It was 20 years ago when I saw the GlassDuo for the first time at the polish Percussion Workshop in Koszalin. I was very impressed by their playing and by this extraordinary instrument. After that I kept dreaming about having one myself. I was very happy when G2 Glass Instrument Makers began to build these instruments and I could finally buy one from them. I was falling in love with it right away! The concept of the glass harp Cumulus by G2 Glass Instrument Makers is absolutely perfect and it is very comfortable to play concerning tuning and range. It is a professional instrument perfectly build for stage and transport. The sound is inspiring and spacing. I would recommend this amazing instrument for everybody searching for a new experience, music adventures whether playing beautiful music for yourself or for an audience.
Thank you very much!!

At last I received my glass harp 1 month ago, and as a new musician not knowing how to read music I play by ear my favourite tunes. I always wanted to play an instrument but never found something that suit me... until that glass harp. I have so much to learn but really happy to climb that mountain and discover new things about myself. The quality of the material and sound is amazing, and the creators or G2 are following me every step of the way to make sure that I have a good start. Feeling happy to join the glass harp community, I only wish to be better at it and can only dream of a better me in few years. If I can reach only a tiny bit what these guys do I'll be super happy already. All the best for you Anna and Arkadiusz in this new adventure, keep pushing and enjoying what you do, I'll meet you someday along the road.

We bought Cumulus from GlassDuo recently. It is very high quality perfectly tuned glass harp. I really enjoy playing this instrument whenever I get time. With LED lighting, this instrument looks great for live and studio performances. This instrument sounds so soothing and calming.
