Music: Bass Clef, Key Signatures and Guitar Tablature

C1.5 C1.4 C1.1About 40 minutes
Learning goals
  • I can name the lines and spaces of the bass clef staff and find middle C in both clefs.
  • I can read key signatures for C, G, D, F and B♭ major, and know that each one is shared by a minor key.
  • I can read simple guitar tablature.
  • I can play or sing pitches accurately, observing key signatures and accidentals (for example, B, A and G on the recorder).

Words to know

clef
A sign at the start of a staff that tells you the names of the lines and spaces.
bass clef
A clef for low sounds. Its two dots sit on either side of the F line (line 4), so it is also called the F clef.
key signature
The sharps or flats right after the clef. They tell you which notes are sharp or flat all through the piece.
accidental
A sharp, flat or natural sign written before one note. It lasts until the end of the bar.
relative minor
The minor key that shares a key signature with a major key. A minor is the relative minor of C major.
tablature (tab)
A way to write guitar music using lines for strings and numbers for frets.
fret
A metal strip on a guitar's neck. Pressing a string behind a fret changes its pitch.

Remember from Grade 4

In Grade 4 you read notes in treble clef (lines E G B D F, spaces F A C E), met middle C on a ledger line, learned sharps, flats and naturals, and read the key signatures for C major (none), G major (F♯) and F major (B♭).

This year you'll learn a second clef, two new key signatures, and a completely different kind of notation used by guitar players: tablature.

The bass clef

Low instruments and voices, like the tuba, cello, bassoon, bass guitar, the piano's left hand and low men's voices, read music in bass clef.

The bass clef starts with a dot on line 4 and has two dots, one on each side of that line. Line 4 is F, so it is also called the F clef.

  • Spaces, bottom to top: A, C, E, G. Saying: All Cows Eat Grass.

Bass clef: the lines are G, B, D, F, A and the spaces are A, C, E, G, from bottom to top. The clef's dots sit on either side of the F line.

Middle C in both clefs

Middle C is the same pitch in both clefs. In treble clef it sits on a ledger line just below the staff. In bass clef it sits on a ledger line just above the staff. On a piano, the treble and bass staffs are often joined (a grand staff), and middle C is the bridge between them.

treble: belowbass: above
Middle C is written on one ledger line below the treble staff, and on one ledger line above the bass staff. Both notes sound exactly the same.

Key signatures

A key signature sits right after the clef at the start of every line. If there is an F♯ in the key signature, every F in the piece is played as F♯, unless a natural sign cancels it.

Sharps and flats are always written in the same order:

  • Sharps: F♯, C♯, then more for other keys.
  • Flats: B♭, E♭, then more for other keys.
G majorD majorB♭ major
Three key signatures in treble clef: G major (F♯ on the top line), D major (F♯ and C♯), and B♭ major (B♭ on the middle line and E♭ in the top space).

1 flat: B♭F majorF G A B♭ C D E FD minor
2 flats: B♭, E♭B♭ majorB♭ C D E♭ F G A B♭G minor
Each key signature belongs to a major key and its relative minor. The relative minor starts on la, the 6th note of the major scale.

Tricks to name the key

  • Sharps: the last sharp is ti (note 7). The major key is the next note up, a half step higher. Last sharp C♯ → key of D major.
  • Flats: the second-last flat names the major key. B♭, E♭ → key of B♭ major. (With only one flat, B♭, remember: F major.)
  • Major or minor? Look at the music: does it seem to rest on do (major) or la (minor)? The last note is often a strong clue.

Guitar tablature

Guitarists often read tablature (tab) instead of the staff.

  • Tab has six lines, one for each string. The top line is the thinnest, highest string (high e). The bottom line is the thickest, lowest string (low E).
  • A number on a line tells you which fret to press on that string. 0 means play the string open (without pressing).
  • Read from left to right, like the staff.

Basic tab shows where to play, but not how long each note lasts, so guitarists often listen to the song too, or read tab and staff notation together.

