With academic erudition and supported by extensive experience as a repentista, the author proposes a study of the improvisation of the décimas following a method that allows us to appreciate both the beauty and the poetic complexity in this stanza frequently used in popular Ibero-American poetry. As Díaz-Pimienta points out, improvisation is “an art so complex and so unknown that it should be tempting to researchers.” This volume is an original and necessary proposal to address new studies of the improvised décima, as well as an invitation to the reader to discover poetic findings in ancient forms that continue to be sung throughout the pan-Hispanic territories, from the expert hand of a born researcher.
