IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

A hemiola is a temporary shift in accent that makes two groups of three feel like three groups of two, or vice versa.

Detailed Definition
Hemiola destabilizes a listener’s sense of meter by recasting the same duration through a different pattern of emphasis. In poetry, it can describe a rhythmic moment when stresses reorganize the expected beat, making a line lilt, stumble, dance, or resist regular scansion. Poets may use this effect to mark emotional change, intensify a refrain, or make a familiar form feel newly unstable without abandoning its underlying structure.
Example
Example in poetry:
Hemiola is a rhythmic shift that makes two groups of three beats feel like three groups of two, and a poet can suggest it by alternating “ONE two three, ONE two three” with “ONE two, THREE four, FIVE six”; A line of six syllables can be reaccented from three pairs into two triplets; The phrase “falling leaves / across the road” can shift between paired and triple stresses; Hemiola can make a poem’s dance rhythm suddenly feel unstable or transformed.
Additional Notes
A hemiola changes the perceived grouping of beats, commonly making two groups of three sound like three groups of two. The total duration stays the same, but accents shift, producing a temporary change in rhythmic perspective. In poetry, a similar effect can arise when stresses reorganize across a line or when phrasing cuts against the expected meter. Hemiola is especially useful for describing rhythmic surprise, tension, or a dance-like lilt. It relates to syncopation and polyrhythm.
