Chord Geometry
A chord is not an abstract concept - it is a geometric shape. Twelve notes sit evenly on a circle: a triangle is a major triad, an inverted triangle a minor, a quadrilateral a dominant seventh. Music's secret was written in mathematics all along.
About This Work
Pythagoras discovered the relationship between intervals and mathematical ratios. Twenty-five hundred years later, Chord Geometry lets you see this discovery's shape. Twelve notes are distributed evenly around a circle like hours on a clock face. Select a chord and connecting lines appear automatically - a major triad forms an isosceles triangle, a minor triad its mirror image, a dominant seventh an irregular quadrilateral. Every chord has its unique geometric signature. Click the keyboard below and the chord sounds instantly. The shape you see is the harmony you hear.
