- A is a type of in which a beat (or subdivision, or multiple beats) in simple meter is divided into three parts. Notate a triplet by writing a 3 above the triplet rhythm.
- A is a tuplet in which a beat (or subdivision) in compound meter is divided into two parts. Notate a duplet by writing a 2 above the duplet rhythm.
- refers to the patterns of accentuation at the metrical level.
- happens when there are rhythmic accents, which can be created by ties, dots, rests, and/or dynamics.
Typically, a meter is defined by the presence of a consistent beat division: division by two in simple meter, and by three in compound meter. Sometimes composers will use a triple division of the beat in a simple meter, or a duple division of the beat in a compound meter; these rhythms are called . are a type of tuplet in which a beat (or subdivision, or multiple beats) in simple meter is divided into three parts. Triplets are sometimes thought of as “borrowed” from compound meter, because the beat in compound meter is usually divided into three parts. A triplet is notated by writing the number 3 on top of the triplet rhythm
Triplets may occur at both any metric level, as seen in Triplets also may occur across multiple beats, as seen in . This triplet (notated with three quarter notes) takes up the space of one half note.. In , the triplet is at the beat level—this is the most common use of a triplet. shows a sixteenth-note triplet, which is equivalent to one eighth note (the division in this time signature).
A is a tuplet in which a beat (or subdivision) in compound meter is divided into two parts. Duplets are notated by writing the number 2 on top of the duplet rhythm, as seen in.
Counting for tuplet rhythms is usually “borrowed” as well. For example, triplets are usually counted 1-la-li, while duplets are usually counted 1-and, 2-and, etc.
We have seen that beats are either accented or non-accented which was observed in the discussion of conducting patterns in the previous two chapters (see Simple Meter and Time Signatures and Compound Meter and Time Signatures). refers to groups of measures that form patterns of accentuation, especially at faster tempos. In order to label patterns of accentuation across multiple measures, it can be helpful to annotate the score with hypermetrical counts as in , which shows a reduced excerpt from the “Scherzo” of Ludwig van Beethoven’s Symphony no. 9 (1824). While listening to , try conducting along to the hypermetrical numbers in a quadruple pattern. By doing this, you will be able to feel (and hear) which measures are more accented (1 and 3) and which are less accented (2 and 4).
Syncopation happens when there are off-beat rhythmic accents (see Rhythm and Meter in Pop Music for more information), and as shows, it can be created by ties, dots, rests, and/or dynamics. In measure 1, the ties create the syncopation, while in measure 2, the rhythm is syncopated because of both a dot and a tie. The sense of syncopation in measure 3 is created by the rests at the beginning of each beat. In measure 4, while there is an eighth note on each division, the off-beat accents (dynamics) produce syncopation.

A tuplet that involves dividing a beat in simple meter into three parts.
A rhythm that involves dividing the beat into a different number of subdivisions from that usually implied by the time signature.
A tuplet that involves dividing a beat in compound meter into two parts.
Groupings of measures into different patterns of accentuation akin to meter. A hypermeasure is typically four measures long.
A rhythmic phenomenon in which the hierarchy of the underlying meter is contradicted through surface rhythms. Syncopation is usually created through accents and/or longer durations.
A rhythmic or note value that does not fall on a beat (1, 2, 3, etc.).
