DescriptionTechnical description: Five pipes with square, leather-covered tenons, usable with chest (584a), with free reeds, (584d/1) and (584d/2,) two wooden pipes, square section, each with a wooden cap with a circular aperture, each with a single free reed. (584d/3,) (584d/4) and (584d/5,) three wooden pipes, square section, each with a hinged top section to allow access to reeds, each with four free reeds mounted in separate reed plates each with and four sliders. (584d/3) only stamped "VON / C. APPUNN / & / SÖHNE" inside belt with "AKUSTISCHE APPARATE / IN HANAU". Stamped on respective reed plates, 585d/1 "ut"; (584d/3) "C", "E", "G", "C"; (584d/4) "B", "E", "G", "B"; (584d/5) "C", "E", "G", "C". Scratched beneath respective sliders in older script, (584d/3) "C", "E", "G", "C"; (584d/4) "C", "E", "G", "C"; (584d/5) "C", "E", "G", "C". Scratched beneath respective sliders in newer script, (584d/3) "C", "E", "G", "C" and "Highest note"; (584d/4) "B", "E", "G", "B"; (584d/5) "C", "E", "G", "C". Repair History: Reed of (584d/2) missing; top section of (584d/5) missing; knob missing from one slider of (584d/3). Usable pitch: (584d/1) sounds respectively 63.5 Hz; (584d/3) sounds respectively 256 Hz, 320 Hz, 385 Hz, 513 Hz; (584d/4) sounds respectively 63.5 Hz, 70.5 Hz, 95.5 Hz, 128.5 Hz; (584d/5) sounds respectively 257 Hz, 160 Hz, 191 Hz, 255 Hz. Formerly used with pipe chest (584a) but possibly originally with another chest with bellows. |
Other InformationGeneral usage of type: Using one of the longer single-reed pipes to produce a fundamental together with an appropriate shorter multiple-reed pipe to produce notes at the frequencies of the first four harmonic overtones, different tone qualities can be produced by adjusting the sliders to control the sound volume from each reed. Specific usage history: Formerly used in the Laboratory of Experimental Psychology, University of Glasgow. |
