My Sonic journey


My name is Petra Crnetic Dvojkovic, I was born on the 28th of March 1977 in Zagreb, Croatia. I am involved in music all my life. Since I was 16. I started composing, engineering, arranging, and producing music. For 15 years, I was a studio owner and producer. These skills helped me later on in self-producing all my sound therapies.

Apart from my fascination with sound and vibration, I have a big passion for life, humanity, and human consciousness. This curiosity leads me to master and work with different energy, body, and mind techniques (Reiki, Ho’oponopono, Tesla Metamorphosis, different types of meditation, conscious breathing, and Body Technique).

Before my formal education in sound, for ten years, I was doing a lot of self-education, research, and experimental work. Since 2018, I am a member of the Sound Healers Association after training in sound healing at Mr. Jonathan Goldman's Healing Sounds in the US. In 2021. I graduated from Sound Healing Academy in GB.


Working with sound made me realize that it could be used as a perfect tool for self-improvement in many different directions to help ourselves live a more quality everyday life. Through the usage of sound, we can bring ourselves to a wanted mood or state and change a state of dis-ease into a state of ease. and balance. 

My research and experience, over the years, led me to develop a specific methodology of working, and this method  I call The Blackbird method. This method is the basis of all my sonic therapies and products.

In 2017 I developed VOICEFLOW - a personalized sound therapy created on the basis of frequencies that are extracted and analyzed from one's voice.

In 2018. I created and launched an application called Soundhealz for android and iOS  (WWW. SOUNDHEALZ.COM ).

In 2019, together with my partner Lara Ljubičić we formed Sonic Group Ltd company and launched our first product called WWW.SONICPILLS.EU

Sonic Pill has been recognized as innovative in the field of new technologies and becomes a multi-award-winning product on international fares in Nurnberg (iEna 2019.), Seoul (SiiF 2019.), Warsaw (IWIS 2020.) and Zagreb (Arca 2020.)

My work is my mission and passion. For years I have successfully worked with hundreds of clients, and I am continuing to research and experiment with sound on daily basis in order to develop new techniques and programs.
