- Accent (music)
In music, an accent is an emphasis placed on a particular note, 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. Compared to surrounding notes:
- A dynamic accent or stress accent is an emphasis using louder sound, typically most pronounced on the attack of the sound.
- A tonic accent is an emphasis on a note by virtue of being higher in pitch.
- An agogic accent is an emphasis by virtue of being longer in duration.
There are four kinds of agogic accent:
- Longer notated duration of a note, for example, a half note among quarter notes.
- Extended duration of a note within its full time value (without altering the tempo). For example, players of organ and harpsichord (which don't afford the use of dynamic accents) can emphasize one of a sequence of staccato quarter notes by making it less staccato.
- Extended duration of a note with the effect of temporarily slowing down the tempo.
- Delayed onset of a note.
In music notation, an accent mark indicates a louder dynamic to apply to a single note or an articulation mark. The most common is the horizontal accent, the fourth symbol in the diagram above; this is the symbol that most musicians mean when they say accent mark. The vertical accent, third in the diagram, may be stronger or weaker than the horizontal accent; composers have never been consistent in using these markings. In most musical works this type of accent is meant to be played more forcefully and usually shorter. The remaining marks typically shorten a note.
- Staccato, the first symbol shown above, indicates that the last part of a note should be silenced to create separation between it and the following note. The duration of a staccato note may be about half as long as the note value would indicate, although the tempo and performers' taste varies this quite a bit.
- The staccatissimo, shown second, is usually interpreted as shorter than the staccato, but composers up to the time of Mozart used these symbols interchangeably. A staccatissimo quarter note would be correctly played in traditional art music as a lightly articulated sixteenth note followed by rests which fill the remainder of the beat.
- The marcato, shown third, the vertical open wedge, is even louder or more marked than a regular accent mark.
- The fourth mark shown, the Accent mark, indicates that the marked note should have an emphasized beginning and then taper off rather quickly. This mark is correctly known by classically trained musicians as marcato, though it is usually simply referred to as an accent.
- The tenuto mark, shown fifth above, has three meanings. It may indicate that a note or chord is to be played at full length or longer; it may indicate that a note or chord is to be played a bit louder; or it may indicate that a note is to be separated with a little space from surrounding notes. The last meaning is usually inferred with there are several notes with tenuto marks in a row, especially under a slur. Tenuto is Italian for "sustained".
Even when these symbols are absent, experienced musicians will introduce the appropriate gesture according to the style of the music.
Percussion music in particular makes use as well of anti-accent marks, notated as follows:
- slightly softer than surrounding notes: u (breve)
- significantly softer than surrounding notes: ( ) (note head in parentheses)
- much softer than surrounding notes: [ ] (note head in brackets)
