Editing Duet (section)

== History ==
When [[Wolfgang Amadeus Mozart|Mozart]] was young, he and his sister [[Maria Anna Mozart|Marianne]] played a duet of his composition at a London concert in 1765. The four-hand, described as a duet, was in many of his compositions which included five [[sonata]]s; a set of [[Variation (music)|variations]], two performers and one instrument, and a sonata for two pianos. The first published sonata or duet was in 1777.<ref>Miller, H.-M. (1943). The Earliest Keyboard Duets. ''[[The Musical Quarterly]]'', 29(4), 438–457.</ref>

In [[Renaissance music]], a duet specifically intended as a teaching tool, to be performed by teacher and student, was called a [[bicinium]] (''see [[Étude]]'').
