Two Auloi from Megara

Abstract Two aulos pairs (Δ1965 and Δ1964), unearthed in 1980 and 2005 respectively at Megara (Attica), are exhibited in the city’s Archaeological Museum. Both are associated with metal sliding keys (resembling the keys on the well-known Pergamon aulos model), either mounted on the pipes (Δ1964) or displayed next to them (Δ1965). The present paper describes the parts, proposes a meaningful re-assemblage of the bone sections, and gives a detailed account of the sliding mechanism, which is here for the first time attested on finds of actual musical instruments, including an entirely new technology of speaker hole keys. A musical analysis, based on determining plausible reed configurations using software modelling, suggests that the finds represent a partially standardised design of professional modulating auloi, playing attested harmoníai while hovering between the enharmonic and chromatic.
