Man, this goes hand in hand with another post I just made, about the physicality of playing and how that ultimately impacts note choice.
I suppose I slightly differ from your opinion that the baroque era had an infinite depth of creativity. While I do believe this era of music was insanely creative, and had a level of quality and depth that may never be replicated, when I studied this music I found it to have qualities and literal rules that would prevent some of my favorite music from existing.
In music school we learned these rules, such as: never use parallel fifths, contrary motion is always preferable, you must not have a tritone when spacing intervals save for a few deliberate cases, never leap more than a 6th unless it’s an octave, key changes must be led to by certain chords, etc. there is a whole library of these rules that come from almost exclusively Bach’s catalogue (might be wrong on that (as well as a few of these rules, it’s been awhile) but he certainly is responsible for a bunch). These rules were either made by Bach, or came from studying and analyzing music like his.
I guess just setting rules in the first place is contrary to my idea of limitless creativity. And I’m sure these composers broke them now and then when they saw fit. And ultimately, these rules were made to avoid sounding “bad”. I do believe they make sense; when shown examples of deliberate rule breaking for the sake of education, I did agree they sounded pretty bad. Idk if this is one of “those” rules but for instance, having a melody resolve and sustain on the fourth while on the tonic chord, in a major key, sounds almost objectively terrible.
But I’m sure Bach or a Bach student would have a heart attack if they did a proper musical analysis of songs from Underoath, Humanity’s Last Breath, Periphery, Bon Iver, Glass Animals, etc. which are five of my all time favorite bands (off the top of my head- a panic chord used in an Underoath song would never happen in a baroque song). Maybe I’m wrong and it checks out, I’d have to further my education and do an analysis lol.
Since there are things that to me sound objectively good and bad (i guess that’s kind of an oxymoron, but I didn’t want to use subjective. Just to drive home that I can’t understand how anyone could think some of these things sound good e.g. the major 4th example) I think that the way to go is to learn the rule book, and then throw it out the window. Maximize your knowledge and understanding of music, rhythm melody and harmony, and then set the rules aside and write whatever the hell you want to. That way you know what you’re doing, and are writing straight from the heart. In my mind, good music is whatever music makes your brain release dopamine, and meticulously following a set of rules is only limiting potential.
Wow, this turned into a really long post replying only to one aspect of your comment. I gotta learn to be more concise lol
