Thank you Jerry for showing us The Complete Technique Book for the Piano Accordion, no doubt it will be an indispensable resource for anyone seeking to understand the foundations of MIII technique. Good share!
By the way, I received another book through the post last week. It's a selection of 12 "easy pieces" by Beethoven, adapted for accordion by Ivano Battiston. Again, as it's an Italian publication, the book is dual system: written with piano accordion and button accordion (C system) in mind and with fingering for both system. Also the free bass system of 5ths (Quint) and system of minor thirds (chromatic - C griff) are fingered.
I have some more special music on its way, that I hope to share it in due course. There is a world of wonderful music out there prepared especially for us by some truly gifted and dedicated musicians.
