StaffFive horizontal lines with four spaces between them. A higher note sits higher on the staff.
Treble clefIt curls around the second line from the bottom. This makes that line the note G.
Bass clefTwo dots sit above and below the second line from the top. This makes that line the note F.
BraceJoins the two staves of a piano part, one for each hand. It shows they are played together.
Key signatureSharps or flats written right after the clef. Each is on its own line or space. It comes before the time signature.
Time signatureThe top number tells how many beats are in each measure. The bottom number tells which kind of note gets one beat.
Bar lineBar lines divide the music into measures.
MeasureOne group of beats. A measure is also called a bar.
Ledger lineA short extra line for a note. The note is too high or too low to fit on the staff.
Double bar lineTwo vertical lines across the staff. A double bar marks the end of a section or of the whole piece.
Signs 12
SharpIt raises the note by a half step.
FlatIt lowers the note by a half step.
NaturalIt cancels a sharp or a flat that came before.
SlurThe notes under it are played or sung smoothly. There is no break between them.
StaccatoThe note is played short. That leaves a little space before the next one.
DotA dot after a note makes it half as long again.
TieThe two notes sound as one long note. The second is not played again.
FermataHold the note longer than its written length.
Piano (p)Play softly. Piano means soft.
CrescendoGradually get louder.
Forte (f)Play loudly. Forte means loud.
Repeat signPlay the section again. With no matching sign earlier in the music, go back to the beginning.

How it works
Four bars of piano music written for this page. The first two show the parts of a staff; the last two carry the signs a beginner meets. Each one is named here; press Quiz me, or print the sheet blank for a first theory lesson.
Read the full guide
Start with the parts of a staff
Numbers 1 to 10 are on bars 1 and 2: the staff, the two clefs and the brace, the key signature and the time signature, a bar line, a measure, a ledger line and the double bar line.
Then the signs
Numbers 11 to 22 are on bars 3 and 4: sharp, flat and natural, the slur and the staccato dot, the dot and the tie, the fermata, piano, crescendo and forte, and the repeat sign.
Print it for a class
Print blank gives both lines of music with numbered rings and a line for each name, for an elementary music, general music or band class. Print labeled adds the key.
A tie joins two notes of the same pitch. A slur covers notes of different pitches.
Read a time signature from the top: the beats in a measure, then the kind of note that gets one beat.
Questions and answers
What are the parts of a music staff?
The staff is five lines and four spaces. A clef starts it, then the key signature and the time signature. Bar lines divide it into measures, ledger lines carry notes above or below it, and a double bar line ends a section.
What does a time signature mean?
The top number tells how many beats are in each measure. The bottom number tells which kind of note gets one beat. In four-four time there are four beats in a measure and a quarter note gets one beat.
What is the difference between a tie and a slur?
Both are curved lines. A tie joins two notes of the same pitch, and they sound as one long note. A slur joins notes of different pitches, which are played smoothly with no break between them.
What do p and f mean in music?
They are dynamics, the signs for how loud to play. The letter p stands for piano, which means soft, and f for forte, which means loud. A crescendo between them means get louder little by little.
Can I use this as basic music theory worksheets?
Yes. Print blank gives the four bars with a numbered ring on each sign and a line to write its name on. Print labeled gives the same sheet with the key.
