This interactive piano visualization uses React to render a two-octave keyboard with SVG, where each key is colored in a distinct pastel rainbow hue based on its note name. Clicking a key triggers a short synthesized sine wave tone via the Web Audio API, creating aural feedback as the key visually brightens for 300 milliseconds. The interface combines playful color coding with functional sound generation, demonstrating a simple musical instrument built entirely with standard web technologies.

Rainbow Piano

This interactive piano visualization uses the Web Audio API to synthesize tones and features a colorful gradient background transitioning from teal to magenta. The piano displays both white keys and black keys, where the white keys are labeled with keyboard letters (A, S, D, F, G, H, J, K, L) alongside note names. Each key responds to mouse clicks and touch events, changing color and shifting downward when pressed. A button above the controls plays a pre-programmed melody, while the audio context is created dynamically on interaction.

Fork of Rainbow Piano

This interactive visualization presents a two-octave piano keyboard rendered in SVG, with each white key colored in a distinct pastel rainbow hue. Users click individual keys to trigger a short synthesized sine wave tone, created through the Web Audio API's `createOscillator` and `createGain` nodes. Pressed keys temporarily darken via CSS transitions and React's `useState`, visually confirming the note selection. The layout maps 24 notes (C1 through B2) to specific frequencies, displaying numeric solfège labels on each key.

Fork of Rainbow Piano App

A playful piano visualization combines realistic instrument styling with sound synthesis. The interface shows a rainbow-colored keyboard with white and black keys, featuring gradient, hover, and press effects alongside a decorative cat figure. Built with HTML, CSS, and the Web Audio API, it dynamically generates keys via JavaScript and triggers tones on click. CSS flexbox, transitions, transforms, box-shadows, and clip-path create the visual depth, while the audio context handles note synthesis.

Fork of Fork of Rainbow Piano

A piano keyboard rendered as a colorful SVG interface lets users play notes by clicking keys, with each key displaying its corresponding solfège number. The React app maps 24 notes to specific frequencies and uses the Web Audio API’s `OscillatorNode` and `GainNode` to generate short sine-wave tones. Each white key is filled with a pastel rainbow color based on its note letter, while pressed keys temporarily brighten or darken. The layout includes both white and black keys, with black keys positioned between the white ones at higher vertical offsets.

Rainbow Piano App

A Rainbow Piano App renders a virtual, interactive piano with both white and black keys. The visualization demonstrates realistic 3D effects through CSS gradients and shadows, while allowing playback through mouse clicks, touch events, or keyboard shortcuts mapped to specific notes. The built-in demo melody plays a simple scale, with audio synthesis generated via the Web Audio API and visual feedback provided through CSS transitions on key presses.

Rainbow Piano App

Rainbow Piano App is an interactive virtual piano that generates musical tones through a Web Audio API, playable via mouse clicks, touch events, or computer keyboard mappings. The visualization presents a gradient-styled keyboard with animated key presses, where white keys respond to letter keys A through semicolon and black keys map to W, E, T, Y, U, O, and P. A demo melody button triggers a pre-recorded sequence. The interface uses DOM manipulation with CSS transitions for a smooth, responsive design across different screen sizes.

Piano App

This interactive piano app renders a two-octave keyboard as an SVG, where clicking a key triggers a sine-wave tone. The React component manages a set of pressed keys, updating their visual state, while the Web Audio API's `createOscillator`, `createGain`, and `exponentialRampToValueAtTime` methods synthesize a short, fading note. The white and black keys are drawn as SVG rectangles with note labels, and the app uses CSS transitions to show a subtle press effect.

Sunset App

This visualization shows an interactive piano with colorful gradient keys and a decorative gray cat. The code uses the Web Audio API to synthesize sounds and JavaScript for dynamic key generation. CSS flexbox arranges the keys, while transitions and transforms create hover and press effects. CSS gradients, box-shadows, and clip-path define the piano’s styling and the cat’s ears, with event handlers triggering audio feedback on key interactions.
