Playing the Market
Playing the Market is a
recent experimental music recording by Emerald
Suspension. The project features audio compositions based on patterns found in
the stock market and in economic data.

the Market integrates concepts, structure, and source data as part of each
arrangement. The resulting tracks range from minimalist orchestral pieces
to conceptual industrial audio art. The structural components of some of the pieces in the collection are summarized below:
- "Long Bond" is a
requiem string solo. Notes in this piece are based on the pattern of interest
rates since 1926 as represented by the yield of the 30-year Treasury
bond. Higher notes equate to higher interest rates and lower notes
reflect the lower rates experienced over time.
- "Irrational Exuberance /
Great Depression" is a composition for piano that reflects the
investor psychology that drives the stock market and the economy as a
whole. Notes and expression changes are determined by the
historical patterns of the Consumer
Confidence Index. Major chords indicate long term shifts and minor
chords denote short-term shifts in consumer confidence. Changes in the
tempo of the piano solo correspond to historical changes in the index
value. The background sound is a piece of musique concrete featuring
the processed sounds of an antique ticker tape machine.
- "Fibonacci's Random Walk"
is algorithmic music interspersed throughout the recording. The piece is
inspired by two competing theories about the pattern of stock market
returns. Some theories hold that stock prices follow predictable patterns
and others state that markets are efficient, with price changes following a
'random walk'. One specific theory about stock price patterns states that
patterns are governed by cycles founded upon the Fibonacci
number series (1-1-2-3-5-8…). The instrumentation, pitch, and duration of
notes in this composition are based on that number series - Then, random
deviations from that specific pattern are inserted throughout the
performance to represent the efficient
- "Bulls and Bears of the World"
includes percussion parts inspired by the historical price patterns of
various global stock
markets. The melody represents the returns of the aggregation of the
world stock markets. Audio samples of bulls and bears are inserted at the
appropriate points in time to represent notable global stock price increases
- "Industrial Century"
is an orchestral composition based on 100 years of daily stock market data.
Long, intermediate, and short-term trends in the US stock
market over the course of the 20th century are represented in the piece.
Changes in pitch follow the pattern of high and low returns of the stock
market while the dynamics of the various parts included in the arrangement
are appropriately determined by market trading
- "The Misery Index"
is an experimental recording based on the historical patterns of inflation
and unemployment. Just as some
economists add these two economic indicators together to arrive at a 'misery
index', this composition combines audio representations of each. The
instrumentation mixes tuned synthesized noise and bowed metal to set an
appropriately "dismal" tone.
- "National Debt" is
an audio representation of the US
National Debt as experienced over more than 200 years. Audio events
based on debt increases result in a 'rain chime' effect at the beginning of
the piece, progressing to the level of a storm by the end.
- "Stock Options" is
an experimental audio composition based on the Black-Scholes
option pricing model and the Put-Call Parity Theorem. The composition is
based on stock price, volatility, and interest rate data from 1938 to 1995,
the life span of Fischer Black, co-creator of the landmark option pricing
formula. The two parts of the composition represent the theoretical price
changes of a call option and of a put option on the U.S. stock market over
- "IPO" layers music over a collage of audio samples
representing money and risk taking, including sounds of an active stock
exchange trading floor and those of a casino.
