Musical note

Here would be my definition of the word "note":

• a location in pitch,
• a location in time,
• a location on a musical instrument or
• a symbol for any of the first three.

--Bill Wesley

In music, the term note has three primary meanings:

1. A sign used in musical notation to represent the relative duration and pitch of a sound (♪, ♫);
2. A pitched sound itself.
3. A pitch class.
