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.

(𝄽) may take a different form 
in older music. [1] [2] [3] When an entire bar is devoid of notes, a whole (semibreve) rest is used, regardless of the actual time signature. [4] 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. [5] 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. [6]

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. [7] 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. [8]
Musical notation is any system used to visually represent music. Systems of notation generally represent the elements of a piece of music that are considered important for its performance in the context of a given musical tradition. The process of interpreting musical notation is often referred to as reading music.
A time signature is a convention in Western music notation that specifies how many note values of a particular type are contained in each measure (bar). The time signature indicates the meter of a musical movement at the bar level.
In musical notation, an accidental is a symbol that indicates an alteration of a given pitch. The most common accidentals are the flat and the sharp, which represent alterations of a semitone, and the natural, which cancels a sharp or flat. Accidentals alter the pitch of individual scale tones in a given key signature; the sharps or flats in the key signature itself are not considered accidentals.
A quarter note (American) or crotchet (British) is a musical note played for one quarter of the duration of a whole note. Quarter notes are notated with a filled-in oval note head and a straight, flagless stem. The stem usually points upwards if it is below the middle line of the staff, and downwards if it is on or above the middle line. An upward stem is placed on the right side of the notehead, a downward stem is placed on the left. The Unicode symbol is U+2669.
In music, a half note (American) or minim (British) is a note played for half the duration of a whole note and twice the duration of a quarter note. It was given its Latin name because it was the shortest of the five note values used in early medieval music notation. Half notes are notated with a hollow oval notehead like a whole note and straight note stem with no flags like a quarter note. The half rest denotes a silence of the same duration. Half rests are drawn as filled-in rectangles sitting on top of the middle line of the musical staff, although in polyphonic music the rest may need to be moved to a different line or even a ledger line. As with all notes with stems, half notes are drawn with upward stems on the right when they are below the middle line of the staff and downward stems on the left when they are on or above the middle line. In vocal music, notes on the middle line have a downward stem instead of an upward stem.
An eighth note (American) or a quaver (British) is a musical note played for one eighth the duration of a whole note (semibreve). Its length relative to other rhythmic values is as expected—e.g., half the duration of a quarter note (crotchet), one quarter the duration of a half note (minim), and twice the value of a sixteenth note. It is the equivalent of the fusa in mensural notation.
Sheet music is a handwritten or printed form of musical notation that uses musical symbols to indicate the pitches, rhythms, or chords of a song or instrumental musical piece. Like its analogs – printed books or pamphlets in English, Arabic, or other languages – the medium of sheet music typically is paper. However, access to musical notation since the 1980s has included the presentation of musical notation on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments.
In music, a double whole note (American), breve (British) or double note lasts two times as long as a whole note. It is the second-longest note value still in use in modern music notation. The longest notated note is the longa, which could be double or triple the length of a breve, although its use is most commonly found in early music. The longest notated note is the maxima.
In musical notation, a bar is a segment of music bounded by vertical lines, known as bar lines, usually indicating one of more recurring beats. The length of the bar, measured by the number of note values it contains, is normally indicated by the time signature.
In music, the terms additive and divisive are used to distinguish two types of both rhythm and meter:
Braille music is a braille code that allows music to be notated using braille cells so music can be read by visually impaired musicians. The system was incepted by Louis Braille.
In music, an accent is an emphasis, stress, or stronger attack placed on a particular note or set of notes, or chord, either as a result of its context or specifically indicated by an accent mark. Accents contribute to the articulation and prosody of a performance of a musical phrase. Accents may be written into a score or part by a composer, or added by the performer as part of their interpretation of a musical piece.
The numbered musical notation is a cipher notation system used in Mainland China, Taiwan, Hong Kong, and to some extent in Japan, Indonesia, Malaysia, Australia, Ireland, the United Kingdom, the United States and English-speaking Canada. It dates back to the system designed by Pierre Galin, known as Galin-Paris-Chevé system. It is also known as Ziffernsystem, meaning "number system" or "cipher system" in German.
A fermata is a symbol of musical notation indicating that the note should be prolonged beyond the normal duration its note value would indicate. Exactly how much longer it is held is up to the discretion of the performer or conductor, but twice as long is common. It is usually printed above but can be occasionally below the note to be extended.
Mensural notation is the musical notation system used for polyphonic European vocal music from the late 13th century until the early 17th century. The term "mensural" refers to the ability of this system to describe precisely measured rhythmic durations in terms of numerical proportions between note values. Its modern name is inspired by the terminology of medieval theorists, who used terms like musica mensurata or cantus mensurabilis to refer to the rhythmically defined polyphonic music of their age, as opposed to musica plana or musica choralis, i.e., Gregorian plainchant. Mensural notation was employed principally for compositions in the tradition of vocal polyphony, whereas plainchant retained its own, older system of neume notation throughout the period. Besides these, some purely instrumental music could be written in various forms of instrument-specific tablature notation.
In musical notation, a beam is a horizontal or diagonal line used to connect multiple consecutive notes to indicate rhythmic grouping. Only eighth notes (quavers) or shorter can be beamed. The number of beams is equal to the number of flags that would be present on an unbeamed note. Beaming refers to the conventions and use of beams. A primary beam connects a note group unbroken, while a secondary beam is interrupted or partially broken.
Tonic sol-fa is a pedagogical technique for teaching sight-singing, invented by Sarah Ann Glover (1785–1867) of Norwich, England and popularised by John Curwen, who adapted it from a number of earlier musical systems. It uses a system of musical notation based on movable do solfège, whereby every note is given a name according to its relationship with other notes in the key: the usual staff notation is replaced with anglicized solfège syllables or their abbreviations. "Do" is chosen to be the tonic of whatever key is being used. The original solfège sequence started with "Ut", the first syllable of the hymn Ut queant laxis, which later became "Do".
In music, a 1/16, sixteenth note (American) or semiquaver (British) is a note played for half the duration of an eighth note (quaver), hence the names. It is the equivalent of the semifusa in mensural notation, first found in 15th-century notation.
Systems of musical notation have been in use in China for over two thousand years. Different systems have been used to record music for bells and for the Guqin stringed instrument. More recently a system of numbered notes (Jianpu) has been used, with resemblances to Western notations.
