Bass clef notes

The bass clef's lines are G, B, D, F, A and its spaces A, C, E, G, from the bottom up. Its two dots sit either side of the fourth line, F, the F just below middle C, which makes it the quickest landmark for reading the left hand.

The bass clef's five lines are G, B, D, F, A from the bottom up, and its four spaces are A, C, E, G. The clef's two dots sit either side of the fourth line, which is F: the F just below middle C. Learn that F on sight and you can read every other bass note as a step or a skip from it.

The bass clef is an F

The bass clef sign grew out of an old letter F. Its curl starts on the fourth line, and its two dots sit just above and just below that line, pointing straight at it. That line is F, the F just below middle C (F3). That is why the bass clef is also called the F clef, just as the treble clef, which curls round G, is the G clef.

This is the most useful fact about the bass clef. You never have to count up from the bottom line: find the dots, and you have found F.

Every note on the bass staff

Middle C is C4. The C an octave below it, in the bass staff's second space, is C3. The numbers change at every C.

Note	Where it sits	On the keyboard	Read it from a landmark
G2	The bottom line	The second G below middle C	A skip below B, a fourth below bass C
A2	The bottom space	The second A below middle C	A skip below bass C
B2	The second line	The second B below middle C	A step below bass C
C3	The second space	The C an octave below middle C	Bass C, a landmark of its own
D3	The middle line	The first D below middle C	A step above bass C, a skip below bass F
E3	The third space	The first E below middle C	A step below bass F
F3	The fourth line, between the dots	The first F below middle C	Bass F, the landmark
G3	The top space	The first G below middle C	A step above bass F
A3	The top line	The first A below middle C	A skip above bass F, a skip below middle C

Just outside the staff:

Note	Where it sits	On the keyboard
B3	The space just above the staff	The B just below middle C
C4	One ledger line above the staff	Middle C
F2	The space just below the staff	The second F below middle C
E2	One ledger line below the staff	The second E below middle C

On the keyboard

Most bass-clef notes are played by the left hand, left of middle C. Find them from the black keys:

Every F is just left of a group of three black keys. Bass F is the first F to the left of middle C.
Every C is just left of a group of two black keys. Bass C is the C an octave (eight white keys) below middle C.
Every G is between the first and second of the three black keys, and every A between the second and third.

Two hand positions cover most beginner bass parts:

Middle C position. Left thumb on middle C, fingers stepping down: B, A, G, and the little finger on bass F. This hand reads straight down from middle C to the F landmark.
C position. Left little finger on bass C (C3), thumb on G3. One finger for each of C, D, E, F, G. Remember that the left thumb is finger 1 too, and the little finger is 5.

Memory aids

The rhymes help at the start:

Lines, bottom to top: G B D F A, "Good Boys Do Fine Always" (or "Good Bikes Don't Fall Apart").
Spaces, bottom to top: A C E G, "All Cows Eat Grass" (or "All Cars Eat Gas").

Rhymes are slow, though: to read the fourth line you say three words first, and they stop at the edge of the staff. Aim to replace them with landmarks:

F, between the dots.
Middle C, one ledger line above the staff.
Bass C, the second space, where the left hand's C position starts.
Low G, the bottom line: the lowest line of the grand staff.

Read the rest as steps and skips from whichever landmark is closest. Why landmarks beat rhymes.

Common mistakes

Reading the bass staff as if it were treble. This is the most common mistake there is. A note on the bass staff's top line is A, but a note in the same place on a treble staff is F: two letters apart. Look at the clef before you read the first note of every line.
Translating from the treble. Some learners read a bass note as a treble note and then add two letters. It works, slowly, and it breaks under pressure. Learn the bass staff on its own terms, from F.
Counting from the bottom line every time. Start from the nearest landmark instead: F for the top half of the staff, bass C or low G for the bottom half.
Mixing up middle C's two homes. Middle C is one ledger line above the bass staff or one below the treble. It is the same key either way; the clef says which hand usually plays it.
Using the wrong finger numbers. In the left hand the thumb is still 1 and the little finger 5, so finger numbers run the opposite way along the keys.

How to practise

Find F by sight. Look at a page of bass clef and touch every note on the F line, between the dots. Then play them, the F just below middle C.
Step out from F. G is a step up, the top space. E is a step down, the third space. Play F G F E F, reading, not counting.
Add the skips. A is a skip above F (the top line); D is a skip below (the middle line). Then bass C in the second space.
Reach the bottom. B, A and G are the second line, bottom space and bottom line. Low G is two octaves below the treble clef's G line.
Mix both clefs. Once the bass feels safe, read cards that switch between treble and bass, so your eye learns to check the clef.
Play simple left-hand tunes. Hot Cross Buns moved down to A G F, read from bass F, is a good first one.

How Octotune helps

Octotune's adult path brings in the bass clef in three steps. Unit 3 reads from middle C down to bass F, with the left thumb on middle C. Unit 5 adds bass C, D and E, the left hand's C position, and both hands together. Unit 8 takes the left hand down to the bottom line, low G.

In the Mix exercises, treble and bass notes come side by side, so you have to look at the clef to answer. Every answer is played on your keyboard. Open Octotune to start.

Next: Treble clef notes, and the grand staff, where the two meet at middle C.

Questions

What are the notes of the bass clef lines?

From the bottom line to the top: G, B, D, F, A. A common rhyme is Good Boys Do Fine Always.

What are the notes of the bass clef spaces?

From the bottom space to the top: A, C, E, G. A common rhyme is All Cows Eat Grass.

What do the two dots on the bass clef mean?

They sit either side of the fourth line from the bottom, and that line is F: the F just below middle C (F3). That is why the bass clef is also called the F clef.

Where is middle C in the bass clef?

On one short ledger line just above the bass staff. It is the same key as middle C written one ledger line below the treble staff.

Why do I keep reading bass notes wrong?

Usually because you are reading them as if they were in the treble clef. The same line or space is a different note in each clef: the bass staff's top line is A, but the treble staff's top line is F. Check the clef first.
