My piano sounds tinny or dull sounding after the piano was tuned. Can the hammers be voiced to improve its overall sound after the piano is tuned?
Yes. Sometimes the hammers are so worn out that little sound is produced especially in the upper treble of the piano. Tuning depends upon quality hammers to produce the sound that is pleasant to hear. So the tuning can be helped by doing some basic maintenance on the hammers called tone regulation and voice regulation to improve its overall sound after the piano is tuned.
