Hearing When A String Is In Or Out Of Tune
Cycles

To understand how to tune it helps if you can see how a note looks in a graphical view. To the right you can see the animation showing what looks like waves (these waves are known as cycles). When a note is sounded it makes vibrations in the air, this is how those vibrations are represented visually. The lower the note the further away the cycles are. When the pitch of the note is higher, the cycles are closer together.
