Clefle
From the staff to your fingers
Most note-reading apps stop at the name. Clefle also shows you which string and which finger, so reading turns straight into playing.
Note reading for violinists
Read notes as fast as you read words
A few minutes a day on a real staff. Name the note, find it on the fingerboard, then play it while Clefle listens. For adults teaching themselves, and for kids just picking up the violin.

What makes it different
It listens to your violin
Play a note and Clefle hears whether it's the right one, and how many cents sharp or flat. The sound is analysed on your device and never sent anywhere.
C D E or Do Re Mi
Use letter names or fixed Do — whichever your teacher uses. No account, no email, nothing to install. Add it to your home screen if you like.
How a new note is learned
Every note goes through four steps, in the order people learn a language: hear it first, then see it, then point to it, and only then produce it.
- Hear A recorded violin, not a synthesised beep.
- See Where the note sits on the staff.
- Point Find it on the fingerboard: which string, which finger.
- Play Play it on your own violin while Clefle listens.
Ten levels, from the staff and a few landmark notes to reading whole phrases and rhythms. Clefle remembers which notes trip you up and brings them back just before you'd forget them.
Questions
Is it free?
Yes — everything is free right now, with no ads.
Do I need a violin?
Not to start. Reading notes, finding them on the fingerboard and listening only need a phone or computer. The play-along part needs a violin and a microphone.
Is it good for kids?
There's a kids' mode with bigger text, a little bird companion, short sessions and no percentage scores — just a progress bar and a few stars. Children who can read will follow along; younger ones do best with a parent beside them. A parents' page shows how the week went.
Where is my data stored?
On your own device. There are no accounts, so nothing is sent to a server — not even the sound from your microphone. Clearing your browser data clears your progress too, so there's a button to save it to a file.
Does it teach piano or guitar?
Only violin for now. Piano, guitar, saxophone and drums are planned.
