A talented cellist was scheduled to play before a very critical audience. Although he had a fine instrument, he was not satisfied with the quality of its sound. So he said to his colleague, “Tonight, this cello must yield its full resonance and vibration of tone. I’m going out to buy some tested strings.”
When asked how these strings are tested he replied, “First they’re put on a rack and stretched and strained to take all the unsteadiness out of them. Then they are hammered. Then they are put through a chemical test. This is what enables them to produce a perfect and full tone.” Later, when he attached the tested strings and tuned the instrument, the music was noticeably warmer and richer than before.
