Start practicing →Know notes on sight
Counting up the lines works, but it's slow. Trebly starts from two landmarks: G, where the treble clef curls, and middle C, on its own short line. Then the lines and spaces become easy patterns.
Learn the treble clef →Your weak notes come back
Trebly keeps track of every answer. Notes you miss or answer slowly come back sooner, and notes you know well step aside. Your practice time goes where it does the most good.
Try Training →From notes to songs
Name each note of a familiar tune and hear it come together as you go. Get one wrong and it simply comes back around. Then keep a beat in Pulse, and write down what you hear in Dictation.
Browse the songs →Read it. Write it. Hear it.

I used to be a musician. Reading music felt like a chore that stood between me and the music.
Questions
Is Trebly free?
Yes. The lessons, practice modes and guides are free to use, with no account or sign-up.
Do I need an instrument?
No. Everything happens on screen: you name notes by tapping, clicking or typing, and Trebly plays the sounds for you. If you do play an instrument, your reading will carry straight over.
Does it work on a phone?
Yes. Trebly runs in any modern browser on a phone, tablet or computer. On a computer, you can answer with your keyboard too.
Where is my progress saved?
In your browser, on your device. There’s no account, so progress doesn’t move between devices. See the privacy page for details.

The treble clef from middle C up to the G above the staff, which is the range most beginner music uses, plus rhythm, note lengths, measures and basic ear training.
