## What it is
alphaTab is a cross-platform music notation and guitar tablature rendering library available for JavaScript, .NET, and Android. It loads scores from formats like Guitar Pro, MusicXML, and its own alphaTex markup, renders them as SVG or raster graphics, and can play them back via a built-in MIDI synthesizer.

## Use cases
- render guitar tablature on a website
- display music notation from Guitar Pro files in the browser
- build an online sheet music viewer and player
- embed interactive music scores in a web app with playback
- parse MusicXML files into a renderable score
- show drum tabs and standard notation side by side
- add a tab player with cursor sync to a music lesson site

## When to choose
- you need to embed feature-rich music notation or guitar tabs into a website or app
- you want to support Guitar Pro, MusicXML, and a text-based notation format from one library
- you need audio playback of scores with a built-in synthesizer across web, .NET, or Android
- you want responsive, resizable music sheet rendering as SVG or canvas

## When to avoid
- you need a ready-made, drop-in sheet music component with no development effort
- you need engraving-quality print output comparable to dedicated notation software like MuseScore or LilyPond
- your project is native iOS or another platform without an officially supported flavor
- you only need simple MIDI playback without visual notation rendering
