Yes.[1] In particular your point about analyzing chords in isolation is spot on.

> All notation is analysis
So whenever you write something down in music you are (of course) making some simplifications and you are also doing it for a particular purpose. Usually the purpose is performance. So when you write something you are providing an instruction to the performer.
So when you write Cma7 for a jazzer, that’s an instruction that you are generally in the major tonal area and they may well play a Cma9 or a Cma7#11 for example. This is why my functional harmony teacher used to get annoyed by people writing the “Crosstown Traffic”/“Purple Haze” Hendrix chord as E7#9 (which you see a lot). He would say it is E7b10 because that g natural is coming from the minor modes so it’s actually the fourth degree which has been flattened. If you call it a #9 you’re telling players the wrong scale for improvisation (pretty much everyone else in the whole world calls it E7#9 though).
Likewise going back to your point about slash chords, a lot of people learning this stuff get hung up on “what is this slash chord really?” (Eg if I’ve got B/C or whatever what actually is that) whereas when I’ve talked to really serious musicians in that world who play that kind of intense modal music they really are thinking about what the slash chords are in terms of where they come from and what they are leading to. Because that gives a sense for what the underlying tonality is. You can’t get it just from the notes of the chord vertically in that one instant.
If you look at baroque music and earlier, if you just do a vertical chord analysis (eg something like Gesualdo if you really want an extreme example) the chords make absolutely no sense in many cases but that’s because they work in terms of voice leading (ie context) rather than vertical relationships. Analysts used to call that feature “vertical false relations” because they found the vertical chord analysis troubling.

you mean the third degree I think?
at first I thought your teacher seems overly pedantic here, but it does kinda make sense... I'm surprised I've never heard anyone argue that before!
I'm not sure your teacher is right. The notation should be Em7b11.
Ultimately, I think it would depend on whether Hendrix included F or F# in the scales that he used to solo over The Hendrix Chord. If he includes F, E7#9 would be the better notation, since it suggests an altered mode: I, IIdim, IIImi, IVdim(and probably Vdim). (E, F, G, Ab, Bb, C D) . If he includes F#, then you could make a case for E7b10, which I would read as implying a blues scale, although I've never ever seen that notation: I, II, IIImi, IIImaj, IV, V (E, F#, G, G# A B C D). My bet is that Hendrix plays F, not F#, given that he was a jazz musician before he was a rock musician.
The argument for Em7b11 would be that the major third is actually the FOURTH note of an altered scale. . Better still: Em7b9b11. Or I suppose you could be uncontroversial and just write Ealt.
Chords derived from altered scales, and chords based on quartal stacks are both severely broken cases in modern chord notation. Neither seems to have settled chord notations, and the chord notations that do exists vary greatly by dialect.
(Jazz guitarist who very much prefers modern functional chord notation, that implies both scale and chord, to the older Broadway jazz notation style).
Well he would say it's not functioning as a minor chord it's functioning as a dominant, so any kind of Em is off the table. Also if you call the major third the b11 you are turning one of the notes of the main triad into an extension which he would take issue with too.
But you know, obviously do whatever makes sense to you. As Schonberg says in Harmonielehre, "There are no rules of music, only rules of style".
Also as a sibling to your comment points out it's a blend of major and minor, so also in jazz you'll often see something like E7b9#9b13 written, but that really makes no sense in terms of a scale. The 9th is either flattened or sharpened, can't be both. So the next degree of the scale is the b10, which also makes sense when you think about something like a "diminished" scale which people play over this chord often.
He also used not to like the name diminished for the scale btw, but would refer to it as one of Messiaen's modes of limited transposition. I can't remember Messiaen's nomenclature exactly but the scales which people call the wholetone/semitone diminished and semitone/wholetone diminished are one of his symmetrical system of scales. IIRC there are 3 distinct "diminished" scales and all the other ones are just modes of these three. So you can see that the st/wt diminished starting on D is just a mode of the wt/st diminished starting on C for example.[1]
> Because that gives a sense for what the underlying tonality is. You can’t get it just from the notes of the chord vertically in that one instant.
I'm not at all into music theory and such, but your passage just reminded me of what AlphaPhoenix mentioned in his latest video[1], where he analyzed two frames from an experiment, both with a piece of string stretched horizontally across the screen.
They look identical, but they are not. One is a stationary string and the other in an oscillating string which just happens to be flat at that moment in time, but the pieces of the string still carry momentum.
> He would say it is E7b10 because that g natural is coming from the minor modes so it’s actually the fourth degree which has been flattened.
I'm guessing you mean Emin7b10.
It's in interesting take, but a bit weird considering you wouldn't stack the chord that way. You want to voice the G# below the G, E G# D G, making a major 7 interval which sounds good. If you instead voice it E G D G#, then the G to G# will form a minor 9th which is pretty clashy, generally avoided, and doesn't sound like the Hendrix chord anymore. Try it out, tab (0 7 6 7 8 x) vs (0 7 5 7 9 x). This is a standard jazz voicing rule of thumb, although I forget the name of it.
All of this makes a lot of sense. But to add; a semi-professional piano player I know once gave me a heuristic that can help sometimes, namely “the lowest fifth contributes the most to what the chord feels like”. But you can still get into discussions about whether something is, say, a Dm/F or F6 (and I see a lot of tabs where I disagree which the author's choice).
(semi-professional piano player here) That's interesting. I've never heard that...not even sure what "lowest fifth" would mean. I would think that the root and the third contribute the most, right? The fifth is sometimes even omitted. I'm very curious how this might work. Do you have any examples?
(Semi pro jazz guitarist here). The heuristic I was taught: the accompanist owns the 3rd and the 7th, which allows the SOLOIST to choose #4, 5th or the #5 as the muse dictates in the moment. The 5th is an semi-avoid note, until I hear the soloist commit to a choice of 5th.
I guess it means in the sound scape as a whole, potentially including multiple instruments. But to keep it to a single piano, e.g. if you play B3 D4 G4, then it won't sound like a B chord (neither minor nor major) because there's no fifth. Instead, you'll hear D5 as an overtone of D4, and G4-D5 will be the lowest fifth that you hear, so it is readily interpreted as G/B. If the third were the most important, then this would have been a Bm, which is pretty clearly isn't unless you add an F# (or there is some other instrument in the mix that provides one).
Allowing that I'm simply not sophisticated enough to understand this, I think he's overthinking things. :-)
I mean, B3 D4 G4 in isolation probably does sound like G/B to western ears, and maybe the overtone explanation is acoustically relevant, but it seems like there are not too many other things that those notes could be, and the spelling clearly spells a Gmaj triad.
