Sight Reader: Treble Clef

Learn to read piano notes on Android, one note at a time.

Sight Reader turns real sheet-music reading into a game you'll actually want to practice. Whether you're a complete beginner or brushing up before lessons, build genuine note-reading fluency across the full grand staff - treble clef and bass clef, ledger lines and all.

The Musician's Journey world map

Sight Reader builds real sight-reading fluency the way music teachers actually teach it - starting from landmark notes near Middle C, then expanding step by step into ledger lines and the full range of the keyboard. Every session adapts to what you've actually mastered, so you're always working right at the edge of your current skill. See the privacy policy for details on data handling - notably, microphone audio is analyzed on your device and never transmitted anywhere.

Musician's Journey

A guided campaign that introduces notes gradually across the grand staff, unlocking new landmarks as you progress. Daily streaks, combo scoring, and a lifetime XP and title system reward real practice, not just app opens.

Custom Practice: Reading and Writing

Pick your own clef, note range, and pool size, and drill exactly what you're working on. Reading mode shows you a note and asks you to name it; Writing mode does the reverse - hear a note name and place it correctly on the staff - training both directions of music literacy. Once unlocked, practice any of 13 major keys, with sharps and flats notated the way real sheet music does it, not just the white keys.

Play your way

Answer every note by tapping the on-screen keyboard, note circle, or the staff itself - fast, reliable, and works anywhere, no setup needed. Have a MIDI keyboard? Connect it for direct input. Sight Reader can also listen through your microphone and recognize notes played on a real piano or keyboard - a nice bonus for practicing away from the screen, processed entirely on-device and never recorded or uploaded.

Survival & Time Attack

Once you've mastered enough notes, fast arcade-style rounds turn practice into a real challenge, with combo scoring and a run history - a quick way to test what's actually stuck.

Free to start, one-time unlock

Try the first octave of each clef completely free, across every mode - no time limit, no ads, ever. Unlock the full note range with a single one-time purchase whenever you're ready. No account, no subscription.
