40 Hz Music | Azure Skies | Deep Focus | Improve Memory

This calming and soothing 40 Hz Frequency Music is particularly helpful for playing softly in the background for work and study. It allows you to focus and stay on task, and better absorb and retain what you're studying or working on. **IMPORTANT NOTE** It is important that you listen to this song at a low volume. The 40 Hz frequency is very low, and when listened to at higher volumes will produce a pulsating "vibrato" effect that won't be ideal for listening. When listened to at lower volumes, that pulsating is less, and you get a deeper calmness and relaxation associated with the music. 40Hz has been found to be particularly beneficial to the brain. Many studies have shown that our brain cells communicate at a frequency of 40Hz.
