High humidity levels seem to be widespread in Catalunya – as the common problem of tight keys shows. Steinway, Yamaha, and fortepiano were all in need of having their keys released at the balance and/or chasing points:
I am returning to service this Steinway model B (in The Crypt, Cambrils).
Releasing the keys on a Yamaha C3. The balance hole, in particular, of each key has become tight again, 4 years after having been released – such is the problem of humidity in this lovely region of Spain.
Releasing the keys on a Gerard Tuinman fortepiano: all bearing points – balance hole, chasing, front guide (all wood, of course) tended to be tight.
