Period instruments
Does old music sound better on period instruments?  Musicians do not all agree about this question and they still argue a lot about the way that some of the music should be played.  However, it is important to listen to the way that period instruments are played.  Musicians such as the violinist Andrew Manze have done a lot of research in old books and old music and have done a lot to make people rethink the way in which music from former centuries should be performed.
