learning about neutral, supermajor and subminor chords, zheanna erose's yt is such a great resource
another awesome resource has been the art of mixing. i'm learning so much about the process and going further in depth than the format of a 20-minute yt video allows (not that yt hasn't been helpful too of course)
oh ya plus i'm doing a trial of sonarworks, which EQs your computer's audio output according to your headphone model in order to create a flatter frequency response curve. i think it's made a noticeable difference in the quality of my mixing!
anyway, lots of music progress lately, it's exciting!
