To most piano buyers and owners, a piano's tone is probably its most important aspect, but also the most difficult to quantify or describe. Likewise, the shaping of the tone by the technician through the procedure known as voicing involves unfamiliar terminology, and techniques that are difficult for technicians to communicate to the customer.
