An orchestra group is composed of a variety of instruments, including oboes (5 letters), reeds (5 letters), HORNS (5 letters), strings (7 letters), and violas (6 letters). Oboes are woodwind instruments that produce a mellow sound. Reeds are also woodwind instruments, but they produce a more piercing sound. HORNS are brass instruments that produce a loud, brassy sound. Strings are string instruments, such as violins, cellos, and double basses, that produce a softer sound. Violas are string instruments that are slightly larger than violins and produce a deeper sound. Together, these instruments create a full, rich sound that is characteristic of an orchestra group.
