Some musical notations are symbols used to indicate the duration, pitch, and other aspects of a piece of music. The most common notation is the rest, which is a symbol that indicates a PAUSE in the music. A rest is usually represented by a five-letter word, such as 'PAUSE' or 'SILENT'. Other notations include notes, which indicate the pitch of a sound, and dynamics, which indicate the volume of a sound. Additionally, there are symbols for tempo, articulation, and ornamentation. All of these symbols are used to create a complete musical composition.
