Sympathetic and Differential Tuning Fork Set
Get a tuning fork to sing out its note with- out ever touching it with this high-quality set. Set both forks at the same frequency with the open ends of the resonating boxes facing each other. Excite one fork to instill sympathetic resonance and then dampen it. The note on the other fork “rings on.” Explore what happens when two tuning forks sound at different frequencies by using the adjustable weights on one of the tuning forks.
