This three-movement concerto in G is the best known of the seven double bass concertos by Franz Keyper (1756-1815) thanks to its rondo finale. All demonstrate a unique virtuoso style and, unusually for the classical period, were written for an instrument tuned in fourths. Keyper’s mastery of the instrument and composing for it developed through the concertos, and I Musicanti Publishing are making all seven available, in editions prepared by Leon Bosch.
