Have you ever thought of why some songs just aren't interesting? One of the most noticeable techniques that keep people wanting for more in your songs is a key change, and it's something you'll need to learn if you want to go somewhere with music.
(If you're not sure what I am talking about, it's okay - everything will be explained in the short video below).
Of all the concepts in music theory, it seems that modulation (the theory behind key changes) tends to be one of the most confusing for new students. Part of the reason for that is comes down to guides making students memorize different changes that work, rather than showing them how to find out their own.
Any teacher can mention to you this list of technically correct method to modulate - but the list alone is useless:
Simply move to another key without setting it up. But this one doesn't usually have a great effect, generally sounding choppy.
Move up or down a cadence in the key you're playing. It's usually done by playing the fifth chord in the new key, followed by the first chord (examples can be found in the video).
Bridge to a new key by finding a chord that belongs to both keys.
Is that a bit easier to understand? I guess not! If it doesn't make sense, it's all good - you're not the one to blame. In fact, it's not really possible to learn modulations "in theory".
The best way to learn is to hear modulation in action. This is why I'm keeping this one short and not using charts, diagrams, or theoretical "rules" for you to memorize; instead, I made a quick video. Watch it below to hear a number of examples.
Was there any one of these examples that stood out to you? Try incorporating them into your own songs!About the Author:
