Major pentatonic scale: Bo3 musical instrument
Bothree is a pentatonic instrument in which the sound is generated by vibrations of air. Built with gilded ebony, inlaid with tortoiseshell and turquoises framed in silver. Eleven tonal keys and three harmonic buttons make Bo3 an easy and comfortable instrument to play.
Each note on the pentatonic C scale has a unique color associated with it. The sound and color associations are based on the order of points on the pentagram-shaped line.
The instrument is a reconstruction based on outlines found in ruins on Akra'batah desert. Those ruins are also known as 'the city of eternal C'. Some say that the instrument was crafted by an ancient civilization that arrived to Earth a long time ago.
The instrument can be used as a neuroenhancer, expanding consciousness through sound and color. It allows the mixing of neuroimpulses, combining them into eternal harmony.
