The music staff and the grand staff: lines, spaces and ledger lines

The staff is the set of five horizontal lines on which music is written. Each line and each space is one note, and the higher a note sits, the higher it sounds. The clef at the start tells you which note is which, and piano music joins two staves into one grand staff, with middle C in between. Let's look at each of these ideas in turn, with sound, and then you'll practice reading.

Five lines, four spaces

Lines and spaces are counted from the bottom up, so line 1 is the lowest and line 5 the highest. Moving from a line to the next space, or from a space to the next line, is one step in the musical alphabet: A, B, C, D, E, F, G, then A again. Without a clef, the staff only shows you high and low. It's the clef that gives the notes their names.

Here are the lines of the treble staff, from bottom to top: E, G, B, D and F.

And the spaces of the treble staff spell F, A, C, E.

The grand staff

Now let's join two staves. The grand staff, also called the great staff, is a treble staff and a bass staff joined on the left by a brace. The right hand usually reads the top staff, and the left hand the bottom one. Middle C sits exactly between them, on a short line of its own: one ledger line below the treble staff, or one ledger line above the bass staff. Either way, it's the same key on the piano.

Listen to middle C on both staves, then to the lines of each staff moving outward: E, G, B, D, F on top, and A, F, D, B, G below.

Ledger lines

And when a note is too high or too low for the staff? Short ledger lines extend it, one line at a time, keeping the same pattern of line, space, line. Beyond three or four ledger lines, music usually switches clef, or uses an octave sign, written 8va, to stay readable.

These are the notes above the treble staff, on ledger lines and in the spaces between them.

And these are the notes below the bass staff.

Frequently asked questions

How many lines are on a music staff?

A staff has five lines and four spaces. Notes are written on the lines, in the spaces, and on ledger lines above or below.

What is the grand staff?

It's a treble staff and a bass staff joined by a brace, used for piano, harp and organ. Middle C lies between the two staves.

Where is middle C on the grand staff?

It sits on one ledger line below the treble staff, or on one ledger line above the bass staff. Both are the same note.

What are ledger lines?

They're short extra lines above or below the staff, for notes outside its range. They follow the same pattern of lines and spaces as the staff itself.
