This binaural/monaural study aid features many different frequencies between 4 & 14 Hz. It begins at 4Hz and rises slowly, ending with a 14hz beta tone at around the 50 min mark. The pitch remains constant throughout. Adjust the volume accordingly and feel free to mix with music, though it is advised to spend some time adjusting to the tone by itself first.
