The composition was written to meet the demand of performing organists for a composition for organ and piano. This duo has a very rare instrumental composition where organ and not piano take a leading role. The form of the piece is in the middle between a sonata and a suite, with stylistic allusions to baroque concerto grosso. Despite the leading role of organ both instruments are treated evenly with their respective individual features taken into account. The coupling of organ with piano enabled the composer to produce a interesting palette of sound and colour effects.
