Seven Ways the Quartet Connects
A guided tour through the ideas behind the piece. Each step pairs an interactive visualization with directions and context. If the quartet is playing, it will continue — use the player at the top while you explore.
A Visual Companion to the flute quartet of the same name, by Robert Rabinowitz
Watch the film, listen to the quartet, then take a guided tour through seven interactive visualizations — audio keeps playing while you explore.

How to interact: Click and drag any of the four colored spheres within the 3D space using your mouse or finger. As you move one sphere, watch how the others respond with changes in their size, color, and rotation. You can also click and drag in empty areas to rotate the camera view around the scene, use the mouse wheel or pinch gestures to zoom in/out, and right-click with drag (or two-finger drag on touchscreens) to pan the camera.
What it shows: This demo visualizes how parameters in the quartet are interdependent through cubic, bounce, and sine-based transformations. Each sphere represents one of the four flute voices, and their responses mirror how in the piece, when one flute introduces a musical element (represented by dragging a sphere), the other three respond with distinct yet mathematically related transformations.
How to interact: Click and drag any of the four torus (ring) shapes in the 3D space using mouse or touch. Notice how the effect cascades through the other elements with varying intensity. When not actively dragging, the objects will perform subtle orbital motions around their original positions. You can also click and drag in empty space to orbit the view, use mouse wheel or pinch gestures to zoom, and right-click with drag (or two-finger drag on touch devices) to pan the camera.
What it shows: This demo illustrates how musical events in the quartet cascade through the four flutes with varying intensity based on their musical "distance." Using sine, exponential, and circular interpolation functions, the transformations diminish proportionally to how "far" an element is from the one you're manipulating.
How to interact: Click and drag any of the four geometric shapes (octahedron, dodecahedron, tetrahedron, and icosahedron) in the 3D space using mouse or touch input. Pay attention to how the response of other elements becomes more extreme with certain positions. This demo uses trackball controls — click and drag anywhere to freely rotate the scene, use mouse wheel or pinch to zoom, and hold the right mouse button or use three fingers to pan the view.
What it shows: This demo emphasizes the unpredictable, exponential response relationships in the quartet, where small musical gestures can create dramatic effects. A small movement in one area might produce dramatic changes, while larger movements elsewhere might create subtler effects.
How to interact: Click and drag the white sphere horizontally across the scene using your mouse or touch. Observe how the colored objects move at different rates and follow different paths. Click and drag in the scene to orbit the camera, scroll to zoom, and right-click and drag to pan.
What it shows: This demo contrasts linear interpolation with various non-linear methods. As you move the control sphere, objects follow different mathematical curves — accelerating, decelerating, bouncing, or oscillating. In the quartet, musical transitions are governed by similar complex relationships.
How to interact: Click and drag any of the colored spheres using your mouse or finger. As you move one sphere, watch how the others respond with changes in their size, color, and rotation. Click and drag elsewhere to rotate the camera, scroll to zoom, and right-click with drag to pan.
What it shows: This demo illustrates how the four flute voices function as components of a single, deeply intertwined musical entity. When you move one sphere, the others respond in coordinated ways through specific mathematical relationships.
How to interact: Click and drag any colored node in the matrix visualization. Observe how connections change in strength, brightness, color, and thickness. Click and drag in empty space to orbit, scroll to zoom, and right-click with drag to pan.
What it shows: This demo visualizes the "score" of the quartet – the blueprint mapping dependencies between the four flutes. The glowing lines represent the matrix of interdependencies, with brightness and thickness illustrating relationship strength.
How to interact: Click "Measure A" or "Measure B" to collapse the entangled pair. Use "Reset" to return to superposition. Drag to rotate, scroll to zoom.
What it shows: Two entangled particles in superposition — measuring one instantly determines the state of the other, mirroring how a musical gesture in one flute voice reshapes the context for all voices.
