As a musician, you know posture is important. Maintaining good posture while playing has probably been drilled into you since your very first lesson with whatever instrument you play. You’re taught to keep your spine straight, stomach sucked in, chest high, and shoulders back.
The music industry has a problem. How many times have you been told that pain is a necessary part of being a musician? That you must be in physical pain to express pain in your music. That to emote suffering in your music, you yourself must be suffering.
