The audio begins with the soothing resonance of an F-Major G note, produced by blowing gently across the opening of a glass bottle. The distinct, enchanting melody is a result of the bottle acting as a Helmholtz resonator, an object that amplifies certain frequencies of the sound waves passing through it. The glass, a non-porous material, causes the sound to vibrate, creating a pure and clear note that echoes softly, lingering in your ears. The audio brings a sense of calm and tranquility, audibly demonstrating the harmonious blend of music and science.
