To stop the flow of music would be like the stopping of time itself, incredible and inconceivable.
It’s all in your head: psycho-acoustics

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.
A = amplitude
T = period
f = 1/T = frequency
x(t) = displacement/position as a function of time
Analogy of diving board in musical setting = ?
Musical note “dies out”
Zoomed in (17 msec)
Decay time: where amplitude of signal drops to e-1of the max amplitude = ~37% of max amplitude
