Hello all, I'm fairly new to concertina. But have played a few other instruments, guitar, bass and Alto saxophone. So picking up one of these beautiful squeezeboxes was super strange the first couple of times. Truth be told I've had mine for around a year now and have learned a few tunes, I had ordered a Wren Anglo from Mcneela musical and it was gorgeous! It also came with a few lessons from Caitlin Nic Gabhann which were super easy to follow. I also picked up a copy of Gary's easy 1-2-3 and it's by far the easiest material to understand I've found. I guess my question has to do with me seeing alot of you all playing these beautiful old tunes, I go to check out the noteation and it's hard for me to understand, is there a specified conversion process or is it to taste, subbing In you chord preference and notes? Any insight would be appreciated, thank you!
