Only 12 Notes

The more I read about music theory and try to understand how chords and intervals are related to each other it really blows my mind how 12 unique notes (not taking into account the octaves) can give rise to such complex theories. If we walk past the domain of equal temperament (I will discuss this later) then it is even more complex.

Sticking to equal temperament for a while, I have noticed how much there is to learn by heart in order to be able to speak the language of music more fluently and to become a good player and/or singer. The music notation system is very systematic and has been developed for centuries. Some of the things you need to know are:

• The circle of fourths/fifths and the tonic parallel for every key. 
• At least the major scales in every key, both the names of the notes and the patterns on your instrument (the sixth note will give you the tonic parallel). 
• The corresponding sharps/flats in every key (at least the number of them. E.g. Eb major is 3 flats). 
• All the notes on your instrument.
• The four basic triads major, minor, augmented, diminished. All shapes in all keys on your instrument.
• If this is not enough you should also be aware of the different diatonic modes as well as the different pentatonic modes. 
• Etc... the list goes on...

This is a lot to learn and there are tools and theoretical constructs that can help you on the way. I will try my best to guide you trough all this stuff.

So what can you do with all this? Well, if you understand the theory you can harmonize a given key, you can read music sheets better (even if you sing you will benefit from this since it will help you to relate the tones to each other and easier find the right pitch for each note).

Ok, I'm a singer, why do I need to know the instrument specific theory?
Well, it is mainly twofold: Having an instrument at your side when singing after notes is a great help. It helps you find the right pitch for the notes. The other thing is that it makes you more aware of how the harmony works in the music you sing. How the voices interact so that you can more easily understand your voice and thus find it quicker. Writing out the chords in your choir notes is not a bad idea at all. We will look more closely on the matter further on. Thirdly, there is a synergy effect where you will both improve your skills on your instrument and your voice.
