[1] Helix induces an actual  “mathematical experience” in the listener; and it does this more intensely than any other musical work that I have found.

[2] What is the nature of the “mathematical experience” induced by Helix?

According to the OMS model, music stimulates a large number of musical “receptors” (also sometimes called “processors”, “mental-resources”) which react to various aspects of the music. Most of these receptors are primitive in nature rather than being highly analytical. They cover a wide range of human experience, for instance: “rhythm”, “contrapuntal”, “loud/soft”, “high/low”, “harmonious/dissonant”, “spiritual”, “religious”, “ordered/chaotic”, “symbolic”, “emotional”. When a large number of these receptors are stimulated in a systematic way, the effect on the listener is massive and deeply satisfying.

There is a category of receptors which are “mathematical” in nature: They detect/signal effects of music which (informally speaking) are “mathematical” in nature. For example, there are receptors that detect/signal “componentry”, “formulas”, “structure”, “topology”, “infinite/finite”, “simple/complex”, “order/chaos”, “architecture/logic”, etc.  These receptors are quite primitive; and their reactions represent a mathematical intuition or reaction rather than a precise mathematical analysis. From the listener’s point of view, when these receptors are stimulated, the listener has an actual mathematical experience, to a degree: The listener will experience “componentry”, “formulas”, “structure”, “topology”, “infinite/finite”, “simple/complex”, “order/chaos”, “architecture/logic”. For an average listener, this experience is not up to the level of a professional mathematician, and these experiences may be somewhat inaccurate if evaluated from a formal mathematical point of view. But this is besides the point – it is still a rich and satisfying part of the musical experience, and although primitive, it is still “genuine”.

These receptors are “truly mathematical” in the sense that even a professional mathematician has these same receptors; and some mathematicians will at times make use of intuitions or primitive thoughts to assist them in their actual work. Of course, in many cases of course a mathematician’s intuitions are more acute than those of a non-mathematician. But when these receptors are stimulated, the listener literally partakes of an actual mathematical experience – primitive, but genuine.

As per the above, Helix enables a listener to partake of an actual mathematical experience – not as extensive as that of a professional mathematician, but genuine as far as it goes. What is distinctive about Helix is the high degree to which it stimulates the key mathematical receptors that are sensitive to music.
 

[3] Some detailed comments on the mathematical experience in Helix:

Components: There is a bewildering variety of componentry in this work. At times, I think of flotsam scattered on an ocean – a tremendous amount of random “stuff” with no obvious relationship (but then again maybe it is related?). E.g. at the beginning we hear rhythmic pulses from various percussion (different pulses, varying), and then a piccolo playing against a contra-bassoon (two strange and different melodies). Probably the composer has designed relationships among all these different things; but if so, the relationships are not highly-evident (it is up to us to intuit or suspect that there are relationships).

Formulas: We sense that things are moving, accelerating, compressing, in some kind of ordered/mathematical way – although we cannot articulate what the formulas are. (Compare to seeing a very slow whirlpool in a large body of water – there is a sense of formula, but only a scientist or mathematician could determine what formulas might actually be involved.)

Structure: The work seems to be highly organized and unified from beginning to end.Salonen describes it as a “nine-minute accelerando” with two phrases “being pushed through constantly narrowing concentric circles …”. It is “very rigidly structured, and based on essentially one continuous process.”

Topological: This work has a massive spatial aspect – the “helix” is a big evolving shape “in” the concert hall.

Infinite/finite: For the most part, the “helix” feels large and finite. But as it speeds up and compresses to its demise, there is a sense of a process that accelerates to the infinite.

Simple/complex: This work encompasses an exceptionally broad range on the scale of simple-to-complex. Simple: The work can be grasped as one idea, one “thing”, the “Helix”. Complex: The work contains a massive variety of components, and the complexity thereof (the way the components move and integrate) increases greatly as the work proceeds.

Order/chaos: The work feels highly organized; but when examined in detail it looks highly dis-ordered, chaotic. As the work evolves, both of these impressions are intensified (it feels even more organized, but the detail seems even more dis-ordered).

Additional comments from Salonen: “The form of Helix can indeed be described as a spiral or a coil; or more academically a curve that lies on a cone and makes a constant angle with the straight lines parallel to the base of the cone.” (This language sounds like language from the abstract of an article in a mathematics journal).
 
[4] There is more to Helix than only a mathematical experience:

[a] It is a “celebratory and direct overture-like piece” (Salonen).

[b] It is flattering to the listener: Atonal, very complex and “mathematical”, melodies that are difficult to grasp; however it is designed so that an ordinary listener can easily perceive the major elements – the work is enjoyable even on first hearing.

[c] A termination which is easy to grasp and even fun: The listener can witness the piece terminate/self-destruct in a gigantic acceleration – a death spiral that hits a big brick wall! Once the listener realizes that the termination is taking place, it becomes fairly clear that the accelerando stretches all the way backwards to the beginning of the piece.

[d] Rich detail: Orchestration and tone color. And there what seems like an overwhelming amount of melodic material:  A great variety of 3 and 4 note phrases that are joined into longer phrases and melodies. The melodic lines are relatively simple in terms of rhythm and shape (mainly small, singable intervals); but I also find them “unfamiliar” and difficult to assimilate. So Helix is fairly easy to hear on the “macro” level but elusive on the detailed level. As the piece proceeds, the detail becomes increasingly complex and “overwhelming”; but the macro level if anything becomes clearer and simpler.

Having listened to a recording many times, I am now able to focus more attention on the detail, and I find it very interesting.

[e] Helix is appealing and even “user-friendly” – but the appeal is without much use of conventional methods (such as emotion, melody, drama/narrative, harmonic structures, etc.). Salonen makes use of less-used kinds of stimulation (mathematics, “ideas”, novel colorations, an individualistic working of simple against complex, his invention of “the Helix”, the death-spiral, …) and gets a compelling, memorable result.
