How to read music

To read music you need two things: which note (its line or space on the staff, read with the clef) and how long (the shape of the note, counted against the time signature). Everything else, from key signatures to dynamics, adds detail to those two.

1. The staff

Music is written on a staff (also spelled stave): five horizontal lines with four spaces between them. Each line and each space stands for one letter name. The higher a note sits, the higher it sounds. Moving from a line to the space right above it moves up one letter, and the letters run A to G and then start over.

Vertical lines called bar lines split the staff into bars (also called measures). Each bar holds the same number of beats. A double bar line with a thick second line means the end of the piece.

2. Clefs tell you which notes the lines are

The five lines don't mean anything until a clef sits at the start of them. The treble clef is for higher sounds: its lines are E, G, B, D, F and its spaces spell FACE. The bass clef is for lower sounds: lines G, B, D, F, A and spaces A, C, E, G. Piano music uses both at once, joined at middle C.

Notes above or below the staff get short ledger lines. In the example above, the first C sits on a ledger line below the treble staff: that is middle C.

3. Note values: how long each note lasts

The shape of a note tells you its length in beats. A hollow oval with no stem is a whole note; add a stem and it's a half note; fill it in for a quarter note; add a flag for an eighth, two flags for a sixteenth. Each value is half as long as the one above it. Eighth and sixteenth notes next to each other are often joined by a beam instead of flags, as in bar two of the example.

Every note has a matching rest: a symbol for silence of the same length. Press a button to hear one bar of each value against a click on every beat.

A dot after a note adds half its value again: a dotted half note lasts 3 beats, a dotted quarter lasts 1½. A curved tie joining two notes of the same pitch means hold for both values without playing the second one.

4. Time signatures: how beats are grouped

The two stacked numbers after the clef are the time signature. The top number says how many beats are in each bar. The bottom number says which note gets one beat: 4 means a quarter note, 8 means an eighth note. Listen for the higher note on beat 1 of each bar.

To keep the beat steady while you read, practice with the online metronome, which has all four of these time signatures.

5. Key signatures: the sharps or flats for the whole piece

Right after the clef you may see a group of sharps (♯) or flats (♭). That is the key signature. It tells you to play those notes sharp or flat every time they appear, in every octave, unless the music says otherwise. It also tells you the key of the piece.

No sharps or flats at all usually means C major or its relative, A minor. The full list, with every key drawn, is on key signatures, and the circle of fifths shows how they connect.

6. Accidentals: one-off sharps, flats and naturals

A sharp, flat or natural written right in front of a single note is an accidental. It changes that note, and any repeats of the same note, until the next bar line. A sharp raises by a half step (one key on the piano), a flat lowers by a half step, and a natural sign (♮) cancels a sharp or flat.

The distance a note moves is an interval. A half step is the smallest one; learning to see and hear intervals is the step that turns note-by-note reading into reading shapes.

7. Dynamics: how loud

Letters under the staff tell you how loud to play. They come from Italian.

A long opening wedge (or cresc.) means get gradually louder; a closing wedge (or dim., decresc.) means get gradually softer.

8. Putting it together: reading the example

1. Clef: treble, so the bottom line is E4.
2. Time signature: 4/4, four quarter-note beats per bar. Count "1, 2, 3, 4" before you start.
3. Bar 1: C (ledger line, 1 beat), E (bottom line, 1 beat), G (second line, a half note, 2 beats). That's 1 + 1 + 2 = 4 beats.
4. Bar 2: four beamed eighth notes F, E, D, E, counted "1 & 2 &", then C for one beat on 3 and a quarter rest on 4. Again 4 beats.
5. Check: every bar adds up to the top number of the time signature. If a bar doesn't, you misread a note value.

Press play on the example again and count out loud with the clicks. Then try reading it without the sound. When that feels easy, the music theory guide explains why these notes fit together, and the C major scale page lets you hear all seven notes used here.
