These six topics cover all aspects of music. Challenge GPT-4o or any other ChatBot to find a issue that isn’t seamlessly subsumed by one of these headlines. Perhaps what is most profound is that EmotionalArc is really an archetypal propensity for Pattern-Recognition amidst the chaotic mess of the universe. Its the basis of humanities sanity (when it works in constrained settings) & delusions (if patterns are seen virtually everywhere). And thus whether our fate is predetermined or we have freewill is very much an interesting question, with both sides being very heavily supported by empirical data from physics & chemistry (relativity, quantum), biology (quantum mechanics of DNA replication errors, complexity of systems), and society (the entire range of variables influencing humanity including fluxes in the in the cosmos, earth & our seething brains)#

Predicting the Next Token. Three minor (ii, iii, vi), two major (I & IV), a dom7 & a half-dim7 constitute the diatonic chords of western music in order of degree of tension they invoke in the conditioned listener. For these reasons, dom7 & half-dim7 are the strongest predictors of the next chord in any chord sequence (progression or non-progression). Because the composer, performer, and listener crave some relief. Minor chords are associated with the most ambiguity because there are three of them and thus more options when compared to the other diatonic groups. Major chords are intermediate in ambiguity. We can speak with a degree of accuracy that a half-dim7 resolves to the V7 especially in the aeolian mode. The dom7 will resolve to the root but or to a secondary dominant. Not to mention that there are two species of dom7: the one that resolves to a major (has extensions: dom13) and the one that resolves to a minor (has alterations: dom7♭9♯9♭13). So one might actually claim that dom7 is really two different chords and, thus, as ambiguous as the two majors. But the two majors do not strongly predict a next token since they aren’t very tense. They might be followed by yet another non-tense chords or by a tense chord.#

Aesthetic, Historical, and Cultural#

In the vast landscape of Western music, Bach, Mozart, and Beethoven stand as towering figures, each representing a distinct approach to the divine, the human, and the synthesis of both.

ii7♭5 \(\mu\) Mozart#

While Mozart’s compositions are often seen as effortlessly divine, seemingly channeling melodies straight from the heavens, and Beethoven’s works capture the raw, human struggle and triumph over adversity, Bach serves as the foundational architect—a composer who encodes all prior forms of Western music into his oeuvre, laying the groundwork for both the divine ease of Mozart and the transformative struggle of Beethoven.

V7 \(\sigma\) Bach#

Bach’s genius lies in his profound understanding and integration of the entire spectrum of musical expression available in his time. He mastered the phonetics of every major instrument and form—pipe organ, cello, clavier, violin, human voice, ensemble, and more—demonstrating not just technical virtuosity but a deep, almost scientific curiosity for the full range of sonic possibilities. This mastery extends beyond mere instrumentation; Bach was also a pioneer in exploring temperament, most notably through his work towards equal temperament. This was not just a scientific achievement but a cultural feat, allowing for a new kind of aesthetic expression where the constraints of tuning were transcended. With such ease, Bach navigated these constraints, achieving a musical fluidity that borders on the overman-like, an Übermensch quality. His Well-Tempered Clavier (WTK) is a testament to this exploration, dabbling in very specific scales in his preludes and venturing into the depths of modal exploration in his fugues.

In Bach’s Goldberg Variations, we witness a different kind of mastery—one of predictability and variation. Here, Bach plays with the very concept of ‘next tokens’ in music. We often know the chord progression before we hear the variation; we know the key. There’s a comforting predictability to some of his choices, yet each variation brings a fresh perspective, an unexpected twist within the expected. It’s as if Bach is both following a script and improvising beyond it, encoding an emotional and intellectual outcome that speaks to a profound understanding of musical form and structure. This foresight and deliberate playfulness create a dialogue between past and present, between what is expected and what is creatively transformed.

i \(\%\) Ludwig#

While Mozart channels the divine, producing melodies of such grace and simplicity that they seem to bypass earthly struggle, and Beethoven transforms personal and cosmic struggle into profound musical narratives, Bach stands as the “musician’s musician.” He provides a monumental example to composers in their struggles, a blueprint for the infinite possibilities within musical forms and structures. His work is a deliverance to the jazz and gospel artists who must improvise on the fly, offering a depth of foundation upon which to build. Bach’s compositions provide a deliverance from the script and note-based music of the classical world, offering instead a framework of encoded musical possibilities that can be endlessly explored and expanded upon.

In this sense, Bach, Mozart, and Ludwig together form a trinity of musical philosophy. Bach represents the monumental and foundational, the encoding of musical antiquity with a vision for future exploration; Mozart, the antiquarian and divine channeler of effortless beauty and grace; and Ludwig, the critical spirit of the overcomer, the human struggler and transformer of adversity into artistic triumph. Together, they encompass the full range of the human and divine musical experience, offering a roadmap for all who seek to traverse the landscape of sound, emotion, and intellect.
