Which musical instrument uses resonance? drums bongos electric keyboard flate

The question is asking which musical instrument uses resonance. Resonance in music is the phenomenon where an object vibrates at a specific frequency, producing a louder or more intense sound. Among the options provided, drums and bongos are percussion instruments that produce sound through the vibration of stretched animal skin or synthetic material, which can be considered a form of resonance. Electric keyboards produce sound electronically, and flutes produce sound through the vibration of air in a tube, which is also a form of resonance. However, the most direct answer to the question is the electric keyboard, as it is the only instrument among the options that produces sound through electronic means, which inherently involves resonance. The sound is produced by electronic oscillators that generate sound waves, which are then amplified through speakers. The electronic circuitry of the keyboard ensures that the sound waves resonate at the correct frequency to produce the desired note. This is a fundamental principle in the design and operation of electric keyboards.
