If you're playing folk music a good way is to start with double jigs
You can count to 6, but do it to the beat of 'Liverpool, Everton -
Liverpool, Everton - Liverpool, Everton ...'
Take care if you come across slip jigs which are in 9. That would
be Liverpool Everton Everton, Liverpool Everton Everton.
Listen to tunes before playing and it will start to make sense.
