A hemiola is a musical pattern where a passage written in a time signature with a triple feel, such as 3/4 time, is interpreted or played with the accent pattern of a duple time, such as 2/4 time. In Baroque music, composers would often use a hemiola when approaching a cadence to vary the rhythm. For example, in Handel's "And the Glory of the Lord", a hemiola can be heard in bars 9-10 of the introduction where the chords change every two beats, despite the 3/4 time signature.
