Close harmony is usually better heard than described. It consists of chords within a narrow range, typically within one octave. An example is Glenn Miller's "Moonlight Serenade" using the full range of single-reed wind instruments (soprano and bass clarinets, soprano, tenor, and bass saxophones) to make a distinctive sound. Other uses of close harmony include barbershop quartet and some other a cappella music.
