If someone says, we're jamming in Dmaj, then maybe I'm playing D Ionian etc etc, or maybe I'm playing G melodic minor, or E major, or G major. I decide which seven I'm going to use, then I use them, or maybe I change them. If you are staying withing a key during a piece, then there are only seven. In my mind, in a Western music system, there are only 12 notes. Interpretation - I find things challenging when people refer to modes. This is what I see in most music software, and I feel like the reason is what we were getting into above, which leads to the second thing: (also, perhaps of note, the Aeolian was the original defacto scale, hence why notes start on A) So, software engineers raised there also tend towards an "Ionian is the scale" approach, though some will add Aeolian too, to give you that Major/Minor approach. I was raised in a culture that used songs primarily in Ionian and Mixolydian modes. (Solfege is an interesting system, and could be mapped to any mode)Īs you indicate, it has been culturally proscribed to accept the Ionian mode aka Major Scale, as the defacto standard. Most people I know are aware of "Do Re Mi", and that's the extent of their musical knowledge, they may be aware of keys, major, minor etc, but they don't know what they mean. The next part is what do you present to people. The point being, we could analyze an audio signal and derive potentially meaningful data from it. You have picked up my background, but I think I should clarify a couple of things, I was thinking more along the lines of an app in some ways:Īssuming we are tuning to 440Hz, and attempting to analyze an audio input, if we receive: 18Hz, 20Hz, 21Hz, 24Hz (super watered down example) then the app could conclude that the song is in D Ionian (and perhaps display every mode as an option). D Maj is a mode in of itself (Ionian), why is it in any way an overcategory to mixolydian? Though I have to say I do have a background with non-western music as well as classical training.Įdit: You say A mixolydian is a mode of D major. Your decades of studying are wonderful, and I'm sure you're right technically, but if I were jamming anyone and they told me the piece was in Dmaj, I would look to play Dmaj, not A mixolydian. Mixolydian A is a rearrangement of D major, I don't see how that's relevant to OP's point. How does it benefit anyone? Just because two of the modes have been chosen by western music to be the dominant ones, doesn't suddenly make every other mode a subcategory of them. What is the point of saying "this is in D major", when the root of the piece is clearly in A. Bb may be an enharmonic equivalent to A#, but it's not A#, in the key of Bb. It's D major in the sense that it is enharmonic, but it is not D major. IMO anyone would be better off spending a few hours learning how to do it yourself though. But I can see a simpe app produicing result for very simple music if people want one. To me that's a process requiring some intelligence that is beyond apps at this stage, it's basically AI. And it's highly context dependant and sometimes none are more right than the other. Then there is a lot of music (including some of my own) where you can interpret the harmony in many different ways, and you just pick whatever is more useful, not more right. If you've looked at the tempo of basically any drummer recorded without a click track, there is no-one tempo. The tempo I saw just told you one tempo for the whole song. On the other hand if you apply to it very simple music it can work just fine.īut even a lot popular music of the last 50 years has key changes. But I'm not going to argue with the market demand if there is one, just that such as a app is going to vague and approximate or just wrong. Well I'm assuming this a community whose knowledgeable about music, yes.
