I would say that that is not true at all. A chordal approach to other types of music isn't uncommon. However, it was stated that in rock one can use the scale approach (running scales/riffs/solos or entire songs based on scales) while in jazz scales arent mandatory and can take away from the musical features of jazz. With jazz (save avant-garde/free jazz, but even then...) I found that the use of such chordal approaches is ideal as the notes you use (how ever many you chose) should be of high quality within the respective setting in order to express whatever you wish. Now I'm not saying that you have to play certain notes in certain settings (hell, i've only been playing jazz for about 2 months now with a combo and i often throw in whatever notes are convenient), but if you try to think of scales that work with chords, then you will end up playing through the scale, and no matter in what jumbled order, it usually doesnt sound that great and can quickly become stale. The reason you can play notes not in the chord (the triad or chords with more notes) is to add colour to the chord and for convenience...but also because there are some other chords which work with the one you are using which sound good, and sometimes these notes fall within those other chords. This is a simple example as I have absolutely no previous theory education, myself...this is just what I get from listening to jazz and playing with songs (w/ lead sheets of course
). Anyway, I hope this clears some things up, but I'm sure the more advanced players and musicians can ellaborate or correct me.
