Octave spiral with the first 16 elements of the harmonic series

1-2-3-4-5-4 makes that is in a lot of movies 0.0

anyone else think of lateralus

[hotamali]

love that septimal minor seventh

[GrimTheCrow]

@hotamali Hmmm... I actually tried to find out what that note was called since i liked it aswell. Thought "someone else must have noticed that there is something special about it", ended up here, saw your comment, doublechecked the tone to see if it was the same, commented :P

[arnehepp]

is it actually possible to get up to the 16'th partial when you overtone sing? it sounds a bit high to me, but I've never checked how far u I can go :-j

[skyelof]

@arnehepp Yes, harmonic #16 is definitely within the reach of overtone singing - but it takes sincere practise to get it clear and distinct. Many [i]-sounds are in the 20'es but difficult to separate as overtones. You may find the Overtone Analyzer (sygyt.com) a helpful tool.

thank you for this

[polkusin]

interesting visual representation! :) any chance of doing this with pure sine waves, also maybe a version where they keep sustaining while you add new ones to the mix?

[skyelof]

Thank you for comment!

If I eventually make the presentation you suggested it will probably not be in the nearest future. The making of these animations often become more time consuming than imagined and at the moment I am working on some presentations of polyrhythms.

... but I will bear it in mind!

[polkusin]

@skyelof wonderful, polyrhythms are a very interesting area of music as well. :) i've just been interested in spiral mathematics lately and this fits the mood perfectly. thanks for inspiration :)

Those septimal intervals hurt my ears.

[skyelof]

@alreadytaken334

Yes you have become accustomed to the minor seventh you may find on a piano or most other instruments - cultural conditioning is the name of that game.

[kratanuva725]

@skyelof I find septimal major thirds a lot more dissonant than septimal minor thirds... But anyway. Barbershop quartets often use the harmonic seventh. (7/4)

[skyelof]

@kratanuva725 Theoretically the proportion 6:7 is more consonant than 7:8, but I suppose the thing is we tend to experience the 6:7 as a minor third and by comparing it with the thirds we know, it turns out dissonant.

And the normal major second is in itself dissonant, so when we compare it with the septimal second (7:8) the latter may sound consonant.

[kratanuva725]

@skyelof I really like vicesimotertial major thirds (23/18), they are simliar in size to septimal major tihrds, but I find them slightly more connosant. (as they are slightly closer to 4/3)

Of course, septimal thirds still have their place. I find that with some timbres, they can function well as a connosance, however in other timbres, they act more like a dissonance. (And I'm not even talking about inharmonic timbres here)

[kratanuva725]

@skyelof I suppose that timbres with a louder 7th harmonic make septimal intervals sound more connosant?
