so my guitar teacher gave me this 2-5-1 chord study thing to learn.
and i could play it when i was there, but i havent practised it since, and have forgot the different shapes for each one.

it goes around the cycle of forths, and looks like this

2 5 1
dm7 g7 c*7 *=triangle, not quite sure what it means,
gm7 c7 f*7
cm7...

and so on.

i was just wondering if someone could remind me of the shapes of the different types of seventh chords, eg. minor 7th the dominant 7th and the last one. plus tell me what the triangle shape means.

i was playing them in barre chord shapes, mainly on the a string, but on the e when it was nessesary.

That is awesome
you won't learn if i just give you the answers, but i will help.

the order of keys in the "circle of fourths"

C
F
Bb
Eb
Ab
Db
Gb
Cb

the II chord will be minor, the V chord will be dominant, and the I chord will be major. figure out the notes of each chord, and figure out the shapes based on that.

good luck
The triangle is 'delta' and it means major 7th (as opposed to dominant seventh or minor seventh, etc.)

CΔ7 = Cmaj7... It also often seen as CΔ
Note: Sorry if my grammar and/or vocabulary isn't very good, English is my 2nd language!

A major 7th is the same as the name implies, a 7th chord with a major 7th. So cmaj7 = CEGB

A dominant 7th is the same thing expect with a minor seventh. So C7 = CEGBb.

The most very basic voicing for a ii7-V7-Imaj7 is (in the key of G, Amin7, D7, Gmaj7)

X X X
5 5 3
5 5 4
5 4 4
X 5 X
5 X 3

That's just one you should know in your sleep.
Note that the D7 has a 9th added -- you'd pretty much never play a "naked"
Dominant 7th chord without at least adding the 9th (well, in jazz anyway...)
I'd probably play

in C, then in G:
x---x-x-----x----x---x
10-8-8-----8--10--12
x---7-x-----5--x----11
10--x-9-----x-10--x
8---8-7 ----7--9---10
x--x--x-----x--x----x
Seems like you are missing this

the C major scale
|..C..|....|..D..|....|..E..|..F..|....|..G..|....|..A..|....|..B..|..C..|

C D E F G A B C D E F G A
|......|......|......|......|.....|......|
C....E....G.....B....D....F.....A

C E G B D F A = this is how you spell chords

..I..............II...............III...............IV.............V..............VI..............VII
CEG = C, DFA = Dm, EGB = Em, FAC = F, GBD = G, ACE = Am, BDF = B diminished

You can find all the shapes for the 4 note voiced 7th chords here, including the inversions.
