In Western musical notation, the staff or stave (UK) is a set of five horizontal lines and four spaces that each represent a different musical pitch or in the case of a percussion staff, different percussion instruments. Appropriate music symbols, depending on the intended effect, are placed on the staff according to their corresponding pitch or function. Musical notes are placed by pitch, percussion notes are placed by instrument, and rests and other symbols are placed by convention.
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.
A whole note (American) or semibreve (British) in musical notation is a single note equivalent to or lasting as long as two half notes or four quarter notes.
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.
In music, the dynamics of a piece are the variation in loudness between notes or phrases. Dynamics are indicated by specific musical notation, often in some detail. However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece. The execution of dynamics also extends beyond loudness to include changes in timbre and sometimes tempo rubato.
In music, a double whole note (American), breve, 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 music, a thirty-second note (American) or demisemiquaver (British) is a note played for 1⁄32 of the duration of a whole note. It lasts half as long as a sixteenth note and twice as long as a sixty-fourth.
In Western musical notation, a dotted note is a note with a small dot written after it. In modern practice, the first dot increases the duration of the basic note by half of its original value. This means that a dotted note is equivalent to writing the basic note tied to a note of half the value – for instance, a dotted half note is equivalent to a half note tied to a quarter note. Subsequent dots add progressively halved value, as shown in the example to the right.
In music, a hundred twenty-eighth note or semihemidemisemiquaver or quasihemidemisemiquaver (British) is a note played for 1⁄128 of the duration of a whole note. It lasts half as long as a sixty-fourth note. It has a total of five flags or beams.
In music notation, a note value indicates the relative duration of a note, using the texture or shape of the notehead, the presence or absence of a stem, and the presence or absence of flags/beams/hooks/tails. Unmodified note values are fractional powers of two, for example one, one-half, one fourth, etc.
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.
A longa, long, quadruple note (Am.), or quadruple whole note is a musical note that could be either twice or three times as long as a breve, four or six times as long as a semibreve, that appears in early music. The number of breves in a long was determined by the "modus" or "mode" of a passage. Sections in perfect mode used three breves to the long while sections in imperfect mode used two breves to the long. Imperfect longs, worth two breves, existed in perfect mode from the earliest sources, while the fourteenth century saw the introduction of perfect longs, worth three breves, in imperfect mode through the use of dots of addition.
In musical notation, tenuto, denoted as a horizontal bar adjacent to a note, is a direction for the performer to hold or sustain a note for its full length.
In music, a notehead is the part of a note, usually elliptical in shape, whose placement on the staff indicates the pitch, to which modifications are made that indicate duration. Noteheads may be the same shape but colored completely black or white, indicating the note value. In a whole note, the notehead, shaped differently than shorter notes, is the only component of the note. Shorter note values attach a stem to the notehead, and possibly beams or flags. The longer double whole note can be written with vertical lines surrounding it, two attached noteheads, or a rectangular notehead. An "x" shaped notehead may be used to indicate percussion, percussive effects, or speaking. A square, diamond, or box shaped notehead may be used to indicate a natural or artificial harmonic. A small notehead can be used to indicate a grace note.
Percussion notation is a type of musical notation indicating notes to be played by percussion instruments. As with other forms of musical notation, sounds are represented by symbols which are usually written onto a musical staff.
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.
In music, a two hundred fifty-sixth note, or occasionally demisemihemidemisemiquaver (British), is a note played for 1⁄256 of the duration of a whole note. It lasts half as long as a hundred twenty-eighth note and takes up one quarter of the length of a sixty-fourth note. In musical notation it has a total of six flags or beams. Since human pitch perception begins at 20 Hz (1200/minute), then a 256th-note tremolo becomes a single pitch in perception at quarter note ≈ 18.75 bpm.
