To go from a major key to a minor key in music, you can change the third note of the scale from major to minor. This alters the sound and mood of the music from happy and bright to more somber and melancholic.
To find the relative major of a minor key, you can go up three half steps from the minor key. For example, the relative major of A minor is C major.
To find the parallel minor of a major key, you simply need to go down three half steps from the major key. For example, the parallel minor of C major is A minor.
The chords that typically go with a minor key are the i, iv, and v chords.
The chords that go with C minor are C minor, D diminished, E major, F minor, G minor, A major, and B major.
The chords that go with the key of A minor are Am, Bdim, C, Dm, Em, F, and G.
To find the relative major of a minor key, you can go up three half steps from the minor key. For example, the relative major of A minor is C major.
To find the parallel minor of a major key, you simply need to go down three half steps from the major key. For example, the parallel minor of C major is A minor.
The keys of C major and A minor have no sharps or flats.
Lighter, happier, and bouncy music go with major scale. Dark, scary terrifying, and sad music go with minor scales.
You cannot transpose from a major key to a minor key. You can change the key of a piece, but transposition must be either major or minor. Actually you can transpose from major to minor but it won't always sound right. First write down the chord functions for each chord in the major key (eg. I ii iii IV V VI viio). Then write down the interval of each melody note (eg. C over a G chord is a perfect fifth). Then for the minor key write out the chords using the chord functions as your guide. So if C was in major key, acting as I chord, in the key of Am you would have an Am chord. In minor keys we use a mixture of natural minor, harmonic and melodic minor which affects which chords you will use in your minor key. For example, in the key of Am the V chord might be E major (not E minor) using the G# from the melodic minor scale (or harmonic minor scale). It has a stronger resolution. For the melody use minor intervals instead of major intervals - so use minor 3rd instead of major 3rd, minor 6ths and 7ths. So if you had an E melody over C chord in major key you would have C melody note over Am chord. This doesn't always work but can get you started.
Start in C major, parallel minor is C minor, relative major is E-flat major, parallel minor is E-flat minor, enharmonic respelling is D-sharp minor (which has 6 sharps).
"That would be A minor. Go a minor third below the tonic of the major scale to find the relative minor." Technically, there is no relative harmonic major to the key of C Major. The relative minor scale of C Major would the natural minor scale of A. A harmonic minor scale raises the 7th note of the scale a half step, giving us G#, which is not in the key of C Major.
C Major, zero flats and zero sharps. The minor scale with the same number of flats and sharps is A Minor.
E flat. The way to figure it out is to go three half steps up from C. So the major key for D minor would be F, the major for E minor would be G, etc...
The chords that typically go with a minor key are the i, iv, and v chords.
The chords that go with C minor are C minor, D diminished, E major, F minor, G minor, A major, and B major.
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).
