Wow.. didnt realize diminished chords really put in the work!

[@michaelkeithson]

😂 Yep, gotta love those diminished chords holding everything together!

[@NickWeissMusic]

A little tangent on the diminished talk: the vii dim7 chord is interchangeable with the V7b9 chord. Exactly the same chord, with a V note in the bass. Conversely, if you play a V7b9 chord and delete the root, you’re left with vii diminished 7. E.g., G7b9 without a root is Bdim7. That B diminished chord sounds cool over G7b9 and is easily repeatable.And the half whole diminished scale starting from the V note sounds really good, and it’s also fairly easy to play over this sound. Literally half note, whole note until you hit the octave and it starts over. For a G7 leading to C, it’s G,Ab,Bb,B, C#, D and so on. Yes it has 8 notes if you’re finding that confusing lol, I certainly did at first. You only need to learn 3 of them because the pattern starts over once you’ve gotten to the minor 3rd. Here’s a very practical way to think of half whole diminished: take the vi dim 7 chord, which is 4 notes, and give every note a half step leading tone below it. That’s the 8 note scale. If you use these chromatic leading tones to the chord tones of vii dim7 and mix it up a bit, you sound like Stan Getz, ta da! Dominant b9 is a bebop staple especially in any V dominant chord leading to minor 1. Half whole diminished is kind of a dark bebop dominant scale to me, with very little to remember ;) . Btw, vii dim 7 naturally leads up a half step to minor 1, not major, it’s just a darker version of V7 to 1 minor, used often in classical harmonic minor music. You can absolutely use V7b9 (or vii dim 7, again, same basic chord) to major 1, but that’s the kind of thing the band’s going to want to agree on, not exactly interchangeable sounds. In other words, you don’t always want dark V7b9 chords leading to major 1’s, as it’s nice to have simple major sounds to contrast with dark, more complex minor sounds. Learning to use diminished chords is weird but useful, and all the greats use it. It’s generally easy to do physically, or at least, it’s only 3 patterns to learn on any instrument. Diminished is its own thing, man, but it’s in the dominant family. That’s why a lot of people don’t like calling minor7b5 chords “half diminished.”They’re minor family chords, they don’t normally act as dominant. They’re not “diminished” at all, they’re just dark minor chords. Their function is subdominant, not dominant. That’s a lot of nerding there but I’m stuck on a plane, whattyagonnado.

[@lucasfabisiak9586]

My guess regarding why the E7 to C isn't as strong of a cadence as the others is because the third of C (which is E) is what gives the chord its color, so its presence in the previous chord makes it more similar to it than the others (less tension prior to the resolution). That's perhaps also why the dominant third (in this case, E7), especially with a #9, can even be used as a substitution for the I chord in, for example, a I vi ii V progression. So, instead of C Am7 Dm7 G7, you get E7#9 Am7 Dm7 G7, which sounds quite cool.

[@nxyuu]

I also feel like that since it's already so uncommon, my brain just automatically assumes the Bm7-E7b9 is going to end up at Am in some circle of 5ths progression (and im going to assume that most people feel similarly) so since there's already an established "path" for the vii7-IIIb9-... it would be difficult for a new use to become commonplace simply because people will chose more familiar options like backdoor or tritone sub edit: I saw another comment point this out, and mentioned that you can resolve E7 to C6 instead of C so you get that A which makes it a little more satisfying

[@lucasfabisiak9586]

@@nxyuu Sure, but the reason that works is because C6 is an inversion of Am7.

[@sus-kupp]

The same could be said of G7 though.

[@lucasfabisiak9586]

@@sus-kupp How so? G7 is GBDF.

[@mikesmovingimages]

I agree. The lack of a progression to the third of the scale (E) weakens the resolution. The resolutions are to the 1st and 5th notes of the scale, and that by parallel fourths (hidden parallel fifth to boot!), creating a perfect fifth that is meeting the existing third. Try that alone and compare it to the other three options, which do not start with any notes in common with the resolving chord. It "works" but is less interesting, though maybe useful as a deceptive cadence.

Gonna have to watch this a couple more times to grok everything you’re sharing, but I wanted to show my gratitude for the work you put into the presentation. The visuals of the keyboard, the chord names, and the color highlight when the chord is played, really helped me to understand how one chord flows to another. I’ve been trying to step up my songwriting, and this is exactly what I needed to learn, ‘cause I’ve been playing with 2-5 variations, dim7’s, and aug5’s and how they feel as they resolve. My theory is a little weak, so, here’s this video to help me. !!! The tension and release, the sound of one path and resolution, compared with another, gives me cues of how to play with these changes to tell the emotional story inside a song. This lesson is filled with pearls. Thank you., Mr. Keithson.

