Life without playing music is inconceivable for me.

-Albert Einstein

To stop the flow of music would be like the stopping of time itself, incredible and inconceivable.

-Aaron Copland

• What is music?

• How would you define it in physical terms?

Pure listening

pleasure: Auditorium design

Sound waves/vibrations

You and a friend are riding the Ferris wheel. How would you plot your height above the ground vs time as the ferris wheel turns? The wheel has a radius of 20m, and you complete one trip around the wheel every two minutes.

Height (m)

Time (min)

Period

Simple Harmonic Motion: Basic Definitions

A = amplitude

T = period

f = 1/T = frequency

x(t) = displacement/position as a function of time

x(t)

Analogy of diving board in musical setting = ?

Musical note “dies out”

Zoomed in (17 msec)

t

Decay time: where amplitude of signal drops to e-1of the max amplitude = ~37% of max amplitude

What’s all this got to do with music?!

• Introduction: what you are studying and why

• Methods: what you did and how it works-- theory and techniques described in detail

• Results: what you observed

• Discussion: what it all means
