I made a couple of Thumb Pianos for the kids. But being a non- musical guy I now have to figure out how to tune them , not that they care. They are easy to make just a box with some hardware on top.

One is Walnut with Oak sides and Cypress on top , its 5 1/2×7 x 1 1/2 , this one has a nice deep tone to it.

More like what I thought they would sound like.

The other one is Walnut with western cedar side , it’s a little smaller with a bit of a tapper. This one doesn’t

have as nice of sound to it , maybe I will be able to help it by playing with the tuning .

The metal key things are from an old lawn rake , after I’m done trying to tune them I’ll cut them to look a little better.

Please comment even if I did it wrong.

First one that I have ever seen. They are interesting looking devices. I would think you would tune one by adjusting the length of the keys wouldn’t you. what do they sound like when you play them? I might need to make some of these. Tell us more about them. What is the metal you used? those look like a leaf rake tine. Play us a tune. ha ha Thanks for the post.

Paul, Very nice looking pieces. BTW, your photography is superb. I have no idea but there is a possibility that trimming off the back sides may affect the tuning so it may be a multi-step process. Also, I’ve heard that you can tune a piano, but you can’t tuna fish. Again, nice job.

Nice one Rance.

Paul, the only thing that will affect the pitch is the length of the fingers on the hole side. In other words the distance from the metal bar underneath them to the end. If anyone in your family plays guitar and has a chromatic tuner, you can use that to see what notes are sounding when you flick each finger and adjust the length until the correct tones are heard. It might be a bit hit and miss (pun intended) though.

Paul, the Kalimba looks great. If you want to change the sound tone you can also add two 1/2 holes on the underside. Located about where your index fingers are when your are playing the instrument. Something like opening and closing a hole in a flute but not required to play.

Thanks everyone…
I just did a google search for Kalimba / thumb piano to find out how to make one.

I do know how to change the tune , I just don’t know what a G or any other note sounds like .

amagineer.. I think I might try the holes in the bottom.

Jim I’ll look into that app I think that is what I need.

Paul,
I just found a ‘on line tuner’ that might be helpful:

Ron that looks perfect.

I have a couple of other instruments in mind to make that will need to be tuned also.

They’re wonderful. Did you build the mechanism or purchase it? If purchased, I’m dying to learn of the supplier. Nice work!
