The on-screen keyboard
Played with your finger: the tablet is enough, even on the go.
A domain of the path
Low C, the five notes up to G, the bass octave, the way up to middle C, leaps, sharps and flats, all the way to the key signature. Your left hand learns to read like your right.
With the subscription. Free: keyboard discovery and the start of the treble clef.

What you'll learn
The bass clef sits on the fourth line of the staff: its two dots frame that line, and the note on it is an F. It's the clef of the low notes, the ones your left hand plays.
Okyla starts from low C, climbs the five notes up to G, plays the bass octave, then heads back up to middle C, where the two clefs meet. After that come leaps, sharps, flats and the key signature in the bass clef.
If you've already learned the treble clef, the path will feel familiar: the same stages, with different landmarks.
The exercises
In the order the app offers them.
Interactive tutorials
Read the three signs in bass clef
Read a key signature on the bass staff
Each exercise comes in several sequences: “Redo” the same one, or “New sequence” to play another.
What to play on
In Guided mode, the piano waits for you if you slip; in Performance, you play in tempo.
Played with your finger: the tablet is enough, even on the go.
Put the tablet on the music stand: Okyla listens through the microphone, and the sound never leaves the device.
Plugged in over USB, every note is read the moment you play it.
Find F: it's the note on the fourth line, between the clef's two dots. On the lines, from bottom to top: G, B, D, F, A. In the spaces: A, C, E, G. Middle C sits just above the staff, on a small added line.
No. The bass clef reading exercises can also be played with your finger, on the on-screen keyboard. With a piano, Okyla listens through the microphone; with a digital keyboard plugged in over USB, every note is read the moment you play it.
In the path, both come right after keyboard discovery. Most pianists start with the treble clef, the right hand; the order is up to you.
The bass clef needs the subscription. Keyboard discovery and the start of the treble clef are free.
