Movable-do, done properly.
Most tools stop at a stave. NoteFusion derives every syllable from the key it detected, making the notation immediately singable for choirs and vocalists who read Tonic Solfa.
- Doh follows the key across all 24 keys, major and minor.
- La-based minor mode: A minor reads l t d with Doh naturally anchored on C.
- Proper chromatic syllables: Sharp and flat notes get their true vowels: de, ra, fe, se, ta.
- Octave marks included so pitch registers are unambiguous to rehearse from.

Frequently asked questions
Do I need to read music to use NoteFusion?
No! That is the core benefit of Tonic Solfa. If you can hum or sing doh, re, mi, you can read and teach what NoteFusion gives you immediately. The staff notation is included for instrumentalists or choir directors who prefer standard notation.
How accurate is the transcription?
A clear solo vocal line, hummed melody, or single acoustic instrument in a moderate room yields 90%+ confidence. Every transcription comes with a confidence score so you always know what to review.
What happens to my voice recordings?
Your audio is transcribed and then permanently deleted from our servers immediately after the ML worker completes. No person listens to your recordings, and your audio is never stored or used to train third-party models. See our privacy policy.
Can I change the key after transcribing?
Yes, and it is 100% instant. Re-keying is a pure musical re-labelling: Doh updates to the new pitch without re-analyzing or altering the audio fidelity.
Who owns my transcriptions and notation?
You own everything you transcribe. Your library is encrypted and private to your account. You can export your sheet music as MusicXML or PDF whenever you choose.
How can I permanently delete my account or data?
You can delete your account and all data at any time from within the mobile app (Settings → Account → Delete Account) or directly through our public web portal at notefusion.studio/delete-account.
