text: The term can also refer to the use of a double orchestral body where a work is in concerto grosso form; for example, Martinů's Double Concerto for Two String Orchestras, Piano, and Timpani is commonly known by the title "Double Concerto," where the word "double" refers to the two string bodies rather than to the piano and timpani, who are not soloists in the conventional sense.
