Portuguese CBA Tutor books?

[Ganza]

Hi

does anyone know of any Portuguese C-system CBA tutor books? Or where I might buy one?

I know the Portuguese almost exclusively use the 3+3 bass layout (also common, at least in the past, in France).

My accordion has the 3+3 layout and, whilst my Basseli-Astier tutor books cover utilise this bass system, I'm keen to find as many resources on it as I can, because I think it could possibly be used as a QUASI-free bass system?


Thanks

Maybe you could contact Spanish accordion teacher Gorka Hermosa ?

He has written about accordion in Spain, there are some documents for download in the musicology section on his website:

Maybe he knows of a Portugese CBA tutor? Or he could get you in contact with Portugese accordion teachers.

Or Paulo Jorge Ferreira from Portugal ?
