60 days or so on the LV-4. When Priantz, on YouTube, plays this instrument, he tilts the pitch antenna away from him at what looks like 15 degrees. I believe the tilt is meant to spread out the higher octaves a bit.
He plays this model as well as I’ve heard it played, and he’s also tall and sets the instrument low. All of this is appealing to me.
I’m experimenting with the 15 degree tilt. After a few days of it, I’m trying 20 degrees. With a tilt, it seems like it’s easier to get G4 to G5, G3 to G4, and G2 to G3 within a hand span though not necessarily exact, and with zero beat in front of me. Aspiring Thierry tuning without much experience.
