MUSIC AND WAVES: frequency

How can we change the frequency in musical instrument?

Frequency relates to how many times a wave cycles from a crest (top) to a node (middle) to a trough (bottom) to a node and to the next crest in one second (it can be measured in other units of time too, but seconds are more common since frequency is measured in Hertz (Hz) and one Hz is a “1/second”).
