15 simple melodies represent each of 14 instruments of the orchestra which have pipe organ equivalents: violin, viola, cello, string bass, flute, oboe, English horn, bassoon, clarinet, trumpet, trombone, tuba, horn or French Horn, and timpani, as well as The Principal Chorus. The melodies and one-sentence texts for each sound may be copied from the score and distributed to upper elementary school students who will listen to the tunes played on the organ, then sing them.
