The science
We separate established findings about music listening from promising—but still developing—ideas about auditory beats and brainwave entrainment.
Systematic reviews suggest music listening may improve subjective sleep quality and reduce stress or anxiety in some settings.
That supports designing thoughtfully. It does not prove that one Dastgah, instrument or frequency produces a guaranteed clinical result.
Delta, theta, alpha, beta and gamma describe frequency bands observed in brain activity. Listening to a “4 Hz” track does not simply place every brain into a precise state.
Use a comfortable volume. Stop if a track feels activating or uncomfortable. Music should not replace care from a qualified professional.
