Tips on Composing a Horror Song

One day, I was in the mood of composing songs, but I have already forgot the rules of cadences which I've learn during my college. I just try an error, by listing the alphabet with all the minor, and diminish chords. Because my music teacher told me before that, minor and diminish chords make you feel discomfort. Here is my own way of creating a horror song. 

1. List Alphabet A to Z with chord of minor, minor 7th, and diminish 7th. As the alphabet increase, the chord also increase by semitnone.

A: C minor

B: C# minor

C: D minor

D: D# minor

E: E minor

F: F minor

G: F# minor

H: G minor

I: G# minor

J: A minor

K: A# minor

L: B minor

M: C minor 7th

N: C# minor 7th

O: D minor 7th

P: D# minor 7th

Q: E minor 7th

R: F minor 7th

S: F# minor 7th

T: G minor 7th

U: G# minor 7th

V: A minor 7th

W: A# minor 7th

X: B minor 7th

Y: C diminish 7th

Z: C# diminish 7th

2. Make a sentence for this Song.

Eg: I Love you, Do you love me?

3. Follow the chart:

I: G# minor

L: B minor

O: D minor 7th

V: A minor 7th

E: E minor

and so on

3. Then Play the chord, each chord for a bar. Then a horror song done.

4. I have made one using Garageband Software, Happy trying!
