Question 1

Why does a major triad look smooth and a tritone look jagged?

Accepted Answer

Consonance and dissonance are visible properties of the resulting waveform. Consonant intervals produce waves that repeat cleanly over a short period, so a major triad draws as a smooth, regularly repeating shape. Dissonant intervals such as a tritone produce waves whose period is long or irregular and never quite closes, so the shape looks jagged. ChordSine makes that difference visible.

Question 2

What is ChordSine?

Accepted Answer

ChordSine is a free, browser-based chord waveform visualizer designed like an instrument, not a graph. You play notes and chords, switch between individual wave components and their sum, and watch the repeating period in real time, so you can both see and hear the shape of the music. The free playground is called Sinescope.

Question 3

Do I need to know music theory to use ChordSine?

Accepted Answer

No. ChordSine is an instrument, not a course. You explore freely by playing notes; the visualization reveals the relationship between sound and shape directly.
