Tools FAQ
- Does the metronome work offline?
- After the page loads once, many browsers keep it running without a connection for practice sessions — refresh if assets fail to load.
- Does the microphone tuner need permission?
- Yes. Your browser prompts for mic access so we can analyze pitch. Reference-tone mode works without a microphone.
- How accurate is key-from-chords?
- It ranks major keys by how many chord roots fit diatonic to each key. Ambiguous short progressions may tie several keys — use your ear or add more chords.
- Where do Roman numerals come from?
- They describe scale degrees in the selected major key. Pair this hub with Chord construction and Nashville numbers if symbols are new.
- Does the drum machine use samples or need a download?
- No. Every groove is synthesized in your browser and loops gaplessly, so the drum machine loads instantly, uses no audio files, and works offline once the page has loaded.
- Are these tools free?
- Yes. No account or subscription — open the tool you need and practice.
