Harp Glissando - Wind and Ocean Surf. Meditation and Relaxation Sounds. The magical tones of a harp being strummed, ascending and descending. Ten variations of glissandos spaced 15 seconds apart. Waves roll onto the shore in a cascading surf. Steady and pulsating, growing louder as they approach the shore as they break apart, then disappear. Sea gulls squawk as the wind ebbs and flows. The combination of wind and waves creates a tonal sweep of audible frequencies, making this recording a good sleep aid.
