If you're working from a strictly musical perspective, would it be worth using [mtof] and [ftom] so you can deal with the notes as musical pitches rather than frequencies? I know I find MIDI math a whole lot less daunting. If you're then looking for pitches that "work" with the a chord, you can classify chords by context and create some kind of hierarchy of matching notes...
This involves a lot more manual work than the approach in the paper Miller shared (you should probably just be listening to Miller here:), but it allows you to really tune stuff to what you like to hear.
Every minute I've spent playing Jazz piano is screaming "NO" at me right now.

That is a wonderful question. Here's a deep and thoughtful paper about it...

The rough answer: using theory of consonance and dissonance that goes bacy to Helmholz, Krumhansl and Kessler predicetd an answer and set out to measure whether it worked on real human subjects. The answer is, not exactly; there are places where learned expectations (from Western music theory for instance) win out over the psychoacoustical predictions.
Or in short: yes, there's a formula but your ears might not always agree with it.

Hi, i need to automatically get all the frequencies from a chord. For example imagine i have chords as frequencies in messages:
Chord1 = [195, 174, 146, 116, 58( Chord2 = [ 155, 130, 103, 87, 43(
I want to do something like this: ?Chord1.giveMeAllFrequencies And then get a list with the frequencies
Is it posible to automatically get all the frequencies that fit into each chord(all the frequencies that don't clash)?
I dont know too much about musical theory and i know i can do this by
ear ,
but is there an automatically way to get this?
I hope is clear.
Cheers
