Well done Yuri! I'm a 57 year old man who, as self-taught, is trying to learn playing accordion. I'm following the Parlmer Hughes volumes and, at the moment, I'm at the first pieces of the 4th volume, I hope you will continue to produce new lessons till the level where I arrived by myself so I could procede with you (as self-taught it's ok, with a teacher even better). I appreciate as well the lesson on rythms on the bass side, for me it results quite simple play popular melodies by ear but for the bass part, when it's not polka, waltz or beguine it's always difficult to figure out a good sounding bass line.
