This is, in Music Theory, a "theoretical" - and rather goofy - question (I am a graduate musician).
Enharmonically, "F flat major" is E major - they are the same enharmonic key - and E major is much easier to read and play.
The notes in the F major scale are: F, G, A, B flat, C, D, E, F
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.
D-flat, F, A-flat for the triad
The F major scale consists of the following notes: F - G - A - B Flat - C - D - E - F
Notes for d minor : D F A Notes for D major: D F# A Notes for d diminished: D F# A flat Notes for D Augmented: D F# A#
The F major scale, ascending and descending, is: F, G, A, B flat, C, D, E, F, E, D, C, B flat, A, G, F
b flat, c, d, e flat, f, g, a, b flat
A Major: A B C# D E F# G# A A minor: a b c d e f g a A-flat Major: a-flat b-flat c d-flat e-flat g a-flat
b flat (half note), c, d, e flat, f, g, a , b flat (half note),a g, f, e flat, d, c, b flat b flat(half note), d, f, high b flat, a, f, e flat, c, b flat (half note), (divisi) f, e flat, d (or) d, c, b flat all divisi notes are half notes and all other notes that i have not said are quarter notes
The D-minor scale is D, E, F, G, A, B flat, C. The F major scale is F, G, A, B flat, C, D, E. So there is really no difference, other than the order of the notes.
Bb, C, D, Eb, F, G, and your major seventh is A.
To change a musical composition from a major key to a minor key, specifically from A flat major to A flat minor, you would need to lower the third, sixth, and seventh notes of the scale by a half step. This means changing the C, F, and G notes to C flat, F flat, and G flat. This alteration will give the composition a minor key feel.
