My understanding is that Indian music uses pretty much the same tones and semitones as European music... occasionally however chopping them in half. The ragas are IIRC much like what European music calls modes.
The first sentence is sort of vaguely correct (as long as you keep in mind that the actual tuning is very different), but the second is oversimplified to the point of being wrong. Rāgas are often compared to modes, but they’re really ‘more than’ modes: they consist of, not just a pitch set and a root note, but sets of melodic contours, conventions for which notes follow which, ornaments, and so on, none of which is part of the Western conception of ‘scales’ or ‘modes’.
I think Western music is more like that than you think, especially in its origins. E.g. Wikipedia defines a mode thus (emphasis added): "Its most common use may be described as a type of musical scale coupled
with a set of characteristic melodic and harmonic behaviors." And it goes on to quote Aristotle:
But melodies themselves do contain imitations of character. This is perfectly clear, for the harmoniai have quite distinct natures from one another, so that those who hear them are differently affected and do not respond in the same way to each. To some, such as the one called Mixolydian, they respond with more grief and anxiety, to others, such as the relaxed harmoniai, with more mellowness of mind, and to one another with a special degree of moderation and firmness, Dorian being apparently the only one of the harmoniai to have this effect, while Phrygian creates ecstatic excitement.
Oh god; this is excessively bad even for Wikipedia. The Ancient Greek ‘modes’
are not the same thing as modern modes. (Despite the latter having confusingly been given their names.) Aristotle is not talking about modern Western music! Western modes are rather a scale + a choice of root note, or equivalently a sequence of tone/semitone sequences from some starting note. The mode alone implies very little about melody, though it implies more than a scale does.
(Source: I play jazz music. Admittedly I’m a drummer, but I’ve picked up a lot and done a fair bit of research on my own.)
Classical Western music does have "conventions for which notes follow which"; we just call it something else, harmony. If you're a classical composer writing in D major, you can't just randomly write notes, you're following a bunch of rules.
I think you misunderstood what I meant by ‘conventions for which notes follow which’: ragas are actually associated with
specific melodic contours (or melodic fragments, you could say) which must be used in any song in that raga. I’m not denying that Western music has rules! But this is something which deserves to be elaborated on in more depth…
(Warning: looks like I wrote another essay — sorry! I hope it’s all ended up clear.)
So: harmony is something very different to any concept in Indian music. (I see rotting bones agrees.) In fact, I consider it nothing less than the unique defining feature of Western music theory, which distinguishes it from Indian, Chinese and other music theories. Of course all music theories have rules which must be followed, but the actual rules are very different, as are their effects.
Let’s try to be precise here: what defines harmony? To me, it builds on top of intervals, which are pairs of notes. Certain intervals sound
consonant, and others sound
dissonant — these being technical terms specific to Western music theory (and which have changed meaning over time; they are grounded in physical measurements but only to some extent). I’m sure there’s similar concepts somewhere in Indian music theory, but they’re far less important, the reason being that Indian music tends to be monophonic. By contrast, Western music almost always have multiple lines of music going on at once, so they need to sound good together. (We reify such more-or-less consonant subsets of notes as
chords.) The goal of harmony is, basically, to make sure that notes which are close together are consonant, or conversely to strategically create tension and interest via deliberate dissonance. In Western music this is extended even to monophonic songs: you can always write down at least a bass line which is implied by the harmony, which isn’t just ‘stay on a single note indefinitely’ (as is the case for Indian bass lines, played on the tanpura).
(Also, Western harmony involves movement between different chords: this is really important and I discuss it more below.)
There is an additional wrinkle in Western conventions: we like using
absolute note values. This is why you can contemplate a ‘classical composer writing in D major’ in the first place — even though there is no aural difference between D major and C major and G# major (at least since the introduction of equal-temperament tuning), we still like to identify notes by reference to a standard pitch (usually 440 Hz, as I’m sure you know).
Leaving that aside, it’s clear to me that ragas and harmony are restrictive in different ways. As I said above, ragas restrict the melody itself, and its emotional tones. By contrast, Western music lets you write almost any melody with almost any emotional meaning in any key or mode (the nearest concept to a raga) — Pachebel's Canon sounds nothing like Hotel California, but both are in D major.
In exchange, harmony gives you a different restriction: at any point in a song you are restricted to a specific
subset of the possible notes, which sound good with each other. If you have a song where some part of it has Cmaj harmony, you can’t unrestrictedly use a D note there, because that’s a horrible dissonance. What you
can do is move to Gmaj in the next part of the song, which has a large overlap with Cmaj but allows D. This repeated movement is what gives Western music its interest: even a tune like ‘Twinkle Twinkle Little Star’ discernibly moves between two or three chords. (That’s also what lets you write a bass line for it, as mentioned above.)
This has many consequences, but there’s three which I want to highlight here:
- Constant harmonic movement means that you can modulate between different keys: simply move through a chord / subset of notes which is common to both of the keys. And you can do this again and again and again, limited only by your imagination in finding tricky subsets of notes. By contrast, in Indian music, it would be inconceivable to switch ragas in the middle of a song even once.
- The extreme of Western reliance on harmony is reached in songs like Jobim’s One Note Samba, where the melody stays on only one note while the entirety of the interest lies in the harmony. (Admittedly it can’t stay on one note for the entirety of the song, but it’s pretty close.) This is the polar opposite of Indian music, where the tanpura (bass line, as mentioned) stays on a single grounding note while the melody moves around dramatically within its own constraints.
- There is one subgenre of Western music which I feel is closest to Indian music. This is modal jazz, where the entire song has only one or two chords in the harmony, held for long periods of time. The natural consequence is that there’s much more focus on melody — not to the extent of Indian music, but you can certainly tell how certain notes become very highly charged with feeling given their contrast with the background.
(My favourite examples of modal jazz are probably Freddie Hubbard’s Little Sunflower, and John Coltrane’s brilliant version of My Favourite Things. You can compare the latter to the non-modal version made famous by The Sound of Music to see the difference.)
One nice summary of this which I once saw somewhere: ‘In Western music, you can make the audience gasp by moving to a different chord. In Indian music [and in modal jazz!], you can make the audience gasp by moving to a different note.’ Oversimplified, of course, but I think this gets to the essence of the difference.
For some reason the multiple modes of medieval music were lost, leaving just major and minor scales-- though even today these have differing emotional and not just arithmetical associations. Ragas have kept their ancient variety.
I’m not an expert in musical history, but my understanding is that the loss of mediaeval modes is closely connected to the rise of complex harmonies. The above essay should have made clear why — as restrictions on harmony were tightened and elaborated, restrictions on melody had to be loosened to compensate. Otherwise there would have been too many restrictions, and music would have been impossible to write!
