I'm trying to deconstruct a song written in CMin (according to a website).
I know how to find the notes within a key and have been able to transcribe a few lead riffs but the chords seem weird to me; would it be a proper to assume that all of the chords in the song are written in the CMin (so I could simply use a trial and error approach till I get it right, sounding well)? Or do these key changes change the overall song key?
Is there an overall song key and within that sub keys throughout the song?
If I play a CMaj sustained, I know I can noodle around on the CMaj keys and it will sound good. But if I then play a DMaj chord (which adds C# and F#), am I now playing in the key of DMaj?) If I played a DMin chord though (which is found in the CMaj key), am I still in CMaj or have I now changed to the key of DMin?
Am I making any sort of sense?
