tabsaur.us

What It Is

Tabsaurus is a JavaScript library from Better Notes, LLC for pages that display guitar tabs, chord charts, and lyrics. It scans <pre> elements—or elements with specified IDs/classes—and converts plain-text ASCII tabs into richer, better-looking notation, placing chords above the lyrics and keeping the layout readable on narrow mobile screens.

Core Features

Feature-wise, it supports chord recognition, ChordBank chord-diagram hover popups, custom chord definitions, displaying chord diagrams at the top, transposition, font-size levels, style overrides, and—starting from version 1.1—tab-line rendering features including hammer-ons, pull-offs, slides, vibrato, bends, muted notes, bar lines, and basic note values. The API is very simple: include tabsaurus.js via a script tag, then call tabsaurus(options). Configurable options include the target element, transpose, diagrams, tabs, bg, style, size, and more. The documentation provides a good range of examples covering common integration and display needs.

Pricing and Licensing

The main text does not describe commercial pricing or paid plans. Instead, it states that the library can be used permanently on websites, including commercial websites, but must comply with the Creative Commons Attribution-NoDerivatives 4.0 International License. This license allows use, but the “NoDerivatives” clause may limit modification and redistribution. The text does not mention an npm package, source repository, or self-hosting method; it only provides an HTTPS-hosted script URL from tabsaur.us.

Pros and Cons

Its strengths are the low barrier to integration, small footprint, and strong focus on music-notation use cases. It significantly improves the mobile readability of traditional plain-text tabs, and ChordBank helps fill in chord-diagram coverage. The downsides are that the latest changelog entry dates back to 2018, so maintenance activity is unclear; it depends on an externally hosted script and ChordBank; and it lacks TypeScript support, modular builds, frontend framework integrations, and complete engineering documentation.

Who It’s For and Access from China

Tabsaurus is suitable for guitar-tab websites, music education sites, lyric-and-chord pages, and developers who want to quickly offer transposition and chord-diagram hints. It is less suitable for teams that require heavy customization, offline deployment, or deep integration with a modern frontend toolchain. The source text provides no information about access from China, so the connectivity of tabsaur.us and ChordBank, as well as payment methods, cannot be assessed. Alternatives to consider include VexFlow, AlphaTab, OpenSheetMusicDisplay, and abcjs.
