The Staff and Clefs

Five lines, two clefs, and every note has an address.

Think of the staff as a ladder for sound. The higher a note sits on the ladder, the higher it sounds. The clef at the start tells you which rung is which, so you can give every note its letter name.

1The staff

A staff is five lines with four spaces between them. Notes sit either on a line (the line runs through the middle of the note) or in a space. Musicians always count lines and spaces from the bottom up.

The staff. Line 1 is the bottom line; space 1 is just above it.

2Clefs: the key to the staff

On its own, a staff doesn’t say which notes it holds. A clef at the start of the staff fixes one line to one note, and every other note follows from there.

Treble clef (G clef): its curl wraps around the second line from the bottom, so that line is G (the G just above middle C). It’s used for higher sounds: flute, violin, trumpet, most singing, and the right hand on piano.
Bass clef (F clef): its two dots sit on either side of the second line from the top, so that line is F (the F just below middle C). It’s used for lower sounds: cello, tuba, bassoon, and the left hand on piano.

The treble clef marks the G line. The bass clef marks the F line.

3Treble clef note names

Music uses only seven letters, A to G. Going up the staff, each line or space is the next letter. On the treble staff, the lines and spaces spell out patterns you can memorize:

Treble staff: lines E G B D F, spaces F A C E.

E G B D FLines: Every Good Boy Does Fine (or make up your own, like Elephants Got Big Dirty Feet)

F A C ESpaces: they spell FACE, like a face in the space

4Bass clef note names

The bass staff uses the same seven letters, but everything shifts. It’s a common mistake to read bass notes as if they were treble, so learn these as a fresh set:

Bass staff: lines G B D F A, spaces A C E G.

G B D F ALines: Good Boys Do Fine Always

A C E GSpaces: All Cows Eat Grass

5Ledger lines and middle C

What about notes higher or lower than the staff? Musicians add short extra lines called ledger lines just for those notes.

Put a treble staff above a bass staff, join them with a brace, and you get the grand staff that pianists read. Right between the two staffs sits middle C on its own ledger line. It’s the same note whether it’s written just below the treble staff or just above the bass staff, and it’s near the middle of a piano keyboard.

Quick quiz

Four questions. Choose an answer for each, then check them all at once.

1. How many lines does a modern music staff have? Four, like Guido’s staffs Six Five Seven, one for each letter A to G

2. Why is the treble clef also called the G clef? It curls around the line it names as G It was invented by a musician whose name began with G It is only used for songs in the key of G major G is the lowest note it can show

3. On the bass staff, which note sits on the bottom line? E F A G

4. What are ledger lines for? Notes too high or too low to fit on the staff Marking the end of a song Showing which notes to play loudly, softly, or in between Separating one measure from the next

Talk About It

Discuss with a partner, your class, or your family. There are no wrong answers here.

Why do you think music uses only seven letters (A to G) instead of a different letter for every note?
Make up your own memory sentence for E G B D F or A C E G. What makes a memory sentence easy to remember?
The piano needs both treble and bass clef. Which instruments in a band or orchestra do you think need only one? Why?
