Creating A Bed Monochord

Warmest Greetings! Here is a small video of the large bed monochord (aka. Pythagorean Monochord) I have recently made. This build took over three months at a cost of around $700. This is the third monochord Ive built and it is by far the largest. It is tuned to low E at the moment but can be tuned up or down a note as well. It has sixty-four strings made from quality spring steel piano wire. The pegs are home made from brass rod stock and the tuning pins are zither pins bought from Ebay.
