Fundamentals: Staff, Clefs & Accidentals Practice
The basic building blocks of written music — the staff, clef names, and what sharps, flats, and naturals do to a note.
Read the staff and change a note with accidentals
A staff has five lines and four spaces. A clef gives those positions their note names: the treble (G) clef curls around the second-line G, while the two dots of the bass (F) clef surround the fourth-line F. Read the clef before naming any note.
A sharp raises a written note by one semitone, a flat lowers it by one semitone, and a natural cancels a sharp or flat. These symbols change pitch, not loudness or note length.
How to work it out
- Find the clef and count from a known staff line or space to get the letter name.
- Check the key signature and any accidental beside the note before stating its full name.
Worked example
A B sits on the middle line of a treble-clef staff. What does a flat before it change?
The letter remains B, but the flat makes it B flat, one semitone lower than B natural. The length of the note does not change.
Watch for this mistake
Do not treat a natural as a new note name: it restores the unaltered pitch of the same letter.
Learning objectives
- Know how many lines and spaces make up a standard music staff.
- Know the other names for the treble and bass clefs.
- Know what a sharp, flat, and natural sign each do to a note.

Answer Key
- 5 — A standard music staff has 5 lines (and 4 spaces between them).
- G clef — The treble clef is also called the G clef, because it curls around the line where G sits.
- F clef — The bass clef is the F clef because its two dots frame the staff's fourth-line F.
- Raises it by a semitone — A sharp raises a note by a semitone (half step).
- Cancels a previous sharp or flat — A natural sign cancels a sharp or flat that came before it, returning the note to its normal pitch.
- It falls by one semitone — The flat changes B natural to B flat, one semitone lower. It changes pitch, not volume.
- Returns the second B to B natural — The natural cancels the earlier flat, returning the second note to B natural.
- F natural — The natural cancels the earlier sharp, so the second note is F natural.
1. How many lines does a standard music staff have?
💡 Count the long horizontal lines of the staff, not the spaces between them.
2. The treble clef is also known by which other name?
💡 Look at the line that the treble-clef spiral curls around; it names the clef.
3. The bass clef is also known by which other name?
💡 Find the line framed by the two dots of the bass clef; that line gives the clef its other name.
4. What does a sharp sign (♯) do to a note?
💡 Imagine the next adjacent piano key to the right of the unaltered note.
5. What does a natural sign (♮) do?
💡 Think about a note altered earlier in the bar. Does that alteration still apply after this sign?
6. This B has a flat sign. Compared with B natural, what happens to its pitch?
💡 Compare the written note with B natural on a keyboard. Which neighbouring key does the flat sign indicate?
7. The first B is flat. What does the natural sign before the second B do?
💡 Read the two signs from left to right. The sign before the second note cancels the earlier change.
8. The first F is sharp. What pitch does the second F have after the natural sign?
💡 The first sign raises F. Look at the second sign: it removes that earlier alteration.
