Key changing in trance music

[awaky]

Hi there,

Here's my example: http://www21.zippyshare.com/v/Pg4mWEWY/file.html
The track is in A minor.

In the intro, the bassline is in A. At 30 seconds the chord progression comes in and if I follow the bassline, it does F > G > A > C.

I learn the basic of music theory for electronic music, and for me if my song is in A minor, the root note (my bassline) of my chord progression should start with A.

So, i'm a little lost...

Thanks!

No, chord progressions don't have to start on the tonic. F > G > Am > C is a very typical Am chord progression, it ticks all the right boxes note-wise. Just imagine it as Am > C > F > G but shifted for flavour. By starting below the tonic and moving up to it, it gains a sense of "building up".

Actually, I may be a bit rusty, but is that the "train hard" progression? You know, the one that plays when the runner or boxer is training in an 80's film?

OK, thanks Sendy

can change the tonal center too, so the musical mode
