# Glossary
Listed below are technicial terms and musical terms, which are frequently used in MuseScore or in the Handbook. Links to relevant handbook chapter are provided. To help musicians who are capable of reading a notation but do not know its proper name, image is provided. This chapter does not aim to be a dictionary of all musical notations, see External links.
The differences between American English and British English are marked with "(AE)" and "(BE)", respectively. Editors and translators of this chapter should add the individual entry for each term.
### A
* Acciaccatura
A short grace note which appears as a small note with a stroke through the stem. Musescore creates a quick playback, the playback duration is not affected by duration of the parent note.
* Accidental
An accidental is a sign appearing in front of a note that raises or lowers its pitch. See Entering notes and rests:Accidentals. chapter. Musescore creates playback for common accidentals only, they includes sharps, flats, naturals, double sharps, double flats, and triple flats. To create microtonal accidentals such as quarter tone, see Tuning systems, microtonal notation system, and playback Chapter.
* Ambitus
Note (or vocal) range used in a staff. Used particularly in early music. See Ambitus chapter.
* Anacrusis (mostly BE)
See [Pickup measure](#pickup-measure).
* Anchor
The point of attachment to the score of objects such as Text and Lines: When the object is dragged, the anchor appears as small brown circle connected to the object by a dotted line. Depending on the object selected, its anchor may be attached to either (a) a note (e.g. fingering), (b) a staff line (e.g. staff text), or (c) a barline (e.g. repeats).
* Appoggiatura
A long grace note which takes value from its associated note. Musescore creates playback as such. It is acceptable to execute written appoggiatura as acciaccatura nowadays but Musescore does not create such playback. Appoggiatura's functions include: passing tone, anticipation, struck suspension, and escape tone.\\
* Arpeggio
An **arpeggio** tells the performer to break up the chord into the constituent notes, playing them separately and one after the other. The arrow arpeggio symbol indicates the direction in which the player should play the notes of the chord. See Arpeggios and glissandi chapter.\\
* Articulation
A marking or symbol indicating how a note should be played, usually by altering the length of a note or shaping its attack and decay. See Articulation chapter.

* Bar (BE)
See measure.
* Barline
Vertical line through a staff, staves, or a full system that separates measures. See Barline chapter.

* 2\. In some chapters of the MuseScore Handbook, **score** means the layout and formatting of "Full score" or one particular Musescore part. See Musescore Part.
* 3\. In other contexts (for example the IMSLP score-sharing website at ), a score generally refers either to a PDF file of the sheet music for a specific work or to an actual paper copy of the sheet music.
* Section
In MuseScore, a region of the score between section breaks; also from the start of a score to the first section break, and from the last section break to the end of the score.
* Segno
A navigation marker. See Jumps and markers chapter.
* Semibreve (BE)
A **whole note** (AE). It lasts a whole measure in 4/4 time.
* Semiquaver (BE)
A sixteenth note.
* Semihemidemisemiquaver (Quasihemidemisemiquaver) (BE)
A hundred and twenty eighth note.
* Sextuplet
See tuplet.
* SF2
A virtual instrument format developed by E-mu Systems and Creative Labs. See SoundFonts.
* SF3
An invention of Werner Schweer, the Musescore developer (source). This format supports sound sample compression. See SoundFonts.
* Shared note head
A single notehead with two beams—one up, one down. Especially common in guitar music, for example. See Noteheads
* Sharp
Sign (♯) that indicates that the pitch of a note has to be raised one semitone , see accidentals and key signature.
* Slash (slash chord, slash notehead)
Indicates strum. See Slash chord (Wikipedia).
* Slash notation
A form of music notation using slash marks placed on or above/below the staff to indicate the rhythm of an accompaniment: often found in association with chord symbols. There are two types: (1) *Slash notation* consists of a rhythm slash on each beat: the exact interpretation is left to the player (see Fill with slashes); (2) *Rhythmic slash notation* indicates the precise rhythm for the accompaniment (see Toggle rhythmic slash notation).
* Slur
A curved line over or under two or more notes, meaning that the notes will be played smooth and connected (*legato*). See Slur chapter. A slur is not a tie.
* Solmisation
see Endecalineo
* SoundFont
A virtual instrument format supported by MuseScore. A **SoundFont** is a special type of file (extension .sf2, or .sf3 if compressed) containing sound samples of one or more musical instruments. In effect, a virtual synthesizer which acts as a sound source for MIDI files. MuseScore 4 comes with its own native soundfont, *MS Basic*. See SoundFont chapter.
* Spatium (plural: Spatia) / Space / Staff Space / sp. (abbr./unit)
A unit of measurement, see Page layout concepts.
* Stave / Staves

### T
* Text
A Musescore Text object is an object that contains individual characters that can be entered and removed by using (typing on) a computer keyboard. See Entering and editing text chapter.
* Tie
A curved line between two adjacent notes of the same pitch to indicate a single note of combined duration. See Tie chapter. A tie is not a slur.
* Quarter note + Tie + Quarter note = Half note
* Quarter note + Tie + Eighth note = Dotted Quarter note
* Quarter note + Tie + Eighth note + Tie + 16th note = Double Dotted Quarter note
* Transposition
The act of moving the pitches of one or more notes up or down by a constant interval. See Transposition chapter. There may be several reasons for transposing a piece, for example:
1. The tune is too low or too high for a singer. In this case the whole orchestra will have to be transposed as well—easily done using MuseScore.
2. The part is written for a particular instrument but needs to be played by a different one.
3. The score is written for an orchestra and you want to hear what the individual instruments sound like. This requires changing the transposing instrument parts to concert pitch.
4. A darker or a more brilliant sound is desired.
* Triplet
See tuplet.
* Tuplet
A tuplet divides its next higher note value by a number of notes other than given by the time signature. See Tuplet chapter. For example a triplet divides the next higher note value into three parts, rather than two. Tuplets may be: triplets, duplets, quintuplets, and other.
### U
* Upbeat
See [pickup measure](#pickup-measure).
### V
* Velocity
A property of objects inside Musescore that controls how loudly note(s) are played, see musescore 3 handbook Loudness of a note chapter. Velocity property of notes are edited using **Properties panel: Playback tab**, see Properties panel chapter.
* Voice
* 1\. In Musescore, voice is a software feature, you can use up to 4 voices per staff, see Working with multiple voices, also see staff.
* 2\. The musical term "voice" refers to a musical line or part which can have its own rhythm. MuseScore does not have a feature to implement the exact same idea, if the voice feature does not suit your need, try adding separate instruments instead.
* Volta
In a repeated section of music, it is common for the last few measures of the section to differ. Markings called voltas are used to indicate how the section is to be ended each time. These markings are often referred to simply as endings. See Volta chapter.
### W
* Written pitch
Transposing instruments (such as the clarinet, French horn, trumpet etc.) are notated at a different pitch (and key signature) to how they sound. The notated pitch is called the written pitch. Contrast with concert pitch. See Staff / Part properties chapter.
