A rest is the absence of a sound for a defined period of time in music, or one of the musical notation signs used to indicate that.
The length of a rest corresponds with that of a particular note value, thus indicating how long the silence should last. Each type of rest is named for the note value it corresponds with (e.g. quarter note and quarter rest, or quaver and quaver rest), and each of them has a distinctive sign.
Rests are intervals of silence in pieces of music, marked by symbols indicating the length of the silence. Each rest symbol and name corresponds with a particular note value, indicating how long the silence should last, generally as a multiplier of a measure or whole note.
|Double whole rest
When an entire bar is devoid of notes, a whole (semibreve) rest is used, regardless of the actual time signature. Historically exceptions were made for a 4
2 time signature (four half notes per bar), when a double whole (breve) rest was typically used for a bar's rest, and for time signatures shorter than 3
16, when a rest of the actual measure length would be used. Some published (usually earlier) music places the numeral "1" above the rest to confirm the extent of the rest.
Occasionally in manuscripts and facsimiles of them, bars of rest are sometimes left completely empty and unmarked, possibly even without the staves.
In instrumental parts, rests of more than one bar in the same meter and key may be indicated with a multimeasure rest (British English: multiple bar rest), showing the number of bars of rest, as shown. A multimeasure rest is usually drawn in one of two ways:
The number of bars for which a horizontal line multimeasure rest lasts is indicated by a number printed above the musical staff (usually at the same size as the numerals in a time signature). If a change of meter or key occurs during a multimeasure rest, that rest must be divided into shorter sections for clarity, with the changes of key and/or meter indicated between the rests. Multimeasure rests must also be divided at double barlines, which demarcate musical phrases or sections, and at rehearsal letters.
A rest may also have a dot after it, increasing its duration by half, but this is less commonly used than with notes, except occasionally in modern music notated in compound meters such as 6
8 or 12
8. In these meters the long-standing convention has been to indicate one beat of rest as a quarter rest followed by an eighth rest (equivalent to three eighths). See: Anacrusis.
In a score for an ensemble piece, "G.P." (general pause) indicates silence for one bar or more for the entire ensemble. Specifically marking general pauses each time they occur (rather than writing them as ordinary rests) is relevant for performers, as making any kind of noise should be avoided there—for instance, page turns in sheet music are not made during general pauses, as the sound of turning the page becomes noticeable when no one is playing.
