Saxony's Court Orchestra was for many years the working sphere of influential composers known far beyond her borders. Maria Antonia Walpurgis, wife of Friedrich Christian, Elector of Saxony was especially active during the years of her regency with generous and skillful sponsoring of the arts and artists. Works by Ferrandini, her teacher for composition, harpsichord and singing, or Porpora (teacher of Carlo Broschi, the castrato better known as Farinelli), whom she engaged as a second singing teacher at the Dresden Court, convey a lively impression of those times.
