These two pieces for guitar ensembles (with a total duration of about ten minutes) were commissioned by the Saint-Nazaire Conservatory (CRD) (premiere on April 5, 2025). The first is aimed at 1st cycle participants, the second associates them with 2nd cycle students, distributing the different levels of difficulty according to the desks. Their musical purpose lies in the evocation of impressions facing the sea, sometimes calm, sometimes agitated, through a thematic, moving and contrasting material, common to both pieces.