[@michaelkeithson]

Mitchel! Thank you so much for your generous comment 🙏. I'm really glad to hear that you're getting some value from my videos. Cheers

[@Guitarslngr]

Nice job. As to the Bm7-E7b9-C, and "Why don't we see it," I think it is associated with resolving to Am (which is relative). If you resolve E7b9 to C6 by adding the A, the solutuion is much stronger. My two cents anyway. You are a good teacher. I feel as if we are having a conversation...

[@seanperkinsmusic]

Also, no pull from F to E in E7 to C, which I think has the strongest resolution, after the LT resolution. The E already being in the chord and sustaining into the C chord feels softer than when the F and B pull in contrasting semitone movement.

[@carbonmonoxide5052]

A couple things on the III7 - I resolution: Something very close to this resolution is found in the Kabalevsky Violin Concerto in C Major. In the third movement, there is a chain of these resolutions that marks a large cadence. The actual chords are F/D# C#m/E Am (and it’s later repeated up a minor third). While it is technically just a chromatic mediant resolution, it feels like a dominant and is treated like a dominant, clearly making it a substitution (the E in the bass helps a lot with this). The F/D# chord before it is a Ger6 in Am (and Ger6s are just tritone substitutions of II7 or V/V), but it also acts as the III7 of C#m. Since we have only have three diminished chords, C (Class 1), C# (Class 2), and D (Class 3), we can then analyze everything in relation to them. A dominant built on a note in Class 1 will include or imply the Class 2 diminished chord and resolve to a chord built on a note in Class 3. To connect this to the 2-5 and backdoor 2-5 (and other 2-5 variations), any chord built on a Class 2 will have subdominant function leading to a dominant function chord built on a Class 1 note, which will resolve to a chord built on a Class 3 note. In other words, in any given key, there are actually 8 tonic chords, 8 dominant chords, and 8 subdominant chords, although most music tends to limit focus to only a few of those tonic chords at a time (ex: modal interchange focuses on the relation of C to Cm, using the relative minor focuses on the relation of C to Am, and classical pieces in Cm often end their expositions in Eb).

[@31plemoine]

At 10:20 I really like when you "discover" how E7 resolves to C as a result of the properties of the diminished 7 chord. Neptune has been discovered after noticing some discrepancies in the orbit of another planet and by pointing a telescope at a region predicted by calculus only 😄 To my knowledge, the resolution exhibited by the backdoor dominant can been found by selectively altering the regular dominant, but I like your explanation better. It has some unifying elegance and examplifies once again how the diminished 7 chord can behave as a gateway. At 11:55 I have to disagree though. Modal interchange is a great tool when a single chord is borrowed. It's fruitful and brings transient modal colors very effectively. However, from experience, when two chords or more are borrowed from the same mode, there's a risk that tonal relationships between them will emerge back. As an example, you notice that Fm7 and Bb7 are respectively degrees IV and VII in C aeolian, which is simultaneously true and misleading. The two chords exhibit that predominant/dominant function which implies a strong pull to Eb major as the new tonal center. It's precisely how iiV cells (either major or minor) are used in countless standards. In other words we have plain modulations here, from C to Eb and then back to C. On the contrary, it's a prerequisite of modal interchange that the tonal center stays the same thoughout, only allowing to change its modal color.

[@normanspurgeon5324]

One of the significant problems connected to this chord, is that most people do not play the E natural, over the B flat 7th- the correct note is e natural, of the chord d minor 7th flat five, with an e natural, with B flat in the bass. its's a 4 minor chord- with the e flat used as the melodic tone, and entirely different harmonic scenario results. Example- C maj7, C 7th, F major 7, B flat 7 with #11 is the correct melodic scenario, as in Misty. the B flat note is a melodic tone, not a root-

[@RichardEarle-l5w]

Very thought provoking in it's mechanics of 2 elements moving up, moving down and how it draws the ear to the resolution. I have to rewind and listen a lot but, with the slow repetition the fog starts to clear. Also I really appreciate the way you segue into "tangents" like Modal Interchange here referring back to your previous videoes on those subjects to help build a concrete understanding of how these things are ...homogeneous(?)

