Mixed Voice

Technique

This isn’t another random set of singing tips.

It’s a complete and fun system I’ve tested with thousands of singers.

And it works—every time.


I know what happens when someone wants to sing better: they watch tutorials, try warm-ups, and wonder why nothing changes. The truth? You don’t need more random exercises. You need a step-by-step plan that builds your voice like a pro.


That’s exactly what you get inside Boost Your Voice.

A Complete System That Builds Real Singers

2 Levels of Training → Level 1 builds strong foundations, Level 2 pushes you further with more advanced control, speed, and style.

Professional Backing Tracks → 144 tracks produced like real songs, not robotic drills.

Tailored for Every Voice Type → Bass, Baritone, Tenor, Alto, Mezzo-Soprano, Soprano.

So no matter your range, you’ll feel at home—and challenged—in every lesson.

The Most Musical Vocal Exercises You’ll Ever Do.

Every lesson is designed like a mini-song. Fun, challenging, and laser-focused on skills singers actually need. Theory video, practice video, vocal examples and visuals. All of it full of pro tips to build your voice up for the challenges of the main exercise.


And before you start, you’ll also diagnose your voice type with my proven method for checking your vocal range. You’ll know if you are a Soprano, Mezzo-Soprano, Alto, Tenor, Baritone, or Bass.


That way you can choose the right professional instrumental tracks made exactly for your range—and even explore higher or lower types to expand your vocal range and push your development further.

Why it Works?

Because it’s not theory—it’s tested.

Each exercise combines technique + artistry, so you don’t just practice—you sound better in real songs, real performances, real life.

Trainer, artist, visionary, professional, wonderful person.
I came across Jacek 6 years ago. I didn’t want to cancel my son’s lessons, who was away on vacation, I showed up once and I stayed until today.

It was one of the best decisions of my life. Singing lessons with Yazik, in addition to technical skills: widening vocal range, improving diction, learning proper breathing, give me energy, joy and, above all, also gave me courage and faith in my own abilities.

I gained more confidence and learned how to express emotions in songs.

Yazik inspires trust (confidence) and gives a sense of security, for him there is no “it can’t be done”. This has allowed me to pursue various projects…

Being in this world shows me that it is worth having dreams and developing passions. For this I thank Yazik from the bottom of my heart and sincerely recommend him to everyone.

His dedication, knowledge, and personalized approach to each singer help those who work with him achieve remarkable progress in developing their vocal skills.

Jacek has a unique gift — he can pinpoint exactly what a vocalist needs to fully unlock their potential. He works like a precise mechanism, “pressing” the right buttons, resulting in noticeable improvement. Thanks to his support and insightful guidance, singers improve their craft and discover new possibilities in their voices.

YAZIK is also responsible for creating original arrangements for our concerts. His work on projects such as Tribute to Anna Jantar and Tribute to Jarosław Kukulski has played a key role in the success of these events. His arrangements not only highlight the beauty of the songs but also give them a fresh, engaging sound that resonates with audiences.

Additionally, Jacek serves as the chairman of the jury for JoseSong, the largest Foreign Language Song Festival in Poland. I greatly appreciate his commitment to this role, which requires not only expertise and experience but also a passion for supporting young talent and promoting musical excellence.

Working with Jacek is a true pleasure. His professionalism, passion, and dedication inspire not only vocalists but the entire musical community connected with the JoseSong Foundation. I wholeheartedly recommend him as a mentor, arranger, and top-class artist

He has vast and long-standing experience as a vocal coach; for nearly 15 years, he has been professionally involved with voice and its production, which is particularly evident during various university ceremonies, where he willingly performs with the choir he has been leading for many years. These performances are outstanding events of high quality, enriching every occasion and giving it a unique character.

He is an incredibly charismatic individual who attracts others with his innovative ideas, implemented both in groups and individually. His professionalism, passion, exceptional stage presence, great courage, spontaneity, and smile always captivate the audience and inspire others to take action. He combines musical competencies with social sciences, making him a unique and invaluable member of our academic community.

I consider myself very fortunate to have him among us, and I can wholeheartedly recommend him for any kind of collaboration.

Have questions? I have the answers!

Is the course suitable for beginners?
Yes – I explain everything from the basics. But advanced singers will benefit too, as I highlight often overlooked but crucial elements of warming up the body and voice, and debunk common vocal myths.
How long is the course?
You decide. After completing the course, you’ll understand your voice and create personalized warm-ups that really work.
Can I practice at home?
Yes! All you need is your phone and a few minutes of quiet.
Can I practice every day?
You definitely should! The course is designed for regular practice sessions
Does the course include tips on how to sing using different registers?
Yes! Each register includes both theoretical explanations and practical tips for using it effectively.
Are the exercises difficult?
The first exercises are designed to gently warm up your voice, get rid of hoarseness, phlegm, and tension, and prepare you for more challenging tasks. The bigger challenge will be the Long Scale exercise, where I’ll teach you how to use a wider vocal range and transition smoothly between registers. All this is so you can sing longer, build vocal endurance under the right conditions, and take on more demanding songs—without strain and with full awareness.
