My name is Stephen. I have this little theory in my head that I wanted to run by you people and see what your thoughts on it might be.
It's based around the concept of modulation using scales. I'll try and keep it in layman's terms as that's something I feel comfortable doing and I like to keep things simple as music theory, as we all know, can get pretty complicated. Here goes...
Lets establish a beginning: The diatonic scale... from notes to chords.
The western diatonic scale has 7 notes in it. If we started with the note of C the notes would be C,D,E,F,G,A,B. If we convert each of these notes into triads or chords they would be C, Dm, Em, F, G, Am, B dim.
This is also known as a Key. This is the Key of C.
OK so basically we play around with our chords in our Key of C for a while and everything sounds good (except for that pesky B dim... which we avoid like the plague, haha). Then we decide to modulate to a different Key to change it up a bit...
Standard modulation technique here is to jump into the 5th note or chord of the new key. So let's say the new Key is D... We therefore count five up from D.....ie (I'm going use the chords here) D, Em, F#m, G, A. So A is 5 from D, generally we add a 7th onto it so it becomes A7. We then go into the 1st note or chord of the new scale. Which is a D here and we have successfully transitioned or modulated into the Key of D. Which consists of D, Em, F#m, G, A, Bm, C# dim.
Okay so that's basic modulation 101. Great. But I started thinking about all the other scales in the world...
Then I started thinking... hey, can you use the same principle to modulate into a scale that isn't diatonic? That isn't even western?
Okay so here's a scale I like. The Zilaf scale. It's not western but it sounds Indian or Exotic... but there's a problem. It's only got 5 notes. Not 7 like the diatonic.Therefore there's no Dominant 5 note (or chord) to piggy back my way into the Zilaf Key of D for example.
But it got me thinking. Hopefully it's got you thinking too.
Thoughts, ideas anyone? Let's keep it as simple as possible if we can... Using chords in the Key of C and the modulation into D Zilaf, if that makes sense. The notes of the D Zilaf are D, F#, G, A and A#.
Over to you. It would be great to hear like minded peoples thoughts on this.... let's face it... This isn't exactly the type of conversation that people are comfortable talking about down the pub!
