# Harp strings

> The strings of a harp vibrate with real wave physics when the pointer crosses them and glow brighter the harder they ring, on canvas.

## Where to use it

A concert harp you can play with the pointer. Every string is a small one dimensional wave simulation with fixed ends, so crossing it plucks a triangle shape that splits into travelling waves and slowly dies away. Shorter strings vibrate faster, just like higher notes, and the curved neck and base frame the whole instrument. When nobody plays, a breeze plucks a string now and then.

The first and second colors run across the strings from gold to copper, and the third is the glow of a ringing string. Density sets how many strings there are. Lovely for music schools, concert halls, sound design and calm portfolio intros.

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “Harp strings” block (Backgrounds) from AIMRAN Library to my project.

## What it is
The strings of a harp vibrate with real wave physics when the pointer crosses them and glow brighter the harder they ring, on canvas.

## Chosen settings
- Color 1: #d4a020
- Color 2: #9a4f1c
- Color 3: #ffcf6e
- Speed: 1x (from 0.2 to 3x)
- Density / scale: 1x (from 0.5 to 2x)
- Opacity: 1 (from 0.2 to 1)

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
