In music, an ostinato is a short rhythmic-melodic figure that repeats itself, often played by the bass. In jazz and pop, it is preferred to call it a RIFF, a formative energy that allows for unexpected variations. Let's imagine music as a sound building that - starting from an ostinato or arriving at it - travels in different directions, made up of full and empty spaces, spaces in which we happily lose ourselves. Paolo Damiani's scores are conceived as authentic mechanisms of bewilderment, in the desire to encounter the unknown, the unexpected, something that excites and surprises. He works by contrast, risking uncontrolled variations, senseless intersections, shaky chords. Contrasts such as whole/fragment, fast/slow, open/closed, vertical/horizontal, loud/soft, straight/curved, measure/excess, transparent/veiled: a "standing against" that ultimately becomes a project, in Franco Purini's splendid definition: "A project is any system of predicting a series of future actions aimed at producing an event". Not forgetting to be unreasonable when necessary, towards new imaginations, wonderfully unstable.
