It's important to understand what is meant by '32 bar jigs', '48 bar reels', etc., and why it is significant!

Whilst there are some 48 bar tunes (usually AA BB CC), any 32 bar can be adapted either by AB AB AB (tedious!), or AA BB AB (challenging!).

Watching the dancers' feet is paramount!

When playing for beginners/intermediates, a good solid 'tick tock' accompaniment is far more useful than clever tricks. Playing for an audience is very different from playing for dancers.

Bass players and drummers are the worst culprits...! ;o)

Whilst I'm up here on my high horse, the 'modern trend' for playing a tune until the band gets fed up then playing another tune is not very helpful to the dancers - or the caller. Yes, I know playing one tune is often appropriate for Morris (I'm a Morris musician, too), but 'social dancing' is different.

Playing one tune for the first set of figures, and a different tune for the second time through, reverting to the first tune for the third time (etc.) takes more thinking, but is far more structured. I played in a dance band from the early 1970s until around 1990, and that was what we usually did - unless a specific dance had different requirements. Unfortunately, the tendency these days is to dance despite  the music, rather than be guided by it. All too often the band is back to the start of the tune but the dancers haven't completed the set of figures, so everything is out of sync...

We used to start and end on a chord, too (Scottish dancing style) - all too often the 'introduction' is so vague that not even the caller knows when the dance has started.

Nowadays I only play occasionally when a band needs a temporary musician (I play accordion, guitar or bass as required).
