So we went over the simple enharmonics in music theory 101. Now we will go over some advanced ones we talked about briefly in the comments on music theory 101.

Double sharps and double flats!

So since you can have one sharp, or one flat, then you could have 2, or 3, or how ever many. You usually don't see much past 2 though. So we will only be going over doubly accidentaled notes. 

So first the symbols for them!

Much like the normal sharp and flat they are attached to the upper right of the note.

A double flat is just two little b's & a double sharp is actually a small x. Like this:

Here are all the double flatted notes and what their enharmonic equivalent is:

• Abb = G
• Bbb = A
• Cbb = Bb(A#)
• Dbb = C(B#)
• Ebb = D
• Fbb = Eb(D#)
• Gbb = F(E#)

Here are all the double sharped notes and what their enharominic equivalent is:

• Ax = B(Cb)
• Bx = C#(Db)
• Cx = D
• Dx = E
• Ex = F#(Gb)
• Fx = G
• Gx = A

To double flat something you lower it two half steps, which is equal to one whole step.

To double sharp something you raise it two half steps, which is equal to one whole step.

Here is what all the notes look like in music with double flats and double sharps attached to them in treble and bass clef.

HOMEWORK: Write out two words using double flats & sharps. EXAMPLE: The word DAD in Enharmonics would be: Cx,Bbb,Ebb.
