So I play the fiddle as well as the Anglo concertina. Now for the violin there are literally endless books of etudes and exercises which help students to work on their technique. Etudes on bowing, fingering, articulation, dynamics…you could fill a freakin’ library with them. Just look at Sevcik, Kreuter, or Flesch - really useful stuff. In my experience, mastering these challenging etudes helps overall violin/fiddle technique immensely.
But there’s nothing, to my (limited) knowledge, even remotely like that for the Anglo concertina. Until now. Calling all Anglo players, let’s make some etudes. What are the big technical challenges for concertina players (particularly intermediate-advanced ones)? What are the extremities of technique on the instrument that can be practiced to improve overall technique? What kind of exercises would you do to improve bellows technique, ornamentation, chording, finger response time, articulation, dynamics, etc? I’m not talking just "do scales", I want something that really addresses the unique technical challenges of the instrument. Post your ideas below (or links to the hidden dark web library of concertina technique literature that I haven’t found).
