The flute occupies an important place amongst all the instruments celebrated by Vivaldi, il prete rosso, in his concerti. All evidence points to the instrument concerned being the recorder, given that it was still extremely popular in Italy at that time. The single publication of concerti that Vivaldi did not compose for the violin (opus X) was marked by him as being for the flute, as were the Concerti da Camera, in which the instrument rivals the violin, oboe and bassoon in virtuosity. Performing the recorder parts on this new release is Frederic de Roos. Frédéric de Roos is the recorder professor at the Royal Conservatorium of Brussels of which he has also been the director since 2003. After obtaining a university degree in musicology, he focused his studies on the recorder repertoire of the 18th century. He regularly presents conferences and seminars on the language of the baroque and gives courses and master classes both in Belgium and abroad.
