Boismortier is considered to be one of the most popular and most hard-working composers of his time. The original title of this sonata in A Minor indicates flutes, violins and other instruments as well suited for performance. The composer arranged the first melody part in such a way that it can be played by an alto recorder without any changes. Scored for string chorus, the sonata achieves a very good tonal effect. With soloistic scoring, three equal instruments (e.g. three violins) or three completely different instruments (e.g. flute, violin, oboe) are best suited for the performance of the upper parts.
