Professional (orchestral/chamber) musicians, what is the most difficult mainstream piece you've ever played?
What is the easiest, as well?
Obviously, parts are different for each instrument, and some may be harder than others, but whatever instrument you play, there's always a difficult piece. I'm looking for violists and violinists primarily because I play the viola.
For the viola, Le Sacre actually isn't that difficult. Whenever we go high into treble clef, it's only lyric melodies with small range.
