Camilla de Rossi, Romana was one of four women who composed oratorios in Vienna in the early 1700s. She likely had musical training on stringed instruments, as evidenced by the exploration of unique instrumental colors in her compositions. All of her oratorios were written for solo voices and orchestra, alternating throughout between recitatives and arias. Four of de Rossi’s oratorios, written for Holy Week and other church celebrations at the Imperial Chapel in Vienna under Emperor Joseph I, and one cantata, have survived. Her first oratorio, Santa Beatrice d'Este (1707), was commissioned by the Emperor and later performed in Perugia in 1712. Il Sacrifizio de Abramo was written for Holy Week in 1708 and employed a single reed woodwind, the chalumeau, for interesting effect.
The central question was always about how much needs to be added to the surviving notes in order to make Poppea viable on stage. Gardiner and his advisers believe that nothing needs adding and that the 'orchestra' played only when explicitly notated in the score and was a very small group.
The Codice di Staffarda is a musical codex from Staffarda Abbey (Santa Maria di Staffarda), a Cistercian monastery located near Saluzzo in north-west Italy. The codex includes works by composers including the otherwise unknown Engarandus Juvenis and Antoine Brumel.
Extraordinarily, Alessandro Scarlatti (who died in 1725 and forms a strong bridge between the mature Baroque and later classical traditions, according to musicologist Edward Dent) wrote some sixty-four operas, twenty oratorios, hundreds of chamber cantatas, and a host of madrigals, masses, motets, toccatas, concertos, sonatas and symphonies. Very little of this is heard today, sadly, except in specialist circles. Perhaps one of the more popularly performed pieces is 'Abramo, il tuo sembiante' (a Christmas cantata). When Handel visited Italy between 1706 and 1710, he met Scarlatti and may even have studied with him. This performance of said cantata is well within the Italian style - clear lines and intricate ornamentation.
