Here are various dissonant progressions for the key of C:
6-b6-5-1-2
A-Db \ G-b-C-E
Ab-D \ Ab-C-Db-F
G-Eb \ A-Bb-D-Gb
C-Gb \ Bb-Db-F-G
D-A-F \ A-C-E-G
5-4-3-6-2
G-E \ A-D-G
F-D \ Ab-Db-F
E-Db \ G-C-E
A-Db-G \ Bb-Db-F
D-A-F \ G-A-C-E
2-5-1
D-A-Eb \ A-D-G
G-D-Gb \ Db-Gb-Bb
C-G-Eb \ A-D-G-B
5-1-4
G-D \ A-D-G
C-G-Eb \ B-E-A
F-C-E \ G-A-C-E-G
3-6-2
E-Db \ G-C-E
A-F \ B-E-G
D-A \ F-G-C-E
I learn this trick a few weeks ago...Instead of doing a normal 2-5-1, you can drop it a major 3rd and do...
b7-b3-#5
Bb \ F-Bb-D
Eb \ Bb-Eb-G
Ab \ Eb-Ab-C
(usually I move to the 5 after this, but you can resolve to the 1)
G-D-F \ D-G-B
These are extremely useful in slow songs, but you can throw them in a fast song, every now and then.
If you guys got any post away.
