Tips for buying a baby grand piano are to consider the materials the piano and keys are made of before purchase, to choose an acoustic baby grand piano for optimal tone quality or an electric piano for affordability, and to predetermine a place to keep the piano before purchase. The size of the available space affects the size of the piano, which changes the sound of the instrument — as do the temperature and levels of humidity in the room.
To qualify as a baby grand piano, the instrument must be less than 5 feet 6 inches in length. The instruments with the richest timbres are at least 5 feet 4 inches in length. To maintain the sound of the piano, it is necessary to keep it in a location with optimal temperature control and dry air. A baby grand piano in a humid room requires more frequent tuning — up to four times per year — than a piano in a dry room, which only requires tuning twice a year.
The composition of most baby grand pianos is wood, though some are lacquer or fiberglass. Avoid cheap baby grand pianos made from plastic blends or other materials. A good tip is to consider the composition of the keys; while exquisite, it is much easier and cheaper to replace ceramic keys than to repair or replace keys made of ivory blends, bone or mother of pearl.
