A Piano Guide
We sincerely hope the following information helps you appreciate the craftsmanship and effort taken to produce and maintain an amazing instrument…the piano.
The piano is, I believe, unique in our culture in the way it weaves music, craft, history, business, science, and engineering – both low-tech and high-tech – into a remarkable tale worth telling.

Caring For Your Piano
Where to Place Your Piano
Because of the damaging effects of hot dry air, try to place your piano away from radiators, heat ducts, or any source of hot dry air. Avoid placing it near a window, outside door, or any source of moist air. Often, the best way to avoid all of the above is to place your piano against or near an interior wall. With upright pianos, allow an inch or so of space between the piano and the wall, as the wall will reflect the tone emitting from the back of the piano and act as a secondary sounding board.
Care of the Finish
If the outside case is a wood grain, you can clean it with a soft cloth (cotton or cheese cloth works well) slightly dampened with furniture polish. If you have an ebony or ivory finish, put 2 parts Glass plus with no ammonia to 10 parts water in a bottle and shake it. Then spray your cloth lightly and wipe the finish and keys. Always spray your cloth; never spray your piano directly.
Keeping the Interior Clean
The interior of your piano should be dusted periodically. You can use one of the smaller hose attachments on your vacuum cleaner to pick up much of the dust. If any children’s toys, coins, or other foreign objects should find themselves inside your piano, don’t try to remove them (unless it can be done easily). Your regular piano tuner/technician should have no trouble removing the object. If you do not have a regular piano tuner/technician, you can find one here, or call Rick Jones Pianos at (301) 345-5425.
Tuning Your Piano
It takes time for a new piano to “settle in” and adjust to the individual climatic conditions in your home. Correct tuning and servicing is particularly important during the first year. Manufacturers agree that a piano should be tuned twice a year. Rick Jones Pianos suggests that you take advantage of your free in-home tuning three to six months after delivery.
You’ll find that as your piano mellows, it will actually improve in performance, as long as it is tuned properly and at regular intervals. Rick Jones Pianos will be happy to arrange for a qualified tuner-technician to service your instrument on a regular basis.
Components of a Piano
The Action
The Damper
The Piano Sounding Board
Like a hi-fi speaker, a sounding board is a vibrating diaphragm. It must vibrate at exactly the same rate as the strings, and to work properly, must be under constant tension. This is accomplished by having the center of the board arched, or crowned, with the strings pressed down on the board where they cross the bridges.
So that it vibrates freely, a sounding board is usually only 1/4 to 3/8 of an inch thick. Ribs help strengthen the board and preserve the crown. Woods used in a sounding board obviously must be carefully selected and seasoned. Also, the heavy and massive cast iron plate that covers the sounding board never touches any part of the sounding board.
The Piano Strings (Wires)
The pitch or sound of each note is determined by the number of vibrations per second of each string’s “speaking length” (the part between the wooden bridge at the bottom of the sounding board and where the string bears on the ironplate). The number of vibrations given off by a string can be controlled three ways:
- By tension on the string. (The lower the tension – the lower the pitch).
- By length of the string. (The longer the length – the fewer vibrations and the lower the pitch).
- By diameter of the string. (Wrapping additional wire around a string lowers the pitch)
These three factors are called the scale. Piano manufacturers obtain the 88 different notes by varying the scale.
To lower the pitch a single octave, you must double the string length and so on, redoubling all the way down the scale. however, if you started with a two-inch speaking length string, kept string diameter and string length constant, when worked down all 88 notes, you would end up with a 22-foot upright piano.
This is why strings in the bass section are wound with wire. In the extreme bass, another wire is used around the first wrapping because a single winding heavy enough for the proper diameter couldn’t be wrapped tightly enough around the center wire.
