Piano tuning adjusts the tension of the piano's strings to ensure that the musical intervals between notes are in harmony. The process involves using a tuning lever to turn the tuning pins and adjust string tension, mutes to silence untuned strings, and a tuning fork or electronic device to set the first note. Pianos are typically tuned to a modified version of equal temperament, where the interval between half-steps is constant, and the octave is the only perfect interval. Frequencies of notes follow mathematical ratios, with an octave having a 2:1 ratio and a perfect fifth a 3:2 ratio.
