The workshop
Ref. 06
A small workshop behind Naschmarkt.
Four technicians, one long bench and a room full of actions waiting their turn. We tune in homes and halls by day, and restore in the workshop in between.

Since 2004
Ears first, gauges second.
Voicewell started as one concert technician with a tuning hammer and a bicycle. Today we look after pianos in homes, schools, studios and twelve concert halls across Vienna.
We still set every temperament by ear. Electronic tuning devices are useful for checking, but a piano is not a sine wave, and the last ten percent of a good tuning is listening.
Restorations happen in our workshop on Gumpendorfer Straße, where an instrument can stay for months while we rebuild it properly.

A restoration, month by month
What happens while your piano is with us.
Month 1
Assessment & strip-down
Photographs, measurements and a written plan. The action and keys come out first.
Month 2
Soundboard & bridges
Cracks shimmed, ribs reglued, bridges recapped where they no longer hold the strings cleanly.
Month 3
Pinblock & strings
New tuning pins, often a new pinblock, and a fresh set of strings scaled to the original design.
Months 4–5
Action rebuild
Hammers, shanks, flanges and dampers rebuilt or replaced, then fitted back to the keys.
Month 6
Regulation & voicing
Thousands of small adjustments, then voicing until the instrument sounds like itself again.
Month 7
Case & delivery
Case work finished, piano delivered, tuned on arrival and again a few weeks later.
