Seirén o el canto extraviado (Seirén or the lost song) is a stage research project that aims to review the figure of the siren – in its conceptual, mythical and contemporary dimension – and how it has evolved from its origins to the present day, generating as a result a transdisciplinary performance that mixes voice, sound and audiovisual experimentation. The main axis of this revision consists in the fact that in the first known stories the sirens enchanted sailors with their voice, which gradually disappeared in contrast to the importance that has been given to their sexual character. It is worth noting that in Homer’s Odyssey, the sirens not only try to seduce Ulysses with the beauty of their voice, but above all through the lyricism of their songs, which appealed to the hero’s ego through the vainglory of his exploits. This is why we consider that this song has to do not only with the quality of the sound, but also with its content. This element is fundamental and reveals a patriarchal standardisation in relation to the female voice or the woman’s voice. Why does her voice cease to be significant and become only an aspect of pleasure and sexuality? When does the logos cease to be allowed in the woman’s voice and is relegated only to the phonic?
