Essentially we only have 12 notes in our western system, so it's just about how we label those 12 notes the best, and I think what we have now seems to work pretty well, even if it creates confusion at times ---- Essentially you have endless frequencies in between all the notes, such as in between the minor 3rd and major 3rd, but it might not sound pleasent to your ears. We don't use those in our music, so we don't use a term such as "neutral third" or whatever we could come up with that could sit between major 3rd and minor 3rd. Those would just be described by "[number] Hz" Simply put, if we played a C major chord from the middle C (called C4) in our "equal temperament" tuning it would have the frequencies of: C4: 261.63 hz E4: 329.63 hz G4: 392.00 hz C minor would be: C4: 261.63 hz Eb4: 311.13 hz G4: 392.00 hz But you can imagine the frequencies (numbers) in between E4 at 329.63 hz and Eb4 at 311.13 Hz. We've just considered those to not be pleasent or useful currently - in "12 tone equal temperament" tuning, which essentially creates a compromise between all the notes, keys and such. The compromise that qual temperament creates allows us to play a C major chord, but also a C# major chord and have them sound relatively similar in "in tune"-ness". In a different tuning systems, such as pure intonation, it would not work when going to C# major. Here's more about it: I find it all very interesting, especially that video but even the "out of tune" stuff sounded good to me -------------------- SEE MY GMC CERTIFICATE “Success is not obtained overnight.

I think I'll stick to my continuous second order polynomial function thanks

I looked at that and my eyes went to the part of the shape I recognised first of all and thought F#5/Eb, but yeah Ebm7

Yes and no (of course I get Collier's sentiment) ...
And yes, it's Ebm7. I've been reading chord charts since 1975 and I've never heard or seen that chord referred to as F#/Eb, or more properly F#/D#. The only contextual reason that would ever be called an F#/D# would be in some type of descending/ascending bass line scenario. -------------------- - Ken Lasaine

What are those functions generally used for? Like, do they relate to your work? I don't know mate the skirt profile on a piston is quite complex, they aren't round and they aren't parallel. The profile along the skirt is something we've refined over years by looking at pistons that have been run. They aren't all the same though but our default profile works pretty well and rarely needs tweaking. Anyway back to continuous second order polynomial function. We did a batch of prototypes for a high end performance engine company. I was talking to the boffin about skirt profiles and sent him the one I had done for their pistons which was very very close to the one he had designed using his complicated computer software. He said to me, "I can see you basically use a continuous second order polynomial function with some very minor but interesting tweaks", I said, "Yes, that's about right, we tweak it where we think it needs tweaking". Neither I, or any of the other directors knew what a CSOPF was Our skirt profiles are done using intuition and years of experience. I just like to throw the CSOPF thing out there to sound like a boffin sometimes Turns out, the boffins had reverse engineered some of our pistons and had to give it a name -------------------- SEE MY GMC CERTIFICATE “Success is not obtained overnight.

Yes, I've never seen it as anything else than Ebm7 and can't make it make sense to say "Ebm7#9". I see where the confusion can come from (people thinking it's an Eb7#9 or somehow related, but not realizing it doesn't work that way with a minor chord). The problem with these groups on FB is that there are now 220 answers where about 75 of them are "wrong", i.e. saying Ebm7#9, "Hendrix chord" or Ebmin7#13, - some even with "likes" as if they were the correct answers. It can get a bit muddy and difficult to know what is right or wrong. That's not to say it can't be seen in different ways and context, but yeah... I think you get where I'm going with this. Of course, on the other hand, if you're just learning from one book and that book is wrong... that's not ideal either As a guy who really really knows music theory, I can say unequivocally that there is a 50/50 amount of confusing, bad and outright wrong information on the internet regarding this subject - and I think I'm being generous (which allows me to extrapolate that it's that way for all disciplines). I read so much horrible stuff that I don't even want to start answering it most of the time. -------------------- - Ken Lasaine
