Although there are only 88 keys, the average modern piano has over 230 strings, one string per note in the low bass, two strings per note in the upper bass, and three strings per note in the treble. Pianos made in the eighteenth century were not as powerful and used low-tension wire made from an alloy different from the wire used today.
Tension averages approximately 160 lbs. per string. All together, the strings are stretched to a tension of 18 to 20 tons. A concert grand piano may have a combined string tension of up to 30 tons.
The strings gradually increase in thickness and length from treble to bass, and bass strings are wrapped with copper to make them produce a lower pitch.
Pianos range in weight from about 300 lbs, for a spinet to almost 1000 lbs. for a concert grand.
There are 8000-10,000 moving parts in a piano.
