Hi,
In the previous article, we learned about ♭ and ♯. Today, we'll discover 2 more accidentals: double sharp (𝄪) and double flat (𝄫). Their use is mainly related to minor keys or diminished chords.
The double sharp (𝄪) raises a note one whole step, and looks like a cross.
Note that 𝄪F sounds like G. We'll see in the minor scales post why sometimes it is more convenient to write 𝄪F instead of G.
The double flat (𝄫) lowers a note by a whole step, and looks like two flats glued together.
𝄫B sounds like A. Like any accidental, a double flat cancels all previous accidentals and is cancelled by any accidental.
That's all for today! Have a good day, Sebastien
