On-line Extreme Vocal Lessons
A full‑scale harsh‑vocal training experience delivered through real‑time, interactive video sessions. No matter where you are, you get direct access to advanced learning methods and professional vocal analysis. Using reliable, high‑quality software, we break down your phonation, tone, and compression with precision. Train your scream, gutturals, and pig squeal straight from your home studio or rehearsal room — with the same intensity and depth as an in‑person session.
Live Extreme Vocal Lessons (Cracow)
Personal 1:1 sessions held in Cracow. Direct, in‑person work with a vocal coach gives you instant correction of your habits and technique. During live sessions, we precisely analyze your body posture, breathing mechanics, breath support (appoggio), and resonance. It’s the ideal format for deep, comprehensive work on the physiology and biomechanics of your voice.
Who are our extreme vocal lessons for?
Our training program is designed to meet the specific demands of extreme music. It is intended for:
Beginner extreme vocalists
People who want to build healthy vocal foundations from scratch, understand laryngeal anatomy, and learn vocal distortion safely, without risking damage to the vocal folds.
Advanced metal vocalists
Frontmen in death metal, black metal, or metalcore who want to expand their vocal range, optimize endurance for multi‑day tours, and improve diction clarity at extreme tempos.
Every enthusiast of heavy music
Musicians for whom extreme vocals are a passion and who want to consciously control subglottal pressure and sound dynamics.
Why learn extreme vocals with a professional?

Frequently asked questions about extreme vocal lessons
Does extreme vocals (growl/scream) damage your throat?
No. Properly executed harsh vocals do not use the true vocal folds to create distortion. Instead, we engage the false vocal folds (false cords) or the arytenoid cartilages (fry scream). I teach only 100% safe vocal production, with full vocal‑hygiene awareness.
Do I need to be able to sing clean vocals in order to learn extreme vocals?
It’s not required. Although extreme techniques and clean singing share the same fundamentals (such as proper breathing and resonance), the process of learning growl or scream uses a completely different laryngeal mechanism. We’ll build your foundation from the ground up.
What do I need to start real‑time online lessons?
All you need is a computer, tablet, or phone, a stable internet connection, a camera, and a microphone (the built‑in one is fine, though an external condenser or dynamic mic makes frequency analysis easier). You’ll receive all the remaining know‑how and the full exercise system from me during the session.
How long does it take to learn the basics of an extreme vocal technique?
“Every voice reacts differently, but thanks to my original methods and direct 1:1 mentoring, you’ll achieve your first repeatable, safe results and correct sounds after just a few sessions.
