WOW! i just want to say THANK YOU so much for giving me such CLEAR explanations of how to sing well and how to master mixed voice! I actually have a vocal performance degree and I have never understood mixed voice well or had this much hope for me to develop it the way I want to! You have given me LANGUAGE to be able to communicate what I’ve been wanting to say so much better and I am excited to share all this knowledge with all of my students”

Pioneered by the World’s Leading Mix-Belt Vocal Coach

Sophie Jolls Founder of 1108 Vocal Studio • Creator of The Mix-Belt Method

For the past 20 years, Sophie has helped 47,000+ singers understand their voice and sing with greater confidence through The Mix-Belt Method. She’s coached Grammy Award artists, Golden Buzzer winners, recording artists, worship leaders, and thousands of everyday singers, while certifying voice teachers around the world.

Today, she leads one of the largest online education platforms dedicated to contemporary vocal training, with 175K+ Instagram followers and 80K+ YouTube subscribers.

But after working with thousands of singers and certifying voice teachers, Sophie noticed something that changed everything…

Most voice teachers had plenty of exercises, techniques, theories- knowledge.

They just didn’t have a system.

So Sophie created a diagnostic framework that identifies which ingredient is missing, why the voice is getting stuck, and exactly what to do next.

That formula became The Mix-Belt Method.

Mix Voice Isn’t Built With Exercises Alone. It’s Built With The Right Ingredients.

Great teachers don’t just collect tools—they instinctually know which ingredients their students need and exactly how to build those ingredients.

Before The Mix-Belt Method

Collecting exercises & techniques from Reels, YouTube, and different teachers… and spending hours trying to piece together conflicting ideas
Teaching every student the same way because you don't have a clear framework for what each voice actually needs
Relying on your own voice as the benchmark, instead of truly diagnosing your student's voice
Not confident teaching the opposite gender
Knowing how to mix yourself, but not sure how to explain it to someone else
Investing in private coaching and certifications that help, but still leave gaps in your understanding
Using the same methods for years but students aren't progressing further

After The Mix-Belt Method

Diagnose what's happening in your student's voice
Identify the missing "ingredient" preventing progress
Confidently coach the opposite gender
Follow a clear system with a personalized roadmap for every student
Instinctually know what your student needs and how to help them master their mix

“It Finally Clicked”

Real voice teachers discovering the missing piece to confidently teaching mix voice.

Chesney Allen | truvoicestudio

How Chesney went from “I didn’t know what to do with mix” to transforming students she’d been stuck with for years

Before the Mix-Belt Method

“I’ve taken courses, mentorships, and observed countless voice lessons… but I never felt clear on what to do with mix.”

Learned the information — but it never fully clicked.
Had students she'd been teaching for 2–3 years who were still struggling through their break.
Didn't realize some of her coaching cues were actually reinforcing the problem.

Then Everything Changed…

“After watching just the first half of your course, my whole teaching career changed entirely. I was taught almost ALL of this in previous training… but something about your teaching made everything click and clarified so many things.”

Breakthrough #1

A Student Stuck for 2 Years…

The problem

Couldn’t navigate an octave jump without his voice breaking.

“His break was sooooo bad.”

The Solution

She applied the NG Hum and Bouncy WAH with Vocal Fry from The Mix-Belt Method™ Curriculum.

The Result

“OMG. Like magic. He was singing so heavy, and I didn’t know I needed to have him lighten up… This one change has been amazing.”

Breakthrough #2

A singer she’d taught for over 3 years…

The problem

The breathiness improved…but the break never did.

Then Chesney realized something…

“I’d accidentally created a squeeziness problem. It was MY fault.”

The Solution

Instead of adding more compression…

She introduced more healthy breathiness exactly where it was needed based on The Mix-Belt Method™.

The Result

“I’ve seen so much more ease in her voice… She can hit the higher notes with more ease instead of squeeze. I’m just literally in awe.”

The Student Breakthroughs Were Just the Beginning…

The biggest transformation wasn’t just in her students.

It was in her confidence as a teacher

“Thank you for this program. I don’t know what I would be doing without it!! I charge $50 for a lesson (we live in a very rural area so this is actually a lot for local people) but am considering raising it because of the results I’m getting. Seriously amazing! (I mostly teach online now because of kids)”

I’m Ready to Confidently Teach Mix

Teachers Who Found the Missing Piece

“I love that these courses are affordable. These courses have helped me grow not only as a vocal instructor, but also in my personal growth. One thing I have noticed that has helped my students understand mixing better is mentioning the staircase. The majority of my students haven't heard of mixing/pharyngeal voice and so explaining to them what it is using The Mix-Belt Method™ helped immensely.”

You have given me LANGUAGE to be able to communicate what I've been wanting to say so much better and I am excited to share all this knowledge, excercises and techinques in their language with all of my students.”

“I found this course when I was at a real crossroads, where I was considering giving up on being a vocal coach. I felt huge imposter syndrome and didn’t feel clear on how best to help my students. Not only has this course given me so much new knowledge and an excellent structure to work from, and solved so many problems in my own voice as well as my students, but I’ve also felt SO seen and validated by Sophie sharing all of her experiences of her own coaching journey. She really does a great job of demystifying a lot of info that feels kind of gate kept in the singing community. I could not recommend The Mix-Belt Method™ enough.”

Anna Ryan

★★★★★

“worth EVERY SINGLE PENNY. I've been able to help my students achieve more vocal power and projection WITHOUT injuring themselves. My main background in singing is through a classical lens, and this course has challenged what I thought I knew about how to sing and sparked further curiosity on just how capable the human voice is. It has tremendously helped me in my own ability to mix as well. I used to strain and struggle with pitch when trying to sing It was frustrating. Now, I can sing any pop or musical theatre song with less strain and vocal fatigue, and more vocal projection and clarity than ever before”

Casey Lyra

★★★★★

“one of the main reasons I bought this course (along with just wanting to feel more confident in my own mix and ways to teach it better in general!) has been to better help male singers as a female teacher. I seem to have gained a few adult male students and they all have this same problem - but some of them are very much in the belief that it's either chest voice or falsetto (which they think IS head voice...) so I'm having to do a lot of work around their beliefs on that too. In fact, your intro video around helping students to re-align their belief systems about their own voice has made me realise this is precisely what is happening here and that I need to go a little deeper with them on this. Thank you for the course and making it so clear and easy to use for ALL voices - it's really helping me both as a singer and a voice teacher to identify areas of weakness and how to tackle them with confidence.”
