Music was a major part of everyday life.[citation needed] The word itself derives from Greek μουσική (mousike), "(art) of the Muses". Many private and public events were accompanied by music, ranging from nightly dining to military parades and manoeuvres. In a discussion of any ancient music, however, non-specialists and even many musicians have to be reminded that much of what makes our modern music familiar to us is the result of developments only within the last 1,000 years; thus, our ideas of melody, scales, harmony, and even the instruments we use may not have been familiar to Romans who made and listened to music many centuries earlier.[citation needed]
