I have overlooked this for the longest time, I usually add oscillators together at either the same frequency or just octaves apart.

So a common method is to add an oscillator 7 semitones above another to get a harmonious fifth and that's really cool.

What other ways can the semitones on oscillators be useful, do people ever try and add a third or a fourth for example, or anything else you can think of?

Cheers!

Sure you can go for the harmonic 3rd or 4th.
The other nice trick is to add some cents variation between the two.

For the deep wobble basses you can put the other osc at 1 semitone above or below.

That's all I have.

I always just did what was sounding good, and it almost always ended up being 5ths everywhere.

Microtonal is another option to explore, detuning + - small amounts is sort of microtonal I guess

A perfect fifth is 7 semitones plus 2 cents.

A two-semitone interval can be heard in the rhythmic synth pulse that plays throughout the score for The Dark Knight. It really works well to build tension. You can hear it in the beginning of “I’m Not a Hero.”

Yes I will have to start experimenting with 3rds and 4ths and then look out for them when I am listening to music, the 5ths seem very popular but these are less so as far as I can tell.

Not sure I want to go into microtonal territory but those 5ths certainly are concordant and popular for a reason. I worry how it affects musical theory as it can reinforce notes out of the scale but this is for another discussion I suppose.

That's just crazy, any idea why this is so? :o

Yes for sure, listening now and there's great tension. Good ol' Hans. I thought that tension was reserved for one semitone intervals so it's interesting hearing about this, cheers.

Because the equal-tempered scale does not hit the "perfect" intervals. A 5th is the frequency ratio of 3/2, which is ~7.02 semitones, a 4th is 4/3 (~4.98 semitones).

Well it certainly sounds more harmonious with those 2 cents, I think I'll leave the complexity of it to those in the know, thanks for explaining :puf_bigsmile:

microtonal chord.zip


There is a quick example to play with! It's already got some detuning to make the chord sound a little microtonal. Then you play the bassline and make chord progressions by automating semitone/oct.

You can find some really interesting microtonal music on youtube, which use more advanced methods and which are truly microtonal and sound otherworldly (not always good)! Very interesting, but it's a whole other rabbit hole to fall into. :-)

Careful now, you'll start casting spells
