Note names

Nine places on a staff, seven letters, and one line per clef that tells you where you are. Learn the anchor and the rest fall out of it.

Five lines, four spaces

A staff is five lines with four spaces between them. A note is either sitting on a line — the line runs through the middle of it — or sitting in a space, tucked between two lines. That is nine positions, and naming a note starts with deciding which one you are looking at.

The nine positions on a staff, counted from the bottom up: line 1, space 1, line 2, space 2, and so on to line 5. Lines are numbered from the bottom, not the top.

Count lines from the bottom. Line 1 is the lowest, line 5 is the highest. Everyone forgets this at least once.

Seven letters, then start over

Music uses seven letter names: A B C D E F G. There is no H. After G you go back to A and keep climbing.

On the staff those letters run straight up the nine positions in order — line, space, line, space — one letter per step. So if you know any one position, you can count to any other.

Steps alternate

Line, space, line, space. Each move up is the next letter. Each move down is the previous one. Two notes on neighboring lines are two letters apart, because you skipped the space between them.

The treble clef names one line

A clef is not decoration. It is a marker that says this particular line is this particular note, and every other name on the staff is measured from it.

The treble clef's curl wraps around the second line from the bottom. That line is G — which is why it is also called the G clef. Find the curl, find G.

The treble clef spirals around the second line from the bottom. The note on that line is G — G4 in scientific pitch notation.

From there you count. One step up from G is A, the space above it. One step down is F, the space below. Nothing else needs memorizing to get an answer; the memory sentences below just make it faster.

All nine treble positions, E4 up to F5. Lines read E, G, B, D, F from the bottom. Spaces read F, A, C, E.
Treble lines, bottom to top
E G B D F — Every Good Band Does Fine
Treble spaces, bottom to top
F A C E — it spells a word, which is why everyone remembers this one first

The bass clef names one line too

Same idea, different line. The bass clef's two dots sit either side of the fourth line from the bottom — the second one down from the top. That line is F, which is why it is also called the F clef. The dots are pointing at it.

The bass clef's two dots straddle the second line from the top. The note on that line is F — F3 in scientific pitch notation.
All nine bass positions, G2 up to A3. Lines read G, B, D, F, A from the bottom. Spaces read A, C, E, G.
Bass lines, bottom to top
G B D F A — Good Burritos Don't Fall Apartor: Good Bands Do Fine Always
Bass spaces, bottom to top
A C E G — All Cows Eat Grass

These are classroom favourites, not rules. Any sentence works. If your band already uses a different one, keep it — the letters are what matter.

Same letters, new homes

Both staves use the same seven letters. What changes is where they live. The bottom line of a treble staff is E; the bottom line of a bass staff is G. Read a bass staff as though it were treble and every answer is wrong by two letters — consistently, confidently wrong, which is the hardest kind of mistake to catch.

So the first thing you read is never the note. It is the clef.

Anchor notes

Treble: the curl is on G. Bass: the dots straddle F. Middle C sits just outside both staves. Three landmarks, and everything else is counted from the nearest one.

Middle C is the seam

Middle C is one note, and it can be written on either staff. Below the treble staff it needs one short ledger line of its own. Above the bass staff it needs the same. Same pitch, same key on a keyboard, two spellings.

Middle C written below the treble staff, on one ledger line. This is C4.
The same middle C written above the bass staff, on one ledger line. Also C4 — one note, two ways to write it.

That shared note is what joins the two staves into a grand staff, and it is the reason a keyboard player reads both.

Where you will use this

Mnemonics are ladders

A memory sentence gets you to the answer, but reciting one costs you a second every time. Fluency is seeing the position and knowing the letter — no sentence in between. Use the ladder, then put it away.

The same topic, every way you need it

Hang it, read it, print it, drill it.

Every Backwerd topic identifies the faces that are ready — poster, lesson, printable sheet, app drill, board and teacher plans — and names an honest gap when one is not. The available faces share one set of conventions, so what hangs in the room never disagrees with what gets taught.
