Microtonal Guitar LEGO Fretboard
Guitarist and father Tolgahan Çoğulu from Turkey specializes in building microtonal guitars that incorporate alternate tuning scales as found in traditional Turkish music and solving the ‘major third problem.’ This problem arises due to the nature of dividing the octave into 12 equal semitones. His latest project all started two years ago when his son Atlas made the adjustable microtonal guitar keyboard using LEGO. Once the keyboard was completed, he asked if he could use it on the real guitar, and the rest is history. Read more for a video about the build and a demonstration of the completed instrument.



Simply put, they removed all the frets and placed only five of them to play the C major scale. Then, by changing the location of the three frets, Tolgahan showed Atlas how they can make the C minor scale. Last, but not least, he showed the Balinese pentatonic sequence, which contains three microtones. The frets themselves are also 3D-printed and were fitted onto the neck using the standardized LEGO stud. Each fret piece spans only one string space, thus allowing them to have a completely different set of fret divisions.
