A look at some photos and video from the keyed monochord as part of the Acoustic Modular Stringed Instrument, wanted to finish this up before 2014 came to a close.
The module works as a stand-alone keyed monochord. It has a bottom plate & end plates where you can attach strings. Also, the octaves are independent and can be dropped into the acoustic modular stringed instrument. The design started off with a cardboard prototype. After some minor corrections, a wooden version was produced.
