Some people are like a piano out of tune. They need to tune up their faculties to work in harmony. To have a good piano, it is not enough to have a rose-wood case and a perfect sounding board with every wire in its place. The whole piano is of very little use until the strings have been tuned to work together. It must be tuned to a certain pitch, to a certain keynote; otherwise it is only a box of jingling wires.
