    Let's hear what they are saying about Ilka's Music

    Thank you soooo very much for sending me your music meditation. It’s absolutely gorgeous and stunning. It really moved me and I could feel it deep in my heart center, so beautiful. I’m blissed out after listening to it!!!

    -Tracey

     Your work is amazing!!! My daughter has severe anxiety with flying. Yesterday she flew to Miami. In preparation I shared your recording with her. When she landed she sent me a text and said that she listened to your recording three rounds and it helped her get through the flight. Thank you so much for sharing your gift with me.

    -Rose

    Your voice is so beautiful and spacious, it is touching my heart. I can tell many people will love this song.

    -Linling

     I want to tell you that I have been addicted to your overtones for days now. It has taken me to really cool places, very quickly. I’m not able to lay in bed all that often, sometimes I have anxiety to do so. The other day I got in bed and listened to your overtones three times back to back. While I did, my body was moving and feeling fantastic. I picked up my phone with my right hand, which I can’t usually do. It was a very soothing, comfortable place to be! I want to pass on a big-time thank you and job well done.

    -THOR (Healing from MS)

    I was at last able to listen to your absolutely transcendent, ethereal, angelic and delightfully absorbing overtoning. Such a beautiful celebration of sound and harmony. And pure healing intention… at least, that's how I perceive it to be. Thank you for sharing this with me. I truly love it.

    -Tom

    This is incredible and really soothing. What a gift!
