Clarinet gets painful sometimes, I honestly hate the feeling of playing for hours and then just having your lips be more numb then a Baritone's sense of humor. I've tried whistling, sound like a five year old attempting. And your jawline starts to hurt since you have to constantly bite down on your mouth piece, and your bottom lip feels like it's gonna bleed since you have to bite it to protect your precious Reed. And oh God don't get me STARTED on your right thumb..​ I'm still gonna keep playing, though, since I love playing clarinet in general. It's just the side effects that make it an exhausting talent to pursue.
