Theres no real wrong way or right way to mix…there is only what sounds good and what sounds like garbage.
There are so many different ways to mix that there is no rule of thumb. Every Genre can be mixed but they may sometimes involve different mixing techniques.
A lot of it is trial and error…and thinking that you are going to master it in a short time is really naive…The more time you put into it the more you are getting it.
A few tips i would suggest is that when you are practicing, make mistakes, try using different things, do things going into it knowing you are going to screw up. Getting frustrated is a waste of time as it is very counter productive to what you are trying to achieve.
A big thing for me is that when i practice i NEED to be alone, I always feel that if someone is listening that i need to make it sound good and then i dont take risks and try new things.
When im refering to practicing…i mean when you make a mistake stop, go back and try to do it again…keep doing it over and over until you know it sounds good…then move onto some other tracks and do the same thing…having the ears to make perfect mixes and getting used to song structure doesnt happen over night…for some they have a natural talent and pick it up easy…for others its something they need to work on everyday.
Either way you will eventually get it!
