The Staff, Bar Lines & Measures
Five lines, four spaces, and a few vertical lines to keep time — the staff is the map every other symbol in music gets placed on.
The staff: a map of pitch
The staff (plural: staves) is 5 horizontal lines with 4 spaces between them. Every line and every space represents a specific pitch — the higher a note sits on the staff, the higher it sounds. Notes are drawn as ovals placed directly on a line, or nestled in a space, and a clef at the start tells you exactly which pitches those lines and spaces are.
Bar lines: a map of time
Running vertically through the staff, a bar line marks a checkpoint in time. The stretch of music between two bar lines is called a measure (or bar) — and every measure in a section holds the same number of beats, fixed by the time signature written at the start. That's what lets you count "1-2-3-4, 1-2-3-4" and always land back on beat 1 at the same spot.
Common questions

5 horizontal lines and the 4 spaces between them. Each line and space stands for a specific pitch.
What is a bar line?
A vertical line through the staff marking the end of one measure and the start of the next.

The music between two bar lines — it holds a fixed number of beats set by the time signature.
Do all measures have the same number of beats?
Yes, within one section — that consistency is exactly what makes counting along possible.
