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.

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.

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.

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.

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.

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.

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.

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.

Fork of Blank Slate with Hot Reloading

This interactive rectangle piano renders a 14-key keyboard with white and black keys using raw HTML, CSS, and JavaScript, without relying on external libraries. The visualization demonstrates DOM manipulation and event handling, as clicking each key triggers a Web Audio API `AudioContext` oscillator that plays a sine wave at a frequency mapped from a MIDI note number. The interface provides visual feedback by darkening keys on mousedown, and uses absolute positioning with a repeating seven-key pattern to place notes. The gradient background, responsive layout, and key styling are all achieved through inline styles and CSS.
