Based on the piece Double Trio (1938), the composer decided its music would be better-suited to a larger instrumentation. He fashioned the piece for two string orchestras of disproportionate size, neither featuring second violins.
The Partita is comprised of four movements: 1.Prelude: Andante tranquilo, 2.Scherzo ostinato. Presto , 3.Intermezzo: Andante con moto, 4.Fantasia: Allegro.
The piece should have wide appeal, especially to fanciers of music for string ensembles.
