What is a 3 against 2 polyrhythm?
3:2 polyrhythm: Known as hemiola, this triple-over-duple polyrhythm involves a three-note rhythm held over a two-note rhythmic pattern. Typically, this involves triplets over quarter notes or eighth notes.
What is the rhythm of polyrhythm?
polyrhythm, also called Cross-rhythm, the simultaneous combination of contrasting rhythms in a musical composition. Rhythmic conflicts, or cross-rhythms, may occur within a single metre (e.g., two eighth notes against triplet eighths) or may be reinforced by simultaneous combinations of conflicting metres.
What is a famous example of a hemiola?
Three beats in every bar the hamiola trick is this i put a note in that takes up beats one and two then i put a note in that takes up beats three and one.
What is an ostinato in music?

Are triplets polyrhythms?
Quarter note triplets over 8th notes would be a 3:4 polyrhythm. Quarter note triplets over quarter notes would be 3:2. The formula is how many times the rhythms happen in the same span. 3 triplet quarter notes take the same amount of time as 2 quarter notes or 4 eighth notes.
What are Polymeters?
A polymeter is where two sequences are played using different meters, but with the same tempo. For example a pattern that repeats a sequence over 5/4 played against one repeating over 4/4 (figure 3). After 20 pulses the original patterns will repeat again (the lowest common denominator of two time signatures).
What is the difference between syncopation and hemiola?
Hemiola is where a 2 beat rhythm is played over a 3 beat bar. It is a specific type of polyrhythm. Syncopation is an intended disturbance of the regular flow of the rhythm, usually by playing an off-beat note.
What is a triplet note?
In music theory, a triplet is a three-note pattern that fills the duration of a typical two-note pattern. Each note in a triplet has equal rhythmic value.
What is a duplet in music?
A duplet – a type of tuplet – is a note-grouping of two, which fits into the length of three of its note-type. For example: Eighth-note duplets span the length of three normal (or “straight”) eighth-notes. Sixteenth-note duplets span the length of three 16th notes (or a dotted eighth-note).
How do you name triplets music?

nine. A tuplet may be represented with a number in three ways. A number within a bracket helps to identify tuplet groupings that are not beamed. Such notes are anything greater or equal in value than a quarter note. A slurred tuplet identifies a group of notes to be played legato.
What is a quadruplet music?
According to Jon Peckman, in drumming, “quadruplet” refers to one group of three sixteenth-note triplets “with an extra [non-tuplet eighth] note added on to the end”, thus filling one beat in 4. 4. time, with four notes of unequal value.
