Guys,

Is there an easy way of working out what chords are in what key?

eg. Key of C major has the notes C-D-E-F-G-A-B-C.

I understand how to get the first chord which involves the 1st 3rd and 5th note of the scale (C, E and G) aka the C major chord

How do I get the 2nd chord 3rd chord and so and so forth. I do have a book that tells me what chords are in what key but I would like to be able to work it out for myself and improve my theory knowledge.

Thanks guys and gals

Matt
