A clef is a symbol placed at the beginning of a staff that determines which notes the lines and spaces represent. Without a clef, the staff is just five lines — the clef is what assigns pitch to each position.

The Treble Clef

The treble clef (also called the G clef) is the most widely used clef. Its spiral wraps around the second line of the staff, marking that line as G4 (the G above middle C). From there, you can figure out every other note by counting up or down.

Treble clef is used for:

  • Right hand piano
  • Guitar (sounds an octave lower than written)
  • Violin, flute, oboe, trumpet, and most high-register instruments
  • Vocal parts (soprano, mezzo-soprano, alto)

Lines (bottom to top): E – G – B – D – F (Every Good Boy Deserves Fudge)
Spaces: F – A – C – E (FACE)

The Bass Clef

The bass clef (also called the F clef) has two dots bracketing the fourth line of the staff, marking it as F3 (the F below middle C). It covers the lower range of pitches.

Bass clef is used for:

  • Left hand piano
  • Bass guitar and double bass
  • Cello, trombone, bassoon, tuba
  • Low vocal parts (baritone, bass)

Lines (bottom to top): G – B – D – F – A (Good Boys Deserve Fudge Always)
Spaces: A – C – E – G (All Cows Eat Grass)

The Alto and Tenor Clefs

The C clef moves around — wherever its center points is middle C (C4). In alto clef, the center is on the middle (third) line. In tenor clef, the center is on the fourth line.

  • Alto clef: used primarily for viola
  • Tenor clef: used for upper range of cello and trombone

These clefs minimize ledger lines for instruments whose range sits between treble and bass. You'll rarely encounter them as a songwriter unless you're writing orchestral arrangements.

Why Different Clefs Exist

Different instruments have different ranges. If everything used treble clef, bass instruments would need dozens of ledger lines below the staff to write their notes — nearly unreadable. Clefs position each instrument's typical range comfortably on the staff, with few ledger lines needed.

Guitar Notation

Guitar music is written in treble clef but sounds an octave lower than written. This is a convention to avoid the constant ledger lines that would be needed if guitar were written at true pitch. The small "8" sometimes seen hanging below the treble clef indicates this octave transposition — but it's often omitted in standard guitar notation.
