Less is known about Ancient Roman music than is known about the music of ancient Greece. There is a number of at least partially extant sources on the music of the Greeks. For example, much is known about the theories of Pythagoras and Aristoxenus (some of it from Greek sources and some through the writings of later Roman authors), and there exist about 40 deciphered examples of Greek musical notation. Very little survives about the music of the Romans, however. There are various reasons for this, one of which is that early fathers of the Christian church were aghast at the music of theatre, festivals, and pagan religion and suppressed it once Christianity became the official religion of the Roman empire.

The Romans are not said to have been particularly creative or original when it came to music. They did not attach any spiritual ethos to music, as did the Greeks. Yet, if the Romans admired Greek music as much as they admired everything else about Greek culture, it is safe to say that Roman music was mostly monophonic (that is, single melodies with no harmony) and that the melodies were based on an elaborate system of scales (called 'modes'). The rhythm of vocal music may have followed the natural metre of the lyrics.

There were also other, non-Greek, influences on Roman culture – from the Etruscans, for example, and, with imperial expansion, from the Middle Eastern and African sections of the empire. Thus there were, no doubt, elements of Roman music that were native Latin as well as non-European; the exact nature of these elements is unclear.
