I was wondering if you have heard the Schumann's violin concerto and if you like it! There is a great discussion about Schumann's mental state when he composed it and whether this can be seen (listened) in his concerto or not.
Even more interesting is the tempo of the concerto. There is no consensus about the tempo -especially of the third part- at which the concerto should be played. Schumann has metronome notations, but they are either deemed to be signs of his mental state or to be extremely slow.
Listen to this recording by Harnoncourt and Kremer (http://www.youtube.com/watch?v=39ou6...eature=related) which follows Schumann's instructions and another recording by Joshua Bell (http://www.youtube.com/watch?v=EWSms...eature=related) and Cleveland Orchestra and say which one you prefer and if you like the concerto.
