Thank you, again, for going really deep. I'm doing this every day (transcribing, arranging, composing, playing, sequencing, teaching, the whole shebang - which is a 'must' for musicians today) but it's always fantastic having complete information to fill-in the gaps (IMHO even the best don't know everything) - never enough. I feel like I'm always "midway" regarding my humble skills. There seems to be no such thing as complete knowledge about music, but that doesn't keep us from learning every day.

I have learned a lot when it comes to modernism and I thank you. Mostly in the area of modes that are not normally used in most tonal music. I was really looking to break free of my many years of using traditional harmonic functions, which had suddenly just started to seem like "not enough" to my ears anymore. So thanks! BTW this is the wrong topic to ask this on as I am not even thinking of slash chords, but I think one gets more replies while replying to the latest video. In the section of modes, I don't think you have the Harmonic Major in there anywhere and its modes. I was just transcribing March of The Slave Children From John Williams(as an exercise to get out of my traditional tonal ways, finding music that does not fit into older harmony methods) and realized that it fit none of the modes described so far. So I literally googled (major scale flat six) as I was guessing that it had been built on some mode from that and I found it is called the Harmonic Major, which I honestly did not know existed(most of my music experience is from about Wagner backwards so I love your page). The piece starts with the 4th mode of that basis and the reference chart calls it Mixolydian flat 9. Anyway maybe you can also cover this in your theory sections:) Thanks again for your page. Been following almost since you started explaining interesting modes and concepts!

For E/F (the first one) you put on the board the first inversion of E over the F. You put F G# B E (F + 1st inversion of E). For all the other chords, you just put the note and then the E major triad. For example, for E/D you put D E G# B (D + E major triad). For E/C, you put C E G# B (C + E major triad). Etc. Only for E/F did you put an inversion rather than the major triad itself. Why?

Hi Rick. Excellent video and thank you for showing. I'm not really a jazz guy, so I'm likely missing something here. My question is: to use the F# mixolydian over your 2nd example (E/F#), wouldn't that have to assume that the E triad is from lydian, in the key of B ? In other words, we need to assume a key, within this context, but the key is not shown. There is nothing in the chord name "E" that tells us it lies within the framework of the key of B major (the key that would make E function as lydian (if we spell its full scale E lydian). I say this because your example includes an A# (in order to give the F# a major third in order to define it as Mixolydian. In no way does the E triad designated on the top of the slash indicate that this E triad in question is necessarily formed from E lydian. So, from this, could it be concluded that using the F# Mixolydian scale, in this example, would only work if the overall key this slash chord is appearing in would be B? Could we therefore assume that if this slash chord appeared in the key of A, we would use an F# natural minor, in order to account for the fact that, in the key of A, The third of the F# would be A natural? Thanks.

Rick, a few thoughts to pass on that might be of interest with your background as a *music* *educator.* Have you heard of *Teachur?* They had a successful Kickstarter where they are trying to disrupt the "normal" U.S. college education process with it's spiraling prices, and develop an alternative. (search for "kickstarter Josh Stanley") In essence, their goal is to use their knowledge of how "college works", leverage emerging technology (blockchain), and facilitate focused use of the preponderance of educational materials available on the internet to map out (stating the obvious): college degrees require -> requisite courses which require -> defined learning objectives -> sources to learn and master these objectives which can then be demonstrated as sufficiently mastered by students to qualify each course towards a degree by using technology (blockchain) based testing, or simply think of proctored tests, but with the addition of a digital record of how well each concept was grasped (think of it as creating a digital record of every answer given on every test towards a degree and being able to review individual answers as a potential employer to see that a candidate truly understood a particular study area, as opposed to simply "graduated with XX GPA"). You could as well oversimplify the effort as constructing some new form of virtual "Wikipedia", where the contents are arranged to map out in detail a progression of internet available knowledge that completely fulfills a degree plan. Their goal is to offer fully accredited degrees in a number of subjects, starting with Philosophy. Just wanted to pass this on, because I believe they, or *someone* can and should be successful in making this happen, and that means in the future, that somebody is going to assemble this hierarchy for degrees in the music field. It's clear to me that you, and dozens of others on youtube together are approaching the critical mass of having entire college level music courses available online, albeit in splintered and scattered form. So I wanted to make you aware in case there is a possible interest in your part of reaching out to them (I'm not affiliated in any way) to possibly discuss *the* *future* *of* *music* *education,* as their model may be able to take it in the future. I'm hopeful that someone like Teachur can come along and accomplish a few things: 1. Road Map out all this knowledge to a progression that can result in a college degree for those interested (assemble all the splinters into something greater, focused, and purposeful) 2. Guide interested learners to Best or Better sources of information on subjects of interest as a side benefit (think of someone like you grading youtube music theory videos for quality of learning with 1-5 star ratings for example) 3. Drive the quality somewhat as the marketplace focuses on this new goal for content authors, and have knowledge gaps filled by new content creation in order to deliver on all learning objectives without exception If Teachur is to succeed and one day bring their benefits to the musical field, they will need guiding lights to help point them in the right direction... perhaps you or someone you know would be interested in getting involved. Thanks for listening and for your great videos.

And it is definitely not B b7 b9 b5 like someone can misunderstand because you repeated it twice, but Bb b7 b9 b5 but in the case of the E major slash chord, it is more like E major b13/ b5 without 7,9 and 11, or we call it Fb/Bb instead and we ignore the enharmonic difficulty. ;)

I realize this is an old video on slash chords. Don't know if I will get response, but here goes. I have been trying to learn "The Goodbye Look" from Donald Fagen. In the first verse (a line of women all in white) there is an A/F followed by an F6. When I played the slash chord I realized I had heard this particular 2-chord thing in other songs, mostly Brazilian. Elise Regina's "Vivir Aprendendo Jogar" comes to mind. Can you tell me about this? Does the progression have a name? I can feel a sense of tension and resolution in the sequence. Looked at the video a few times and realized what you were doing. A/F is analogous to E/C. So the sequence becomes Fmaj7#5 moving to F6. Bidirectional resolution? #5 up to 6 and maj7 down to 6. Compare with Fmaj7 to F6. Think I learned something today! Thanks, Alan Mayne

Why isn't there a better way to speak 'music'? There are only 12 notes in western scale but the language we have to talk about mixing these simple 12 tones is SOOOO inelegant. You hear the chord and it's ahhh I can understand that. ... but listen and look at those charts? ... it's a convoluted gobbledegook. Sure it makes sense but apparently , so does Klingon. Why are we still using this medieval language to describe music, when our spoken languages have become so much more fluid? It is a nonsense. We should just use numbers with decimals, that would give us octaves and accuracy, it would allow for more invention and creativity without becoming confusing so quickly.... Oh and would save a lot of hot wind.

But why though? Why add this extra step? Why not just say “hey can you play an A 9 7 no 3rd instead of that A 9 7 flat.” To say it using the slash chord method I’d have to sit down and figure it out. Maybe tell the band to go take a smoke break while I get out the chalk board. I’m not sure Im a fan of the slash chord. I think western music notation / theory can over complicated things. There’s literally only 12 notes in the whole universe. Learn what all 12 do and you’re fine; learn all 25 (roughly) chords, all 10 or so useful modes. And it’s easier to think in numbers, not letters. If you know how chords are made, you can play anything in any key. That said, as an advanced player I find this interesting (and can’t believe I went 25 years of composing music not knowing about this), but it may turn off beginners. If you’re a beginner, maybe come back to this down the road.
