Moore (2012) is a thorough discussion of music in Roman comedy. For musical structure, see also Moore (1998a) and Marshall (2006). Gratwick (1982a) and Moore (1999) review the connections between music and character. Moore (2007) discusses music in Terence. For the connection between metre and musical accompaniment, see Moore (2008). Questa (2007) is the best introduction to Roman comedy’s metres. Those with no Italian will do best to start with the sections on metre in Gratwick (1993) and (1999) and Barsby (1999). Questa (1995) has scanned, and Braun (1970) has analysed, Plautus’ polymetric songs. For identification of metres in the rest of Roman comedy, the schemata metrorum in the texts of Lindsay (1904–5) and Kauer and Lindsay (1958) are invaluable. Lindsay (1922), though dated, is still useful, as is the chapter on music in Beare (1964). For singing in the ancient theatre, see Hall (2002). Wille (1967) is an encyclopedic compilation of evidence for music in the Roman world. Moore (2016) is an online database of all the metrical changes in the extant plays of Plautus and Terence.
