I would say it's fundamental in itself, as it's the diatonic tritone, the tritone that creates the intense direction of the V7 chord back towards the tonic!

it's very interesting yes, there's an understanding that half-steps as you describe are almost coextensive with 'color' in scales and modes, and there's some deep connection between that chromatic color (oh hey, etymology!) and the directionality (and also potential peskiness in usage) of the two non-pentatonic diatonic notes. you all were speaking of voice leading and leading tones before, etc. that direction exists so strongly because the notes of the tritone "want" to resolve inwards or outwards by a half-step to a major third or minor sixth

mm you have perfectly characterized my perspective on harmonic color. i agree with that description, that i think of the P4 and M7 in the major scale as color notes, and the other 5 tones as "even more color notes"

But if you're trying to tell me that the tritone is a fundamental interval? When in fact, it's WAY the gently caress down in the harmonic series (harmonic number 11) -- in a direction that points away from "fundamental"!

haha just kidding (i'm doing a bit where I think there's one and only one definition of each word.)

If it's "fundamental" to anything, I would say that the tritone is fundamental to "tonal music" (if, indeed, that is its real name).

anyway i got to the bottom of why the “music theory is descriptive not prescriptive” crowd bugs me so much:

music is lingual. while there’re no set rules, sure, there ARE patterns that most people follow, that are important to being able to communicate to them and to everyone else, because so many people are used to hearing it.

music theory is like syntax. is it the same to every group of people, in every language? no. but you’re probably trying to talk to people near you, into the same movements as you… who speak a certain syntax.

this is why it pisses me off when you go “hey how do i resolve this chord” and some guy who thinks he’s being really smart says “go to whatever note you want, you can do anything”. while the sentiment is theoretically correct, what i’m asking is “how do i get this feeling that i’ve heard everywhere, that i now wish to evoke?” and so i’m being told the equivalent of “who gives a poo poo if you’re legible to other people, make whatever phonics you want”

and am i trying to say that we should always follow expectations? no, that would be extremely boring. but it’s a lot easier to break expectations _plesantly_ if you _know_ what people are expecting, and that’s what theory is. it’s vocabulary.

it’s kind of like how my favorite high school english teacher operated: swear, use slang, do whatever you want — but do it with purpose, know what you’re evoking, make sure it works.

and telling people who are just trying to write a 4 chord blink 182 song “lol just use any chord in any key to write a progression” isn’t helping anyone. they want to know how to evoke the sound of I-V-vi-IV progression with power chords in root position, not make songs with constant modal mixture

this is a strawman person you're making up to be mad at, or at least not someone who posts on these dead gay forums. nobody who actually knows theory says "just do w/e lol" unless they're shitposting, are albert ayler, or are trying to help someone who feels stifled by conventional resolutions/ isn't into the sound of functional harmony and resists learning theory concepts based on that.

what we generally refer to in a vacuum as music theory is descriptive because it's descriptive language, it helps you evaluate the consonance or dissonance of a note or set of notes relative to others preceding or succeeding it. the stylistic norms of western pop/rock/w/e music owe just as much to non-western traditions as they do to any of the canonical prescriptive parts of western music theory. most prescriptive western music theory is rules for orchestration more than anything else, avoiding parallel fifth mud in big ensembles.

i've never read any theory related text that actually instructs you on how to write music -- only guidelines to help keep poo poo sounding good.

an example is that i was wondering why something wasn't working the other day, while writing a part in sibelius. i was trying to do two piano melodies at the same time. i got to a certain note and wondered "wait why does that just disappear" and it turns out i'd inadvertantly made a consonant interval between two lines at the same time, and the lines were moving in the same note duration at the same time, so the melodies would sound good and then hit that point and disappear.

i kind of look at rules less like "i need to keep these things in mind while writing" and more like "if poo poo goes wrong, here's a list of things that might actually be the issue there" and that's a very helpful thing to me -- that way i don't get sucked into solving the problem for so long that i either get frustrated, or lose being tuned into the emotional center that led me to write music in the first place.

maybe other theory texts are just a really big dick to the reader, but i've mainly been immersed in harmony and voice leading, which has been pretty good, from what i've seen, about identifying conditions where it's okay to break the "rule" -- most often saying "...except to create melodic interest" which is pretty much right on.

if only i had the discipline to keep working on ear training in the past. i'm now at the point where i can identify intervals harmonic, ascending, and descending about 90% of the time. more than that, though, is the confidence that comes from having them worked out in my head. i've been practicing melodic dictation mentally, just from songs i hear, and it's getting really fast.

for those who have really developed their ear: did you ever get to the point where interval recognition became truly automatic and unconscious? as in, you hear a melody and could instantly transcribe it without repeating it back in your head. i assume this must be possible, but not sure if it's possible for somebody starting at my age to get there.

gotcha. yeah, it's probably too much to expect to automatically hear intervals in melodies

i'm noticing, when trying to identify triad inversions, that my ear is really sneaky. if a chord is in 1st or 2nd inversion, i will still "hear" the root note on the bottom even if it's not present (especially with close-voiced triads). it's hard to correctly sing the notes i hear because i'll just grasp at any chord tone nearby. still, it's getting easier - i can identify major triad inversions correctly maybe 80% of the time.

