The second most frequent need in piano service, voicing softens hammers hardened from the repeated striking of the strings. When your piano sounds excessively bright or loud, it is time for voicing. I will often do a little voicing for no extra charge, particularly on spinets, consoles, and uprights where it often takes very little time to tame down an errant sound. Pretax cost is $75-$150 if I'm already on site.
