There are 2 types of brainwave entertaintment frequencies/music- BINAURAL & ISOCHRONIC. BOTH these sound frequencies are used to align your mind into a certain state - it was primarily used for enhancing meditation but has since been used for almost almost all areas of personal development. Isochronic tones are similar to binaural beats except you do not need to use headphones - it is essentially a higher quality sound product and you can listen just through your speakers!
There is also A free Visualization Video with isochronic tones with visualization, printed affirmations, and subtle hypnotic patterns to naturally alter your brain state in link provided. PLZ read instructions fully (use headphones for mp3/ video 4 maximum results )
