La Concertina Method for Concertina Instruction Book.
La Concertina Method for Concertina Instruction Book. The diatonic concertina is a popular instrument used in folk music. While a chromatic concertina sounds the same note when opening and closing the bellows, a diatonic instrument sounds a different note upon opening and closing of the bellows. The two-note-per-button system allows for numerous interesting variations, and the instrument is a great tool for composition due to its ease of use. This Italian book is mostly written in G major but the pieces can be adapted to differently tuned instruments because the button layout is always the same.
