In music, a musical note, otherwise referred to as a musical tone, melodical note or melodical tone or simply a music note, music tone, melodic note, melodic tone, note or tone, is a text character that represents a sound of a writing system known as a solfège, especially in the United States, which is similar to a syllable in a spoken language. For example, in the first two lines of the song "Twinkle, twinkle, little star, how I wonder what you are" there are 14 notes: one for each syllable.
Confusingly, the word "note" can also mean the pitch of a note (how high or low it is). For example: the whole of the song "Twinkle, twinkle, little star" can be played using six different notes: C, D, E, F, G and A.
The word "note" can also mean the written symbol of the note, which shows the note value.
Nearly all music is made up of notes. Music without notes might be sound effects.
