Eléctrico (Electric) is a piece from Diez Piezas Fugaces (10 fleeting pieces). The 12/8 time already suggests it: This is a piece with a clearly swinging bluesy atmosphere that would not be out of place on a steel string guitar. The ornamentations -slides on two strings- require some practice and the chords require attention.
In the end you will have a swinging piece with some nice blue notes.
