An aria (; ; plural: arie , or arias in common usage, diminutive form arietta ) in music was originally any expressive melody, usually, but not always, performed by a singer. The term became used almost exclusively to describe a self-contained piece for one voice, with or without orchestral accompaniment, normally part of a larger work. The typical context for arias is opera, but vocal arias also feature in oratorios and cantatas, sharing features of the operatic arias of their periods.

The Australian Recording Industry Association (ARIA) is a trade group representing the Australian recording industry which was established in 1983 by six major record companies, EMI, Festival, CBS, RCA, WEA and Universal replacing the Association of Australian Record Manufacturers (AARM) which was formed in 1956. It oversees the collection, administration and distribution of music licenses and royalties.
