Final answer:
Percussion notes that are hyper-resonant refer to the strong amplification of sound produced by percussion instruments like the marimba. Resonance chambers, such as gourds or pots, are used in these instruments to amplify the sound and the resonant frequency can be adjusted by adding water.
Step-by-step explanation:
Percussion notes that are hyper-resonant refer to the strong amplification of sound produced by percussion instruments. Resonance is a phenomenon in which an object vibrates at its natural frequency when exposed to vibrations from an external source. In the case of percussion instruments like the marimba, the use of resonance chambers, such as gourds or pots, helps to amplify the sound produced by the instrument. The resonant frequency can be adjusted by adding water to the chamber, allowing for greater control over the tone.
