This piece by Argentinian composer Honorio Siccardi reflects a charming and reflective character typical of mid-20th-century Latin American piano miniatures. It features delicate melodic lines that require a sensitive touch and careful voicing.
The main challenge is maintaining a consistent, lyrical melody line against a shifting harmonic accompaniment.