Tab for the start of Mary Had a Little Lamb, all on the B string: frets 5, 3, 1, 3, 5, 5, 5 play E, D, C, D, E, E, E.

Playing what you read: the recorder

Many Grade 5 students play the recorder. Good technique helps you play pitches accurately:

  • Left hand on top, right hand on the bottom.
  • Your left thumb covers the hole on the back.
  • Cover holes with the soft pads of your fingers, not the tips, so no air leaks.
  • Sit or stand tall and blow gently, like warm air on a cold window. Start each note with your tongue: "too".

B: thumb + left finger 1. A: thumb + fingers 1 and 2. G: thumb + fingers 1, 2 and 3. Each finger you add makes the note a step lower.

Worked example

Example: Let's name a key signature and read a melody in it

A song in treble clef has two sharps in its key signature: F♯ and C♯. The melody is: D E F G A and it ends on D. What key is it in, and how do you play the F?

  1. Two sharps, F♯ and C♯: the last sharp is C♯. A half step above C♯ is D. So it's D major.
  2. Check: the melody ends on D, which is do in D major. That fits.
  3. The F: the key signature says every F is F♯, so the third note is played F♯, even though there is no sign right before it.
  4. The notes you play: D, E, F♯, G, A ... D.

The key is D major. Every F is played as F♯ (and every C as C♯) because of the key signature.

Worked example

Example: Let's read the bass clef

These whole notes are written in bass clef: line 2, space 3, space 1, line 3. Name them and say what word they spell.

  1. Bass clef lines from the bottom: G, B, D, F, A. So line 2 = B and line 3 = D.
  2. Bass clef spaces from the bottom: A, C, E, G. So space 3 = E and space 1 = A.
  3. Put them in order: line 2 = B, space 3 = E, space 1 = A, line 3 = D.

B, E, A, D: they spell BEAD. Try your own: in bass clef, "BAG" is line 2, space 1, line 1.

Just for fun

What do you get if you drop a piano down a mine shaft?

A-flat minor! (A♭ minor is a real key. The joke works because the piano is now flat and in a mine.) 🎹

Hands-on activity

Clef and key detectives

You need: paper, a pencil, a ruler, and a recorder, a keyboard app or a guitar if you have one.

  1. Draw two staffs with a ruler (5 lines each). Draw a treble clef on one and a bass clef on the other (the bass clef: a dot on line 4, a curve, and two dots on either side of line 4).
  2. Write the word CAGE in both clefs. (Bass clef: C = space 2, A = space 1, G = line 1, E = space 3.)
  3. Write the key signatures for G major, D major, F major and B♭ major. Check them with the picture in this lesson.
  4. If you have a keyboard app, play the D major scale. Listen: the F♯ and C♯ are black keys.
  5. If you have a recorder, play B, A, G slowly, then Hot Cross Buns: B A G, B A G, G G G G, A A A A, B A G.
  6. If you have a guitar (ask first), play the tab for Mary Had a Little Lamb on the B string.

For parents and teachers

Big idea: Students show their understanding of standard and other notation, including clefs, key signatures and guitar tablature (C1.5), use musicianship such as good recorder posture and interpreting accidentals and key signatures when playing (C1.4), and sing or play from notation (C1.1).

How to help at home:

  • Practise the sayings: bass clef lines Good Boys Do Fine Always; spaces All Cows Eat Grass.
  • A free keyboard app helps a lot: find middle C, play the D major scale and notice the black keys F♯ and C♯.
  • If your child plays recorder at school, short daily practice (5 minutes) with gentle breath is best.
  • If you play guitar, show your child how tab works. Many free tabs exist online, but check them against the recording.

Common difficulties:

  • Reading bass clef as if it were treble. Every note shifts! Line 1 is G (not E) in bass clef. Say the saying out loud while pointing.
  • Forgetting the key signature halfway through a song. Circle every F (in G or D major) in pencil before playing.
  • Squeaky recorder. Blow more gently and check that finger pads fully cover the holes, especially the thumb hole.
