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.

He started with Margherita Cioffi, singer and decorator, 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.

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

the cave


Our first instruments were crafted in an Etruscan origin cave in Calcata, an ancient village in the Treja Valley closed to Rome. The cave 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 the cave , named GROTTA SONORA , a true interactive gallery. 


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, but the project is always in progress, It's a continuous development and experimentation process. 

In the first period the The cave was open to visitors, and after we decided to share our instruments and sell them also internationally to the large sound healing community, while continuing to put creativity and love into our products.


Grotta Sonora is a good location for concerts, and we are happy to invite artists with experimental projects to perform in our space.

Grotta Sonora is located close to Calcata, a charming medieval village, 47 kilometers north of Rome, overlooking the Treja Valley, once the bed of the Tiber river.

Calcata is also known as the “village of artists” and in recent years has become a thriving tourist destination.
