Use the following brain frequencies as a guide. Listen to those whichever one or more of those frequencies for an extended period of time and you will see the effects. I've tried it and it works.

Delta waves: 0 Hz to 4 Hz (Slowest)

• Too much: Brain injuries, learning problems, inability to think, severe ADHD
• Too little: Inability to rejuvenate body, inability to revitalize the brain, poor sleep
• Optimal: Immune system, natural healing, restorative / deep sleep

Theta waves: 4 Hz to 8 Hz (Slow)

• Too much: ADHD, depression, hyperactivity, impulsivity, inattentiveness
• Too little: Anxiety, poor emotional awareness, stress
• Optimal: Creativity, emotional connection, intuition, relaxation

Alpha waves: 8 Hz to 12 Hz (Moderate)

• Too much: Daydreaming, inability to focus, too relaxed
• Too little: Anxiety, high stress, insomnia, OCD
• Optimal: Relaxation

Beta waves: 12 Hz to 40 Hz (High)

• Too much: Adrenaline, anxiety, high arousal, inability to relax, stress
• Too little: ADHD, daydreaming, depression, poor cognition
• Optimal: Conscious focus, memory, problem solving

Gamma: 40 Hz to 100 Hz (Highest)

• Too much: Anxiety, high arousal, stress
• Too little: ADHD, depression, learning disabilities
• Optimal: Binding senses, cognition, information processing, learning, perception, REM sleep
