I recently moved a Bechstein 3/4 grand piano from my grandmother's house to mine. The piano is obviously out of tune, but my concern is that since it hasn't been played/tuned for 15 years, expensive repairs might be necessary and the tuning might not succeed. I have scheduled a tuner recommended by my teacher for next week, but I would like to get an opinion from someone on the forum. Thank you very much.
Well, a piano that hasn't been maintained for 15 years must be thoroughly examined. You need to rely on a good technician and evaluate tuning, regulation, voicing, and potentially restoration interventions. Check the condition of the strings and the hammer rail. Above all, check the friction of the mechanical pins.
