Undergrad Optimizing Drumstick Bounce: Finding the Magic Fulcrum Point

Click For Summary
SUMMARY

The discussion focuses on optimizing the bounce of a drumstick by finding the ideal fulcrum point. It is established that the fulcrum must be positioned between the center of mass and the butt end of the drumstick to achieve maximum bounce. The optimal position is approximately 2/3 of the way from the center of mass to the butt end, specifically at a distance of 155mm for a 450mm stick. The concept of the drumstick acting as a compound pendulum is emphasized, with the period of oscillation being influenced by the pivot position and the radius of gyration.

PREREQUISITES
  • Understanding of compound pendulum mechanics
  • Familiarity with the concept of center of mass
  • Knowledge of mechanical impedance matching
  • Basic grasp of oscillation periods and their formulas
NEXT STEPS
  • Research the physics of compound pendulums and their applications in musical instruments
  • Explore the concept of radius of gyration and its impact on oscillation
  • Study the effects of different surfaces on drumstick bounce and performance
  • Investigate the mechanics of air drumming systems like Aerodrums
USEFUL FOR

Drummers, music educators, and physics enthusiasts interested in the mechanics of drumsticks and optimizing drumming techniques.

$$\alpha = \frac{\tau}{I} = \frac{F\frac{L}{2}}{\frac{1}{12}mL^2} = \frac{F}{m} \frac{6}{L}$$

Thank you. The additional step in between makes it crystal clear.

Not gonna lie, this honestly what i was expecting when I clicked through.

The more loose the head, the less the bounce, if you want to learn wrist control and build up all those ancillary muscles, you play your double stroke roll on a pillow, zero recoil.(an aside)
Loosely related. I tried playing a bit. I could never figure out to achieve a bass drum beat. The pedal would kick back too fast and aggressively, ruining the rhythm. Probably me being too timid.

But maybe it would be best to cleave off a thread about general drum physics.
