Capos, Keys, Scales and Me - Part II
Wednesday, June 6th, 2007I have been bouncing around various web sites, forums and bb’s looking for some answers and the best resource I could find as far as this stuff goes is musictheory.net. Although not entirely geared towards guitar, it is still a valuable site to anyone wanting to learn more about music and the theory behind it.
The first thing I am going to delve into is how you go about determining the key of a song, because once you figure out the key, the scales will follow. A capo will just change the key of a song, so obviously knowing the initial key before you change the key using a capo, will help. I found various people asking the same question: “how do I find out what key a song is in” and I found many answers, most were incorrect. Most often the first answer was, find the first and last chord of the song and that will be the key of the song. Obviously this is not entirely true, BUT I would say it is true for 80% of the songs out there. The main problem I see with this approach is there could be key changes during the song, and you would never realize it. If you get called up to jam out a song during one of your friends local shows in front of hundreds of people, and the song changes keys right before your big solo……… you would look like an idiot! Believe me; I have faked my way through many solos, but once the key starts changing and you don’t know where you are, you will be in trouble. Hopefully after reading this, you and I will be able to determine a songs key on the fly just by knowing the chords or listening to it.
