text: Concertos with more than two solo parts may be known by the terms "triple concerto", "quadruple concerto", etc., but not usually when the instruments are of the same type (for example, Vivaldi's Concerto for Four Violins in B minor, catalogued as RV 580 and transcribed for four harpsichords by Bach as BWV 1065).
