About Grotta Sonora

is a project for the design and construction of hand-crafted experimental musical instruments.
Madhava Carrara and Margherita Cioffi, artisans and musicians, started this project building on their personal experimentation with sound, using different types of metals.

Madhava Carrara is a musician, percussionist and artisan who was brought up in an environment strongly influenced by the Indian culture. He has being experimenting for years with the craft of making stringed, wind and percussion musical instruments, using a wide range of materials, including recycled waste materials.

With Margherita Cioffi, singer and decorator, he started the exploration that is at the foundation of this project.
Their first instruments were crafted in a cave (“grotta”) of Etruscan origin close to Calcata, an ancient village in the Treja Valley. The cave eventually turned out to be the perfect place to play these newly-crafted instruments, thus kicking off the Grotta Sonora project.

The harmony of the instruments make Grotta Sonora a true interactive gallery. Although it started as the home of an “ensemble” of unique instruments, putting people in touch with sound and its vibrations and combining hearing and visual experiences, the project is a process of continuous development and experimentation.
After an initial period in which we opened Grotta Sonora to visitors interested in seeing the cave and its sound sculptures, we recently decided to share our instruments and sell them internationally to the large sound healing community, while continuing to put creativity and love into our products.

Our vision is to create different sonic environments in unique locations around the world, recreating the magic resonance and harmony found in our Grotta.

In July 2019, the Grotta Sonora project participated as a gong builder in the first edition of the Gong Summit in Connecticut, United States.

This allowed us to present the Grotta Sonora vision and instruments to the American sound healing community and to some of the most important gong masters in the world.
