Aura

Aura (Lat.: breath), 1. name of an early *mouth organ patented by Friedrich Buschmann of Berlin in 1821; 2. device invented by Johann Heinrich Scheibler of Krefeld in 1816, by which 3, 4, or 5 Jew's-harps of different pitches could be combined in a frame, thus permitting rapid change of tonality. He seems to have combined subsequently a larger number of tongues in one frame (15, 117). Sort by:DefaultTitleDateAuthorAscendingDescending Baines, Anthony, editor. Musical Instruments Through the…
