If you’re a doctor, you can’t operate if you do not know what you should and should not cut. If you’re a mechanic, you can’t repair a car unless you know how the engine parts work together to move the car.
As an engineer, you are a technician, but one that works with creative material. Yes, you can approach it purely like a technician, but you won’t be able to perform as well as if you know a bit about music. Notice that I used the word “perform” rather than work.
We work with sound. We work with music. We work with feelings. If you don’t know anything about any of these things, you have no business calling yourself an engineer.
If you only know about sound and not music (and more importantly the feelings that music can express) then you may be able to spit out work that looks good on a meter, covers all the requirements, but has no musicality and feeling. In addition, you need someone to translate what the musicians say so you understand what’s happening.
The best engineers are IN THE MUSICAL MOMENT ALONG WITH THE MUSICIANS and can discuss not only things like sound volume but also things like sound dynamics, harmonic or rhythmic support, musical timing, and instrument functions. The best engineers recognize, encourage, and capture musical creativity.
“The main job of the recording engineer is to capture as much musical dynamics as possible. The mixing engineer should utilize those dynamics to enhance the expression of the song.”
Dynamics refers to the interplay and “give and take” between different instruments based on their changes in volume or other characteristics.
Dynamics means change, which can occur on many different levels. Even a single instrument can have dynamics that change over time.
There is emotion in dynamics. When someone speaks loudly, it impacts you one way, but if they speak softly, you find yourself listening harder and perhaps even leaning in to hear better…this greatly changes how you will perceive what you are listening to. This is an example of dynamics as applied to volume.
Dynamics not only applies to volume but also to any other kind of change or movement such as tonal change, intensity (how hard one plays), rhythmic feel, etc. Sounds can have different dynamics at different frequencies.
Dynamics can be felt in single instruments, relationships between instruments and even the combined sound of a finished mix. Although these days everyone seems to want their music as loud as possible with no break, music often has important dynamics between instruments that help to convey the emotions of the song that can be lost when mixes are squashed and pumped for the sake of volume.
You do not have to know how to play an instrument or read music in order to push a fader, but it really does help to know what the musicians on the other side of the glass are going through.
