When I created the MIDI files for the Lewes Favourites, I didn't really give it much thought and now wish I had. All the tunes are just once through and probably at the default tempo of crotchet=120.

Recently, for tune sets for our Spare Parts workshops at festivals I have done versions that play the tunes several times at default speed and half speed.

I'm not sure if I'll get round to re-doing the Lewes Favourites that way. It's rather labour intensive.

Of course, because they are computer generated, they are rather mechanical and not very musical.
