Thanks. That makes sense to me. I've been playing for years but never learned to read, learned my fretboard properly, etc. I guess my question is more general, about the application of theory in writing an entire song. Should songs be composed entirely in one key signature? This is probably a matter of style and opinion. I want to play a more melodic style of metal...With that in mind, should a song that begins in E min remain there throughout? Or should you just play what sounds good and have theory dictate what can be played over any given part? Any input would be appreciated...
