i have typed and retyped a one million word response to this thread like three times now, but i think this type of response is easier at the moment. i can also say that someday in the future you will be able to hear @fourhexagons and i talk about this subject very much more at length.
the only very core thing that i can really say is consistent across the board for all artist you mentioned and is very basic but also critical : play in key.
i can only speak for myself but - very much completely intentional. composing is full of exploration and “happy accidents”, but the final recording is always a product of making changes based on my knowledge and heart of music to create what feels true. my beginning process is to pick a key, tune my sound sources to the root note (on modular with the v/oct CV plugged in but not moving, set also to root note), select my scale notes, program them into sequencers, start listening, and start writing. it’s really usually lots of simple relationships. 3rds and 4ths and 5ths and octaves. weird pop music! rhythmically i tend to like clusters of sounds not always snapped to any tempo grid that phase in and out with each other nicely… that’s just something i listen for. some have also mentioned drones. drones that add and subtract harmonics throughout can really give a piece a lot of life and mass.
tune (^^^) play in key
explore sounds, try to emulate the ones you like, go slow
(reverb and delay)
this i think gets more about sound sculpting and mixing.
i am inspired by the philosophy and design of monome which is why i use their devices, but for me the tools don’t have much at all to do with the sound or the theory. sequencing on the grid is tactile and i like the human interaction. it’s intuitive and easy to brainstorm ideas on quickly. teletype has near endless possibilities. but the sound of the music that i want to make is very similar on all types and brands of instruments/synths… modular or non modular. electronic or acoustic.
very similar (shared?
) emotional intention which i think is the most important. and playing in key
(also one of these people worships the circle of fifths * cough @fourhexagons * , ones loves minor, and i think all of us love 5 note scales)
others have mentioned this but i really think that the importance of listening can’t be overlooked. neither can practice. every piece of music you have ever loved is revealing to you why it sounds the way that it does if you just listen. and also i think you have to spend thousands of hours practicing music in many different ways… not because you are putting the time in, but because you love it. everyone starts at 0. i’ve spent almost every day of the last 10 years playing and practicing and absorbing and learning music in some way whenever i can, and every day i am an absolute beginner and i want to go deeper within my musical self. like others are saying, theory is helpful but there is no magic formula. this type of music is really simple actually. beyond my basic knowledge of theory i don’t really think about it too much, i trust my ears and my heart more. i have no formal education beyond barely getting a high school diploma. you certainly don’t need to be beethoven.
i hope this is in some way helpful and in line with the original question and not just mind barf. surprisingly a very difficult topic to respond to i think mostly because i find myself unable to stop writing lol.
