That's the basics for most rock, pop, and straightforward jazz. It doesn't "fit" the pattern your music is playing. You can go to any website that lists the chords for key of A and you'll see it does not have Bb Major and C Minor within the 7 chords. You also previously considered that it might be key of A. A process of elimination to find the best pattern that fits the puzzle. That's it, you've figured out the key of your song. One of them sounds more "correct" when overlayed on your song than the other. Those are the 2 patterns you need to consider (the other 10 patterns (keys) you can ignore). One of them is key of Bb Major (or its relative G minor),Īnd the other is key of Eb Major (or its relative C minor). (Your chords use inversions for voicing which disguises things a little but that's easy to figure out too.)Īnyways, out of the 12 "patterns or keys", there are only 2 that have those 2 particular chords right next to each other. In your song, you have a repeating motif of Bb Major to C minor. The other 12 or 72 are "relative" so it's not adding any new patterns for you to "fit" to your song. Just ignore all those extra combinations for now.) In terms if just figuring things out, you can simplify the "patterns" down to just 12. (Some would expand it and say there are 24 "patterns" or "keys" because of 12 Major plus 12 minor and some go farther and say 84 patterns because of 7 modal keys multiplied by 12.

Since there are 12 notes in scale, the pattern you see above has 12 versions. The basic chord structure "pattern" for western music is:ġ Major, 2 minor, 3 minor, 4 Major, 5 Major, 6 minor, 7 dim It's like solving a crossword puzzle with a few missing letters but it's easier than crossword puzzles. Solving the key of the song is simply finding the " named pattern" that fits the unnamed patterns you see in the music. If you can "work out a solo" that avoids notes that "clash" or can "figure out a solo" from a song, you already have 99% of the knowledge to determining the key of the song. In any case, the good news is that determining keys is very easy to learn if you have the curiosity to do it. It doesn't seem to be a prerequisite for making music. There are several famous musicians out there that get by just fine without knowing how to find the key signature of songs. , but as for definitively working out the key of stuff I write myself, I find it far harder than, for example, difficult time signatures or working out a solo - I'm fairly sure I can't be alone.
