It all began in the summer of 2012...
Our founder Lander Pinson was living on a farm near the Danish Technical University, where he attended his mechanical engineering classes every day. In the evening he would look for opportunities to play piano... only, his living space was quite small and had quite some stairs to reach it.
From his earlier experience with tuning and servicing pianos, he remembered the pleasing sound of a piano hammer hitting a single string instead of 3 strings. He found a conventional upright piano available for little money (due to people moving out and not having the resources to take their piano with them), cut out the middle section of the sound-body, kept 4 octaves of the keys and assembled these to the smaller sound-body with a custom steel frame, welded from some scrap metal. The result is shown in the video below.
The major conclusion? Don't underestimate the total tension that piano strings exert on the frame. It actually compares to the weight of several cars.
The result? A small acoustic piano with one string per key, tuned 3 half tones lower compared to conventional pitch (hency the sound somewhat comparable to a Rhodes piano).
