A study instrument · guitar
Spectrochord is a study instrument for improvisation. Chords, scales and phrases you can see on the fretboard — and hear.
It isn't a chord dictionary.
It's a place to think in sound and its colours —
in its sonic spectrum.
Every chord quality brings the scales that fit it — all verified, note by note. Every scale is shown on the fretboard. And every phrase can be heard, looped, and carried to the instrument.
Playing Outside
For the chord in front of you, Spectrochord ranks the twelve possibilities — from the most consonant to the most tense. Colour shows the distance; your ear confirms it. Each structure plays over your chord, and the inside notes light up on the fretboard.
Pentatonics, triads, arpeggios, whole-tone or complete scales — superimposed from any root. It's the map most guitarists spend years building by ear.
What it does
Twenty-two chord qualities, fifty-six scales and modes. For every pair, all the chord tones are contained in the scale — verified, not suggested.
A melodic vocabulary of its own — full permutations for the short cells, retrograde for the long phrases. Sequenceable across the whole scale.
As a scale or phrase plays, the sounding note lights up in every position where it lives. You see the fingering, not just hear it.
Mixes the chord's sequences and scales at a length you choose, plus one note that resolves. Save the best to a study list.
The samples are real guitar recordings, tuned and aligned note by note. Study sounds like an instrument, not a synth.
Any chord, scale and your phrase list on a sheet to print or take as PDF. What you study on screen follows you to the music stand.
Live
Position diagrams, the full fretboard and the chord tones — drawn with the precision of a score.
