The metaphorical impressions that the word 'Vortex' conjures up may well draw the intrigued listener to undertake a 'sonic inquiry' on the 'Kármán vortex street effect' phenomenon. In fluid dynamics, a 'Kármán vortex street' is a repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid around blunt bodies, causing them to vibrate. If the vortex shedding frequency is similar to the natural frequency of a body, it causes resonance.
The compositional idea of the "Kármán Vortex" album lies in the interaction between several sonic fields, imagined as an 'experimental orchestra' where elements such as noises, pulses and vibrations blend togethe forming a rich and complex sonic tapestry. The shape of the opus evolves through a constant transformatio
and timbric manipulation, and does without traditional elements as melody, harmony and rhythm. Rather, it reassesses and revaluates them by putting forward actions, shapes, weaves and 'energy vortices'. All these contribute to generate a sonic image.
The "Kármán Vortex" album is inspired by a collaboration with composer and Aeolian Harp maker Mario Bertoncini. The "Kármán Vortex" project was unveiled at the 50th Nuova Consonanza Festival in Rome (Italy) on November the 17th, 2013.
