Theta waves sit at roughly 4 to 8 Hz — slower than relaxed wakefulness, faster than deep sleep. It's the frequency of the hazy, hypnagogic state as you drift off, of REM dreaming, and of deep meditation. People associate theta with creativity, intuition and letting the mind wander productively.
How theta sound is used
A binaural beat around 6 Hz is a common theta choice — played through headphones during meditation, journaling, or a pre-nap wind-down. One study found theta activity developed across the cortex within about ten minutes of listening to a 6 Hz beat, which is part of why theta is a favourite for meditative sessions.

What the evidence says
The brain does appear to partly follow a theta beat, and many meditators find it a helpful anchor. But whether that reliably deepens meditation or boosts creativity is not settled — results are mixed and vary between people. As with all entrainment, it's a reasonable, pleasant thing to try, best treated as a support for a practice rather than a shortcut to one.
Theta is the daydream frequency — lovely under a meditation, modest in the evidence. Use it to support the practice, not replace it.
