Re: Need some help in everything DIMINISHED
Well, you play a diminished chord on every chromatic non-scale tone to connect the diatonic chords. Theres no room for one between the iii and IV and vii and I.
If you recorded this progression slow and stayed on each chord for 1 measure switching smoothly, you'll hear a real musical way to used diminished chords. Then try soloing over it using your diminished scales and arpeggios in the appropriate places.
Another great diminished exercise:
Take any diminished 7 chord shape. Heres a good one:
_______*____
_*__|____|___
___|__*__|___
_*__|____|___
___|____|____
___|____|____
Now if you move that chord up the neck 4 frets or a minor third, it is the same 4 notes inverted. You can move it up or down 4 frets and it will always be the same dim7 chord.
Now, take any finger in that chord and drop it 1/2 step. Like this:
__(*)_________
_*__|____|___
___|__*__|___
_*__|____|___
___|____|____
___|____|____
That dropped note will always become the root of a new dominant 7 chord.
Move it up 4 frets, do it again, another dom7 chord.
The pattern repeats after the 4th move, so you've just found 4 places to play a dim7 chord and built 16 new dominant 7 chord shapes off the one shape you know. Now try it using another dim7 shape, etc, etc,, the neck will open up to you real quick.
