Stringing Underway

A piano "out of tune" gives the musician a false sense of tone and hinders their development.  

Tuning is the art of adjusting the string tension.  Piano manufacturers recommend tuning new pianos 4 times during the first year and every 6 months thereafter.  The 230 odd strings are stretched at an average tension of from 150 to 200 pounds apiece, so that the iron plate, together with the heavy wooden frame, carries a strain totaling from 18 to 20 tons.  Humidity changes the piano's pitch.  When the indoor humidity goes up, the piano's pitch will go up and down when the humidity goes down.