[@seanonel]

Disclaimer! I wrote this comment before you started talking about it on the video! Still, my fingers hurt from typing it, so I’m not deleting all that hard work! If you build a diminished off of the 2nd, 4th, flat 6 or 7th degrees of a scale, you can lower *_any_* of the notes by a half step and all of them will resolve to the tonic. If we play an F diminished whilst in the key of C we can lower the F to E to give us a “median dominant” that ideally resolves to the relative minor root, but also does a good job of taking us to the tonic. Lowering the Ab by half a tone takes us to the diatonic dominant. Similarly, lowering the B to Bb takes us to the backdoor dominant and lowering the D to Db gives us the tritone substitution. Similarly going up from that diminished by a perfect fifth to (for example) C Diminished allows us to do the same thing with some really nice altered dominants all resolving to the tonic of C. Probably nothing new to you, but just stuff I discovered while I was mucking around... Very interesting, thanks mate.

great video. to your aside question, i can't think of an example of that "side door" cadence either, though now i'll be on the lookout. my guess about its rarity is that it strongly suggests a move to the relative minor... in C, Bm7-E7 is the ii-V to Am. that relative minor has its own host of associations and complications, and the two common tones from the triads Am and CMaj weaken the surprise element. that said, i don't recall ever thinking about this, so yay.

[@michaelkeithson]

Hey, thanks for the comment. I appreciate your take on it. 👍 I agree, I think there is already a stronger diatonic resolution to the Am so the movement to the C feels weak. Also, as lots of people have mentioned, we already have the 3rd of C in the E7 and so the lack of movement to the onto the 3rd weakens the impact of the resolution. Thanks for sharing man. 👍

8:25 - 10:57 … lol, stopped after the last section to work out that fourth dominant chord, myself. And the obvious answer without thinking too much about it is that the position of that ‘weak’ D that dissolves away, is costing us more as a ‘dissolving 7’ … ? Perhaps a ‘dissolving 5’ is the least of our problems, but a ‘dissolving 7’ is the most problematic (with the other 2 options being somewhere in-between?)? Very interesting … Food for thought …

Brilliant thanks 🙏

[@damiens4601]

We need a website or app where you can write chord progression and then add and tweak with all those options to test things out

[@insight827]

Wow, this is high quality

[@michaelkeithson]

🙏 Thank you. Pleased you enjoyed it. 👍🎹

[@GreggOliverBass]

as far as the "little aside" goes... I think the E7 to C sounds weaker than the others is because the E is the Tonic in the sub and the third in the C... without any half step movement in the 3rd of the C, it weakens it a lot

[@michaelkeithson]

Thanks Gregg! Yeah, I think you're right, also because the E7 is already the dominant chord with a diatonic resolution (Am) it has a stronger pull to the A than the C so it's not as pleasing.

Good bless you Michael

[@wpaganperez]

Thanks!

[@jeroenbohan3645]

About the E7-C: you’re right, this one is not being used at all. The other cadences (G7-C, Db7-C and Bb7-C) all have the important line F-E. This is not the case for the E7-C cadens. The E is the major 3rd of the C chord, arguably the most important chord tone. The E7 already contains the E, giving it away too soon. Also, think about III in C major: Em7. Why is this never used as a replacement for V, although it’s third related to it? Because it’s also third related to the tonic. It just sounds too much as a tonic. The same goes for the E7, although in a lesser degree.

[@sus-kupp]

Your point about the F-E line being most important is very interesting because it seems intuitive that the most important would be B-C since it resolves to the root. But in jazz you will often see the V7 replaced with a V7sus, replacing B with C. If B-C was most important, using a V7sus wouldn't make any sense because you are replacing the most tense note with the most resolved note, which would surely dissolve all tension. It doesn't however, because the most important line is not B-C but F-E. Additionally, in jazz you typically will resolve to Cmaj7, which contains a B, and occasionally even a Cmaj7#5, which contains a G#/Ab, but I can't think of any common resolutions that include an F.

Another excellent lesson Michel! Thank you!

[@michaelkeithson]

🙏 Thanks Paul! I appreciate your kind comment, thanks for watching.

[@batlin]

Thanks! I saw some nice examples of Stevie Wonder's backdoor progressions before but this helped a lot to understand better what's going on and why it works.

[@michaelkeithson]

Yeah, Stevie loves a backdoor progression 👍 Glad you found the video helpful.

[@onpatrolforthejuice]

The way I remember the sound of the backdoor 2 5 is the victory song in final fantasy

[@wilyamdein1359]

As always thanks sir

[@michaelkeithson]

🙏 You are very welcome!

[@LZMAmzelle]

Maybe the Bm7 - E7b9 - C resolution should be called a relative 2 5 1 or relative dominant as it resolves to Am7 which is the relative of C major. Or perhaps it makes sense to call these by their modal function, this one being an Aeolian 2 5. Anyway, they all sound cool and I’m gonna put them all to work! Thanks for a brilliant video!

[@michaelkeithson]

Cheers for the comment man, I appreciate the input 👍
