"Big To Small" mixing is a technique that I talk about in my book, Three Dimensional Mixing, and it's also something I utilize every single day. I don't give advice that I wouldn't give to myself, in fact, I think big to small mixing is a great technique for anyone to try.
So What is it?
Below is a segment taken from the SECOND EDITION of my book, where I talk about Big to Small mixing. This is the first section from the new book shared anywhere on the net!
BIG TO SMALL MIXING: IN A NUTSHELL
This technique centers around the idea that mixes are NOT a creation of random sounds. They are songs. They are instruments playing a song. It doesn't matter how many mics you used to create that sound, all that matters is that it's an instrument. I see way too many mixers diving into a mix with guns blazing, filtering this and that, compressing this and that, soloing up channels, doing all kinds of ridiculous small picture stuff. We don't want that. We want BIG PICTURE. We want the song to sound like a song.
Pros of Mixing Big to Small:
1) Your mixes come together quicker.
2) You use less CPU.
3) You use fewer plugins and processors in general.
4) You retain context of the song constantly.
5) You are organized and can make easy changes to your mixes.
6) You will likely have tighter phase relationships due to fewer individual channel processors
7) You will likely worry about the right things and ignore the irrelevant things.
Here are your guidelines:
1) Work quickly, and try to mix at a normal to quiet level.
2) Act on instinct. Act musically. React to your feelings. Don't read numbers or meters.
3) Avoid the solo button (for now).
4) Be organized. Name your tracks appropriately, color code, organize, group, etc!
5) Group things into as many groups as you need. Guitar group, Drum group, percussion group, BGVs, etc. If there are 3 mics on a bass cab, group them into a bus. If there's a "dry" and "compressed" chain on a vocal, bus them. If there's a kick "in" and "out," bus them.
6) Commit to working chronologically. Try not to jump around too much while mixing. Mix in passes. Start at the beginning and go to the end, tweaking as you go, without stopping, without soloing, without changing your monitoring level. Work on it like it's music, not like it's a photoshop project.
7) This technique is best suited for sessions that are clear. Meaning, if you were mixing along the way, this technique might not work as well for you. If you want to try it on an existing mix or one that has already been started, save that as a copy, and open the session up and clear it. Take off all the inserts, sends, panning, filters, EQs, trims, compressors, automation, everything. The only exception to this is if the insert is integral to the sound, for example, an amp simulator on a DI guitar track.
8) Make priorities. Who's the most important character in this song? Who is supporting actor? Who needs to be featured and who is simply an extra in the background? Every song has a different story, and so every mix has different priorities. Never lose focus on the most important things. (I'll give you a hint, the most important are probably going to be vocals, the main instrument, bass, and drums).
Now let's get mixing.
Step 1: Start with a basic balance of the song. We're talking 15 minutes tops, or about 3 listens through. Really it should only take you one or two listens through the song. Work those faders and pans. I like to start with my faders at -10dBFS, which gives me a good amount of room to go up and down. The first things I will push up (as you might expect) are vocal, kick, snare, bass. They usually get bumped a little bit right out of the gate. If you gain staged your session well, they should be sitting pretty happy together.
Step 2: Once you've got a balance that seems to be pretty nice, check out your master bus. How does the song sound overall? Is it going to need to be brighter overall? Is it too fat? There are two options here. If it needs to be brighter, feel free to add that to the mix bus. If it needs to be thinned out, save that for individual channels. In general I don't try to do much bus EQ, just a dB here and there if needed. Keep it light, keep it simple, and use a good EQ. Your entire mix is going through it. Don't use EQ if it doesn't need it. Next move on to compression. Does the mix need a bus compressor? Audition a few if you need to, and try to set it to where the song starts to gel a little bit. Sometimes 1-2dB is enough. Use your ears. What about saturation? Are you into tape emulations and the like? Add it if you feel like the song needs it, not just because you want to! Listen to the song as a song and the mix as a whole. Big picture.
Step 3: Once you've got the master bus situated, take a look at your groups. Drum group, guitar group, bass group, BGV group. etc. Basically everything should have a group. Listen to them as big picture elements. Do the drums need compression as a whole? Do they need some EQ? Do the guitars need some EQ or some widening? Do the keys need some filtering or compression? If so, apply these things to the groups as needed. You can be a little more liberal this time (as opposed to our conservative bus processing). If you want to group things further or use parallel processing, do so now. An example of this might be sending drums and bass to a parallel buss to compress them together as one unit and blending them in with the originals.
Step 4: Take a moment to pause. Are there any glaring issues that still exist? Anything you can't get over? Hopefully the dry sounds you got to mix were tracked well, but if there are any glaring issues, this is your chance to use your get-out-of-jail-free card here: you may now use the solo button, BUT...it's only to fix issues. Things like using de-essers on a vocal, filtering out unneeded sub information or room rumble or 60 cycle hum, filtering out hiss, severe boominess, pops, etc., removing noise, ringing, humming, etc., noise reduction or gating, etc. This is not a time for shaping things. It's only a check up. If there are any problems with the audio, fix them now. They should have been fixed in the tracking stage, but I digress.
Step 5: Once you've fixed any glaring issues (hopefully there weren't too many), give the song a listen from start to finish again and check your balances and bans. Again, when balancing try to work big to small. Need more drums? Turn up the drum bus. Still need more snare? Turn up the snare.
Step 6: Now that you've got a pretty good balance of the mix, you've worked with the master bus as a whole, the group channels, and fixed any glaring issues, then rebalanced, you're ready to start shaping the tracks. Again, commit to working big to small. Instead of reaching for a bell EQ, try a gentle shelf first. Use wide Qs. I can't tell you how to process your tracks in this stage. This stage is all about getting them to blend well together, and admittedly, it's a hard step, and it will be the longest part of your journey. A lot of novices start here and immediately try to shape the tracks together without getting a frame for the mix as a whole. You have to start with your foundation, build a frame, add the walls, put up the drywall, and THEN paint them. So go ahead, EQ, compress, add effects, do what you need to do. But always try to avoid the solo button, try to mix chronologically, and try to remember that you are mixing a song and not a collection of sounds.
Step 7: Once you've got a nice blend that you're digging, Automate your mix from good to great. Too many novice engineers avoid automation. It's possibly the most important tool we have for making mixes direct the listener's attention. We can manipulate what they're focusing on at what moment, who is important, who needs to take a backseat. We can jump out at them and grab their attention by automating up a vocal phrase or a drum fill or a guitar riff. We can suck out the low end on something only to bring it back later. We can add effects to a certain part. Truly automation is one of our best friends in the mix and you should use it. If you're not using it, you're probably wrong. Not everything needs to be full spectrum all the time, and not everything needs to be full loudness all the time. You need to give things little moments to be featured - they won't necessarily do it on their own. Not everything can shine the entire song - you need to give everything it's moment to shine so that it creates the illusion that everything is shining.
I hope this mixing theory helps you make better mixes. I know it may seem crazy to some of you, but this is exactly how I mix. Like I said, I wouldn't just make this up and throw it out there. Mixing big to small helps me mix quickly, effectively, and not lose sight of what's important. It helps me minimize my "tweaking" phase down to half of what it used to be, and it helps me use a lot less processing on my mixes in general. Nobody wants their stuff to sound overmixed, overprocessed, overtweaked to oblivion - it just sounds terrible.
