an easy way to do scales like that is to first find the e flat major scale, then to flat everything once (or twice in this case.)
it's a bit messy but the notes would be:
Ebb Fb Gb Abb Bbb Cb Db Ebb
I definitely suggest transposing to D major, good sir..
C flat Major
G-flat major scale has the most with 6 flats: b-flat, e-flat, a-flat, d-flat, g-flat, and c-flat.Of course, one could argue that other scales have more flats (such as C-flat major, F-flat major, B-double-flat major, etc), but these scales are typically notated as their enharmonic equivalent (e.g. A major instead of B-double-flat major).
The subdominant in a scale is the 4th, which in the key of B-flat major is E-flat.
The E flat scale
The key of C Major consists of these notes: C, D, E, F, G, A and B.The key of C Harmonic Minor consists of these notes: C, D, E-flat, F, G, A-flat and B.The key of C Melodic Minor consists of these notes: C, B-flat, A-flat, G, F, E-flat and D. However, when played ascending as a scale, the sixth (A-flat) and seventh (B-flat) notes/degrees would be sharped, leaving us with B and A. On the way back down they are restored to A-flat and B-flat.
C flat Major
Such a key only exists in theory and not in practice. In C-double-flat major, every single note (C D E F G A B C) would have a double-flat on it, and it would sound the same as B-flat major.
The C major scale and its relative minor, the A minor scale. C Major.
The notes in an f major scale are just all notes from one f two the next with a b flat instead of a b natural.
B flat
The scale of 'C' - it uses neither sharp or flat notes.
Gb, Ab, B, Cb, Db and Eb.
b flat, c, d, e flat, f, g, a, b flat
The notes in the F major scale are: F, G, A, B flat, C, D, E, F
There are no flats or sharps. Its relative major scale is C major, which has all of the same notes.
The Keys of B-flat, E-Flat, A-Flat, D-Flat, G-Flat, C-Flat, and F-Flat major all contain the note E-flat. F-flat major is a key which only exists in theory and not in practice, since there is a double flat in that scale (subdominant). The major scale with the most flats is C-flat major - with all seven flats.
G-flat major scale has the most with 6 flats: b-flat, e-flat, a-flat, d-flat, g-flat, and c-flat.Of course, one could argue that other scales have more flats (such as C-flat major, F-flat major, B-double-flat major, etc), but these scales are typically notated as their enharmonic equivalent (e.g. A major instead of B-double-flat major).
