Minor and major are two diatonic scales. A minor has no key signature. The key signature of A Major is three sharps, F# C# G#.
That is the signature for the key of Db. Or, it's relative minor, Bb minor.
TO FIND THE KEY FROM THE KEY SIGNATUREIf the key signature has sharps:The major key is the note above the last sharp in the key signature.The minor key is the note below the last sharp in the key signature.Ex: key signature with sharps f-c-g is A major or F-sharp majorIf the key signature has flats:The major key is the note of the next to last flat in the key signature. If there is only one flat, it is F major.The minor key is the note TWO notes above the last flat in the key signature.Ex: key signature with the flats b-e-a-d-g is D-flat major or B-flat minorIf the key signature has no flats or sharps:The major key is C.The minor key is A.TO CREATE THE KEY SIGNATURE FROM THE KEYThe sharps always go in this order: F-C-G-D-A-E-B-C (circle of fifths)If you are creating the key signature for a major key, keep writing sharps until the last sharp is the note below the key you need.If you are creating the key signature for a minor key, keep writing sharps until the last sharp is the note above the key you need.Ex: The key signature for B major and G-sharp minor is f-c-g-d-a.The flats always go in this order: B-E-A-D-G-C-F (circle of fourths)If you are creating the key signature for a major key, keep writing flats until the next-to-last flat is the key you need.If you are creating the key signature for a minor key, keep writing flats until the last flat is TWO notes below the key you need.Ex: The key signature for E-flat major and C minor is b-e-a.The key signature for C major and A minor has no flats or sharps.The key signature for F major and d minor has ONE flat (B-flat).
G flat minor or F sharp minor. F♯, C♯, G♯, D♯, and A♯ minor all have a G♯ in their key signature.
Bb. B flat has two flats, the first two flats on the staff: Bb, and Eb. Also, the relative minor to Bb, G minor, also contains two flats in the key signature; Bb, and Eb. To find the relative minor to a major key, simply count down 2 and one half steps. ie: Bb, Ab, G, making the relative minor to Bb "G minor", which also has the same key signature.
The corresponding minor key to G Major is e minor. The key signature will be the same, one sharp: F#.
There are no sharps in the key signature, but in the harmonic minor there is a G#.
The key of G-sharp minor has 5 sharps (it's the relative to B major). G-flat minor is a key that only exists in theory, because that key signature would contain 9 flats. The limit on flats or sharps in a key is 7.
G (or E minor)
Minor and major are two diatonic scales. A minor has no key signature. The key signature of A Major is three sharps, F# C# G#.
The key of E minor has one sharp: F sharp. It is the relative minor of G Major.
A minor has no key signature.
That is the signature for the key of Db. Or, it's relative minor, Bb minor.
The clef does not affect the key signature. The key signature with one sharp (F#) stands for G major. The relative minor key is e minor.
The key signature of E minor is F#.
A major key sounds more bright and cheerful than a dark, evil minor key signature. There are 12 major key signatures (C, F, Bb, Eb, Ab, Db, Gb, B, E, A, D, and G). To identify whether a piece is minor, look at the key signature. If the name of the key signature is the name of the last note, then you are in a major key signature. If it is not, chances are you are in a minor key signature.
F# minor has a key signature of 3 sharps, whereas Gb minor has a key signature with 6 flats. It's easier to use key signatures with fewer flats/sharps.
