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.
