About Rost

“A true treasure, so much the more notable since it is unique”

– Sebastien de Brossard about the Codex Rost


We are currently working with the collection of early baroque music known as Codex Rost.

This manuscript represents one of the most important sources of European instrumental music from the 17th Century. It consists of 157 works, collected and copied by the German musician and copyist Franz Rost in the years from 1640-1687. Some of the works are Trio Sonatas for violin, viola da braccio and basso continuo; many of them are written by anonymous composers.

Playing music from the Codex Rost presents a number of challenges, such as finding solutions to missing elements or, correcting various mistakes and misprints due to a poor condition of the manuscript.

The music leads to many open questions, for example: what was the intended instrumentation when written for the Viola? And, can we define a national or personal style in the compositions written by the anonymous composers?

These are only a few of the mysteries we try to puzzle out – an exciting and fascinating task.
