The are in the book songs without text. Check out samples from books: http://osos.sweb.cz/Preview-Anglo-concertina.pdf This book features 16 songs. The diatonic accordion managed to spread worldwide as well as Jewish music before. Moreover, Jewish music achieved to absorb different folk music, mostly European. For the reason you can meet here with beautiful melodies in minor, which are not scales preferred by diatonic accordion playing. Much joy in the disovery of Jewish songs.
