can it tune Steinway Grand piano?

I used it on my 1913 Steinway.... but, it's really a bit short to get enough torque/accuracy...

Does it work with yamaha

I don't know, but it doesn't work on my Young Chang piano. :-(

Does this work with Melody Harp for children?

the tuner hammer fitting is the size of a simple 1/4 inch drive socket

Will this work with an Autoharp or dulcimer zither pins?

If the pins are like piano tuning pins then ya. But I’m not really sure
