Abstract: A device for inducing better sleep embedded with music having a tempo of about sixty to about eighty beats-per-minute. Listening to music with a tempo of approximately 60 to approximately 80 beats-per-minute results in significantly better sleep quality, better perceived sleep quality, longer sleep duration and greater sleep efficiency. Embodiments of the device can include, among other things, an alarm clock, a pillow, mobile, sleep mask, crib or a stuffed toy for use with children. Embodiments of the device including a travel clock, travel pillow, or mobile device allowing the device to be easily transported for purposes of inducing better sleep during travel are also contemplated.
