I'm restoring my first Bandoneon .... a pre-war instrument in marvelous condition (needs very little work). I'm also attempting to teach my self to play. I'm a woodwind musician and a Tanguero, both of which hep, but as Astor P. said, "you must be a little 'out of your mind' to want to learn to play this instrument." Any advice or references are very welcome. (My Spanish is moderate but manageable.)
