 Gustave Mahler's 6th Symphony is an hour and a half long, and we of the first violins are playing nearly all the time, thousands of tricky notes running up and down and up and down, sweat pouring from our bodies. Meanwhile, there are 8 percussionists involved, most of whom are playing only a few measures in the whole piece- and there were 3 players who spent the whole concert drinking beer in the orchestra bar: they had to play only a few seconds of cowbells from backstage (which they could do comfortably from their seats in the bar, which is located directly behind the stage). And they get paid the same as we do. One lucky fellow gets to hit a giant wooden crate with a hammer the size of an oil drum. 
Audience liked it ok though.
