The Parkening version is in a book called Romanza with a catalonian song and the anonymous romance that everybody already knows. This transcription is a very difficult piece, especially the middle part, but it's so beautiful that it's worth the trouble. Rumores de la caleta means 'sounds of the seashore' and the rythym always makes me think of the waves coming up on the beach and the water trickling around the rocks. I can't find any numbers anywhere in the book to order it by, but the publisher is Antigua Casa Sherry-Brener Ltd. of Madrid. The copyright is 1973 so I'm sure it's still under copyright.
After the opening E chord, the fingering is like an E chord but moved up a fret, and the base line is C-D-B. The legato run is a-b-c d-e-f g-f-d in triplets. Does that help any?
