What time signature would typically utilize Horizontal Hemiola?

Horizontal hemiola refers to a rhythmic concept where two groups of three beats (often seen in 6/8 or 3/4 time) interact with three groups of two beats, creating a cross-rhythmic texture. In this context, a time signature of 6/4 is particularly suited for this type of hemiola because it consists of two measures of a simple 3/4 meter played simultaneously. The first three beats can be interpreted as one rhythmic unit while the second three beats provide a contrasting pulse, making it ideal for creating the effect of horizontal hemiola.

Additionally, 6/4 allows for both a strong sense of the underlying six beats and the superimposition of a three-beat feel, seamlessly creating that interplay typical of hemiolic structures. In contrast, the other time signatures listed—4/4, 3/4, and 5/4—do not accommodate this rhythmic interaction in the same way and lack the specific groupings that allow for effective execution of horizontal hemiola.
