What is the most common form of polyrhythm?

• A. Two against Three and Three against Four
• B. One against One
• C. Four against Five
• D. Three against Five

Answer: (A)

Polyrhythm means layering two different rhythmic groupings so they share the same time span but feel like independent pulse lines. The most common cross-rhythms you’ll encounter are two against three and three against four. In two against three, three evenly spaced notes fit into the same duration as two notes, a foundational feel many musicians learn early. Three against four follows the same idea but with four notes taking the time of three; it’s another widespread pattern you’ll hear in a variety of styles. This combination is the best answer because it reflects the two forms you’re most likely to meet in real music, more than unison (one against one) or the less common 4 against 5 or 3 against 5. To feel two against three, practice clapping a steady two-beat pulse in one hand while counting three subdivided notes in the other, noting how the notes align at the start and end of the span. For three against four, count four evenly spaced notes across the same span as three and notice the alignment points.
