"Sweet singing in the choi/r/": How spoken dialect affects choral phonology in Glasgow and Cambridge

British classical choirs are thought to use a prestige accent when singing in English.In Scotland there are two available prestige accents, local (SSE), and supralocal (SSBE).Does local consonant phonology affect choral phonology?Here, I investigate regional accent effects in a real-time study of choral singing in commercially released recordings of choirs from Glasgow and Cambridge.Postvocalic /r/ is auditorily coded and analyzed using Bayesian models.Rhoticity is widespread in Glasgow reflecting the phonology of Scottish varieties; however, it declines over time, perhaps reflecting change to an SSBE referee, or the impact of the choir director's accent or preferences.
