A clean music theory chord catalog is straightforward to author in a sheet. Editors define each chord type once with notes, intervals, guitar fingerings, and piano voicings in JSON columns. The catalog transposes across all 12 keys via a script, then SleekRank reads the rows.

F sharp major and G flat major are the same chord with different spellings. Each spelling carries its own slug row, and the notes array reflects the preferred spelling per row. A cross-link in the related strip surfaces the enharmonic equivalent so readers find the right page.

Extended chords like Cmaj9, Cm11, and C13 live in their own rows. The notes array carries the full chord tones, the intervals array carries the extended pattern, and the guitar fingerings JSON typically carries voicings that drop the fifth or another tone.

Each page carries a unique root, a unique chord type, unique notes, unique intervals, unique fingerings, and unique audio. The shared structure is the template, not the content. Search engines treat individual chord pages as distinct entities.

Set cache duration to 86400 seconds. Chord definitions rarely change once published, and the cache duration only matters when an editor corrects a fingering or adds a new shape. Manual flushes via wp rewrite flush handle the case where editing needs to be live.

Yes. SleekRank supports JSON file, CSV, Google Sheets, REST API, custom post types, and SQL queries as data source types. A music education startup could feed the page group from its own theory engine while a smaller blog maintains a sheet.

Add a root column and a chord_family column with values like major, minor, dominant, diminished, augmented, suspended. Sibling SleekRank page groups read the same source filtered by root or by family and render per-root and per-family hubs.

Edit the guitar_fingerings JSON for the row. The next cache refresh rebuilds the page with the updated fingering and Search Console picks up the updated lastmod. The URL stays stable so external links from songbooks continue to resolve.
