The sad thing is that classical music used to be like this!
Beethoven would improvise for hours and bring his listeners to tears, and the classical concerto tradition of the "cadenza" was originally a time for the soloist to improvise and showcase his or her skills, finishing off with a trill to let the orchestra know it was time to move on. Additionally, it was commonplace for pianists to add their own flair to pieces they were playing, emphasizing or de-emphasizing elements, or adding extra musical content. (e.g., additional contrapuntal lines, turn some runs into octaves, replace some octave salvos with filigree., &c.)
In the late classical (Beethoven piano concerto #4 being the first prominent example) period, cadenzas started being written by the composer, and the composer's intentions started being seen as sacrosanct, a divine mandate from on high.
This slowly died off. Vladimir Horowitz was the last "great" pianist who regularly re-arranged the music was performing and, ironically, pianists today often perform his arrangements. (See, for example, the Rachmaninoff 2nd piano sonata, a hybrid of Rachmaninoff's two editions, which many feel is a better compromise between grandeur and thematic progression.)
Classical music was a lot more like jazz, but it has largely become a religion rather than just an art form.
Eliot Fisk has done a this relatively recently (~2015) with the Bach cello suites. Although they aren't improvised, they are re-arranged to take advantage of the fact that one can play more notes simultaneously on the guitar — to me they sound like warmer lute arrangements with some modern voicings. Definitely different than the arrangements I play.
This is getting off topic, but I cannot wait for the day when we will be able to transmit music from brain to computer. There maybe genius arrangers/composers who never had the time to master an instrument or software.
I definitely can wait. I love that music is a physical medium, requiring a body in order to experience it, not just cognition. That music originated with and continues to largely be based on human bodies generating rhythm and sounds either intrinsically, (singing, vocalizing, body percussion, stomping, etc.), or extrinsically using acoustic instruments. I also totally enjoy electric instruments and electronic music, as they don't necessarily imply losing the various embodied aspects of music creation and enjoyment. Which is to say, embodiment is something I feel is truly important for many reasons , and is one of the reasons why I love music (saying this as a musician, music lover, and temporary pilot of a mostly functional human body).
I love that to play an instrument with some level of proficiency, it takes physical practice. I love that to get good at dancing, sports, or martial arts - takes physical practice. That these things engage your whole beingThat part of the joy from these kinds of activities comes from the time that is invested, the changes and improvements that are experienced over time. I love that we have muscle memory - that our bodies can be trained to respond faster than our thinking mind in various situations.
To me, while it could take some cognitive work up front in terms of synthesis, composition, and arrangement - the otherwise instantaneous transmission of this product from thought to machine strikes me, at worst, as yet another technological solution for a problem that doesn't exist. Not to say that it would never be useful. Just srsly... do we need an app for everything that could ever possibly exist?
