What is proved by Evelyn's method of recognizing high and low notes?

Correct answer: The body can understand different vibrations differently

The governing concept is that musical perception can involve touch and bodily vibration, not hearing alone. Evelyn Glennie learned that high and low notes produce different patterns of vibration, and she trained herself to recognise those patterns through different parts of her body. This ability developed through concentration, repeated practice and careful observation; it was not simply a response to loud sound. Therefore, option B is correct because it explains how the body can distinguish different vibrations. Option A confuses loudness with pitch, option C denies the discipline required, and option D contradicts Evelyn’s achievement after severe hearing loss. Her method shows that determined learners can develop alternative ways of understanding music.
