From the tenth through the twelfth centuries some manuscripts containing Virgil’s poems contain the musical notation known as neumes. Thereafter such notation of Virgil apparently ceases for centuries. The neumes (and singing) may have fallen by the wayside as new practices developed of singing Latin rhythmic poems or vernacular songs based on Virgil, rather than excerpts from Virgil’s own quantitative poetry. In prefaces to the Paraclete Hymnbook Peter Abelard quotes observations by Heloise on the need for a more regular syllable count than in quantitative hymns. Virgilian reception and musical notation may have evolved together away from quantitative Latin.
