Joaquin Turina's lovely fragment "Sinfonia del Mar" from 1946 is worth hearing. It is up on YouTube, which surprised me greatly, as Turina was in his final illness and only composed the first two movements. I had the piano score, from which it was clear that he intended to orchestrate the work, but I was unaware that he actually had done so, much less that anyone had ever played it! Aquarelles are fairly frequent in Turina's output. He also has a piano suite called "Viaje Maratimo" (Sea Journey) whose opening motive is marked "Tema Americano", and in the lovely suite "Mallorca" is a piece called "Noche de la Bahia de Palma" (Night on the Bay of Palma).
