Romanus Weichlein (1652-1706) received his first musical training at the abbey of Lambach and entered the Benedictine Order in 1671. He went to Salzburg to study at the University where he became a doctor of philosophy in 1673. Here he also got acquainted with Heinrich Ignaz Franz von Biber. Returning to Lambach, he later became chaplain and musical director of the Benedictine convent of Nonnberg in Salzburg.

His oeuvre isn't very large, and it is quite possible that some of it has been lost. What has been left is this collection of sonatas, as well as a number of masses. Encaenia Musices contains 12 sonatas for two violins, two violas and bc, with two additional trumpets in the Sonatas I, V and XII.

There are similarities with music by other Austrian composers, like Biber and Schmelzer. Even so, Weichlein's sonatas have their very individual traces as well.

“These sonatas by Weichlein are really excellent music, and there is every reason to play them alongside the music of renowned masters of Austrian late 17th-century music. Ars Antiqua Austria has done us a favour by recording this collection.” - Musica dei donum
