I have a bit of a headache at the moment, but when I can give this more attention, I need to figure out why he calls his version E-dorian.
I know about modes but I don't really consider them much...in my opinion, modes are best for describing 'key' changes on 'just intonation' instruments, but, if one uses the typical 'equal temperament' tuning of modern times, then there's no need to refer to a mode UNLESS you really are showcasing a mode. Of course, I don't play jazz, so....
I guess a jazz player might use them more.
_Initially_ I thought it was in E dorian because it contains all the tones of the D major scale, but the home note was E. (And yes, E dorian is a type of E minor, but "dorian" is a more specific term than "minor").
Then, after examining the tune more closely, I realized that it doesn't contain any C sharps. So I can see where some would view it as E Aeolian, which you were calling "E minor."
BUT: There aren't any C naturals either!
Really this tune is neither clearly dorian nor aeolian, since it lacks any 6th that would give it a dorian or aeolian quality. Does anyone know the technical term for this kind of mode/scale? I've heard it called "gapped" or "hexatonic" (or "hexatonic minor") but I don't think these are necessarily the best terms to describe this type of tune. (Some people just call this "modal," but I find that unsatisfying and silly, since _all_ tunes are modal! But for some people, "modal" seems to be a sufficient label for anything like E dorian, A mix, etc.)
I can understand where this wouldn't SEEM to make any difference to someone playing a C/G concertina, but it does make a difference to someone who plays melodeon in D, for instance, and it actually would make a difference on the concertina if you were playing accompaniment. When I'm searching for a tune and using "The Session" or "Tune database" etc., I know it's a tune where I "have all the notes" when it's listed as "E dorian," whereas if they had listed it as "E aeolian," I would be missing the C natural. So as far as I'm concerned, my purposes (selfish melodeon player!) are well-served when it's listed as E dorian rather than E aeolian or E minor, although I recognize that none of these designations suits this tune 100%.
If you look at the Breathnach collections, you'll see a lot of tunes like this transcribed with one sharp. This certainly has its logic, since it would be silly to transcribe them with 2 sharps when there is no C sharp to begin with! So in that sense, perhaps the database should list the tune as E aeolian. My (selfish) preference for listing it as E dorian is related to my being "D-instrument-centered" (de-centered?), which makes C natural seem like an accidental to me! (as it would, perhaps, for pipers or keyless flute players, where C# is part of the natural scale on their instruments, whereas C natural is produced by covering a hole halfway or hitting a key.) My guess is that whoever listed that tune on "The Session" as "E dorian" is playing an instrument where the simple scale includes 2 sharps.
I also don't think that the modes are useless for equal-tempered instruments, as you indicate. My D box is equal-tempered, yet there is a definitely difference between E dorian and B aeolian ("B minor"). (I think what you said about just-tuned instruments and modes DOES apply if you were dealing with a chromatic just-tuned instruments, on which there would be a difference between D dorian and E dorian, but that's a different topic...) For SOME players, it does make a difference, and no, it's not jazz-speak, the discussion of modes applies quite nicely to traditional music, at least for those who -- in addition to "just playing tunes"-- also happen to like to communicate about similarities and differences between tunes. I imagine that these modal descriptions/differences are also important to people who play accompaniment instruments, which you may or may not consider to be traditional.
Sorry if I botched anything up here via typos or my "gapped understanding." I'm not a music theory expert but I do insist that there is something "practical" about those seemingly esoteric modal designations...
