It was premiered by the English composer and pianist Elizabeth Poston.
The first theme is shared between cellos and violins on its return, with the harpsichord playing accompanying arpeggios.
The last movement is in 6/8 and abounds in cross-rhythms; a number of short themes succeed each other rapidly.
A short cadenza leads to a reprise incorporating themes from all three of the movements.
It has been recorded by Trevor Pinnock on Lyrita; George Malcolm on BBC radio classics; Colin Tilney on CBC; Neville Dilkes on EMI; Anna Paradiso on Barn Cottage Records (2012).
