Árpa Eólica (Aeolian harp) is a permanent installation conceived for the Valle de Guadalupe, a Wine-growing area in northern Mexico that was covered by the sea, thousands of years ago. The piece is located in the middle of the field, on a promontory, and oriented in such way that it receives the Santa Ana winds as well as those that comes from the north. The decision to use the boats was for the way the acoustically these can function as resonators, but also to refer the time when that semi-desert area was covered by the sea.
An Aeolian harp is a musical instrument played by the wind, named after Aeolus, the ancient Greek god of the wind, and it is the only string instrument that plays harmonic frequencies.
The piece is based on a resonance box and four boats that works as acoustic resonators with 12 strings 24 meters long stretched along two bridges. The quality of the sound depends on many factors including the length of strings, the character of the wind, the material of the resonant body and atmospheric factors.
