Whole-study overview

Ready. Four voices enabled.

The subject

One idea enters.

Listen for the opening line. Its shape gives the other voices something to remember, repeat, and answer.

I / SopranoA contour to remember.
The answer

The idea finds
another voice.

The alto enters later, carrying the shape into a different register. Follow the offset between the two lines, and the answering shift in the page’s columns.

I + II / Subject and answerA new entrance. A familiar shape.
Together

Four voices.
One shared time.

Each line follows its own path. Hear how their independent movements meet on the same pulse. The layered graphic keeps all four contours on one precise grid.

I + II + III + IV / CounterpointSeparate lines. A common pulse.

About the study

This is an original synthesized illustration inspired by Bach’s contrapuntal language. The four voices share a repeating subject with staggered entrances and changes of register.

The page follows the same structure. A regular time grid holds independent voice lanes. The answer shifts the visual hierarchy, and the final chapter brings the layers together. Scroll to trace each entrance; play to see accents follow the audible notes.
