Treble Clef and Bass Clef Guide: What Are Clefs in Music?

Clefs are a visual symbol used in music notation. In Western sheet music, notes are printed on musical staves containing lines and spaces. Clefs, such as the treble clef and bass clef, tell musicians what notes those lines and spaces represent.

Western music theory uses many different clefs including soprano clef, alto clef, and tenor clef. However, the treble and bass clefs appear more than any others—most notably in the grand staff that makes up piano notation.

The treble clef is the most used clef in Western music notation. It primarily notates musical notes above middle C.

The treble clef is shaped like an ornamental letter G, and its inner curve surrounds the note G4 that falls above middle C. For this reason, the treble clef is nicknamed the G clef. Many instruments—including the trumpet, violin, guitar, and oboe—read music off the treble clef. It is also used on the piano grand staff to notate music played by the right hand.

The bass clef is shaped like an ornamental letter F, accompanied by two dots that bracket the music note F3, which is the first F below middle C. For this reason, it is nicknamed the F clef.

The bass clef is the most common clef for double bass, bass guitar, trombone, and timpani. Cello players can read bass clef, but most of their music is notated for tenor clef. In piano notation, the bass clef typically contains music to be played by the left hand.

Reading music at a professional level can take years of practice, but the basics of the treble clef and bass clef notations are quite simple. Each line and space in the musical staff corresponds with a specific note, and the clef informs the reader of the specific note names.

1. 1. The space above the top line is the note G5.
2. 2. The top line is F5.
3. 3. The top space (below the top line) is E5.
4. 4. The second line from the top is D5.
5. 5. The second space from the top is C5 (an octave higher than middle C).
6. 6. The third line from the top is B4.
7. 7. The third space from the top is A4.
8. 8. The fourth line from the top is G4.
9. 9. The fourth space from the top is F4.
10. 10. The bottom line is E4.
11. 11. The space below the bottom line is D4.
12. 12. The ledger line below the staff is C4 (middle C).

You can add additional notes above and below the staff by drawing additional ledger lines. You can signify flats and sharps by using their respective notation.

Reading music in bass clef is quite similar to the process in treble clef, although the spaces and lines correspond to different note names.

1. 1. One ledger line above the staff is C4 (middle C).
2. 2. The space above the top line is the note B3.
3. 3. The top line is A3.
4. 4. The top space (below the top line) is G3.
5. 5. The second line from the top is F3.
6. 6. The second space from the top is E3.
7. 7. The third line from the top is D3.
8. 8. The third space from the top is C3 (an octave lower than middle C).
9. 9. The fourth line from the top is B2.
10. 10. The fourth space from the top is A2.
11. 11. The bottom line is G2.
12. 12. The space below the bottom line is F2.
13. 13. The ledger line below the staff is E2.

Music notation uses other common clefs, including soprano clef, alto clef, and tenor clef. The symbol for all of these clefs resembles a double letter C, and it is accordingly known as a C clef. The C clef always points at the note C4 (middle C). What distinguishes one C clef from another is where middle C is located on the staff.

The soprano clef is used to notate soprano vocals.

The alto clef is used to notate mandola, viola, viola d'amore, viola da gamba, and alto trombone.

The tenor clef is used to notate cello, euphonium, and high bassoon.
