I IV V Progression

It is the basics of a Major Chord progression.

I - iv- v , for example would be a basics Minor chord progression.

There are many formulas of chord progressions in between, but im not going to go into that.

Reggie is right by the way.

There is a wonderful, easy to understand book called The Idiots Guide to Composing and Arranging. It gives you great information for different chord progressions. Common jazz chord progression is ii V I.

Depends.

In a I-IV-V you want just that - the I,IV, and V chords of a key.

So, in D Major: D G A
In D Minor: Dm Gm Am (or A if it is harmonic minor)

For ALL of the chords in a particular key, that also depends.

D major has two sharps - F# and C# so the extracted chords for D major would be:
I: D
ii: Em
iii: F#m
IV: G
V: A
vi: Bm
viidim: C#dim

for D natural minor there is one flat - Bb, so the chords would be:
i: Dm
iidim: Edim
III: F
iv: Gm
v: Am
VI: Bb
VII: C

With secondary dominants, harmonic and melodic minor, modal tonalities - you can get deeper and deeper into this stuff.
