Musicians decided to form a traditional orchestra as described in 1844 by Berlioz in his Treatise on Instrumentation. Berlioz listed a ‘finest orchestra’ that closely approximates to the modern symphony orchestra. Such orchestra consists of 21 first violins, 20 second violins, 18 violas, 8 first cellos, 7 second cellos, 10 double basses, 4 harps, 2 piccolos, 2 flutes, 2 oboes, 1 cor anglais, 2 clarinets, 1 basset horn or bass clarinet, 4 bassoons, 4 French horns, 2 trumpets, 2 cornets, 3 trombones, 1 bass trombone, 1 tuba, 4 timpani, 1 bass drum, and a pair of cymbals (John Stanley (1994) Classical Music, Pleasantville, New York, Montreal, Reader’s Digest Association, Inc., ISBN 0-89577-606-5, p.36).
