Hi folks I'm planning a campaign to improve my rather flaky technique on the English Concertina. Some years back I was in a workshop with Alistair Anderson where he showed us his exercise for working through a range of options for the attack, shape and finish of each note. I remember being impressed at the time but was too lazy to use it regularly. I can't find the notes I took at the time, so my memory is hazy. If anyone is able to share the details, I'd be very grateful!
