Belgian composer Theo Van Doren (1898 - 1974) was a Belgian composer, teacher and violinist. He was a teacher at the Music Academy of Borgerhout and was also a soloist in the orchestra of the Royal Flemish Opera in Antwerp. This edition of his Andante and Allegro for contrabass and piano was first published by Metropolis Music Publishers in 1967. The opening Andante is a chance for the soloist to demonstrate the lyrical and expressive qualities of the contrabass. Following this is the Allegro, which is a scherzo in 3/8 time, allowing the the soloist to show the technical capabilities and utilize the whole range of the instrument. The work is dedicated to Leo Van de Velde, teacher at the Royal Flemish Conservatory of Music in Antwerp.
