		Hi GMC! Today we'll talk about the chord progression of a song of my own.



This is the first part of the song, in the second part we can listen to the complete song. In this song I use secondary 7th chord and modal exchange.



The intro is in A major key and begin with F#m7, the VI Chord of the A Major Key. Then the other chord is B7. The secondary dominant of E (Vº of the A major key), but this chord is not major because this chord come from the Am key. This is a modal exchange, like the next chord; G major. This chord comes from the Am key too, and the last one is A major. 



The idea is not to think just in one key at the moment of the composition. It’s interesting to use for example chords of the same key but in minor mode.



The verse begins with a II, V, I progression on E major key, the next chord is A major, D major from a exchange modal from E minor (same key but minor), then D minor, C#m7 (VI º from E major), the last one is C#7 (secondary dominant).



Now, at this verse, F#m7, B7, Emaj7, Amaj7 and Dmaj7are repeat but the end is change. Here appears G#7. This chord is the secondary dominant of C#m7.
