Relax your throat, jaw, and tongue
Breathe deeply from your diaphragm
Start with a comfortable low hum
Keep the sound steady and controlled
Shape your mouth slowly to change resonance
Practice producing a strong drone tone
Experiment with moving your tongue and lips
Listen for overtone changes in the sound
Use short practice sessions at first
Stop if you feel pain or strain
Hydrate well before and after practice
Practice regularly to build control
