What if your voice was free from tensions and strain, and you were able to sing and express anything you want?

What if choosing singing exercises was easy, and you would know exactly what to do next?

What if it was possible to achieve your personal vocal goals in less time, AND have fun while doing it?

Does any of this sound familiar?

You feel overwhelmed when it comes to navigating your way through the abundance of information about the singing voice and exercises to choose from. You don't know where to start!

You've been studying vocal techniques and vocal pedagogy on your own like crazy, but find it difficult to apply the techniques and concepts you've learned into your own singing and teaching.

You read the Complete Vocal Technique book, took a CVT introduction workshop, or some lessons, are super excited about what you've learned, but don’t really know what to do next.

You took a Complete Vocal Technique course, can work the basic concepts and techniques, and would love to dive in deeper.

You find it difficult to fit practice time into your weekly schedule.

Singers from all over the world are meeting in my Online Classroom since 2014. From Germany to Canada, USA to UK, Ecuador to Turkey, The Netherlands to Lithuania…

I created my Online Classroom because I know the POWER OF LEARNING TOGETHER.

It's FUN, and you LEARN A LOT FASTER than if you'd be studying alone!

Why struggle on your own when you could be learning together with other like-minded singers and teachers in a positive and supportive environment?

Your Instructor

Katja Maria Slotte
Katja Maria Slotte

Katja Maria Slotte, BMus, MMus, Authorised Complete Vocal Technique (CVT) Teacher, and voice teacher with 20 years experience, is known for her personal, "out-of-the-box" teaching style, and for achieving lasting results.

Her clients include professional singers and teachers, performers and recording artists, aspiring singers and performing arts students. Originally a native Finn, Katja teaches in The Netherlands where she currently resides, as well as internationally. Her teaching commissions include lessons and workshops for the Dutch Academy for Performing Arts, ArtEZ Conservatory, and Fontys Rock Academy. As a teacher-trainer Katja provides music education courses for Institut de formation de l’éducation nationale in Luxembourg.

Drawing from a background in music education and extended studies in vocal pedagogy, Katja is a dedicated teacher committed to providing singers, performers and teachers the highest level of training.


"I love the course! Very good course and a very good teacher! Singing became more easy. As a teacher, it gave me A LOT OF TOOLS and very easy exercises and easy ways to explain things."

- Carole Senecal, Singer & singing teacher, Canada

"Katja’s teaching is very inspirational and out of the general singing teaching box. I have worked with other singing teachers, and they were all more or less delivering one style of teaching. Katja has got many ways of getting solutions to one problem, her teaching is very diverse.

After having participated in Katja’s online course, I lost fear! I guess in every singer, because your instrument is a part of yourself, there is a lot of possibility for fear. But if you work together with other people, you lose this fear, since you allow yourself to make bad sounds in front of others. It’s so relieving, it makes you so strong as a learner.

Katja’s goal exercises helped a lot, and have changed my work ethics and my work structure. To be honest – after her online course, I had a structure in my work for the very first time in my life! And that’s a great feeling.

- Tamara Pientka, Singer & Voice Teacher, Germany


Over the past two decades I've worked on my own singing goals, and taught thousands of singers. I noticed some common underlying denominators in much of the frustrations and struggle related to singing practice.

We need to know WHAT to do, but we also need to know HOW to do it.

Then, we need to become STRATEGIC about practice. FOCUSED, CONSISTENT practice on smaller details yields greater results than looking for quick fixes now and then.

We grow faster in a POSITIVE LEARNING ENVIRONMENT. It's also been proven that ACCOUNTABILITY leads to higher success rates.

"I joined Katja’s online classroom because I wanted to know more about the CVT techniques, and be able to use them in my own voice in a more conscious way. I learned a lot and I am very satisfied with this course! Finally I found my ‘head voice’/Neutral, and I can even vary with sound color in it. The course helped me enormously with my breathing, so many things became clearer. I had a lot of discoveries in my voice during this course and keep discovering even after it. I am much more confident during singing now, even on stage which is very important for me. I can hit higher notes with more twang, and I can explain much more about the voice to others, it’s amazing!"

- Liana Rudak, Singer, Lithuania

Speaking of value: at my current teaching rates, you'd pay €5896 for this amount of lessons with me. And that wouldn't even include the 'red phone style' access and all learning materials. But don't worry, this program won't cost you thousands of euros!

"Over the years I have followed lessons with Katja, and have been coached by her not just in vocal technique, but also in teaching, performance, planning for major artistic projects - and actually in life in general.

For me, Katja is like a barrel full of knowledge and inspiration from where I can draw whenever I feel stuck. Whether it's a voice related thing, a question about a student I teach, or organising my work better - after a lesson with Katja I always have new ideas and insights, and it always helps me to get unstuck!

Besides being a good advisor, Katja is for me an accountability partner, and above all a very smart, sweet and funny coach. And a real voice nerd! I think working with her is so great because she can really help you with a variety of things. She's got knowledge of so many things related to the voice, studies different approaches, and is open to many perspectives. In addition to that, she is reliable and really looks at the person she's working with.

I believe you can't wish for a better teacher."

- Evelien Storm, Singer, Songwriter & Voice Teacher, The Netherlands


A collection of randomly selected vocal techniques and exercises that you have to navigate on your own.

Each week will be dedicated to a special focus. Vocal technique topics that we’ll cover are breath management, airflow and support, twang, working on the 4 vocal modes, as well as modifying sound colour. You will connect the main topic of the week to your own singing and current goals.

A curriculum where everyone has to do the same exercises at the same time.

While we'll follow a general curriculum over the 8 weeks, it's YOUR goals and questions that really form this course. Everyone in the group is working on their personal vocal goal(s) at their individual level. In the additional live Q&A's there is time and opportunity to dive into additional techniques, and questions rising from the individual goals. These might be connected to vocal effects, vocal health, teaching, or performance goals.

A “song learning course”.

Instead, during this course you’ll really internalise the techniques so that in the future you can work them in any song you choose!

A course where you have to sing predetermined repertoire.

You’ll be free to choose what songs you work on, but are encouraged to connect your choices to the structure of the curriculum and the focus of each week. That way a very deep learning experience will be guaranteed for all participants. In order to avoid overwhelm and dive deep, I'm also encouraging you to keep the amount of songs you'll be practicing during the 8 weeks to a minimum.

A course for complete beginners.

This course is open for singers on different levels. Given the intensity of the course, it's important that you have either previously worked on your voice together with a teacher, or gained basic understanding in how your voice works through self-study. If you're doubting about your level, please schedule a free call with me to find out if this course is suitable for you.

"Katja always puts the student in the spotlight. It's all about YOU and how she can help you the best. She is empathetic and objective at the same time, which makes you feel very comfortable as a student."

- Floor Horninge, Singer and music teacher, The Netherlands
