He was organist at Storkyrkan, the main church of Stockholm, and chief conductor at Kungliga Hovkapellet (the Royal Court Orchestra).
Arguably his most accomplished composition is an opera, Il Giudizio d'Aminta, written on the occasion of the birthday of future Empress Catherine the Great of Russia.
He started working as a substitute for his father as an organist in Storkyrkan, the main church of Stockholm, and from 1753 was permanently employed there.
There he received the commission to write the music for the opera Il Giudizio Di'Aminta (with text by Lodovico Lazaroni), performed as part of the celebrations of the birthday of the future Empress Catherine.
[1][2] He wrote an opera-ballet, Sveas Högtid eller De fria konsternas vördnadsoffer åt dygderna (with libretto by Gustaf Fredrik Gyllenborg), but only the overture has been preserved.
