found: Grove music online, March 8, 2021:Concerto (An instrumental work that maintains contrast between an orchestral ensemble and a smaller group or a solo instrument, or among various groups of an undivided orchestra. Before 1700 the term was applied to pieces in a variety of forms for an even greater variety of performing media, voices as well as instruments; it was also used in the sense of 'ensemble' or 'orchestra'.)

found: Grove music online, March 8, 2021:Symphonie concertante (A concert genre of the late 18th and early 19th centuries for solo instruments--usually two, three or four, but on occasion as many as seven or even nine--with orchestra; Attempts at explicating the term 'symphonie concertante' have foundered on two counts: first, on the confusion between the adjective 'concertante', loosely employed in the 18th century, and the noun-complex 'symphonie concertante', which refers to a specific genre; and secondly, on the difference between works called 'symphonie concertante' and those, also with more than one solo instrument, called 'concerto for two [three, four] instruments')
