Garmon
The garmon (Russian: гармо́нь, IPA: [gɐˈrmonʲ], from Russian: гармо́ника, romanized: garmonika, IPA: [gɐˈrmonʲɪkə], cognate of English harmonica), commonly called garmoshka, is a kind of Russian button accordion, a free-reed wind instrument. A garmon has two rows of buttons on the right side, which play the notes of a diatonic scale, and at least two rows of buttons on the left side, which play the primary chords in the key of the instrument as well as its relative harmonic minor key.
