The De Haske String Orchestra Series offers attractive pieces especially composed and arranged for string orchestras. Students and teachers are treated to a great variety of musical styles. Each part presents a challenge to the player. The Viola part can be replaced by a 3rd Violin part, and the Double bass part can be replaced by a 2nd Cello part. The Piano part is mainly meant for support, but it occasionally adds new motifs as well.

In Folk Express, the string orchestra travels the world in a tearing rush: from Ireland (Slippery Road Jig) to the USA (Paradise Polka), followed by a sudden landing in the heart of the Balkan (Heading East fromBelgrado).
