Opere Sonore


Opere Sonore

The Company E. Ciresa Srl was founded in Tesero-Trento in 1952 by Enrico Ciresa (1922-1991), after long years of experience and skills gained in the manufacture of Delmarco and Bozzetta pianos and harmonium, and the prestigious Schulze Pollmann of Bolzano.

At the beginning Ciresa produced keyboards and harmonium reed pianos of various sizes, and its models were soon known for quality and sound throughout Italy.


The strategy of the company Ciresa, was to inform the general public about the existence of this very special “Tree of Music” and its history, which came out in the name of Antonio Stradivari, who personally chose the Fiemme trees to make the soundboard of his famous violins, from which he received a great sound.

Fiemme spruce – tonewood

In the Dolomites area, supported by the best climatic conditions, the trees grow very slowly, ripening their precious wood for musical instruments made then by skilled hands of violinmakers, all over the world.

Among thousands of trees, only a very small quantity can be selected for its fine and perfect grain and for its natural acoustic properties.

In our factory every step and every gesture come from tradition, experience, skill and passion.

A unique artifact

It is always exciting to know that a Ciresa soundboard vibrates in the heart of the best violins and pianos in the world. Passion and experience can enhance the peculiarities of the tonewood: this is the origin of Opere Sonore.

It is not a work of magic, it is an Opera Sonora.

Magic balances of thickness, sound and shapes: Opere Sonore are carved to charm, to fulfil a dream, to touch and leave a sign.


It is the first shape designed and tested by Fabio Ognibeni. The idea was born thinking to the wind which accompanies, day and night, the life of the forest blowing among the spruces. The point stretching to the top imitates the leap of the tree towards the sky and the curving lines seem to capture the wind like a sail swelled by the energy of nature.


The Opera Sogno expresses the research of an evolution of forms and materials, that coexist in a sinuous ensemble of absolute lines and curves. As result of a very refined design by NTY Line, it represents a mask which expression is mainly music and form. The Cube Bass is made of tonewood and devoted to low frequency

America’s soul

This Opera Sonora is a tribute to the American people.

America’s Soul is elegant and sophisticated. It vibrates in a powerful and direct way, surrounding the listener in a strong musical whirl, enriched by the harmonics of the tone-wood.

It is fated to record a very important step in the evolution of this innovative sound mode, born with the creation of Opere Sonore.

The wooden stand, hand carved and varnished, is inspired by the American big steel frame-works of the thirties’.

Soundboard made of high quality Fiemme spruce, special selection of tone wood grain.


It represents the trunk of a tree, which cut-off branches are stretching upwards.
The longest pieces of spruce transmit through their grain the highest sounds , while the wider area below, main body of the trunk, fills the bass tonalities and completes with force the mix of the notes.

Del Vento

Inspired to the lines of  Lamborghini’s sport cars, it was created in 2010. Its name recalls speed and aerodynamics.

Modern and attractive, it spreads the music from the sharp lines of its soundboard and finds its best placement in a minimal and design furnishing.

The stand, designed by Luca Degara, recalls the steel pipes of the exhaust manifolds of Lamborghini’s engines.

Dimensions and weights: 1040 x 700 mm  -> 930 g
Transducers: 2 pieces, specially produced for the Opere Sonore project.

The music is expressed by the succession of the curved lines moulded in the wood. This Opera Sonora is characterized by the fullness of the sound, pouring generously from its heart. The waves convey a pleasant aesthetic look and give life to the shape, that seems to glide from the top edge to the depth of the surrounding space.


It is structured by a set of simple lines, unbalanced towards the top. The sequence of the holes, main characteristic of its design, is inspired to the celestial bodies set out on the orbits of the sidereal space. The name comes from this layout, in contrast with the warmth of the sound, whenever performing blues or jazz pieces.
