the last set you did was based on 7/4, and IMO it doesn't really fit, since nothing else in your scale has any relation to harmonies with any multiple of 7 in it. +2 chords are good, it's just interesting to see them lacking a 7th, because in classical harmony usually +2 is in the form of a 9th chord, and that almost always has a 7th too, or sometimes as a suspension, which makes it not really a chord.

Glad I could be of assistance.

It's like listening to Charlie Brown's teacher to me.

Not a huge surprise, though: I'm guessing I literally have the least musical talent of any person who has ever posted here.

Okay, so it is uncommon to use a chord based on the 7 of the scale? I know none of the other chords have a 7 in them, but if I was playing a melody in this scale I would use the 7 all the time, and I might every so often want to play that last major chord.

If you were just playing acsending and descending major/minor triads in C minor, would you play a different triad when you hit the 7th as a chord root? I thought I had the theory right, or are you just saying that artistically you would simply not play a triad there because you just wouldn't like it?

I love +2 chords, though I usually remove the 3rd (except I sometimes leave in the 3rd if it's minor, but in practice I think I've only ever done that over the root note of the scale). I do also love +2 with a flat 7 in a chord, but I was trying to come up with a set of notes that could be fit into two octaves on a piano (as it is now I have some leftover keys which may end up becoming interesting 1/4 tones), and if I added in flat 7ths I think it was going to take up too many. I may still end up adding them though... I really should, I love using them. (am I nuts that I would pretty only ever use flat 7s?).

Thanks for your comments, I really don't know what I'm doing yet, but JI has me enthralled!

Well, it is and it isn't. It's definitely odd to see it out of the blue, with no other harmonies built on 7, and in such a tonal system, it would sound rather out of place. It's less odd to see it in systems with chords built on 7, like the septimal minor chord (6:7:9) and especially the dominant 7th chord (4:5:6:7) and a few others.

The seven that you say you use might really be just an out of tune 9/5 or 16/9, especially if chords are built on them. I would probably, if I were playing triads, have it be built on 16/9 - so you'd have a major chord of Bb-16/9, d- 10/9 and f- 4/3. Probably.

Hmmmm... much thinking to do. What I really need is a keyboard and some software that will allow me to tune notes to exact root frequencies and assign them to any key (not just any key per octave, since I'll need a couple octaves of keys just to get one octave out of this idea). Money money money... I haven't found any keyboards that do this yet either, very frustrating.
