## What is Clef Trainer Grid?

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

## Key features

- Treble, alto, and bass clef support

### 5/5 — well made little app

*2026-04-12*

helps with sight reading especially if rusty

### 3/5 — Bare bones app

*2026-03-25*

Honestly I’m being very generous by rating it 3 stars since it is extremely limited right now. There is not much here to justify the £3 price tag when the value feels more like it should be 99p at best. What I would like to see in future is the ability to practice to some royalty free classical music, create or upload your own music sheets to practice to, and also practice some other aspects of sight reading like rests, chords, tempo changes, staccato ect… (Maybe also add difficulty levels or for us to create sheet music and share it for other people to practice too.) I hope the developer keeps working on this :)

### 5/5 — Bluetooth MIDI

*2026-01-21*

Great app! But I would just appreciate it if you could add a Bluetooth midi feature to connect my Bluetooth supported piano with midi

### 5/5 — download it !!!

### 5/5 — Very useful learning tool

*2025-08-12*

I am very new to sight reading so this app is such a great way to practice! It’s super simple to use. I especially love that it plays the notes after you guess correctly. And I love the different methods you can use to input the notes. 6/5 stars ⭐️🎼🎹
