10 great ways to ruin your voice

  1. Shouting over loud music in a bar/restaurant
  2. Smoking/drugs/excessive drinking
  3. "Placement"
  4. Belly breathing 
  5. Pushing or any other kind of straining
  6. Believing that singing is like sustained speaking
  7. Doing anything "from the diaphragm"
  8. Neglecting the development of either the chest register or the falsetto
  9. Depressing your larynx through conscious effort or by mechanical means
  10. Most group warm-ups (Better to warm up alone beforehand, then lip-synch through the group drills)
I'll eventually blog about all these detrimental practices.
