Barre-free guitar voicings, borrowed chords and playable progressions
Open Shape is a personal guitar web app for exploring alternate chord shapes, borrowing chords from other modes and sketching progressions with synthesized playback. What works today Voicing search across 12 roots and seven chord qualities, with position filters and SVG chord diagrams. Shapes designed around separate fingers, a four-finger maximum and consecutive sounding strings. Fingerings are suggestions; comfort varies by hand. Borrowed-chord explanations, example sequences and links to matching shapes. An editable 2-16-slot progression builder with tempo, chord lengths, looping and an exact chosen number of borrowed-chord slots. The app uses ordinary HTML, CSS and JavaScript and needs no paid model API or application subscription. It can run on static web hosting or a local web server. Build and current status Built with substantial AI assistance. All 19 existing automated checks passed on the sale snapshot. A focused desktop browser check covered the three modes and progression generation; universal device compatibility and accessibility conformance have not been established. Pre-revenue: US$0 revenue. No verified audience, paying customers or growth results are claimed. The buyer would handle user testing, hosting, further development and commercialization. User accounts, billing, subscriptions, analytics and saved-user data are not implemented. What transfers The proposed exclusive sale covers the seller-controlled source files, local preview server, README, automated checks, setup/review notes and screenshots, subject to a final written asset agreement and owner approval. Third-party licences remain separate. No domain, hosting/Cloudflare account, customer records, social account or registered trademark is included. Optional Google Fonts references use DM Sans and Manrope, with system-font fallbacks; font files are not bundled. The protected hosted demo and source are kept private. Price and handover Asking US$2,500, negotiable. No automatic checkout or auction. The owner approves sale terms and handles payment. Setup notes and a proposed one-hour remote handover can be agreed at sale; ongoing support and development are separately negotiated. The project is offered to a buyer interested in further development and distribution, for example as a guitar practice aid or part of a music-education product. No monetization results are promised.
