I've read that dominant
7 chord drives toward some kind of resolution because the tritone between the
b7th that creates some form of tension that craves to be resolved one of these two ways :
This concept can be used to create the classic
I, or sometimes
vi (or others resolutions I guess)
Question : Extending this concept to other tritone chords, can a
maj7sus4 chord be used the same way ? Is there some notable usage of this chord this way (i.e. as a way of creating strong resolutions) ? In other words, Can a
maj7sus4 can be used as some kind of "secondary dominant" of another chord ?
Of course, the resolution rules would be different, as the tritone is not in the same place in the chord (for instance,
I would work I think).
