The Chord That Should Not Be - 7#9 aka "Jimi Hendrix Chord" [MUSIC THEORY - MIXED THIRDS]

[@SignalsMusicStudio]

CLARIFICATIONS AND CORRECTIONS! 🔴When playing a 7(#9) chord, it's common to remove the 5th in the chord. Why? Because it really doesn't add any "important flavors" to the chord. Also, the nature of the guitar makes it difficult or sometimes impossible to play afull 7(#9) chord. 🔴As mentioned at 07:10, you'll rarely hear the 3 and b3 played side-by-side on a single instrument. But across different instruments, you can expect that the two will compete against one another in a blues or rock setting. For example, a blues pianist might play A7 with a major 3rd of C#, and in that same octave, a lead player might play a C natural. 🔴There is some VERY UGLY NOTATION at 10:53, during the David Gilmour lick. I wrote this tablature in MuseScore and forgot to check all the staff notes :( 🔴At the end of this video, when I say my videos have "no ads," I meant promotions or in-video advertisement. I don't have ads in my lessons because 1) i hate ads and 2) they completely destroy the flow of an educational lesson. But I do monetize this channel, meaning you probably see some ads before clicking on one of my videos. This collects enough money to pay a few bills, but it's really my patreon supporters who enable me to make straightforward lessons without spamming you with VPN ads, razors, or one of the other hundred other companies bugging me to do ad-reads!

[@Trey-bien]

Good clarifications. Thanks much!

[@Trey-bien]

Thanks for commenting about omitting the 5th! I was noticing that when I go to try this chord on my baritone uke I'll have to omitting the 5th scale degree for lack of strings. So it's good to know that's a common practice on a six-string.

[@Williamk492]

The 5th is often left out, especially with jazz chords (dominant 7, minor 7, mayor 7 etc.) These are called ‘shell chords’. Playing the 5th in the chord just ‘clutters’ things up.

[@TomBelknapRoc]

This was an amazing video! It's so necessary for us as musicians to come at topics like this major/minor rub from new perspectives and with a different focus. Yes, I can see why this video could be confusing to a newer musician. But the good news is: it's all confusing until it's not. Food for thought is way more important than knowing every ingredient.

[@MrBileTooth]

One of the best lessons I've seen on KZbin, I'd rate it 7#9/5.

[@boi5275]

[@damiens4601]

Another awesome thing you can do is V7#9 - V7b9 - i . Or, speaking of stealing from Pink Floyd, D7#9 - D7b9 - Em

[@SignalsMusicStudio]

Yep! I didn't want to get into flat 9s (that's it's own lesson IMO) but i teach V7#9 - V7b9 - i in the Codex. The pink Floyd song Breathe actually resolves more like a backdoor cadence though, bVII - i (D to Em)

As a new viewer, that face reveal of talking while playing was something else haha. I was thinking "Oh that's cool, he must've pre-recorded the script and then played to it to keep the notes in line with what he's describing." But no, you were playing and casually reciting your script at the same time like a savage! Love it!

[@themanumission]

You're a great, great teacher and this video is gold. Great didactics without under or overestimating the audience. On point! Thanks!

[@SignalsMusicStudio]

thanks for this nice comment 😁

[@GarageGroovin]

The solo section around 10 minutes in is great! That weird modal mixture sound where just one note shifts a half step has become one of my favorite musical "toys" - that little shift really stands out to the ear and creates these little moments of interest. I think I actually first started exploring this as a result of your video where you demo'ed that Emaj7 - Am progression, but another great example is the jam sections from The Grateful Dead's song Eyes of the World. It goes from an Emaj7 to a Bm, and there's this shift from E major to E mixolydian. In that case the note that "shifts" is the 7th - you play the natural seven over the Emaj, then use the flat 7 in the mixolydian portion. Every time I land that little shift as the chord changes, there's a special little moment of interest and satisfaction. There are so many cool progressions that use a trick like that, it's a very cool thing to explore. Thanks for your vids!

