Musical Vocabulary Inquiry

I know there's a term for this, although I don't hear it much. If you're in C major, the notes you're using are C D E F G A B. The notes you aren't using are Db Eb Gb Ab Bb. What's the name for the latter collection of notes? It's something like "antiscale", but I don't think that's it. Any ideas?

C, D, E etc. are diatonic. Db, Eb, Gb etc. are chromatic. Within the scale of C major, of course.

Is that the concept you were shooting for? I have a feeling it may not be. ;)

I know it's something less obvious than chromatic. It's a name for the collection of chromatic notes in a scale.

non-chord tones?

Non-diatonic, maybe? :p

No, and no. Maybe the word I'm thinking of just doesn't exist.

Avoid notes?

Non-scalar tones.

I don't think either of those are it either.

:'(

I'm pretty sure it has "scale" in the name somewhere.

Well, they happen to form a pentatonic scale. That's not really anything to do with the "antiscale" idea, though.

In 40 years of music I don't ever recall seeing a specific term used to refer to a "set" of extra-diatonic tones except to refer to them contextually as what they are: chromaticisms and dissonant tones. It depends on which context: harmony or counterpoint.

There IS the possibility that you are recalling a term someone made up for their own use to refer to those tones. It's not unheard of. As far as I know, there is no standardized term for that set of notes. I've studied in both French and English and never come across it.

That's definitive enough for me.

Maybe it's related to the compound fifth?

well, being a talentless hack, I wouldn't know... ;)

I think that in set theory when you have six pitches(Or half of an aggregate as my teacher would force me to put it) such as [ABCDEF], [bflat Dflat Eflat Gflat G Aflat] would be the inversion. I'm not sure though.

I don't think so...

the "inversion" of ABCDEF would be something like "A G F# E D C#"

unless the word "inversion" isn't used the same in English... I think we tended to use the word "mirror" more often, but the two terms were interchangeable

I would have treated "Bb Db Eb Gb G Ab" as the complimentary hexachord to the original set.

There is a word for it though... I just can't freaking remember what it is. It's driving me nuts.
