Mozart's Mass in G major, K. 49/47d), is his first full mass. It is a missa brevis scored for SATB soloists and choir, violin I and II, viola, and basso continuo.

Mozart wrote the Mass in G major at the age of 12. It was however neither his first setting of a part of the mass ordinary – two years earlier he had already composed a Kyrie (K. 33) —, nor was it his largest composition with a religious theme up to date: his sacred musical play Die Schuldigkeit des ersten Gebots had been premiered in the previous year.
