Recently I bought a 6 string bass and I've been going through Steve Bailey's work. I was disecting A Chick From Corea and now I'm quite stumpted. There is a common phrasing that continuously happens in the song, it's this chord that I cant figure out. It's either a sus4 or add11 chord. The song is in C minor (I'm pretty sure). Here's an example of the chord being used: Cm7-A#(sus4 or add 11)- A#m7- G#(sus4 or add 11). It's used as a stepping stone it seems, kinda like a sus chord. I dont believe the major add 11 chords would be suitable with any modal interchange approaches for I've looked at a few already. The notes of the (A#) chord are A#-A-Eb and the it's the same pattern for the other unknown chords. It seems like a sus4 chord but it has a major 7th which is really throwing me off. I thought sus chords had dominant 7ths. Thanks for the help!!
This seems to be a very specific voicing. And there are only 3 notes, not really enough to firmly define any chord beyond a triad (and this is certainly not a triad!) Considering the next chord is Bbm7, I'm inclined to label it Bbmaj7(sus4). But it's not a very useful label. With just that information, a musician won't play what's needed. So use notation. Chord symbols don't cut it here.
