This piece is conceived as an étude on hidden polyphony, partially inspired by the works for solo strings by J. S. Bach. It also draws on an extensive exploration of natural harmonics.
Una furtiva lágrima forms part of a series of solo string pieces comprising Lágrimas (2014) for cello, and Jardín de lágrimas (2014), for violin. This work won unanimously the 1st Prize at the "Viola’s 2014" Composition Contest, organized by the Association Franco‐Européenne de l’Alto. Its first performance was given by Grégoire Simon at the CRR de Paris, France on 5 April 2014.
