Re: how to figure out the key of a song - remixing

One way to do it might be to look at the Score display. Notice now where all the "sharps or flats" are showing up (if you've initially set "key of C" which is no sharps/flats).

Those "sharps and flats" form a definite pattern which is what a "key signature" on a printed score is actually showing you. (If there are "three sharps," they are always F-C-G, and so on.) Fiddle around with the key-signature setting until most if not all of the "sharp/flat symbols" go away.

And, as someone in this thread said (many years ago, now ...) "basic music theory" really isn't all that hard. There are plenty of very good videos on the subject: Toby Rush (tobyrush.com) actually did a book of cartoons. There are really only a small handful of things that you need to know to really help you out – you actually don't have to go that deep into it to come away with some really useful nuggets. You'll find yourself actually saying, "gee, that actually makes sense!" :)

With practice, you can actually hear what the key-signature is most likely to be. Because of "physics reasons" that we don't need to dive into, the various keys sound different, and not just at a superficial level. There's a certain discernible "pull" as the lines of melody play through: "it's not just the pitch."

To Onyx509:

You can select a chord and that is then named in the PR editor.

Thanks for your reply! That is actually helpful. This way if I am playing a weird chord I can figure out what it is. It doesn't, however, tell me what key the song is in.

No, but "key" is a "chosen" value, not something you can "mathematically" compute. So if a song starts and ends with Gm and inbetween there is (among others) an F and Bb and Eb chord, well, you may choose: is it in Gm, or in Bb, or perhaps in F or even Cm? I would go for Gm, but that is by no means "the law". So I can understand why there is no such feature. The key is a choice, and such a feature would need a (rigid) formula. Because computers can't "feel" the key.

More or less you try to sense what the "1 chord," the "4 chord," and the "5 chord" feel like. Those probably indicate "the key." Songs often begin and end on the tonic – the "1 chord."