[@5400bowen]

It’s been used over and over all over rock and blues for at least 100 years.

[@mikedonovan4768]

Finally ! I used this 7#9 Hendrix chord in one of my recordings and didn't know what it was, but it suited the track. Now I know ! Thank Jake 👍

[@daviddavidson1355]

Nice to see you again Jake, your videos are so insightful

[@salmonflop]

One thing to note is that minor 9th intervals sound very dissonant and won't sound right in most contexts. A 3 above a b3 creates a minor 9th interval, while a #9 above a 3 creates a major 7th interval. This would explain why it sounds better in major. However, that doesn't explain why the #9 sounds good in the bass (this creates a minor 9th). It probably works because it gives the major chord a dominant sound, which is all about tension.

[@rome8180]

I made exactly this same comment. The minor 9th has pretty limited application. It sounds really cool if you add it to a V7 chord before resolving to a I or a i, for example. The reason is because the V7-I movement is already built on tension and release. The V7 already has several notes pulling you toward the tonic chord. By introducing a b9, you simply get an even greater pull toward that tonic. The major 7th is much easier to work with.

[@escueladeartesemocionales]

I ALWAYS wonder about this. Love the hendrix chord since the first time I heard it. This was top notch as usual, you spoiled us! Thank you

[@crawdaddyOKC]

The Chord Progression Codex is amazing. Thank you for putting that together.

[@fazzification]

Welcome back jake. Have learned much from you and look forward to learning a lot more.

[@UrbanGarden-rf5op]

Interesting. I wrote a YT comment about this a couple of weeks ago. In Sweden we call that a -10 (minus 10) chord. As you said it contains both the major and the minor third. So there is a 3 and a flatted 10 (the minor third, one octave higher). That way of thinking makes the function of the chord clearer, at least to me. Like @ulomagyar7166 says in the comment I guess it should be called a minor 10. The problem arises when you have a minor chord with a major 10. I guess it could be minor 7 add maj 10. A bit of a mouth full, I think I’ll stick to +10. A long time fan of your channel. I’ve bought a couple of your well crafted courses. I recommended your excellent Codex to a music student friend of mine. He couldn’t be happier. Neither could I. Keep up the good work𝄢

[@SignalsMusicStudio]

Good to know, that might be a regional thing! I've never heard of a minor 10th in this context, but everything you're saying makes sense to me... however the + sign is used to "augment the 5th" so a +10 chord would be very confusing for many musicians I think. Also I'm thrilled you're enjoying the book :)

[@UrbanGarden-rf5op]

Sorry my bad. Yes of course, that would be an aug 10. So it only works in Sweden🇸🇪

[@thelanavishnuorchestra]

Hey, that was really useful and presented clearly. Instant subscribe. I'm gonna hit up your back catalog.

[@Henry-fv3bc]

Important detail is that the minor third is often played sharp (with a bend) where possible (e.g., in lead).

[@williamhiles7404]

Paging Mr. Page. 😊 LedHed Pb 207.20 🎶 🎸 🎹

[@mbmillermo]

Steve Winwood played it on the keyboard in "I'm a Man" with Spencer Davis Group. The Paramounts (with Robin Trower) had a UK hit in 1964 with a cover of "Poison Ivy" that included the E7♯9 at about 1:16. It also had a lot of G and A, so there is a chordal similarity with "Purple Haze". Hendrix also used it in "Foxy Lady" which was recorded before "I'm a Man" even though it came out later. I guess it was a popular chord at the time because Paul McCartney was pretty excited about using it in "Michelle" in 1965 (where he sings "ma belle" is B♭7♯9).

[@80sMeavyHetal]

Love that chord, it's like a joker in music theory; breaks all rules but it works!

