(Make sure you've read part 1 first...)
In this part, we'll look at several steps/approaches you can take to get better and quicker at deciphering chord progressions.
First tip is to listen to the song you want to learn on HEADPHONES, preferably good quality headphones. This confers multiple advantages – generally, you can hear in finer detail and guitar parts are often panned in one speaker or the other, in that case you can remove the other side so that you can more clearly hear the guitar. Listen as focused as possible, without your guitar and with your eyes closed.
