His editorials appear regularly in frontpagemag. His monograph, Global Warning: I spend a lot of time on the deck of my country home studying birds and listening to their distinctive calls. But none of them produces melody.

Tristan thrumming like a nightingale—cum russino, as the 12th century poet Thomas of Britain described it in his Tristan—to attract and summon Isolde would scarcely have worked in reality. A sonogram display, used in analyzing the structure of bird calls, does not track a melody but a concatenation of syllables that simulates a few blips on a hospital monitor.

All of this got me thinking one day about melody. I decided to consult my dictionaries, if only as a preliminary step or rudimentary gesture toward comprehension.

After all, nothing prevents us from generating an organized sequence of notes which may strike us as a demonstrable sonic structure but which we would never hear as a melody.

This is neither music nor melody; it is politics of the dreariest sort. Similarly, the theramin-like language of whales cannot be heard as melody.

The issue is how we hear melody as a unique, modular configuration of sounds which are tangible and yet incorporeal, as if inhabiting an ethereal region between the neural and the spectral and eliciting a vast range of sympathetic response.

Of course, music in the fullest sense—tempo, pitch, timbre, the diverse scales, texture, 'colour,' counterpoint, their combinations and temporal relationships—is one of the great mysteries of human spirit and culture.

Its intrinsic components in their multiple arrangements, however, can be mastered. Did modulations in speech, David suzuki ancestors the genetic source thesis and vocatives eventuate in the reproduction of simple melodic sequences?

Or was melody—whatever it is—somehow there at the start, predating actual speech, inherent in the chromosomes, a genetic gift that can be either latent or manifest, depending on the individual or the culture? Or, as some may believe, is melody the hosannas of heaven filtering down to the fallen creature in his travails, subsequently emerging in the spirit?

Is this how Jubal, as Genesis 4: One may recall Milton in Book XI of Paradise Lost, who seems to refer to theories of speculative music musica speculativa that were in vogue in the 17th century.

The notion is that the music created by man on earth musica practica is an attempt to replicate the music of the spheres. Sometimes a melody seems to resemble a disembodied soul seeking a body to be born in, as in certain religious concepts associated with diverse Eastern faiths and some Western philosophical traditions, like Orphism or NeoPlatonism.

You can sense it on its way to its future home, plangent yet insistent, a kind of mellifluous urgency that announces itself as if it were fully formed and needing only to be properly received. Your job is to let it happen, to offer hospitality.

At other times, the melody needs to be sought, coaxed into existence, drawn out of its distal reluctance or fey mischievousness. There is some truth to this also. The only reason I kept flailing away is that I could feel the invisible presence of the melody, tantalizingly suspended somewhere beyond my reach—before it finally alighted on the strings.

Of course, sometimes accidents happen. It might also be the result of a cacophony of unrelated sounds—for example, one is slamming away at the strings or the keyboard in an access of pure frustration—from which a singable tune unexpectedly disenjangles itself, like a cellular mutation, a messed-up gene that leads to something complex and resilient: By which I mean not only how a melody comes to be but, as I continue to wonder, what a melody actually is, in effect, the very ontology of song.

Rhythm is theoretically understandable; a regular or syncopated beat, meter or the mensural unit of time, kinetic emphasis, are no doubt based on the heartbeat, the accentuations of the pulse over which rhythm is superimposed.

Arabic, Turkish and Persian music is fascinating, dancing maqam quartertones on the oud from which the European lute is descendedas in this piece by Persian virtuoso Yasamin Shah Hosseini.

But for the most part it is not comparatively melodic in the hummability mode. Tonal systems vary dramatically; yet, though all these systems will qualify as music, not all can be described as melodic. It may well be that the Western imagination is specifically attuned to the reception of melody from its undocumentable source—at any rate, melody in its more elaborate, sophisticated and memorable aspects.

I am tempted to say that melody as it has been heard, cultivated, refined and transmitted is one of the signatures of Western civilization, an aural distillate of its essence. I am by no means suggesting that other musical traditions are not valid and authoritative and beautiful in themselves, but I am proposing that melody per se, in its richest and most memorable form, was detected—and perfected—by the Western sensibility.

I will surely be accused of ethnocentrism in advancing such an hypothesis but it seems persuasive to me and at least worth considering. This is not, however, an argument I relish plunging into, and it remains at a tangent to my main thesis.

Hummability is the basic litmus test of melody.
