Bork-Frithjof Smith startet his musical training at the age of five, learning the recorder, the violoncello and the trumpet. At the age of twelf he discovered the cornetto, which then became his main instrument. He studied Early Music with the main instrument cornetto at the Schola Cantorum Basiliensis with Bruce Dickey, graduating in 1999. One of his main passions is still neglected cornettino, which he aims to make known again.
In 1997 he founded the ensemble Les Cornets Noirs with Gebhard David. Since many years Smith performs with many well known ensembles for Early Music, such as the English Baroque Soloists, Concentus Musicus Wien, Musica Fiata, Huelgas, His Majesty's Sagbutts & Cornetts, musica fiorita, Weser-Renaissance, L'Arpegiata, La Petite Bande and Concerto Italiano. He performs at important festivals all over Europe and Israel, as well as in North and South America.
More than 90 recordings for different lables document his musical career. From 2008 to 2017 he has been teaching cornetto and diminutions at the Hochschule für Musik Trossingen; in 2017 he became the successor of Bruce Dickey, leading the cornetto class at the Schola Cantorum Basiliensis.
