Hot Metal Harmonica. Key of BF. For 150 years and counting, Hohner's diatonic harmonicas set the industry standard through high quality construction, excellent response an unsurpassed tone. Often called Blues Harps, they remain a fixture as both melody and accompaniment instruments in blues, rock, country and folk bands, as well as many other styles of music and musical ensembles. Richter tuning and undivided air channels allow for bending and overblowing reeds, creating the signature wailing sound typical of the harmonica.
