans who like chainsaw sculptures), what is America’s most important indigenous art form?
