From June Carter Cash to The Rolling Stones, the autoharp can be found in a wide spectrum of musical genres, but it is predominate in American folk music. With origins in Germany and popularized in the United States in the late 19th century, the autoharp is a box zither with 15 to 50 plus strings. Modern autoharps typically have 36 or 37 strings. Oscar Schmidt has been a leading autoharp manufacturer since the early 1900s, the company also provides quality strings for autoharp that complement both rhythmic chordal accompaniment and produce bright melodies. Oscar Schmidt’s strings for autoharp are available in two versions: model A with an eyelet end and model B with a ball end. The model A autoharp strings are designed for traditional autoharps built before 1967, and the model B set is for modern autoharps built after 1967. To easily differentiate between the two models, check the tuning pins. The tuning pins of pre-1967 autoharps are set at a slant, meaning you require model A. Producing a bright, crisp tone with great response, both sets of strings for autoharp feature 36 strings and fit 12 to 15 bar autoharps.
