Tuning forks as resonators --- When 2 identical tuning forks (the same Hz) and sounding boxes are placed next to one another. Striking one tuning fork will cause the other to resonate at the same frequency, just like a vibrating string. When a weight is attached to one tuning fork, they are no longer identical. Thus, one will not cause the other to resonate. When two different tuning forks are struck at the same time, the interference of their pitches produces beats.
