The Physics of Pitch in music

Consider the concept of pitch in more detail, using its physical basis. We have already agreed that we are only interested in musical sound, and it has a pronounced fundamental oscillation frequency. Let’s just look at it on the charts:

Chart 1

Lower sound wave

Graph 1. Wave of a lower sound

And another graph:

Chart 2

Wave of a higher sound

Graph 2. Wave of higher sound

It can be seen that the oscillation frequency in graph 1 is lower than in graph 2. The sound corresponding to graph 1 will also be lower than the sound shown in graph 2.

Listen to sound examples.
