Within this context, Remacha's return to music took place through teaching and the composition of music for piano and for the Navarrese choirs with which he came into contact. In this way musical genres that Remacha had hardly dealt with prior to the war came to acquire considerable importance, since these were the works that could have the most immediate impact. Some of his piano works were based on a Bachian conception of music. This was the case with the "Prelude and Fugue in D minor" (1945), dedicated to Ricardo Urgoiti. Certain anecdotal circumstances explain the idiom used in some of Remacha's works. For example, the "Piano Sonatina" (1945) is a more peaceful work because it was intended to be performed by Urgoiti's daughter. At the same time, as a result of the contests in which Remacha took part and the commissions that were made to him, a regionalist component arose in his work which added nothing new to his compositions. Despite this, in all his compositions Remacha tried to assimilate this regionalism with his own traits. This may be observed in such works as "Cartel de Fiestas" ("Festival Poster") (1946) or "Rapsodia de Estella" ("Rhapsody of Estella") (1958), which are by no means among the best pieces composed by Remacha. Aside from this Remacha composed a large quantity of choral music which may be divided between original compositions and harmonisations or adaptations.
