the main reason they’re so different and really shouldn’t be compared (IMO) is exactly what you’re alluding to—playing an instrument is an inherently physical process. mixing/producing music is an inherently mental one.mcatalao wrote: ↑10 Jun 2021From my understanding, and having studied both aspects of the craft, the mindset for an instrument is a very focused one, very practical and with a very dive into detail, and it depends a lot on the depth of control of the instrument you intend to achieve. It also has a very physical component (muscle memory, positioning, for some instruments like any of the string instruments) you change your body posture for the instrument at a level where bones and muscles change. The pianist hands get squashed for the big hand overtures and so on.
However, there's something to say, the things you learn as an instrumentalist overlap with a lot of stuff that will benefit a producer, and the best producers most often play one or more music instruments.
you can’t play an instrument well until you’ve got the physical side of things down. you can’t produce a good mix until you have a good mental understanding of how to manipulate sounds.
composition is where the two start to overlap, mainly because modern production software has largely become synonymous with music composition. what you used to have to do 100% outside the box (with instruments or scores, etc.) can now be done 100% inside of it (virtual instruments and sequencing).
