You LOVE singing!
You sing at home, on stage, in a band, in the shower, in a choir, in the car, on the bike, in the recording studio...
Being the artist that you are, you crave freedom.
You want to sing across different styles: Jazz, Pop, Folk, Rock, Soul, Country, Latin, Balkan, Classical, Flamenco, Gospel… You want to break boundaries! Create your own style, dammit!
You don't want your voice to be at the mercy of destiny!
You want to have control and feel confident singing the songs you wanna sing. Keep your voice in shape and use it in a healthy way without compromising the sound you need or want.
Master your mix, fix that hole in your head voice, growl from your soul, or belt your face off, baby!
...and you know that there's more to vocal artistry than just vocal techniques.
You want to grow your musicianship and storytelling, find and expand your unique strengths and your signature sound.
You have come to the right place if you:
• Feel like you don't sound like you would love to.
• Feel overwhelmed when it comes to navigating your way through the abundance of information about the singing voice and exercises to choose from.
• Have been studying vocal techniques on your own like crazy, but find it difficult to apply the techniques and concepts you've learned into your own singing.
• Find it difficult to establish a practice routine.
• Feel frustrated when things don't work well and don't know how to troubleshoot yourself.
• Feel like your voice is out of shape.
• Are struggling to find your voice and would love to have someone guide you in the process.
"I’ve been singing for more than 20 years: released albums as a rock singer, did an acoustic solo project, sang in musical theatre, performed and toured with a 10-piece Latin party band. When I had to sing 4-5 gigs in a week, or do a recording session, I was always struggling with muscle tension. I wanted to sing with power, but without all the struggle.
Sing Everything was my first experience ever in taking a voice class online, and it was really good! Within the first 15 minutes of my first online class, I completely forgot I was in an online lesson, and felt like I was sitting in the same room, at the same table with Katja.
I learned using my support muscles, and became aware of how to make very powerful sounds without any discomfort whatsoever. The results were immediate, and it was really great to hear the results in other singers' voices too. I also enjoyed working on modifying the vocal tract, and learn how to access more harmonics. I really like how my voice sounds when I’m applying all of these things!
As a teacher, I can pass these new tools on to my own voice students. Both beginners and experienced singers that I teach were blown away by the breath management tools, and are now more confident in their own voices!"

Hi! I'm Katja.
I'm a singer, musician, singing teacher and voice technician.
I draw from a strong background in music education and vocal pedagogy, an eclectic training in various music styles and vocal improvisation, and experience as performer and theatre maker.
Over the past 20 years, I've been a singing teacher and vocal coach for aspiring and professional singers and actors, a theatre maker and vocal coach for talent development productions at the TheaterTalentLab, a Complete Vocal Technique teacher, a music education trainer for teachers at IFEN in Luxembourg, and voice teacher at Codarts University of the Arts music theatre department in Rotterdam.
I'm passionate about helping singers find their own voice, communicate with presence, power and artistic freedom. My mission is to help you find your own voice and maximize your potential as a vocal artist and performer. Together, we'll explore your possibilities so that you can gain full artistic freedom to choose your sound and deliver your message with confidence.
If we haven't met, get access to my free Inspiration Library for Singers here and join my free Facebook group here, so you can know my work.
Here's what other singers are saying:
"I'm now adding new songs to my repertoire with much more confidence, I know that I can do it! Now it’s easier and faster to find out what I have to do in order to sound in a specific way. And I also developed a more kinaesthetic sense: I feel that I am now very connected to my body and aware of how to move and fine-tune very specific parts. I loved the layered approach of tuning the vocal tract, one part at a time.
Sing Everything was amazing! It was like having Katja in my own home! It’s super comfortable too: you can immerse yourself in deep study while being at home in your pyjamas and slippers! And it’s not like you’re spending time with your computer, but you’re connected with other people around the world who are sharing exactly the same passion for the voice as you have. What could be better than that!
Ayelen Insua, Argentina
"I've performed and recorded for years. At some point I noticed I started putting songs in lower keys, because it felt more comfortable for my voice. Sing Everything has made me ready to make full use of my vocal range. Now I have more control, especially over the use of the whole wide spectrum of tone colors that my voice is capable of. Not only do I have a better understanding of my instrument, but also more possibilities for musical expression."
Estrella Acosta, Cuba / USA / The Netherlands
"Before working with Katja, I did not know why I was doing certain exercices, and I couldn’t apply techniques into my songs. I wanted to learn techniques to improve my “mixed voice”. After having worked with Katja, singing became easier. I learned better breath support and became able to reach high notes with more ease. My voice doesn’t "flip" anymore, it’s more stable."
Carole Sénecal, Canada

"I used to regularly become hoarse, especially after speaking for long periods of time, after a busy choir rehearsal or a long teaching day. My voice always had this weak link.
Until I worked with Katja. Since I started taking lessons with her, my voice can handle much more! I can teach long days, speak and sing: I’ve never lost my voice again!
What’s great about Katja is her broad knowledge that goes beyond Complete Vocal Technique, as well as her very personal coaching style. She always finds a way to teach me in a way that I learn the best."
Félice van der Sande, The Netherlands
"Katja is a great and enthousiastic teacher, with deep and detailed knowledge of the voice and how it works. I find her lessons inspirational and I recommend her strongly. She’s the kind of teacher that makes you sing the songs you never dared to sing and has solutions for every ‘problem’ along the way. Inspiring!"
Margriet Sjoerdsma, The Netherlands
"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 organizing 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 Katja is so great because she can really help you with a variety of things. She has knowledge of so many things, researches 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, The Netherlands
