Inner Space: Brainwaves Yourell Theta Vary Speed Simple

This is a classic theta brainwave entrainment sound made by two sine waves. The pitch shifts gently to produce some slow variation of the actual speed of the pulse. You can use it as a track and add voice (like relaxation or visualization), or just use as is to promote deep relaxation or trance. The pulses are about 8 hz (cycles per second).
