Why maintain a piano?
The piano is a highly developed, complicated piece of instrument. It contains about 240 different lengths of highly tensioned wire; in other words, approximately 160 lbs. per note, and a 15% increase in the bass, giving you an overall strain on the piano frame of approximately 18-20 tons of pressure. These lengths of wire make up 85 to 88 notes, spread across the musical range. In addition, for each note, there exists a mechanism, which in the case of an upright piano, contains up to 14 different moving parts. In the case of a grand, up to 22 parts moving parts, per note. Since the piano must be maintained at a specific tension to achieve a good musical sound, the matter of maintenance becomes an on-going process. Since a piano consists mainly of wood and iron, all of this is subject to movement. The movement of the wooden soundboard, framework, causes the wires to change tension without prompting by the user. Thus, it becomes necessary to set up a minimal schedule of every six months
