Petar Ralchev's book Balkan Accordion extends the instrument's rhythmic, tonal and harmonic spectrum. It contains a diverse range of well-known instrumental pieces, songs and dances with a distinct Eastern European flavour and with catchy melodies and rich ornamentation. For each piece the author has written a short introduction on its background and characteristics. The pieces are intermediate level and the notation is clear and easy to read. / Accordéon
