Can anyone explain to me how I would go about figuring out what key a song is?

It depends what style it's in.

Have you ever looked at a classical peice name? For instance Presto in C minor.

"Presto" is the speed at which it is played, and when it says C minor, that means the song is made within the scale(s) of C minor.

But to figure out a key just by hearing a song is something that comes with age and experience.

you need to see the piece's sheet music, and count up the sharps and the flats noted beside the clef.

my pianist friend gave the following mnemonic devices for sharps Father Charles Goes Down And Ends Battle, and Battle Ends And Down Goes Charles' Father for flats. i may have reversed the two.

the key of C has no sharps or flats. then there is some other rule which by now i have completely forgotten which uses the above mnemonic device.

anyways, this is just to let you know that there is a very precise way of determining the key a piece is in. music is very mathematical and formulaic from a theoretical perspective, and there is a defined answer for almost everything in music, including how to determine what key a piece is in.

ask someone with experience in theory and he or she will be able to help you understand the rules for finding out the key.

I make sure I'm in the right tuning, play whatever it is on guitar or piano and figure it out from there. Of course, you have to know the keys on the guitar.

So basically there's no easy way to figure out what key a song is in? You have to have sheet music and a good understanding of theory to figure it out?

Actually, that's not true...There's a much simpler way than getting the sheet music and that's to simply look. That a look at the chords within a song. Quite often (not always, but quite often) the first chord is the the key...So, to test this, let's say you had a chord prgression of G C Em D (just the first thing which came to mind).
Now, write out all the notes in G,
i.e. G A B C D E F#, now because all of the chords can be found in this scale, G is the key...if the key doesn't come from the first note, then look again....after awhile you begin to see the chords within the scale, relationships on paper (e.g. the I IV V stuff)...
There's one way...keep reading through and just ask any questions if I've lost you...Good luck!

BTW - Failing all else, just ask! There's bound to be someone near by who knows!...(Show 'em the chords first though...)

Thanks for the help!

Now, let me see if I have this right... if a certain chord progression is D Am C G, would it be in the key of D?

It kind of depends on what your ear hears when you play it. That example is in D Mixolydian because D sounds like the root, and the Am (the V of D) makes it mixolydian because it holds the minor seven of D, so it can't be straight D major. You could still say to someone that it's in D, and hopefully they would recognize the Am and know it's D Mixolydian.

Interesting... I really need to start learning some theory so I'm not so confused all the time.

When you say that Am is the V chord of D, what does that mean?

Sorry to keep bothering you, but thanks for the help.

To My Understanding But It Probally is Wrong But What Note Starts The Song Or Riff Is What Key Its In But Sometimes Thats Not True. See If You Have A Riff That Goes

A------------7--8--9----------------
E--3--4---5-------------------------

(Which is G Gb A E F Fb) Then The Key Would Be In G Right? If So Could You Do An Exsample Of When The Key Is Not The Note That It Begins With.

To answer ilovebogner10's question simply, no, not as such....
I forgot to mention the following
The I IV V (1st, 4th and 5th) of a scale are MAJOR CHORDS...the rest are MINOR CHORDS...

So, I can tell you very quickly (just through experience) that the key is G...Now I'll explain why:
The chords G C and D are the I IV V chords of the key of G, now, the Am is the II chord in the key of G, and because all of the notes are found within this scale, it's pretty conclusive...I could go into alot more detail as ekstasis16 did, however, if you're anything like I was 18 months ago it'll all be too much...If I'm underestermating you a little then let me know and I'll try and take things alittle further..
E-mail if you need to, I'll be glad to help. Just take your time and be patience, it'll all make sense eventually!

Yeah, I'm pretty confused, but I'm taking theory classes soon, so I'll understand eventually. But thanks for all the help anyways.
