We have a 64-key Melodigrand. Finding a #piano tuner was harder than expected, so I bought a tuning hammer, some mutes, and decided to give it a go. The entire piano was nearly a half-step flat after 5 years. And many unisons were ... not unisons

My first DIY tuning was successful and painless for a few reasons:

1. The Tuner app on @fdroidorg is phenomenal - https://f-droid.org/en/packages/de.moekadu.tuner/
2. This piano only has 2 strings per key on the trebles (instead of 3)
3. The piano only has 64 keys (instead of 88)

I would still attack a full 88er with 3 strings per treble, but it would take longer.
