An eighth note (American) or a quaver (British) is a musical note played for one eighth the duration of whole note (semibreve), hence the name. This amounts to twice the value of the sixteenth note (semiquaver). It is half the duration of a quarter note (crotchet), one quarter the duration of a half note (minim), one eighth the duration of whole note (semibreve), one sixteenth the duration of a double whole note (breve), and one thirty-second the duration of a longa. It is the equivalent of the fusa in mensural notation ( Morehen and Rastell 2001 )

American English Set of dialects of the English language spoken in the United States

American English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. American English is considered one of the most influential dialects of English globally, including on other varieties of English.

British English is the standard dialect of English language as spoken and written in the United Kingdom. Variations exist in formal, written English in the United Kingdom. For example, the adjective wee is almost exclusively used in parts of Scotland and Ireland, and occasionally Yorkshire, whereas little is predominant elsewhere. Nevertheless, there is a meaningful degree of uniformity in written English within the United Kingdom, and this could be described by the term British English. The forms of spoken English, however, vary considerably more than in most other areas of the world where English is spoken, so a uniform concept of British English is more difficult to apply to the spoken language. According to Tom McArthur in the Oxford Guide to World English, British English shares "all the ambiguities and tensions in the word 'British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity".

Whole note musical note duration

In music, a whole note (American) or semibreve (British) is a note represented by a hollow oval note head and no note stem. Its length is equal to four beats in 4
4
time, that is the whole 4
4
measure. Most other notes are fractions of the whole note.

Eighth notes are notated with an oval, filled-in note head and a straight note stem with one flag note flag (see Figure 1). The stem is placed to the right of the notehead and extends upwards if the notehead lies below the middle line of the staff, and to the left of the notehead extending downwards if the notehead lies on or above the middle line of the staff, in instrumental notation. In vocal music, a middle-line notehead extends upward instead of downward. A related symbol is the eighth rest (or quaver rest), which denotes a silence for the same duration ( Anon. 2016 ).

In Unicode, the symbols U+266A (♪) and U+266B (♫) are an eighth note and beamed pair of eighth notes respectively. The two symbols are inherited from the early 1980s code page 437, where they occupied codes 13 and 14 respectively. Additions to the Unicode standard also incorporated additional eighth note depictions from Japanese emoji sets: ascending eighth notes (U+1F39C, 🎜), descending eighth notes (U+1F39D, 🎝), a graphical generic musical note generally depicted as an eighth note (U+1F3B5, 🎵), and three unconnected eighth notes in sequence (U+1F3B6, 🎶). Unicode's Musical Symbols block includes several variations of the eighth note; these are the versions intended to be used in computerized musical notation (as opposed to the others, which are graphical dingbats).

Unicode Character encoding standard

Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The standard is maintained by the Unicode Consortium, and as of May 2019 the most recent version, Unicode 12.1, contains a repertoire of 137,994 characters covering 150 modern and historic scripts, as well as multiple symbol sets and emoji. The character repertoire of the Unicode Standard is synchronized with ISO/IEC 10646, and both are code-for-code identical.

Code page 437

Code page 437 is the character set of the original IBM PC. It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. The set includes ASCII codes 32–126, extended codes for accented letters (diacritics), some Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII".

Emoji ideograms or smileys used in electronic messages and webpages

Emojis are ideograms and smileys used in electronic messages and web pages. Emoji exist in various genres, including facial expressions, common objects, places and types of weather, and animals. They are much like emoticons, but emoji are actual pictures instead of typographics. Originally meaning pictograph, the word emoji comes from Japanese e + moji; the resemblance to the English words emotion and emoticon is purely coincidental. The ISO 15924 script code for emoji is Zsye.

Tremolo

In music, tremolo, or tremolando, is a trembling effect. There are two types of tremolo.

Quarter note musical note duration

A quarter note (American) or crotchet (British) is a note played for one quarter of the duration of a whole note. Often, musicians will say that a crotchet is one beat, but this is not always correct, as the beat is indicated by the time signature of the music; a quarter note may or may not be the beat. 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 stave or downwards if it is on or above the middle line. However, the stem direction may differentiate more than one part. The head of the note also reverses its orientation in relation to the stem.

Half note musical note duration

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. In time signatures with 4 as the bottom number, such as 4
4
or 3
4
, the half note is two beats long. However, when 2 is the bottom number, the half note is one beat long.

Double whole note musical note duration

In music, a double whole note (American), breve (international), or double note is a note lasting two times as long as a whole note. It is the second-longest note value still in use in modern music notation.

Thirty-second note musical note duration

In music, a demisemiquaver (British) or thirty-second note (American) is a note played for ​132 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 music notation, a sixty-fourth note (American), or hemidemisemiquaver or semidemisemiquaver (British), sometimes called a half-thirty-second note, is a note played for half the duration of a thirty-second note, hence the name. It first occurs in the late 17th century and, apart from rare occurrences of hundred twenty-eighth notes (semihemidemisemiquavers) and two hundred fifty-sixth notes (demisemihemidemisemiquavers), it is the shortest value found in musical notation.

In music, a tuplet is "any rhythm that involves dividing the beat into a different number of equal subdivisions from that usually permitted by the time-signature ". This is indicated by a number, indicating the fraction involved. The notes involved are also often grouped with a bracket or a slur.

Hundred twenty-eighth note musical note duration

In music, a hundred twenty-eighth note or semihemidemisemiquaver or quasihemidemisemiquaver is a note played for ​1128 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. Since human pitch perception begins at 20 Hz (1200/minute), then a 128th-note tremolo becomes a single pitch in perception at quarter note ≈ 160 bpm.

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 his or her interpretation of a musical piece. By default, in the music notation program Sibelius, "accents boost the dynamic by 50%."

Note value sign that indicates the relative duration of a note

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 musical notation system used for European vocal polyphonic music

Mensural notation is the musical notation system used for European vocal polyphonic music from the later part of the 13th century until about 1600. 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.

Beam (music) thick line used to connect notes in musical 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.

Longa (music) musical note

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.

Tenuto is a direction used in musical notation. The precise meaning of tenuto is contextual: it can mean either hold the note in question its full length, or play the note slightly louder. In other words, the tenuto mark may alter either the dynamic or the duration of a note. Either way, the marking indicates that a note should receive emphasis.

Notehead elliptical part of a note

In music, a notehead is the elliptical part of a note. 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.

Sixteenth note musical note duration

In music, a 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.

Two hundred fifty-sixth note musical note duration

In music, a two hundred fifty-sixth note is a note played for ​1256 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 ≈ 80 bpm.

Maxima (music) musical note used commonly in thirteenth and fourteenth century music and occasionally until the end of the sixteenth century

A maxima, duplex longa, larga, or octuple whole note was a musical note used commonly in thirteenth and fourteenth century music and occasionally until the end of the sixteenth century. It was usually twice or, rarely, three times as long as a longa, four or six or nine times as long as a breve, and 8, 12, 18, or 27 times as long as a semibreve. Like the stem of the longa, the stem of the maxima generally pointed downwards except occasionally when it appeared on the bottom line or space. Before around 1430, the maxima was written with a solid, black body. Over the course of the fifteenth century, like most other note values, the head of the maxima became void.
