The Staff and Clefs
A musical score uses a system of 5 lines called the staff or stave. Each line and each space between the lines represents a different note. The clef at the beginning of the staff is the "dictionary" that translates each position on the staff into an actual note.
The two most common clefs are the treble clef (used for high instruments and the keyboard's right hand) and the bass clef (used for low instruments and the keyboard's left hand). There is also the alto clef, used mainly for viola and trombone.
In the piano grand staff, the two staves are connected by a brace on the left, indicating that they should be read simultaneously — right hand on the upper staff (treble clef) and left hand on the lower staff (bass clef).
Notes in the Treble Clef
In the treble clef, the 5 lines of the staff (from bottom to top) correspond to the notes: E, G, B, D, and F. The spaces between the lines (from bottom to top) correspond to: F, A, C, and E.
Middle C (C4) is below the treble-clef staff, on a ledger line just below it. This is the reference point that connects the two piano staves.
Mnemonics for memorizing them: lines = "E, G, B, D, F" → remember "Every Good Boy Does Fine"; spaces = "F, A, C, E" → remember "FACE".
Notes in the Bass Clef
In the bass clef, the 5 lines of the staff (from bottom to top) correspond to: G, B, D, F, and A. The spaces (from bottom to top) are: A, C, E, and G.
Middle C (C4) is above the bass-clef staff, also on a ledger line, now above the top line. Once again, it is the meeting point between the two hands.
The bass clef is read in the same way as the treble clef — the only difference is the position of the notes on the staff. With practice, reading both clefs becomes automatic.
Note Values and Rests
Rhythmic figures are the symbols that indicate how long each note should last. The reference value is the quarter note, which is worth 1 beat in 4/4 time. All other note values are multiples or divisions of the quarter note.
Each rhythmic figure has a corresponding rest — a symbol that indicates silence for the same amount of time. Rests are just as much a part of the rhythm as notes.
- Whole note = 4 beats (rest: solid rectangle hanging from the 4th line)
- Half note = 2 beats (rest: hollow rectangle sitting on the 3rd line)
- Quarter note = 1 beat (rest: zigzag)
- Eighth note = 1/2 beat (rest: flag pointing to the left)
- Sixteenth note = 1/4 beat (rest: two flags)
- Augmentation dot: adds half the value to the note (e.g., dotted quarter note = 1.5 beats)
