Brief

The canvas displays a single, visible circle positioned within the frame. The sketch is inactive until the user performs a click, which initializes a tone. From that point, the primary interaction involves dragging the circle vertically. As the user drags the circle up and down, the physical vertical position of the circle directly controls the pitch of the continuous tone, making the sound rise when the circle moves upward and fall when it moves downward.

Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited

This sketch creates an interactive audio visualization where a blue circle can be dragged vertically to control the pitch of a continuous sine wave tone. The circle's vertical position directly maps to frequency — moving it upward raises the pitch from 440Hz to 880Hz, while moving downward lowers it. The interface responds to both user clicks to initialize audio and drag gestures to adjust pitch. A visual reference line indicates the pitch range, making the relationship between physical motion and sound clear. The implementation uses p5.js's built-in oscillator and mapping functions to create a responsive audio-visual feedback loop where the viewer can hear pitch changes as they manipulate the circle's position.

The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.
