    Low notes produce larger and longer sound waves (meaning there is more distance between the crest and trough of each wave). High notes have a much faster pulse than lower notes and shorter sound waves.

    • Spot on. Adding just a little more....each note cycles a certain amount per second. A=440 means the sound wave repeats its self 440 times per second. Higher notes repeat more times and lower notes fewer.
