"Preciosa" (English: Precious) is a 1937 patriotic composition by Puerto Rican composer Rafael Hernández Marín.
[4] Years later, in 1947, he returned to Puerto Rico and became orchestra director at the government-owned WIPR Radio.
[8] Preciosa expresses feelings of love and nostalgia for Puerto Rico.
It is considered one of the unofficial National Anthems of Puerto Rico[9] The work includes a celebration of the three historical sociological traits that Puerto Ricans attribute to making their current culture and nationalism; the blend of Spanish, African and Taino.
However, all Puerto Ricans, regardless of their personal beliefs towards the political status of the island, celebrate when hearing the song.
