Double Sharps and Flats

Wassup Guys!


I wanted write a quick post today talking about the use of double sharp and flat accidentals in major scales! I'm posting a new video this week on my YouTube, thekeysignature talking about how they also work in Major Scales!


Let's define what each of these symbols are.


When we see a single sharp next to a letter name, we know to raise the note by a half step or semitone. 


A# is one half step higher from A

So when we see a double sharp next to a note, we know to raise the note by two half steps, which is a whole step, or whole tone. 


For instance. If I see the note Ax Double Sharp I know to move two half steps away from the note A going up. This is what that distance looks like on a keyboard. After traveling a whole step away from A, we land on B. So that means when I see an Abb on a piece of sheet music, I know that the note I will be singing, hearing or playing on the piano is the note B. 

When we see a single flat next to a letter name, we know to lower the note by a half step. 


Ab is one half step lower from A

So a double flat will be double that distance. Two half steps, which will make a whole step or tone. 


If I see the note Abb Double Flat, I know to move two half steps away from the note A going down. This is what that distance looks like on a keyboard. After traveling a whole step away from A lowering the note, we land on G. That also means that when I see an Abb Double Flat on a sheet of music, I will be singing, hearing or playing the note G on the piano. 

Double Sharp and Flat accidentals refer to the distance of one whole step or tone away from a letter name. Whether we are raising or lowering a note by that whole tone distance will depend on whether it's a doubled sharp or flat. 

I hope that this post was helpful and made sense to all you guys out there learning! I’ve linked my video to Building Major Scales down below as well! Check out my website, my Instagram accounts and my Etsy shop where I started selling some of my music art as PDF Digital Downloads to use as study guides, reference sheet or framed art! Thank you guys so much for watching! Stay tuned for my next post!