I might be wrong, but 440hz is the standard tuning for A so you may be looking at a C in a tuning that uses an alternate freq for A, such as A = 444hz, which many feel is more "natural" or "healing" or whatever bullshit. Not really my wheehlouse but that may be it.

I think 528 Hz is the the just-intonated minor 3rd in the key of A minor, where A is tuned to 440 Hz (the standard tuning today). 528 Hz makes a 6:5 ratio with 440 Hz.

>>> 528 / 440.0
1.2
>>> 6 / 5.0
1.2

https://en.wikipedia.org/wiki/Minor_third
https://en.wikipedia.org/wiki/Just_intonation
https://en.wikipedia.org/wiki/Equal_temperament

So, you could call it a C! (In the key of A minor, tuned in just intonation.) In equal temperament with A=440, you get 523.25 Hz for C.

I think that little harmonica tuner might be for vocalists who want to sing in just intonation. Barbershop quartet, for example.

regarding woo woo nonsense about specific frequencies being healthier:

I think this is a misunderstanding of just intonation vs equal temperament. Hearing a specific frequency on its own won't do anything special for you. However, hearing two specific frequencies will have an effect on you, because your ears will immediately try to compute the ratio of those frequencies.

Going back to the minor 3rd interval. If it's a simple ratio, like the 6:5 we get from just intonation, that will sound more "in tune" than the irrational ratio we get from equal temperament (2 to the power of 3/12). Your ear will hear the equal tempered minor 3rd as "maybe little out of tune, but its close enough". You can listen to the examples on the wikipedia page for minor 3rd, linked above.

The reason we put up with this is because it lets us tune instruments like guitars and pianos to sound "pretty much in tune" for more than one key center. This opens the door to being able to change keys in the middle of a song, or to borrow notes from other keys.

It's also worth noting that we get the just-intonated intervals "for free" from the harmonic series (aka "overtone series"). https://en.wikipedia.org/wiki/Harmonic_series_(music) This means, when we hear one note (the "fundamental"), we also hear its "overtones" too, but they are usually much quieter.

But if you pick up an electric guitar, crank the overdrive, and play a power chord (root and perfect 5th -- no major 3rd or minor 3rd) you can actually hear those overtones pretty clearly. And if you decide to also play a major 3rd on top of that, you will hear an unpleasant dissonance between the just-intonated major 3rd you get for free from the overtone series, and the equal-tempered major 3rd you are playing on purpose. For this reason, the more overdrive you use, the more likely you are to favor power chords over major triads.

All this to say, there's a kernel of truth in the idea that your ears might prefer to hear specific "unusual" frequencies instead of the ones you normally hear in modern music. But there's no evidence for "healing properties" or anything supernatural about it.

the A432 stuff is funny. the comments on some of those videos...

using this thread as my ear training diary. if i allow myself to sing the notes i can identify all intervals pretty much without fail now. i'm challenging myself to reproduce the tones in my head rather than singing - it's much harder! i was inspired by this video from hal galper: https://www.youtube.com/watch?v=y_7DgCrziI8

the gist is that EVERYONE plays what they hear in their head. if your playing is muddy, or quiet, or imprecise, that means you're hearing it that way in your head. so, i'm now cultivating a stronger, more vivid aural imagination.

one concept i've really stuck with, from the 4 tonic stuff, is what i like to call tritone sub .5 and tritone sub 1.5 (going a single or three minor thirds, instead of the 2 for the tritone sub).

these subs work pretty universally, and you can mix and match them fairly freely. they're more dissonant than the tt sub, but you can still tread back to safe water pretty consistently.

thanks for posting this, i have made my first pass thru it. the audio examples are very helpful.

next, i need to try following along on guitar. maybe then, i will have something interesting to say about this.

i will say that his 4 tonic stuff seems to be the same thing that Barry Harris has to say about the fully diminished 7th chord. I always wondered "can't you do something similar with the augmented triad, since it's symmetrical in the same way that the diminished is?"

it seems that there is -- that's what he calls the 3 tonic system! But i'm still working on understanding it.

For now, i'm just thinking about how the b6 degree is both the bb7 in the leading tone's fully diminished and the #5 in the tonic's augmented triad. For example, in the key of C: that diminished is B D F Ab, and the augmented is C E Ab.

I'm learning harmonica so I'm starting to learn about song keys. Here is a musical circle I can't square:

Example, Afternoon Delight is in the key of F according to the internet, but there is an A Major chord in it. A major is not in the key of F. What other keys?/chords? are allowed in a song that is in a certain key? Relative minors? I don't know.

Rock isn't primarily diatonic like the Western common practice where a lot of this vocabulary originated is: it is descended from blues, which has its own distinct, though related, tonal logic. Perhaps a more proximate justification is, well, both of those chords are easy to play on the guitar, and the guitar is a cornerstone of blues and rock music.

A is the III chord in F, It's basically a brighter version (only one semitone away from) the iii, a chord that is in F major: Am.

