Ee [Abbreviations] e
In the timing of dance steps and actions, an "e" (like the "a") also represents 1/4 beat. It is not much used in round dancing, but I'll include it here just for completeness. Where the "a" represents the fourth quarter of a beat, the "e" represents the second quarter. The last two beats of a measure might then be segmented into a 3 - e - & - a, 4 - e - & - a; and then we could talk about stepping on or holding any of these little quarter-beat moments. The timing of one Cha measure is commonly thought of as 123&4. With added precision, we might explain that we dance the cha-cha-cha by stepping on the 3, holding the e, stepping on the &, holding the a, stepping on the 4, and then holding the e, &, and the a of that last beat. (Whew!)
