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 ...
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
A number of dots (n) lengthen the note value by 2 n − 1 / 2 n its value, so two dots add two lower note values, making a total of one and three quarters times its original duration. The rare three dots make it one and seven eighths the duration, and so on.
A quarter note or crotchet (/ ˈ k r ɒ t ʃ ɪ t /) is a musical note played for one quarter of the duration of a whole note (or semibreve). Quarter notes are notated with a filled-in oval note head and a straight, flagless stem .
The duration (note length or note value) is indicated by the form of the note-head or with the addition of a note-stem plus beams or flags. A stemless hollow oval is a whole note or semibreve, a hollow rectangle or stemless hollow oval with one or two vertical lines on both sides is a double whole note or breve.
Because of that, all notes with these kinds of relations can be grouped under the same pitch class and are often given the same name. The top note of a musical scale is the bottom note's second harmonic and has double the bottom note's frequency. Because both notes belong to the same pitch class, they are often called by the same name.
The system of note types used in mensural notation closely corresponds to the modern system. The mensural brevis is nominally the ancestor of the modern double whole note (breve); likewise, the semibrevis corresponds to the whole note (semibreve), the minima to the half note (minim), the semiminima to the quarter note (crotchet), and the fusa to the eighth note (quaver).
A related symbol is the whole rest (or semibreve rest), which signifies a rest for the duration of a whole note. Whole rests are drawn as filled-in rectangles generally hanging under the second line from the top of a musical staff , though they may occasionally be put under a different line (or ledger line ) in more complicated polyphonic ...
