  "brief": "The canvas presents a depiction of a guitar fretboard ready for playing. As the user drags the mouse across the canvas, the movement triggers a musical tone. The position and speed of the drag dictate the pitch and quality of the sound, making the drawing a responsive instrument. This interaction provides a continuous, audible feedback that directly correlates with the user's physical input, allowing the viewer to musically interact with the artwork.",

  "statement": "This sketch transforms a guitar fretboard visualization into an interactive musical instrument. When a user drags their mouse across the canvas, the movement triggers tones whose pitch is determined by vertical position and whose quality (volume) is controlled by movement speed. The interface provides both visual feedback through drawn lines and circles, and audible feedback through sine wave tones generated in real-time. The interaction maps physical motion directly to musical expression, creating an intuitive and immediate connection between gesture and sound. The design uses a simple but effective mapping where faster movements produce louder sounds, and higher positions on the fretboard generate lower pitches, mimicking the natural relationship between string position and pitch in guitar playing.",
