Answer 1

Although they are commonly labeled with letters, **musical notes** can also be measured by sound waves per second using Hertz (Hz). Each musical note corresponds to a specific frequency, allowing for quantifiable measurements in terms of sound waves. For example, the note A4 (the A above middle C) is often tuned to 440 Hz.
