Listen to a sample of the recording of Precipitaciones by Miquel Bernat
The piece should be performed with a sense of urgency and haste. Several of the sections in this work are melodic lines with long, rapid intervals which demand constant movement over the full range of the instrument: this is one of the major challenges of this work and, in my opinion, one of the greatest technical difficulties posed by the instrument. The first section is a good example, with the challenge consisting of combining this shifting technique with a series of equidistant chords.
Throughout the work, elements of periodicity and identity often appear and must be well played to structure the timing of work. A good example of this is the section in which eighth notes are related to eight different dynamic markings (from ppp to fff), and eight periodicities. When, at some point, the eight different notes are concentrated into a “B” only (while retaining the parameters of eight dynamics and eight periodicities), this gives the impression that the notes/heights are sustained by an effect of auditory habituation.
