How to Read Sheet Music (The Basics)

Sheet music looks dense at first, but it's built from a small number of repeating rules. Here's the core of it.

The staff and the clef

Notes are written on a staff: five horizontal lines, with four spaces between them. A clef at the start tells you which pitch each line and space represents. The treble clef (shown below), used for higher- pitched instruments and the right hand of the piano, curls around the second line from the bottom, fixing that line as the note G.

The five lines, bottom to top: E–G–B–D–F ("Every Good Boy Does Fine").

The four spaces, bottom to top: F–A–C–E — conveniently, it spells "FACE."

Bass clef (used for lower-pitched instruments and the piano's left hand) labels the same five lines and four spaces differently, curling around the line that marks F instead of G — the shape of the staff is identical, only the reference point changes.

Note duration

How long a note lasts is shown by its shape, not its position. A hollow notehead with no stem (a whole note) lasts twice as long as a hollow notehead with a stem (a half note), which lasts twice as long as a filled-in notehead with a stem (a quarter note), which lasts twice as long as a quarter note with a flag attached (an eighth note). Each step down halves the previous duration — a consistent, predictable system once you've seen it once.

Measures and time signatures

Vertical lines called bar lines divide music into measures (or "bars"), each holding a fixed number of beats. A time signature at the start (like 4/4 or 3/4) tells you how many beats fill each measure, and which note duration counts as one beat — 4/4 means four quarter-note beats per measure, the most common time signature by far.

Where this connects

Once the staff and rhythm feel familiar, our glossary of musical terms covers the Italian words (forte, allegro, and the rest) that tell a performer how to play what's written, and our dynamics and tempo markings guide goes deeper on exactly those two categories.
