Bowed keyboard- Streichklavier #8: A short recording of bowed keyboard

« Part 7: at the fall music festival in Ironton MO Part 8 of Bowed keyboard- Streichklavier series no next part

For those of you that have not seen this yet, a short recap…A harpsichord type instrument that uses a rosined nylon belt driven by a foot treadle to bow the strings when a key is pushed. This is a little video I made while it was working halfway decent. The first little clip is shot with video mode on still camera- the rest is an audio recording with older shots of construction to fill the video void. I plan on adding another keyboard that will pluck strings similar to a harpsichord, but with softer plectrums to sound like a harp. The squeaky noises are little rollers that need oiled. The belt also slipped once if you hear something like a seal barking…

Well done Jon looks like a good and interesting build I think GaryK built a very similar instrument.

Neat! I’m having trouble hearing when the bow stroke changes direction. Is that when on the held notes it seems to get quieter then pause?

Thanks guys!

A1Jim, I actually pestered Gary quite a bit on details of how he built his harpsichord. Those were some nice instruments he built.

Dan, the pause you hear is probably the splice in the belt- It makes a dead spot for a second. It is actually always running in one direction. I hope to get the splice shorter…I’m refining my splicing process, so the next belt I put on should have less of a lag spot.The belt is a loop that runs around a set of pulleys like the fan belt on a car. It is made from 1/2” nylon ribbon. It is the best material I’ve found for this particular setup, and it’s cheap!

Thanks Karson! hopefully after some more refining and the addition of other features, it will sound a little better.

Jon, thanks for the explanation, that’s why I wasn’t hearing the rest of what I expected to from a bowed sound. Love to see one of these in person some time!
