Ferrer dedicated quite a number of his pieces to other people, like in this case his friend, the D. Apeles Mestres. Apeles Mestres was a Catalan writer that had contact with many composers of the Spanish School (Granados, Albeniz and others).
Horas Apacibles means Peaceful Hours, which is quite obvious in the collection that consists of Allegretto, Valse (3x), Andante (2x), Mazurka, Minué and Nocturno. The pieces require more practice that the ones from for instance Ramillete and Veladas Intimas. They are worthwhile, however, if you want to present a nice impression of popular musical forms in Ferrer’s romantic music.
