Let's talk about the Bass Clef.
Bass clef
Think of the piano keyboard again, and split it down the middle. This clef tells you to play or sing the notes on the left side of the piano, which are all the lower notes on a staff. This is the BASS CLEF.
The word “Bass” means lower, so when we read notes on a staff that has a Bass clef, we will be reading notes that are played by instruments like trombones and tubas, or sung by people that have a lower voice. The bass clef is found at the beginning of a staff and looks like this:
The Notes
When you put a bass clef at the beginning of a staff, you can read all the lower lines and spaces with their appropriate notes. When you read the lines and spaces on a staff, the bottom line or space is the first one, and you count up from there. The lines of a bass clef staff are, from the bottom (first) line are:
G, B, D, F, A
(Another cool little saying to help remember this is Good Boys Do Fine Always!)
The spaces of a bass clef are, from the bottom (first) space are:
A, C , E, G
(Remember this by the phrase All Cows Eat Grass!)
Where do they go?
Here are some pictures of some of the notes to help you out:
Now remember, notes can appear on ledger lines and the spaces in between them above and below the staff. Just like in treble clef. You count the lines and space the same way, just with the new set of notes you have learned. Here is example of a “E” below the staff on a ledger line:

Now, don’t get the treble and bass clefs confused, or the music you will be singing or playing will sound really weird!
F-Clef (it's the same thing)
EXTRA: bass clef also has another name! It’s called the F Clef. Notice how the clef starts on the F line and has the 2 dots that are on either side of the F line. That’s why it’s called the F Clef.
