Accordion patentIn 1854, the first U.S. patent for an accordion was issued to Anthony Faas of Philadephia. Pa. (No. 11,062). Faas claimed two improvements. First, he combined with the diatonic scale of the large keys two other scales, namely, one for producing all the intermediate notes, or semitones, and the other founded upon the subdominant of said diatonic scale, and both arranged so as to be fingered by a single set of small keys for the purpose of enabling the instrument to produce full and correct harmony in any key. His second improvement consisted in providing the accordion with a sound-board, for the purpose of producing more strength, fullness and resonance of tone with the instrument. |
