Sleep For People, 1-hr (Micro SD Card, Download)


Sleep gently lulls the mind and body to deep, restful repose. A psychoacoustically-refined Adagio movement from Mahler’s extraordinarily sweet and calming Fourth Symphony delicately unwinds into a soothing sound bed of slow lapping ocean waves. Sweet and simple melodies float in and out in lulling rubatos. Sleep is a tranquil cradle of sound in which to find rest and renewal.
Sleep features a chamber ensemble with woodwinds (flute, clarinet, oboe) and string section (violin, viola, cello, and bass). The SD Micro sound card can be played on any of the iCalm 2.0, 3.0, 4.0 or 5.0 players.

Choose between micro SD sound card, CD, or Downloadable files to keep and play on your favorite devices.

Please note: The micro SD card features 1-hour soundtrack is followed by 10-hrs of silence to make sure you are not re-awakened by the music track auto-repeating. The Download files are meant to be played once each, in succession, and for your natural environment sounds to carry you through your sleep (no REPEAT function on).

Track notes

Because iCalm players have an auto-repeat function, an extra track of 10-hours of silence have been added at the end of the music/ocean track to keep the listener from being awakened by repeating music. The architecture of the first cumulative 1-hour track is designed to slowly bring the listener down into lower heart rate and brainwave states and leave them there for a good night’s sleep. The tempos and orchestral densities do not bring the listener back up to normal waking states. This is left for the body’s natural function.

Ocean sounds have been used in this track for both masking of external noise, but also for the entrainment effect (our primary pulses speed up or slow down to match an external periodic rhythm).
