hi susan,I'm just listening to it now..... you can be forgiven for thinking it is in 3/4.... because it sounds like it is. From listening to it I reckon it is in 9/8 (slip jig)time, which is 3 groups of 3 quavers in each bar...... so it can sound like 3/4. But slip jigs tend to be more lively than waltzes.
Hope that clears it up for you.
