Accent (music)

The horizontal wedges on four of the sixteenth notes are accents. They instruct the musician to play those notes more forcefully.

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 their interpretation of a musical piece.

Compared to surrounding notes:

• A dynamic accent or stress accent is an emphasis using louder sound or stronger sound; typically most pronounced on the attack of the sound.
• A tonic accent is an emphasis on notes by virtue of them being higher in pitch, as opposed to higher in volume.^[1]
• An agogic accent is an emphasis by virtue of notes being longer in duration.

Accents that don't correspond to the stressed beats of the prevailing meter are said to be syncopated. For example, in common time, also called 4/4, the most common metre in popular music, the stressed beats are one and three. If accented chords or notes are played on beats two or four, that creates syncopation, since the music is emphasizing the "weak" beats of the bar. Syncopation is used in classical music, popular music, and traditional music. However, it is more prominent in blues, jazz, funk, disco, and Latin music.
