Acoustically, unaccented beats are typically played at a lower volume or with a less forceful attack than accented beats. This can be achieved by playing the note less loudly, using a softer touch on the instrument, or playing the note with a shorter duration.
Visually, unaccented beats are often notated with smaller note heads or stems than accented beats. This helps to indicate that these beats are less important in the rhythmic structure of the music.
Examples of unaccented beats include the second and fourth beats of a four-beat measure, or the second and third beats of a three-beat measure. In some musical styles, such as jazz and funk, unaccented beats may be played with syncopated rhythms or improvised variations, adding complexity and interest to the music.
