In this video we're going to look at notes that go lower and higher than the notes we've already found on the treble clef. To write notes that are lower than those on the treble clef, we need to go a little bit in D, by drawing what's known as a ledger line under the treble clef like this. As you've probably guessed, this line must represent the note C, as its one natural node lower than D. If we want to go lower than that, we actually come to a whole new state. This is called the bass clef stave. The bass clef is for instruments that play in lower ranges such as the bass guitar, cello, and trombone. For example.

Piano music makes use of both high and low registers. It has a very wide range of notes from very low pitched on the left to very high pitched on the right. So it actually uses both the treble and bass clef together when an instrument uses both clips like this. They're joined together by a brace, and both the treble clef and the bass clef together are called the grand stave, or the great staff. The note on the ledger line between the treble and bass clips, is aptly called middle C. Just like the treble clef can also be called the G cliff. The bass cliffs other name is the F cliff.

Once again, that's a clue as to how the notes on the bass clef stave are arranged. The bass clef looks a little like an ear with two dots sitting above and below the fourth line of the stave. This indicates that the fourth line represents the load if the note on the space above F is G. The top line of the bass clef is the node A. The space above the bass clef is the node B. And then we arrive at a note on the ledger line, which is middle C. To go lower than a note if we just work backwards. The space below F is the note E aligned below that On the D, the space below that is see the line below that is B.

Then we have a on the first space G on the first line, and F on the space under the first line of the bass clef. Notice how the notes on the bass clef are shifted one line or space lower than they appear on the treble cliff. This is handy because if you know the notes on the treble clef, it's really easy to quickly find the notes on the bass clef to now although it's important to note about the bass clef, as guitar players, we don't actually use it as such. What we do instead is add two ledger lines below middle C, since that's as low as we need to go. These two ledger lines are the same as the top two lines of the base cliff. So they have exactly the same notes.

The note on the space below middle C is B, the line below that is a the space below that is G the line below that is f in the space below that is he we use ledger lines above the stage two for the high notes on the guitar. The line above the stave is node A, the space above that is B. The line above that is C. The space above that is D. The third line above the stage is the note E, and the space above that is the note F. Notice how the lower ledger lines up to the first line of the stave spell out face. Also, the spaces from below the third ledger line to the first space in the stave spill out our acronym, Every Good Boy does fine. You can see this above the stave two lines from the top line of the stave to the third ledger lines spill out face and the spaces from the last baseness Dave to the space above the third ledger line spells out every good boy does fine.

As we've seen the ledger lines represent the natural nodes. But of course we can turn any natural note on the ledger into a sharp or flat note to. For example, we can make these f notes F sharp notes instead by simply putting sharp signs in front of them. Or we can turn these B notes into B flat notes by adding flat signs. Lastly, let's observe lower and higher versions of the same note. For example, if we start on middle C, then add C on the third space of the treble clef, we have a lower and the higher version of the note C. The second C is said to be an octave above the first see, the word octave comes from the Latin word optimise meaning eight.

If we walk up all the nodes from middle C, we can see that the second C is the eighth note from middle C. Now we can go further than that to the second ledger line above the stave to find an even higher version of the node c to the third C is a further eight steps or octave above the C found on the third spaces. The treble clef. Now we find octaves occurring for all the notes on the stave. For example, here are the octaves of the note E. These are the octaves of the note F sharp. And here are the octaves of the node B flat. Now in the next lesson, we're going to practice writing the notes on the bass clef, making use of the ledger lines above and below the stave and checking out the octaves of a few notes.
