Touch, in its simplest form, refers to the effort required to press the piano keys. Unfortunately, the specifications provided by the manufacturers, expressed in grams, don't do justice to this complicated subject. The apparent touch can be very different when the piano is played fast and loud than when it is played soft and slow, and this difference is not captured in the numbers. If you are other than a beginner, be sure to try it out both ways.
Advanced pianists tend to prefer a touch that is moderately firm because it provides better control than a very light touch and strengthens the muscles. Too light a touch, even for a beginner, can cause laziness, but too firm a touch can be physically harmful over time. The touch of most new pianos today is within a reasonable range for their intended audience, but the touch of older pianos can vary a lot depending on condition. A piano teacher may be able to assist in evaluating the touch of a piano for a beginner, particularly if considering an entry-level or used piano.
Piano tone is also very complex. The most basic aspect of tone, and the one most easily changed, is its brightness or mellowness. A bright tone, sometimes described by purchasers as sharp or loud, is one in which higher-pitched overtones predominate. A mellow tone, sometimes described as warm, dull, or soft, is one in which lower-pitched overtones are dominant. Most pianos are somewhere in between, and vary from one part of the keyboard to another, or depending on how hard one plays. The key to satisfaction is to make sure that the tone is right for the music you most often play or listen to. For example, jazz pianists will often prefer a brighter tone, whereas classical pianists will often prefer one that is mellower, or that can be varied easily from soft to loud; i.e., that has a broad dynamic range. However, there is no accounting for taste, and there are as many exceptions to these generalizations as there are followers. A piano technician can make adjustments to the brightness or mellowness of the tone through a process known as voicing.
Another aspect of tone to pay attention to is sustain, which is how long the sound of a note continues at an audible level, while its key is depressed, before disappearing. Practically speaking, this determines the ability of a melodic line to "sing" above an accompaniment, especially when played in the critical mid-treble section.
Most pianos will play loudly quite reliably, but providing good expression when played softly is considerably more challenging. When trying out a piano, be sure to play at a variety of dynamic levels. Test the action with your most technically demanding passages. Don't forget to test the pedals for sensitivity commensurate with your musical needs.
Room acoustics have a tremendous effect on piano tone, so you'll want to note the extent to which the acoustics of the dealer's showroom differ from those of your home, and make allowance for it. Hard surfaces, such as bare walls, tile, and glass will make the tone brighter. Absorbent surfaces—upholstered furniture, heavy drapes, plush carpeting—will make it mellower. Once the piano is in the home, a technician may be able to make adjustments to the tone, but to avoid unpleasant surprises, it's best to buy a piano whose tone is already close to what you want. Adjusting the room acoustics through the strategic use of wall hangings, scatter rugs, and furniture can also help. See the article "How to Make Your Piano Room Sound Grand," elsewhere in this issue.
The Piano Warranty
The majority of pianos never generate a warranty claim. That said, few people would sleep well worrying about potential problems arising in such a major purchase. Key warranty issues are: what is covered, for how long, and who stands behind the warranty. The overwhelming ma-
jority of new-piano warranties cover the cost of parts and labor necessary to correct any defect in materials or workmanship. The warrantor (usually the manufacturer or distributor) also generally reserves the right to replace the piano should it choose to in lieu of repair. The warrantee (the customer) generally makes warranty claims to the dealer who, upon approval of the warrantor, makes the necessary repairs or replaces the instrument, as applicable. If the dealer is out of business, or if the customer has moved, warranty claims are made to the new local dealer of that brand, if any, or directly to the warrantor.
