First of all, I'm a self taught musician. I have a basic understanding of music, and I can play piano too. I understand the theory behind diatonic scales and how the harmony works. I have learned the major, minor, diminished, and augmented chords, and inversions too, as well as the basic 7th and 9th chords.
Now I want to compose music for a short film. I have already planned to get what plugins I needed for my DAW, and I have even come up with some tunes which I'm really happy with.
But because I'm composing for a film in the thriller genre (sort of), some of the tunes don't fit in the normal major/minor scales. I understand that's how film music works sometimes, but I'm still scratching my head (maybe because of my OCD lol).
For example:
- the melody notes (C, E, D#, C#),
- with the chords (C minor, D# Major, C# minor)
A second example:
- the melody notes (G, F#, D#, D),
- with the chords (G minor, C minor)
These are just some simple examples to clarify.
When I play all that, for me it sounds good and flows well with the scene, but my mind really overthinks about it: "What scale is this even?". The melody notes are relatable to the chords at least, and most of it and sounds good too — nothing felt off or unrelated.
So I'm really worried, am I doing something wrong? or is there no rules as long it sounds good together?
