Reading Music

Every note on the stave, drawn properly — with the mnemonics, the landmarks that replace them, and a trainer that finds out which notes you are slow on.
position, not memory
Treble · C major
Region Global. Standard Western five-line staff notation and twelve-tone equal temperament. Note values are named in British English with the American names alongside, and middle C is called C4, which is a convention some software does not share.

The stave

treble
Treble and bass are not two alphabets. They are one ladder with middle C in the gap between them, and seeing that once is worth more than any mnemonic.

Drill

off
Ledger lines are where reading actually breaks down, so they are a setting rather than an afterthought.
Notes you get wrong or answer slowly come round more often. That is the whole difference between practising and just being tested.

Every note, named

Ways to remember it

Landmarks — what fast readers actually use

A mnemonic is a sentence you recite from the bottom of the stave upwards, and it costs about a second. A landmark is a note you simply know, and everything within a third of it is then one or two steps away. Fast reading is landmarks and intervals; the sentences are scaffolding you are meant to take down.

One note, four clefs

Same sound, four positions. A clef is not a code to crack — it just says which line is which pitch, and everything else follows from the ladder.

How long is it

4/4
NoteNameBeatsPer bar

Each row is half the one above it, all the way down — which is the whole system. A dot adds half the note's own value, so a dotted minim is 2 + 1 = 3 beats.

How it works

A stave is a ladder, not a code

A ladder, not a code

Five lines and four spaces make nine rungs, each the next letter of the alphabet. A note’s height is its letter; a clef names one rung and the rest follow by counting.

The diatonic index

Each note gets one number counting letters, not semitones: C4 is 28, D4 29, E4 30. Treble puts E4 on the bottom line, bass puts G2.

Accidentals move sound, not place

Sharps and flats change pitch without moving position, so a key signature says “every F is sharp” once and the notes stay where they were.

Placed by rule

Sharps run F C G D A E B (flats backwards), each placed by going up a fifth if that stays on the stave, otherwise down a fourth.

Worked example. Each note gets a single number, its diatonic index, counting letters rather than semitones: octave × 7 plus the letter (C = 0 … B = 6). A clef fixes one of those numbers to the bottom line, and every other rung is half a line-space away per step. Both directions run off the end of the stave with nothing special happening, which is what ledger lines are: the ladder continuing. Conventions: scientific pitch notation, where middle C is C4 (some software calls the same note C3 or C5), and twelve-tone equal temperament.

Learn landmarks, not one sentence

Every Good Boy Deserves Football gets you reading this week and slows you down for years: reciting from the bottom line is serial, so finding the fourth space means counting four things. Quick readers know perhaps five notes on sight (the note the clef is named after, the middle one, the outside lines) and read everything else as an interval from the nearest one. The drill records which notes you are slow on, because a note answered correctly in three seconds is a note you counted.

Why four clefs instead of one

To keep notes on the stave instead of a pile of ledger lines. A cello sits badly in treble and a flute in bass; alto and tenor exist because the viola and the trombone sit between. The clef is chosen so the music lands in the middle: a printing decision as much as a musical one.

Why middle C looks different in every clef

The clefs put different pitches on the lines, and middle C is deliberately the note between the treble and bass staves. On a grand stave it is one ledger line under the treble or above the bass, the same note from either side. In the alto clef it is the middle line, which is where the C-clef’s centre points.

Name notes, not just finger positions

Position-only reading works on one instrument and collapses when you change clef, transpose, or try to tell anybody what you played. Naming is slower to learn and does not collapse. The drill names notes; the fretboard is on the scales page.

The drill repeats what you miss

Each note carries a weight that rises when you miss it or take long, and falls when you get it quickly; the next note is drawn against the weights. It is the crudest spaced repetition and still much better than random. The ladder colours show your accuracy per note: usually thinnest on the ledger lines and the notes just past the ones the mnemonic covers.

Questions

What people ask

Why are there four clefs instead of one?

To keep notes on the stave instead of on a pile of ledger lines. A cello's range sits badly in the treble clef and a flute's sits badly in the bass, and the alto and tenor clefs exist because the viola and the trombone sit between the two. The clef is chosen so the music lands in the middle, which is a printing decision as much as a musical one.

Why does middle C look different in every clef?

Because the clefs put different pitches on the lines, and middle C is deliberately the note that falls between the treble and bass staves. On a grand stave it is a single ledger line under the treble or above the bass — the same note, written from either side. In the alto clef it is the middle line, which is what the C-clef's centre points at.

Is it worth learning to name notes at all, or just where to put my fingers?

Both, but they are different skills and they fail differently. Position-only reading works on one instrument and collapses when you change clef, transpose, or try to talk to anybody about what you played. Naming is slower to learn and does not collapse. The drill here names notes; the fretboard is on the scales page.

Why does the drill repeat notes I got wrong?

Because an even shuffle spends most of its time on what you already know. Each note carries a weight that rises when you miss it or take a long time over it and falls when you get it quickly, and the next note is drawn against those weights. It is the crudest form of spaced repetition and it is still much better than random.

What do the colours on the ladder mean?

Your own accuracy on each note, once you have answered it a few times. It is a map of where your reading is thin — which is usually not where you would guess, and is usually the ledger lines and the notes just past the ones the mnemonic covers.

What this page assumes

Standard Western five-line staff notation, twelve-tone equal temperament, and scientific pitch notation where middle C is C4 — that last one is a convention, and some software calls the same note C3 or C5. Note values are named in British English (semibreve, minim, crotchet) with the American names given alongside. Nothing here covers percussion clefs, transposing instruments, or the several hundred years during which none of this was standard.

Twelve-tone equal temperament. Spelling and intervals follow the conventions of Western common-practice notation. Other tuning systems and other traditions name these relationships differently, and neither is wrong. See Sources.

That is not a claim that the tool never changed — a release that reworked many pages at once may well have altered this one too. The changelog has them.
