Johann Gottlieb Graun became a member of the small court orchestra of the Prussian Crown Prince Frederick in Ruppin in 1732, which Carl Heinrich also joined in 1735. With Friedrich's ascension to the throne in 1740, Johann Gottlieb was appointed concertmaster and Carl Heinrich kapellmeister of the royal court. Johann Gottlieb remained until the end of his life closely linked to Frederick the Great, as concertmaster and chamber musician. Whilst his brother Carl Heinrich became an important figure at the new Berlin Court Opera, Johann Gottlieb strongly influenced the musical life of Berlin and early classicism in general as a violinist and composer.
For such an outstanding composer, relatively little is known about Vivaldi's life beyond the fact that he was born and raised in Venice. This is ironic, considering this great Baroque composer's close association in the public's mind with everything Venetian – an association only bettered by Canaletto.
Vivaldi's father was a violinist at St. Mark's, and there are indications that Antonio received his early musical schooling from within the family. He is understood to have trained as a priest, and was ordained in 1703. With this achieved, Vivaldi gave up any pretence to a life of the cloth and instead concentrated on his musical career. The same year he was appointed as maestro di violino by the Ospedale della Pieta, a charitable religious foundation for the education and upbringing of female orphans. His relationship with the Pieta was to last for the rest of his life, a central pivot around which his musical activities could revolve..

Bach’s two surviving oboe concertos both began as keyboard concertos that were later transcribed for oboe; their intended performer was probably Johann Christian Fischer, a virtuoso based in Potsdam in the mid 1760s. This would perhaps account for their technical and immensely challenging solo lines, which suggest that, like his father, Carl Philipp Emmanuel revelled in pushing instruments and performers to their limits.
Giuseppe Ferlendis (1755–1802) was an Italian oboist and composer. In 1777, he was appointed oboist at the Court Chapel of Salzburg, with a yearly stipend of 540 florins (higher than that of Mozarts by 40 florins). He died in Lisbon. His brother Pietro and his nephews Gerardo, Faustino and Antonio were all professional oboists.
"While working out the piece I was constantly aware that music already existed, that it had always existed, even the music that I was writing. It is merely necessary to trust what you hear around you and in you, and to realize it in a score. 'Fixed form' and 'open' are the same thing".
