ALL FLAT KEY SIGNATURES include a Bb, these are:
F Major/D minor
Bb Major/G minor
Eb Major/C minor
Ab Major/F Minor
Db Major/Bb Minor
Gb Major/Eb Minor
Cb Major/Ab Minor
The reason for this because the order of flats in a key signature is B, E, A, D, G, C, F. From the example above you can see that B-flat (Bb) comes first.
The key signature that has B flat, A flat, E flat and D flat is Concert A flat Major.
Assuming the key signature has only one flat (B Flat) then the key is either F Major, or D minor.
B-flat and E-flat are found in B-flat major and G minor.
well the minor scale was unfortunait used to be b flat then it was changed to e flat.
Mi is the 3rd of the scale. In B-flat major, it's D.
F major, B-flat major.
In the order of flats in key signatures, even if the melody skips the B-flat, the key would contain it, because there is no such key with only an E-flat.
When reading flat key signatures, it is the second to last flat: The order of the flats go as such: B flat, E flat, A Flat, D flat, G flat, C flat, F flat. In this case that would make A being the second to last flat, thus the key would be A-Flat Major or f Minor.
If you are talking about key signatures Bb major has 2bs but Bb minor has 5bs.
The name of the scale is whatever the second to the last flat is. For example, if you have 3 flats, B flat E flat and A flat, the name of the scale is E flat, because it is the second to the last flat.
A key signature tells a musician what key they are playing in and how many sharps or flats they must use. For example, a key signature with a B-flat would mean that the musician would play a B-flat throughout the piece unless indicated otherwise.
A flat lowers the note by a semitone. As a key signature, a single flat indicates the key of F, meaning your B should be flat. Two flats are E and B, meaning the key is therefore B flat. B, E and A flat indicate the key of E flat ... and so on.

The key signature that has B flat, A flat, E flat and D flat is Concert A flat Major.
There are two flats in the key of B flat major: B flat and E flat.
Key signatures are the sharps or flats at the beginning of the staff. To identify the key signature of a scale that consists of all sharps, look at the last sharp in the key signature. Whichever note the last sharp lies on, the key of the scale is one note above it. To identify the key signature of a scale that consists of all flats, look at the note directly before the last flat in the key signature. The second-to-last note is the name of the key signature of flat keys. However, you cannot use this helpful trick with the F Major Scale which only has one flat (B flat).
15 different key signatures exist. (no sharps or flats) = C major F sharp= G major F C sharp = D major F C G sharp = A major F C G D sharp = E major F C G D A sharp = B major F C G D A E sharp = F # major F C G D A E B sharp = C# major B E A D G C F flat = C flat major B E A D G C flat = G flat major B E A D G flat = D flat major B E A D flat = A flat major B E A flat =E flat major B E flat =B flat major B flat = F major
