CLUSTER TRANSPOSES-WEB-CHORD · 13 ENTRIES · EARLIEST ENTRY 2025-08-21

Chord transposition and songbook tools

This cluster consists of web tools for managing personal songbooks of chords and lyrics, with features like transposition, search, tagging, and auto-scroll, as well as dedicated chord transposition tools. The dated history is too thin to read a shape from – only four dated entries exist before the index start, and most members lack source dates. All traction leaders show zero stars, so no product stands out on activity.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
