I have not commented much on chord progressions for the songs I have posted lately. Ok, perhaps I shall do for this one.
There are 3 different parts in this song, as I have marked on the video.
Part 1 and Part 3 have the same chord progressions. It goes like this:
I –> VIm –> IIm7 –> V
The song is in the key of B. So the above progression is translated as:
B –> G#m –> C#m7 –> F#
Part 2 is actually similar to the above too, except with a slight twist. This is how it goes…
I –> III –> VIm –> VI –> IIm7 –> V
In the key of B, this is translated into…
B –> D# –> G#m –> G# –> C#m7 –> F#
With some tweaking, we can simplify it further into what you see on the video. If anyone is interested to know how this is done, please let me know.
