Journey
After 9 Foundations lessons, the Journey splits into 6 branches you can explore in any order. When one lesson is hard, another is always open.

New to notation or already reading? Pick one of 4 starting points. Lessons below your level count as done, and their stars are still yours to earn.
A lesson unlocks once you clear what it needs with one star. Locked lessons list exactly what is missing, and the map suggests what to play next.
One star means you read it correctly. Two means at the target tempo. Three means fluently, across several fresh lines.
The Daily Mix is 4 minutes of practice built from the skills due for review. Checkpoints and capstones mix whole branches and tiers.
Level Assessment
Trained on thousands of classical works from PDMX, it composes musically correct pieces at exactly the difficulty you need and adapts to your skills as you play, pushing you just past your comfort zone and into flow.
Your result is a Grade, a rating and a confidence range. Grade is SightFlow’s own scale of sight-reading difficulty, not an exam board grade. Roughly, a Grade 3.0 means you have about a 70% chance of reading an ABRSM Grade 3 piece at first sight.
One real piece for every point of the chart, written by the same model that runs in your browser. Pick one and read it.

Unedited output of the Assessment model, graded by SightFlow and engraved by the same notation engine as the app. Your own exam writes new pieces every time.
Feedback
Built for the details that decide whether you can read in real time.
Notes light up the moment you play them, so you see what landed and what did not without stopping.
Know whether it is the note or the beat that slips, with your average timing bias shown in milliseconds.
Slows down when a passage is shaky and speeds up once it is secure. You stay challenged, never stuck.
Vanishing notes fade the music ahead of the playhead, pushing you to read ahead instead of note by note.
Illustration: one pass through eight notes, read four ways.
Metronome patterns, adjustable playhead and a built-in piano sound

FAQ
No. You can play on your computer keyboard or the on-screen piano. A MIDI keyboard gives the most natural experience, and MIDI input depends on your browser supporting Web MIDI.
No. SightFlow works as a guest and keeps your progress in your browser. Sign in with Google or an email link if you want your progress synced across devices.
Yes. SightFlow runs fully in your browser on desktop, tablet and phone, so there is nothing to install. Native Android and iOS apps are coming soon.
Yes. Journey begins at Middle C and introduces the staff, rhythm and both hands one small step at a time.
No. When you open Journey, pick the starting point that matches you, from new reader to intermediate. Earlier lessons are marked as done, so their branches open right away, and you can still go back to earn their stars. The Daily Mix brings their skills back early to check they hold up.
You play a series of pieces, one attempt each. A neural network trained on classical music composes every piece at the difficulty of your current Grade, and your estimate is updated after each performance. Your pitch, rhythm, continuity and completion add up to a final Grade with a confidence range. It is part of Pro.
No. Grade is SightFlow’s own scale, calibrated for how hard a piece is to read at first sight rather than how hard it is to perform after practice. As a rough guide, a Grade of 3.0 on your profile means you have about a 70% chance of reading a piece at ABRSM Grade 3 difficulty at first sight. SightFlow is not affiliated with or endorsed by ABRSM.
Importing MusicXML, MXL and MuseScore files is part of Pro. Imported scores stay in your browser and are not uploaded or synced.
Free practice is limited to 15 minutes a day. Pro removes the limit.
