I want to find out usages chords of a song

After hearing a song I want to find out its usages chords but i can’t assume which will right chords. Such as, C major scales song’s a tune stand on C note then am I define it C chord/E chord/G chord? (I know that C= C E G & known about relation also). What is the rules to fine out chords from a song.

Ahem... does anybody speak that language?

mmm yeah I'm confused too by your english ....

you say that you want to know what chords are used in a song you heard ? ...

post the link to the song and we'll tell you

or you mean about chord inversions ?

like "C E G" is C major, E G C is also "C major" 2nd inversion, G C E "C major" 3rd inversion ...

if I didn't understand, try to explain us better what you are trying to "find out"

I think he/she wants to figure out the chord progression of a song and knows that it is C major. Perhaps wants to know if there are methods to finding out the progression too. Just a guess...

u r right, i want to know methods to finding any song's chords.

Well there aren't any methods really, you just need to have a good ear... or try out some familiar progressions like I-IV-V etc... the chances are that most rock and pop songs will in some way utilize this progression and also use the blues scale which is root-minor third-forth-flatted fifth-fifth. That in itself can give you some ideas about progressions that can be used.

But I believe that it is best to train your ear to recognize progressions and chords which is done trough playing and really paying attention to what you play and try to memorize it.

You wanna be super-safe?

At each bar, pick out the meaningful tones. These tones will outline a triad, a three note chord in thirds (ie, CEG, BDF#). These notes will likely be longer notes in the bar. Attention should be paid to beats 1 and especially 3.

An extremely safe melody will hit the V chord at the climax of the melody, but since it's 2009, you can't assume that.

However, songs without melodies like most* modern (post-1970) rock (ie riffs) are simpler, and usually refer to the scale used for the riff.

You wanna have fun? Find something that supports the melody, not reinforces. Chords that are triads that have the melody in extensions of the chord (CEG under say a melody like B-A-D+F, say...) are a good place to start, but any interesting relationship will work -- that's where your job comes in :)

Well there aren't any methods really, you just need to have a good ear...

ear and Harmony knowledge ... that's all....

you don't play piano ?

Though this is more work than what is needed to find a chord progression of a song, you can develop these skills over time if you practice. This website I found helpful when I took music theory.

If you are lucky, good with google and are desperate of finding the progression, there is a possibility the chord progression is online somewhere. No guarantees though.
