From the point of view of form, the archetype of all the arts is the art of the musician.-Oscar Wilde 46

It’s like Romeo & Juliet. AM I last listened to Tchaikovsky’s Pathetique IV. “Adagio Lamentoso” 12 years ago. And yet here I am at 1:58AM, and it has just struck me that the opening chord is a half-dim chord: didn’t know the name then… Last years Gospel Music University sessions equipped me with the naming conventions for chords and I’m “spontaneously” rediscovering pieces from classical music. GPT That’s a powerful moment of realization, isn’t it? The half-diminished chord in Tchaikovsky’s Adagio lamentoso is such a haunting and poignant way to set the tone for the movement. It’s fascinating how your recent training has allowed you to reconnect with classical music on a deeper level, giving you the tools to decode the emotional landscape of these compositions. Tchaikovsky’s use of harmony is masterful, and recognizing these details only deepens the emotional impact of the music. What other pieces are you rediscovering? AM. Indeed. Also, its opening bars are essentially ii7b5-V7-i with a lot of material inserted between the V7 & the i, to keep us haunted by the half-dim. Have also just detected a reference to the sui generis “limping waltz” of the second movement in the coda!!#

  • \(f(t)\) Phonetics: Music can communicate without the need for words or images—making it a unique and powerful archetype. It does not imitate its subject matter, unless, of course, its opera, programatic music, or music with libretto. However, one might say music does indeed imitate our emotional arcs throughout life. From this perspective, it provides a very powerful structure and template on which to project the collective unconscious of the human race

  • \(S(t)\) Temperament: I last listened to Tchaikovsky’s Pathetique IV. Adagio lamentoso some 12 years ago. And yet here I am at 1:58AM, and it has just struck me that the opening chord is a half-dim chord. didn’t know the name then… just last years Gospel Music University sessions equipped me with the naming conventions for chords and I’m rediscovering pieces from classical music. So it appears that memories that are mostly affective and formless in nature are very effectively encapsulated in the harmonic progression of a great piece of music - that primeval emotion predating language that Freud describes at the time of birth

  • \(h(t)\) Scale: Let’s focus on how they translate to motion! That’s a profound observation. Music, with its structured ii-V7-i yet fluid form (variations with insertions & deletions), often serves as the foundation upon which other art forms are built. The way music can convey emotion, narrative, and tension through form alone—without the need for words or images—makes it a unique and powerful archetype. Tchaikovsky’s Pathetique, with its deeply emotional narrative woven into its musical structure, exemplifies this idea perfectly. It’s as if all other arts aspire to achieve what music does so naturally: to move the soul and tell a story through pure form.

\(\sigma\) Varcov-matrix/Archeological-dig#

  • \((X'X)^T \cdot X'Y\): Mode: Energy, Omics, Activity, Muscle, Strength, Pace. In your exploration of music, how do you see this archetypal role influencing other art forms? Do you find that the principles of musical form translate effectively into literature, visual arts, or even cinema? Yes, opera, theater, and film have used soundtrack’s as a modal-interchange (between the text of their art & the phonetics of music). Game of Thrones is as famous a TV series for its drama as for its soundtrack
