Guest MCP - we agree in principle; translate from 3/4 to 6/8 and you get the same result.

There is no universal agreement as to the use of the term hemiola, save for its referring to a ratio of 3:2. Collins Encyclopaedia of Music gives a rhythmic example by Chopin (Etude # 27) where the left hand plays in 2/4 and the right hand plays in 3/4. Encarta says: "hemiola, or the simultaneous or sequential juxtaposition of duple and triple rhythmic figures". So your example (and mine) are sequential; Chopin's use is simultaneous
