Monitoring the Mix
27. Listen to your music at moderate levels in your car or on a boom box. This is how most of your fans will listen to it, and mixing at loud levels will fatigue your ears and distort the "true" sound.
28. Sometime it's good to take a day off and come back to listen. The same applies for mix-down. Ears don't last very long in the studio.
29. As you review each mix, make sure you can comfortably hear all of the instruments. Tweak the mix on a small pair of speakers at an extremely low volume. Headphones are also very valuable at this stage. You should be able to pick up each instrument even at this level.
30. Learn to recognize ear fatigue. You're better off quitting a session early when you're tired than wasting time making a bad mix that will have be redone anyway.
