iim7b5 ???

[broke]

I came across this somewhere:

So far, all the changes we've made have added notes that are in the scale. There are other notes though that are not in the scale. Switching a note in the chord to a non-scale note gives us an altered chord.

Two very useful altered chords are the iv chord (notice we switched from IV to iv... from major to minor), and the iim7b5 (pronounced "two minor seven flat five"). In the key of D the IV chord is G, so the iv chord is G minor.

and after reading this a few times, i'm still confused. Just what is a iim7b5 ? would appreciate any help.

its a minor 7th chord with a flat fifth. minor 7th is 1 b3 5 b7. m7 b5 is 1 b3 b5 b7. Gm7b5 with the root on the A string would be

e ------
B ---11--
G ---10--
D ---11-
A ---10--
E ------

its sometimes called a half diminished chord. it often appear as the ii chord in a minor key. heres 2 other forms one with the root on the E string and one with the root on the D.

e --x--
B --2--
G --3--
D --3--
A --x--
E --3--

e --6--
B --6--
G --6--
D --5--
A -----
E -----

Of course its also the 7 chord in a major scale.

So it should "pull" to the chord one fret up.
