fixing sound djembe quality

Check the head tension: The drum head should be tight but not too tight, as this affects the tone of the drum.
Check the skin quality: The quality of the skin can affect the sound of the drum. If the skin is old or damaged, it may need to be replaced.
Experiment with playing technique: Try playing the drum with different strikes, hitting different parts of the head, and using different parts of the hand.
Check for resonant body issues: Ensure there are no cracks or other issues with the resonant body that could affect the sound.
Seek professional advice: If you’ve tried the above suggestions and the drum still doesn’t sound good, consider seeking advice from a professional drum maker or repairperson.
