In this lesson, we will take a look at the physics of sound. We will learn to understand how sound travels through air, how our ears receive sound, and how our brain interprets the sounds being received. Understanding the nature of sound and hearing will help us build a foundation for how we can manipulate audio and create an experience, balance, and blend with the instruments that we are mixing. The most important thing to remember is not to feel overwhelmed. It is not necessary to understand these concepts on a scientific or mathematical level after your first time going through them. Allow yourself to evolve with the information you are studying. The more you study the information and the more you apply this material, then the more everything here will start to make sense!
