Further to the mondegreen, the mountweazel is also a fine creation—a bogus entry deliberately inserted in a reference work.

While I was editing the “China” entries for the New Grove dictionary of music and musicians, I tried in vain to persuade the powers-that-be that a vast civilisation with a continuous history of thousands of years might just deserve as much coverage as a composer who lived for thirty-five years (Mozart; see also here). Anyway, what with all the labrynthine complexities of the Grove style “Bible” (see e.g. here), one needs the occasional light relief (cf. the popular “composer or pasta?” quiz); and Grove now has a competition for spoof entries.

The 2016 winner was Caroline Potter:

Musical Cheesegrater
(Fr. râpe à fromage musicale; It. grattugia musicale)
A percussion instrument that enjoyed a brief vogue in Rome and Paris in the 1910s and early 1920s. In the Hornbostel-Sachs classification the instrument is reckoned as a friction idiophone. Of metal construction, it typically has four sides, each with raised perforations of a particular size. The player strokes one or more of the sides with a metal implement, producing a distinctive rasping sound. A rare rotating variant, where a perforated barrel is turned using a crankhandle to create friction against metal tangents, survives in the Musée de la Musique in Paris. The musical cheesegrater is cited in a posthumously published appendix to Luigi Russolo’s celebrated manifesto L’Arte dei rumori in the fourth category of his sound classification (screeches, creaks, rumbles, buzzes, crackles, scrapes). Its best-known use is in Maurice Ravel’s opera L’enfant et les sortilèges (1924), where it is rubbed with a triangle beater.

The musical cheesegrater was employed by Italian Futurist composers and associates of the Dada movement in Paris, and its popularity and decline mirrors the fortunes of these artistic groupings. The manuscript of Erik Satie’s Rabelais-themed Trois petites pièces montées (1919) features the instrument rubbed with a hard cheese, though scholars disagree whether Satie intended this to be a percussion instrument or part of a projected staging. Edgard Varèse showed enthusiasm for the musical cheesegrater during a dinner with Russolo; it appears in sketches for Amériques (1918-21), but not in the final version. Recent academic research in gastromusicology has revived interest in the instrument.

I’m gratified by the reference to the numinous Sachs–Hornbostel organological taxonomy, even if a whole host of stranger instruments appear there. So it’s of little consequence that just such an instrument is indeed used in several world traditions, such as the guiro/güira of merengue. Indeed, it brings to mind “our” very own washboard.

If it’s pithy organology you need, there’s also the vuvuzela. See also The shagbut, minikin, and Flemish clacket.
