Something appears on the stave — a note, an interval, a chord or a whole scale. Name it, and get instant feedback with a running score. Treble or bass clef, from the five staff lines out to two ledger lines each way.
The staff is five lines and four spaces. A clef fixes which pitch each line is: the treble clef curls around the G line (second from the bottom), the bass clef's two dots sit either side of the F line (second from the top). From that one anchor, every other note is a step up or down.
Treble lines, bottom to top, are E–G–B–D–F; the spaces are F–A–C–E. Bass lines are G–B–D–F–A; the spaces are A–C–E–G. Middle C sits on a ledger line just below the treble staff and just above the bass staff — the two clefs meet there.
Drill until it is instant. The goal is not to work out each note but to recognise it the way you recognise a letter. Pair this with the Fretboard Trainer or a keyboard so you connect the symbol to a sound and a position. The Cloud Atelier guides have a full lesson on notation.
Reading a score is not note-by-note spelling — it is recognising groups. The Interval, Chord and Scale drills put two, three, four or eight notes on the stave at once and ask what they are. Every accidental is written in, so a diminished seventh really reads C–E♭–G♭–B♭♭ and a Lydian scale really carries its raised fourth. That is the step between naming notes and reading music. Build the same shapes with your hands on the Keyboard Trainer, hear them on the Chord & Scale Ear Trainer, and work through the theory in order on the Music Theory Fundamentals path.
