After a piano is properly tuned, a technique known as 'voicing' can be used to drastically
change and improve the tone of the instrument. An excessively bright tone can be
mellowed, eliminating harshness. Likewise, if the tone is too mellow, the notes will not
'sing'. The correct balance throughout the 8 octave range from the bass to the treble will
give a well-rounded sound that is full and expressive.
In voicing, old worn hammers are first filed and reshaped to their original shape,
eliminating string-cuts, so that the hammer strikes the string with clean felt.
The hammers are then aligned to the strings so that they strike correctly, with full force. (If
you have a Grand Piano, the soft (left) pedal will not work properly unless the hammers
are properly aligned to the strings.)
Finally, the hammers are 'pricked' (if needed), to soften the felt and eliminate excessive
brightness and harshness. Additionally, it may be necessary to harden the hammers if
they are too soft, using a hammer hardener solution.
Keep in mind that the piano must be tuned before voicing is done.
