The thing that most people get confused with is the difference between a percussionist and a drummer. A percussionist can also be a drummer, but a drummer is not always a percussionist.
To expand on that point. A percussionsit can play a range of instruments, not just your typical drumkit. It can include timpani, mallet percussion (xylophone, glockenspiel, marimba, etc.), cymbals, gongs and random untuned percussion instruments.
A drummer is focussed on the main drumkit, accompanying a band or group and most that i have come across don't have any idea how to read sheet music or written melody parts which a percussionist would know.
Yes at times is can get boring (counting 202 bars in a sibelius piece to hit one note is boring) but it can also be incredible fun and rewarding. With such a wide range of instruments, larger than any other section, we can basically do anything. Also i find that percussionists have more freedom. We can eat up the back whilst others a practicing and go almost anywhere we want to because we are expected to be always making adjustments to all of our instruments of moving some around.
So yes at times percussion can be boring but it is also fun (film scores have HEAPS OF PERCUSSION). however donm't mix up a percussionist and a drummer, because they are not the same thing
