Like really tight jeans, key changes can be quite difficult things to pull off if you’re not sure what you’re doing. While it won’t do anything to help you get your trousers off, my 12-step Easy Guide with accompanying video, found on page 74 of the June 2014 issue of Computer Music, does explain the basic theory behind key changes. I then go on to show some real-world examples, breaking them down to illustrate how they’re constructed.
So if you’ve ever wondered how to achieve the leap from one key to another without making virtual question marks appear above your listeners’ heads, check out Computer Music 204. It’s also got a lot of other good stuff, written by other people, in it too.