[@SignalsMusicStudio]

I still don't understand why it works 😅

[@80sMeavyHetal]

@@SignalsMusicStudio Me neither ;D But that's, apparently, the magic of music

[@Veepee92]

​@@SignalsMusicStudioThe simplest explanation why the Hendrix chord works is to not treat the C as a normal minor third (6/5). 12-tone equal temperament makes a comma the size of 36/35 vanish, meaning that the 6/5 minor third is equal to the septimal minor third, or 7/6. It also makes the harmonic seventh 7/4 equal to 9/5. This means that a no-5 Hendrix chord has pitches 1/1, 5/4, 7/4 and 7/3 (=7/6 one octave above the root) instead of 1/1, 5/4, 9/5 and 12/5. Thus the chord will be tuned as 12:15:21:28 instead of the much more dissonant 20:25:36:48. The former has smaller values meaning that it will have less harmonic entropy than the latter. The C can also be interpreted as 19/16 (!!!), in which case the chord is 1/1, 5/4, 7/4 and 19/8 and tuned to 8:10:14:19, demonstrating even lower harmonic entroy. In 12-tone equal temperament it is still identical to 12:15:21:28, anyway.

[@fromchomleystreet]

One of the most intriguing applications of this “wrong but right” clashing thirds thing, is in the song “Drive my car” by the Beatles, specifically in the “you can do something in between” bit. The twist is that the perceived dissonance isn’t between major and minor thirds that are actually played, but between the minor third that we ACTUALLY hear, and a major third that, while in reality it is entirely absent, is so clearly IMPLIED by the context in which the chord appears that our brains sort of supply the major/minor dissonance that isn’t really there. The weird thing is that, in the context of the song, it sounds really crunchy and dissonant, and is often erroneously transcribed as an A7 #5 #9 chord, a pretty dissonant chord. But if you actually analyse what notes are being played/sung, in isolation, it’s not particularly dissonant at all. It’s just a major triad in first inversion, with an added major 2nd above the root. Specifically, it’s just an F add 9 with the third in the bass. Now, if you just play an F add 9 over an A bass, in isolation, it is NOT going to sound like that chord from “Drive my Car”. Out of context, it entirely lacks the distinctive dissonant “crunch” associated with that moment in the song. But… in the song it appears in the context of the key of D major, exactly at the point where we expect to hear a classic dominant 7 chord built on the fifth degree, which would be an A7. Also, the lowest note is an A. So the context primes us to experience the chord, not as an F chord, but as some kind of A7, even though it’s missing the major third required to make it that chord. If it’s any kind of A chord, you would think it would be an A minor, as it DOES have the minor third. But we simply don’t experience it that way. We experience it as a major chord, and we experience the minor third that in reality is an integral part of the chord as a dissonant blue note over it.

A couple of years ago I was improvising a song on piano, and I happened to do that minor third over a major chord, and it's so good. My tune feels completely wrong if it's not there. I just checked, and I do not play the fifth, but a minor seventh. I might change that to a major seventh in a later verse, but it's actually almost too spicy in the context of the tune.

[@manojkrishna8839]

I know some Indians songs that have both major and minor thirds. They were composed in Sindhu Bhairavi and Piloo / Kapi ragas. One of them is "Thumbi Vaa" composed by Illayaraja. It was composed in the Kapi raga. 😊

[@SignalsMusicStudio]

Yes! Raga Jog also employs both thirds in a pleasant way

[@chrishelbling3879]

Wonderful topic. I remember a G7#9 used for the piano fill stabs, in between the phrases in the chorus of "Maybe I'm Amazed," for the reasons you mention. I think this chord was favored by jazz keyboardists, since they can't play "in-between" the keys to hit that blue note, the way a guitar / voice / clarinet / harmonica can bend in to it.

A maior dificuldade que eu tive no estudo da harmonia foi esse "olha como soa estranho as terças maior e menor tocadas ao mesmo tempo", aí eu ouço o som e acho lindo. Foi um caminho longo e árduo pra entender a harmonia tradicional e como ignorar ela solenemente na hora de compôr, pra não limitar a arte a uma convenção, uma vez que a convenção jamais se aplica a expressão de maneira eficaz.

