Learn to read sheet music over various clefs!

Practice reading and inputting notes using your finger, plugging a piano keyboard in, or virtually any other instrument using the microphone input mode.

Take your skills outside of the app: Clef Trainer Grid also features a special grid input that scrambles button locations to prevent the building of a muscle memory. This ensures that you're actually learning the note letters, rather than just learning how to use an app!

Still want to learn the piano keys? No worries! You can also switch a classic piano input at any time.

Features also include:

* Support for treble, alto, and bass clefs

* Support for every major and minor key signature

* Support for accidentals—Choose if you want to play outside of the key!

* Adjustable number of ledger lines

* Cheat Mode—View the names of the notes in real-time!

* Dark Mode

* Ghost Note —View miss-input notes on the staff
