Voicing

Your piano also may require periodic voicing. The process of voicing can adjust the relative brilliance of a piano and provide an even gradation of volume and tone over the entire range of the keyboard. Voicing procedures may involve reshaping the hammers, the use of needles on the hammer felt and/or the application of special softeners or hardeners in order to produce the best sound possible.

What is a good tone? Tone varies, even among pianos of the same make and model. No matter what its size or cost, any good piano should provide a wide range of tone, from soft and sweet to loud and bright. The tone should be even from the lowest to the highest notes. Most of all, it should sound musical.

What does the perfect piano tone sound like? There is no single answer, because everyone's taste varies. Also, certain tonal characteristics are more suited to specific styles of music. A bright, lively tone might be best for jazz, whereas you might prefer a rich and dark sound for Beethoven's music. There are many different sizes and models of piano available in the market place; you chose your piano because it sounded good to you.

But a piano's tone changes with use. As the hammers wear and compact, the tone often becomes too bright and harsh, robbing the pianist of the ability to produce a sweet sound. As parts wear, the regulation (adjustment of the mechanical parts that transmit motion from the fingers to the hammers) becomes uneven, and the pianist loses control over volume and tone. This is most noticeable in quiet playing. A delicate pianissimo passage becomes very difficult or impossible to play, and some keys may not sound at all if played very lightly.