[@artysanmobile]

I love that dom7-#9 chord. It has to be played in the right inversion and with the right dynamics, and then the paradox just flies right by, with the dominant 7th below the #9. It is a chord that must come with its own attitude. Leave that behind and it will fail.

[@dmytrotsvyntarnyi799]

3:33 yes, and no. The chord that uses both the minor and the major thirds both of which function like thirds and not ninths is often cslled the "split-third chord" or "mixed third chord"

[@gerardobecher9404]

Tie Your Mother Down by Queen is another example of playing the minor 3th followed by the major 3th. It's in the very well known rythmic guitar riff created by Brian May that plays a natural C followed by a C# on an A chord. There's also a C chord later, where the minor third appears and the major third goes out.

[@cyrilleharvey3771]

E7#9 is also the first chord in Sunny Day Real Estate's song "Killed By An Angel". First time I ever played that chord was when I figured out that song when I was 14 or 15 years old. I'm almost positive (despite my fuzzy memory of how to even play the song) that the guitar line in the verse resolves into dancing with accidentals around an arpeggiated A Maj chord. Interesting in light of what you were saying about the interplay of E7#9 and A Maj It was fun to hear your analysis of this. I had always felt like this chord shape was dissonant and a bit strange, yet powerful as hell when utilized properly; and I hadn't really thought about it much in the last 25 years since then.

You said it well: the clashing of thirds. Which is why I really prefer calling this a "flat 10" chord rather than a "sharp 9." But I realize nobody does that.

The tritone (3-b7) is so dissonant that it can easily support b9, #9, b5, #5, #11, 13, b13 … it can handle anything!

[@DavidLloyd-x1x]

It's (shhh) jazz. A tritone substituted Bb13 shell chord. The key elements are the D (maj3) and Ab (7) of the Bb13 that invert to produce a G# (maj 3) and D (7) in E7#9... G moves from the 13 to the #9 (F##). You can do this with all altered and extended dominant chords due to the tritone between the maj3 and the 7. Blues loves a dominant seventh chord so we're not compelled to resolve it, and because the bass is firmly E, we think E dominant. This is the same reason that E minor pentatonic works over an E7 chord... that "G" is actually an F##, #9. It works fine over a bass player playing a walking line that incorporates G# (maj 3).

[@stubbsmusic543]

This relationship naturally occurs in the dominant 13th Court. From the bottom up, the voicing of the flat seventh third and 13th creates that critical element. E7#9 A13 D7#9 G13 highlights the usability and beauty of that musical phenomenon. The song "Spinning Wheel " uses a very obvious version of that combination in a sequence. On a more obscure note, the sonority created from flat seven major third and sharp nine in atonal classical music is referred to as the "Viennese triad."

[@Pooter-it4yg]

In jazz (and therefore funk and fusion) the full scale elaboration of a 7#9 chord is typically either of: R b9 #9 3 #11 5 6 b7 (half-whole diminished scale) R b9 #9 3 #11 #5 b7 (altered scale) Both sound bluesy but the latter especially so. Actually by shorthand convention the first one is notated 7b9 and the latter 7#9, even though both contain both 9ths as well as other alterations.

[@jmonty2005]

Nice. To me, the true essence of blues music is the major blues scale, which has both the major and minor thirds

[@willbohland3698]

That's crazy. I'll be damned. That really does have a very distinct "chordish" sound of it's own. The intervals combine to create more than the sum of their parts. That's what chord is to me, "chordish."

[@obiwanjacobi]

Years ago, I let a band mate listen to a solo of mine where I used a minor 3rd on major chord. He thought it was out of tune. So there are people that don't like that sound (or my solo was rubbish). Thank you, Patreon supporters!
