Pfft.
Em; Am etc - it's all too rigid.
I like to think outside the box, as it were.
To these ends I have been experimenting with a brand new musical key I have invented.
Let me introduce you to the complexities and harmonic nuance of H minor.
There are however some new notes and scales to learn.
For the beginner, these can be a little difficult to identify and play on your particular instrument of choice as they only exist in the 5th and 7th dimensions (and in the 8th dimension on alternate Tuesdays).
If anyone is interested in learning, I'd be willing (at no expense to myself) to put together a set of informative and ridiculously expensive video tutorials.
A bit of 'normal' 3 dimensional music theory would help prospective students, as would a working knowledge of cryogenics and a few pounds of antimatter.
The key (no punishment in ten did) to actually getting a little understanding of the H minor concept is quite straightforward. In conventional western music theory, we work on a pattern of repeating notes starting with A running through to G. In the simplest terms, in my new system, instead of getting to G and starting again at A, it helps to carry on up to H.
