Music ed curricula already define ear training exercises by type, difficulty, prompt, and answer. Editors record the prompt audio once per exercise, host the files in a CDN, and add one row per exercise to a sheet with the prompt URL, the answer text, and choices.

Multiple-choice exercises carry a choices JSON array per row. Open-response exercises leave the array empty and rely on a conditional selector mapping that swaps the choice list for a text input. The answer text reveals on click in both cases.

Progress tracking lives in the browser via localStorage by default. The exercise pages emit a slug attribute the tracker reads, and the corpus stays anonymous. A logged-in extension could write progress back to a user profile if needed.

Each page carries a unique exercise name, a unique prompt audio, a unique answer, and unique choices. The shared structure is the template, not the content. Search engines treat individual exercise pages as distinct entities.

Set cache duration to 86400 seconds. Exercise definitions rarely change once published, and the cache duration only matters when an editor re-records a prompt audio or corrects an answer. Manual flushes via wp rewrite flush handle the urgent case.

Yes. SleekRank supports JSON file, CSV, Google Sheets, REST API, custom post types, and SQL queries as data source types. A music school could feed the page group from its own LMS while an independent teacher maintains a sheet of canonical exercises.

Add an exercise_type column with values like interval, chord, progression, melodic_dictation, rhythmic_dictation. Add a difficulty column with values like beginner, intermediate, advanced. Sibling page groups render per-type and per-level hubs.

Edit the prompt_audio_url for the row. The next cache refresh rebuilds the page with the new recording and Search Console picks up the updated lastmod. The URL stays stable so external links from course pages continue to resolve.
