Visual Representation of oscillation

A 'star drop': the patterns created when a drop, flattened by some force, is excited into shape mode oscillations

Notes in keys, with their associated frequency

Generally most music you hear is within the key '4' on this chart. "Middle C" is generally C4 and is one of the more common notes in music. For more information on this, and as a follow up for another post, check this link.
