Piano notes: how the keys match the staff
Each piano key matches one spot on the staff. Middle C is the key near the center and sits on a ledger line between the treble and bass staves. Keys to the right are higher and are mostly read in the treble clef, and keys to the left are lower and read in the bass clef.
Learning piano notes means connecting three things: the key you press, the note you see on the staff, and the sound you hear. This page links the first two. It shows which keys belong to the treble clef and which to the bass clef, where the black keys go, and how to find your way around with a few landmark notes.
Where do the keys go on the staff?
Start from middle C, the key near the center of the piano. It is the first ledger line below the treble staff and the first ledger line above the bass staff. Moving up, the white keys follow the letters C D E F G A B, and the notes climb the treble staff line, space, line, space. Moving down from middle C, the notes go B, A, G, F, E, D, C down the bass staff. Each white key is exactly one step of the staff.
Which hand plays which staff?
In most piano music the right hand reads the treble staff and the left hand reads the bass staff, but the hands often cross over. A melody in the left hand can appear in the treble staff, and a bass line can go into the right. The staves show pitch, not hands. Some editions add small numbers above the notes to show which finger to use, with 1 for the thumb and 5 for the little finger.
How are the black keys written?
Black keys are written with a sharp or flat sign before the note. A sharp raises the note to the black key on the right, and a flat lowers it to the black key on the left. For example the black key between F and G is written as F♯ or as G♭, depending on the key of the music. The staff itself has no special spot for black keys, so the sign carries that information.
How do the white keys line up with the five lines?
The five lines of the treble staff go E G B D F, and these are all white keys. On the keys, they are every other white key starting with the first E above middle C. The spaces, F A C E, are the white keys in between. If you press the keys for the lines in turn, you play every other white key. The bass staff works the same way, with lines G B D F A.
What are the octaves on the piano?
An octave is the span from one note to the next with the same letter, such as C4 to C5. On the piano that is eight white keys counting both ends, or 12 half steps if you count every key, black ones included. The octave number changes at each C, so the keys from C4 to B4 are all in octave 4. A piano has seven full octaves plus a few extra keys. The standard tuning reference is A4, the A above middle C, at 440 Hz.
| Key | Note name | Staff position |
|---|---|---|
| Middle C | C4 | Ledger line below treble, above bass |
| The G above middle C | G4 | Second line of treble |
| The F below middle C | F3 | Fourth line of bass |
| Top of treble staff | F5 | Fifth line of treble |
| Bottom of bass staff | G2 | First line of bass |
How do I find notes quickly?
Use landmarks. Find middle C by the pair of black keys, then find the treble G and bass F by counting. Name the notes of a short tune, then play them, then name them again without looking. Little by little you stop counting and start to recognize notes by sight, like words. The note trainer helps with this, and piano keys lists every key.
- Find middle C on the keys.
- Find the same note on the staff, on its ledger line.
- Move up or down one white key and one step on the staff together.
- Say the names out loud as you play.
Practice tip: Practice reading and playing only five notes first (C D E F G), then add one new note at a time. A small set that you know well is better than many notes that you half know.
When you are comfortable with these notes, read a simple piece with both hands. See how to read sheet music for what else to look for on the page, and the grand staff page for how the two staves fit together.
