# TabShare

> TabShare is a playability-first guitar and bass tab product. The public site at https://tabshare.live is a Next.js prototype: ChordPro charts are real, the studio player is a demo/synth arrangement, and Create can run a stem worker pipeline when configured. Automatic music transcription does not run inside Vercel request handlers. There is no teacher-approval program and no published quality metrics.

TabShare’s thesis is real: a note is not a fingering. The product should map music onto human hands, then give players a synchronized practice surface. That positioning is the product, not a claim that the full audio-to-tab engine or mix separation is finished.

What this site is:
- A marketing and product-thesis surface for human-playable tabs
- A public ChordPro catalog with interactive lead-sheet viewers
- A studio player prototype for an original demo (“Signal Fire”)
- A Create flow that can store a source file and, with a worker, process guitar/bass stems through transcription, fretting, playability validation, and engraving

What this site is not:
- A finished transcription platform or mix-separation product
- A teacher marketplace, certified-lesson network, or scored practice academy
- A claim that every upload becomes a playable tab, or that results are artist-authoritative
- A path from Create to the Signal Fire demo score

Create honesty: ingest stores a file when Vercel Blob is connected (or issues a local-only receipt). Stem jobs queue a worker when `TABSHARE_WORKER_URL` is set; otherwise they fail honestly. Mix jobs report that separation is not ready. The UI never treats the studio demo as the user’s result. A playable badge requires zero hard physical violations.
