Resonance Box with C-E-G-C Tuning Forks and Hammer

This Eisco Labs Resonance Box with Tuning Forks set demonstrates the formation of a basic major chord. Four steel tuning forks are mounted on a common solid wooden resonance box, producing frequencies of C (256 Hz), E (320 Hz), G (384 Hz), and C’ (512 Hz). A hammer is included for striking the forks. The wooden resonance box amplifies the sound produced by each fork, making the tones clearly audible in a classroom setting. This set is ideal for demonstrating frequency relationships, resonance, harmonics, and the physics of musical intervals in physics and music theory courses.
