The Impromptus, Opus I, is a selection of compositions written between 2015 and 2021. The numbering, I-VII, is chronological, and the impromptus themselves are inspired by events in the composer’s life. The music follows an improvisational style that incorporates musical influences ranging from the Classical and Romantic periods, Russian romance, Ecuadorian pasillo, tango, blues, and jazz. Homages in various forms are present in the work. For example, the allegretto at the end of Impromptu No. 3, composed after the death of the composer’s grandmother, and in the months following the catastrophic earthquake in the Ecuadorian region of Manabí, alludes to a melody from the region’s namesake pasillo.

Each impromptu is an autonomous work. Impromptu No. 1 is formulated from a melody that the composer played as a child, while Impromptu No. 2 is perhaps the most improvisational piece of them all. Impromptu No. 4, the “FCD" Impromptu, is purposefully divided into seven sections and always switching into a different F key. The waltz-inspired Impromptu No. 5 marks a midpoint in the collection. No. 6, indicated as adagio lamentoso, underscores a feeling of melancholy before transitioning into a maddening subito presto section. The last, ImpromptuNo. 7, was composed immediately after No. 6 and shortly before the composer left Ecuador.
