The phenomenon of new lyre running out of tone ——a new lyre, or when changing new strings, because the strings are in a relaxed state at the beginning. When the strings are tightened, the strings tend to automatically return to their original state after being under tension, similar to pulling a rubber band, so the new piano you just bought may be out of tune. Running-in period——After each practice, you can slightly increase the tone of each string to help stabilize the strings.
