Etymology

Origin of harmonica

Noun use of feminine of Latin harmonicus harmonic; in the form armonica (< Italian < Latin ) applied by Benjamin Franklin in 1762 to a set of musical glasses; later used of other instruments

Explanation

A harmonica is a musical instrument that's small enough to fit in your pocket. Harmonicas are especially popular in blues bands. Harmonicas have between 10 and 16 small holes, each with a small reed behind it. Players blow through one or more of the holes, changing the sound by pulling air at times instead, altering the shape and tension of the mouth, and by opening and closing their hands around the harmonica. Using these methods, great harmonica players can extract beautiful, complex sounds from this tiny instrument. The Greek root of harmonica is harmonikos, "musical."
