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.

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 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.

Piano App

An interactive virtual piano with white and black keys generates musical tones through the Web Audio API, allowing play via mouse, touch, or keyboard. The instrument displays a realistic 3D design using CSS gradients and shadows, with visual feedback through CSS transitions on key presses. A built-in demo melody button triggers a pre-programmed scale. The implementation dynamically creates piano keys through DOM manipulation and uses Web Audio API for audio synthesis with gain control, demonstrating front-end techniques for responsive instrument interfaces.

Rainbow Piano

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.

Sequencer

This interactive music sequencer combines a piano keyboard with an 8-step programming grid for composing rhythmic patterns. The interface displays a grid where users toggle cells to activate notes and adjust playback tempo, while playback animates a highlight moving across the steps. React manages the application state and handles user interactions, while SVG renders the grid and keyboard with dynamic colors indicating programmed notes versus currently playing ones. The audio component generates sine wave sounds in real-time through the Web Audio API, creating immediate auditory feedback for each programmed step.

Fork of Piano App

This interactive piano visualization renders a stylized keyboard with white and black keys, complete with gradient styling, hover effects, and a decorative cat figure seated in front. The piano generates sound through the Web Audio API, with each key press triggering synthesized tones via JavaScript event handling. The layout uses CSS flexbox, transitions, transforms, and clip-path shapes to create realistic proportions and depth, while dynamic key generation builds the interface programmatically.

Arc Piano

The visualization displays a semicircular piano keyboard whose keys extend outward when hovered or touched. It uses a D3 pie layout for the key positions, with custom arc tweening via `transition.attrTween` to animate the radial expansion. The code generates audio tones using the Web Audio API's `createOscillator` and `createGain` nodes, playing a square wave at a computed frequency for each key. The SVG rendering uses D3's `d3.arc` with corner radii and two inner-radius levels to distinguish sharp and white keys.

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.
