harmonica

Other names: ハーモニカ

The harmonica, also French harp, blues harp, and mouth organ, is a free reed wind instrument used worldwide in nearly every musical genre, notably in blues, American folk music, jazz, country, and rock and roll. There are many types of harmonica, including diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth (lips and/or tongue) to direct air into and out of one or more holes along a mouthpiece.
