C double flat

The musical note C-double-flat is the note two half steps below C. In music notation, C-double-flat is written by adding a double-flat sign (♭♭) to the note C. On a piano, C-double-flat is located on the right black key in each group of three black keys.

If we take a look a the key signature of the C Double Harmonic Major Scale we can find it has two flats and no sharps. Therefore, on sheet music you will find two accidentals on the score. The notes of this scale are: C, Db, E, F, G, Ab, and B.

So they're not like terribly. Difficult but we do have to get used to reading them. And get used to playing them.

Lower or a whole step lower which is the same as two half steps. So if you had a c double flat you would go down. The one half step. And the second half step.

For instance, the note B (a white key on the piano) can also be notated as C-flat.

The ♭ symbol universally indicates a flat note. It tells a player to sound a pitch half a tone lower than the written note.

C♭ major is a major scale based on C♭, consisting of the pitches C♭, D♭, E♭, F♭, G♭, A♭, and B♭. Its key signature has seven flats.

The Scales who use double-flats in the key signature (Db Minor, Gb Minor, Ab Minor) are just Theoretical Scales. Such key signatures could theoretically exist, but you won't find them used in practice. For example, instead of Gb minor, F# minor with three sharps is used.

The purpose of double sharps and flats in key signatures is to represent this scale in the way it is written, and avoid constant use of accidentals on a note - as per the example switching between G and G#.

And a double flat. Remember n harmonic notes. This b double flat will sound the same as a the e double flat will sound the same as d. And a double flat will sound the same as g.

Yes A double flat is enharmonically equivalent to G, but it is not G. Its an A lowered by 2 half steps. While the frequency will be the same as a G, it is not G. I stress this because its important to distinguish it from G, so that if you need to use it, you will know when to use it.

Since the rule is that each individual note of a scale must have its own letter name, having the Gb major scale move from Bb to B would violate that rule. So C-flat is the correct note name to use.
