I don’t see how one interval can be more ‘natural’ than another.

With just intonation a perfect fifth, for example, has a frequency at a ratio of 3/2 of the root note. This is regardless of key. As such, the relationship between the pitches is the same in all keys, regardless of any absolute frequency values

Yes, but just intonation is specific to a key - just intonation in C major does not use the same pitches as just intonation in E. If you play an instrument tuned in just intonation in a different key from the intended one it can sound really bad.

no no no ! Equal temperment is the bodge.

Yup, it is but, RichardT, each key had slightly different intervals only when played on an instrument tuned with just intonation in a single key. Not sure I'm using the right words here*

The natural doh ray me ... scale exists for each of the base notes and are harmonious to the ear.

Yup, it does, it's also called 'just intonation'

The equal temperment scale is based on mathmatics that minimise the frequency error for each of the scales when they are compressed into 12 notes/frequencies.

Just intonation has mathematical intervals too but based on ratios of the root note which results in the semitones not being exactly the same.

[fretless instrument & gypsie jazz players stop laughing now !!!! ]

(stifles a giggle behind hand)

each of the scales therefore has differnt errors, giving different emotions & qualities.

In just intonation all the scales are identical, provided they are played on an instrument tuned for that specific scale, a melody in Bb will sound awful on an instrument tuned with just intonation in C and vice versa.

Modern synthesizers allow for the different rootnote/scales & its on my list of things todo once ive mastered the bigger picture of choosing the right notes, playing them in the right order & at the right time.

True,

in the mean time [normal times] listen to the Academy of ancient music, playing authentic scales on authentic instruments.

Hmmm

"If it isnt baroque dont fix it "

But it was so somebody did :D

* An instrument tuned in C Just will sound perfectly in tune when playing in C but more out of tune the further around the circle of fifths you move keys. An instrument tuned to an F#/Gb scale (C still = C but the scale intervals are calculated starting from G#) will be perfectly on tune playing in G# but 'orrible playing in C.

I tell you what though, this conversation has become incredibly scientific for a vocal effect that actually makes a person sound like a frog in a bucket trying to sing the Aria from La Boheme. In my view NO amount of discussion as to which key is better for Autotune will improve the end result.

And so for that reason I say Fmin9th ...

Ah - Yes, that’s right, I wasn’t clear, I meant that on a single instrument set to a particular tuning, each key would sound different.

If different instruments were all tuned to different root notes using the same tuning system, then they would sound the ‘same’. But if these instruments tried to play together, I’m not sure how good the result would be!

Yes, and that’s the whole point isn’t it. Just intonation maintains the ‘correct’ ratios between intervals, but can only accommodate one key. The tuning has to be changed in order to maintain the ratios in a different key. I.e in order to sound the same.

As I said, a perfect fifth is a frequency 2/3 of the root, regardless of key. That relationship stays the same, and the tuning is adjusted to accomodate the key.

In other words, the intervals are the same as long as you’re tuned to the correct key.

Well, in that case, I think we agree!

Not atall, as I said above I was talking about individual instruments. So for example an organ would sound different in different keys, as would a harpsichord tuned to, say, mean temperament in C.

Also if a piece included sections in different keys the intervals would be different in those different keys whatever tuning was chosen. String players would naturally compensate for that to some extent, but not all instruments can. So there would be differences.

I’m thinking the Spinal Tap reference.

In other news, it was nice to see the return of Alanonguitar a little earlier in the thread!!

You're perfectly correct of course - what I wonder is if certain specific frequencies are perceived slightly differently by our cognitive processes and thus may produce slightly different emotional results when used in music.

The idea sounds a bit ridiculous initially, true. But in the end music is the result of frequencies of moving air as interpreted by our brain, which is often not that linear. If that were the case, a progression made by chords built over identical "just" intervals but starting at different root notes might feel a little bit different.

I don't buy for a second that something as little as a few Hertz has a significant impact (like the funny debate about 440Hz for A), but does a C Am G where the chords are built on just intervals feel different to a "just" F Dm C ? Does it convey a different emotion?

Probably not. But I've never tried.