The third and sixth chord degrees are called mediants, they sort of act like prolongations of the tonic. We call these altered non-diatonic chords (the ♭iii, ♭vi, III, and VI chords in any given key) chromatic mediants.

(I wrote several paragraphs on mode mixture and how it's square-peg-in-round-hole for rock music before I realized the chord was A, not A♭. :smith:)

Looking at https://www.chordinatr.com/#/tonic/F/degrees/I,II,III,IV,V,VI,VII

I guess I never noticed the far left where it says that I to VII are chords. I thought those were just notes in the scale? I guess I don't understand the difference between A being the III chord of F not being in the key while Am is?

It hasn't got six strings, but it's a lot of fun.
So people do the Roman numeral notation slightly differently, that site doesn't do it this way, but the way I see most often (and that makes the most sense to me) is:

* The numbers are relative to the major scale. So, numerals with no accidentals mean the root of the chord is that degree in the major scale, e.g. the C minor scale has the ♭III chord built off of E♭, and C major has the iii chord built off of E.

* Lowercase numerals means the chord is minor, and uppercase means major. (diminished is lowercase with a little ring e.g. viio, augmented is uppercase with a plus sign e.g. III+, usually.). You can add extensions and specify inversions and the like from there.

So, with this system, the major scale creates the chords I ii iii IV V vi viio, and the minor scale (which is just the major scale starting from the sixth degree, e.g. C major and A minor contain the same notes) creates the chords i iio ♭III iv v ♭VI ♭VII.

The A chord has the notes A, C♯, and E. C♯ isn't in F major, but C♮ is. You can cycle through all the diatonic modes with F as the root, from Lydian to Locrian, and you'll never get an A chord, hence the chord is non-diatonic. You can get A♭ (the ♭III), Am (the iii), and Ao (the iiio), but not A (the III).

So, with this system, the major scale creates the chords I ii iii IV V vi viio, and the minor scale

I feel like this is a terminology issue I'm having.
I understand that the fifth chord in F major scale is C major. Is that website just showing me what the root note of each number is? Or is "chords" used to describe different things?

yeah! this website is goon-made, so we can ask the author about it. "Gruffalo Soldier" is the name of the author.

lets look at the numbers you're talking about by quoting an earlier post:

Looking at https://www.chordinatr.com/#/tonic/F/degrees/I,II,III,IV,V,VI,VII

I guess I never noticed the far left where it says that I to VII are chords. I thought those were just notes in the scale? I guess I don't understand the difference between A being the III chord of F not being in the key while Am is?

you're right. in the context of the app, those roman numerals (I,II,III) refer to both "chords" (like you saw on the left side of the UI) and "scale degrees" (like in the URL). Tweezer Reprise did a great job talking about how we use roman numerals as shorthand for chords, and how this app doesn't follow those conventions (i.e., it shouldn't always be upper case, the minor chords should be lower case).

It's more conventional to use arabic numerals (1,2,3) to talk about scale degrees. It seems to me like you are getting confused because of a blemish in the app -- it should be using arabic numerals to specify which degrees are in the scale! If it must use roman numerals, the capitalization should reflect the presence of a minor 3rd or major 3rd!

I'm learning harmonica so I'm starting to learn about song keys. Here is a musical circle I can't square:

Example, Afternoon Delight is in the key of F according to the internet, but there is an A Major chord in it. A major is not in the key of F. What other keys?/chords? are allowed in a song that is in a certain key? Relative minors? I don't know.

there's a one note difference between the A minor chord (diatonic to the key of F) and the A major chord (not diatonic the key of F). That "borrowed" note is Db or C#, which is the flat-6 degree of F.

We can ask the app to include that borrowed note as a scale degree, and the A major chord appears:

https://www.chordinatr.com/#/tonic/F/degrees/I,II,III,IV,V,bVI,VI,VII

It's hard to answer your question "which other chords are allowed". Whether it sounds good or not depends on what the prior chord was and what the following chord will be.

In this song, Afternoon Delight, the A chord is a "passing" chord -- we quickly move off of this A chord onto a more stable Dm chord. With a "passing" chord, you could jam just about any chord in there. The point may be to generate musical interest by creating a little dissonance and then resolving it.

EDIT: listening to the song, I can hear what the A major chord is doing. https://www.youtube.com/watch?v=wu1UXCdyNo0&t=51s. The Db or C# in the A major chord is just part of a chromatic line in the vocal part, going C, Db, D. We can still call it a "passing chord," but now I think the point of it is to create this chromatic line.

Thinking about this a little more: I bet your harmonica is the "diatonic" kind meaning you can't play the b6 note at all. When you are playing afternoon delight on your diatonic harmonica, you're gonna have to make something up to replace the Db or C# from that A chord that you can't play!

Since it's a passing chord, you can probably get away with just about anything here. It would be good to experiment.

If you DO have a chromatic harmonica, then you can play the note, but those are rarer to find, and more difficult to play.

EDIT: if we can't get the chromatic line by playing C, Db, D.... i find C, A, D to still work. C, F, D also works. See how those go on the harmonica?

EDIT2: it has been brought to my attention that it's possible to "bend" notes on the harmonica, such that maybe it is possible to get this Db? Need a harmonica expert to come in here and post!
