Prelude in G major from The Ecclesiastical Organist bk 2.

Caspar Ett (5 January 1788, Eresing – 16 May 1847, Munich) was a German composer and organist.

Having completed his secondary studies at the "Paedagogium" in Munich, now called the Wilhelmsgymnasium, in 1804, Ett continued his studies at the Electoral Seminar in Munich, and in 1816 became the court organist at St. Michael's Church. He was also the music teacher of King Maximilian II of Bavaria.

Ett composed for the Catholic litury as well as for Greek Orthodox and Jewish worship. He played a role in reviving choral music from the 16th to the 18th century.

He wrote two well known hymn tunes Oriel and St Martin.
