The Renaissance of Baroque
A large part of the Baroque repertoire became forgotten during the 19th and 20th centuries, While some productions of important and famous pieces (Haendel, The Messiah, Bach Saint-John’s Passion etc.) took place, they were then played according to the Romantic taste of the time with much larger ensembles and slower tempos.
In the 1970s, Nikolaus Harnoncourt and Gustav Leonhardt, then followed by musicians such as William Christie, Jean-Claude Malgoire, John Eliot Gardiner etc. paved the way for a newer generation of musicians who have now established baroque music as a significant part of the «classical» music repertoire in concerts and in recordings in Europe and the US.
They re-discovered forgotten instruments, and while researching on how this music was played during the Baroque era made it much more meaningful to a contemporary audience.
