In music, notes are distinct and isolatable sounds that act as the most basic building blocks for nearly all of music. This discretization facilitates performance, comprehension, and analysis. Notes may be visually communicated by writing them in musical notation.
Notes can distinguish the general pitch class or the specific pitch played by a pitched instrument. Although this article focuses on pitch, notes for unpitched percussion instruments distinguish between different percussion instruments (and/or different manners to sound them) instead of pitch. Note value expresses the relative duration of the note in time. Dynamics for a note indicate how loud to play them. Articulations may further indicate how performers should shape the attack and decay of the note and express fluctuations in a note's timbre and pitch. Notes may even distinguish the use of different extended techniques by using special symbols.
The term note can refer to a specific musical event, for instance when saying the song "Happy Birthday to You", begins with two notes of identical pitch. Or more generally, the term can refer to a class of identically sounding events, for instance when saying "the song begins with the same note repeated twice.
