Harmonikka is the Finnish accordion tradition and repertoire, centered on solo and ensemble playing of chromatic and diatonic button accordions in Finland. It foregrounds dance-derived forms such as waltz (valssi), jenkka (Finnish schottische), polkka (polka), humppa, mazurka, and the distinctly Finnish tango. Stylistically, the music features a singing right-hand melody embellished with grace notes, turns, and bellows shakes, and a left-hand oom‑pah (bass–chord) accompaniment with crisp staccato and tightly controlled bellows phrasing. Timbres range from dry, focused reeds to lightly tremolo “wet” tunings; players use register switches to shape color from intimate chamber tones to bright festival projection. Though often purely instrumental, harmonikka also supports popular Finnish schlager (iskelmä) songs and social dance contexts.
