Baroque soloists "fattoamano"

In earlier times, anyone who gave their Opus 1 to print sent out a clear signal: They had completed their musical apprenticeship and the time had come to present their first works to the public. At the turn of the 17th and 18th centuries, it was customary to present trio sonatas for two violins and basso continuo in such an opus 1. The Roman violin master Arcangelo Corelli did this in 1681, as did many of his colleagues.
