"Here, I'm going to talk about amplitude and frequency. Now, essentially, if I draw out a wave here, if you start at this point, and you get something like this, the wave. Essentially think about this straight line as a string that's not struck. When you strike the string, it's waving in this kind of pattern as it shakes after you strike it. Now how far it shakes from it's original point, is the amplitude. So it's the distance from it's origin to how far up and down it's moving. Now the frequency is where it would go from this point here to this point here, where it creates one full cycle. Now, as that shrinks, as these wave lengths become closer and closer together, the frequency increases which means that the note is going to get higher in pitch. So a very high note would have a very close frequency. A very low note would have a very wide frequency. And amplitude is essentially loudness. So the further apart this wave is, the more that string is vibrating, the louder it's going to be."
