Why do pianos need to be tuned regularly?

Piano strings are strung under tremendous tension, averaging 90 kilograms each. Hence, even if the piano is not played, the strings will gradually stretch with the passage of time and the piano will fall out of tune. Pianos need regular tuning at least twice a year to keep them up to pitch and playing the correct notes.
