What are symmetrical meters?
Symmetrical meters are meter types created by recurring, regularly spaced patterns of accent on the different levels of pulse, including division, beat, and measure.
Define syncopation.
Syncopation is a rhythmic device that occurs when rhythm places an accent on weak beats or divisions of the beat.
What is a cross-rhythm (or polyrhythm)?
A cross-rhythm is the simultaneous occurrence of two or more rhythmic patterns that do not derive from one another and are not rooted in the same meter.
A measure with a time signature of (5/8) is an example of what kind of metrical irregularity?
This is an example of changing or mixed meter because it contains beats of unequal size.
In what two formats must you be able to identify rhythmic devices?
You must be able to identify rhythmic devices in both performed music (aural) and notated music (visual).
What fundamental characteristic is challenged by changing or mixed meters?
Changing or mixed meters challenge the idea that meters must be regularly periodic at all levels of pulse.
What is the primary effect of rhythmic devices like syncopation?
Rhythmic devices like syncopation enliven music by challenging the regularity of an established meter.
If you hear a strong accent on beat 2 in a waltz (3/4 time), what rhythmic device is likely being used?
This is an example of syncopation, as an accent is placed on a weak beat (beat 2) instead of the strong beat 1.
Define changing or mixed meter.
Changing or mixed meter occurs when meters are not regularly periodic at all levels of pulse, such as in a 5/8 measure which contains beats of unequal size.
What distinguishes a cross-rhythm from other complex rhythms?
In a cross-rhythm, the simultaneous rhythmic patterns are not derived from one another and are not rooted in the same meter.
