Title: Ionian tritone subsitution over III7 chord - Preacher Chord run
Post by: B3Wannabe on June 10, 2009, 12:29:35 PM
In this example, I'll be using the major scale (Ionian mode) of the key a tritone interval (http://en.wikipedia.org/wiki/Tritone) away from my main key, placed over a III7 chord, to lead to a dominant (http://en.wikipedia.org/wiki/Dominant_seventh_chord) IV.

Because I used the key F# in my last example, I'll use it here also.


Key:
F#, G#, A#, B, C#, D#, E#


Now, since we're using the key of F#, our tritone interval (http://en.wikipedia.org/wiki/Tritone) would take us to the key of C.


Related Key:
C, D, E, F, G, A, B, C


We'll take the related scale and play it over a dominant (http://en.wikipedia.org/wiki/Dominant_seventh_chord) III in the original key.

A#-D-G# / C, D, E, F, G, A, B, C


Use this to lead to a dominant IV (http://www.learngospelmusic.com/forums/index.php/topic,66967.0.html).

This is a preacher run?!?!

When I get home I'll DEFINITELY try this out.  It's different from any preacher run I've ever seen.

Yep. It's the tritone interval that makes it stand out and sound "minorish".

I usually end this with a ii or IV chord over a IV7.

B-D#-A / D#-A#-B or D#-F#-B


That way, the C of the run becomes a leading tone for the B in the IV chord.
