Tolgahan Çoğulu’s Adjustable Microtonal Guitar
The Adjustable Microtonal Guitar was designed by Turkist guitarist Tolgahan Çoğulu in 2008. This microtonal guitar allows players to easily change positions of frets, and to add/remove fret(s) to tune the instrument to various microtonal scales. This flexibility in micro-tuning opens incredible opportunities for guitarists to expand their music beyond the restriction of the Western scale of temperament. This is an amazing contribution to the development of the classical guitar and its music.
In this video, Tolgahan Çoğulu introduces the main features of his 8-stringed adjustable microtonal guitar and performs various pieces.
The following video presents a performance of the Microtonal Guitar Duo (Tolgahan Çoğulu on 8-stringed guitar and Sinan Cem Eroğlu on fretless guitar)
