221.23 Hz is the frequency of Venus, the brightest object in our sky after the Sun and Moon. Venus has been the planet of love, beauty, and harmony since the earliest civilisations — the Greeks called it Aphrodite, the Sumerians knew it as Inanna, and it appears in the mythologies of every culture that looked up at the evening sky.

In sound healing, Venus frequency is used to open the heart, promote self-love, and cultivate appreciation for beauty in all its forms. It is associated with relationships, sensuality, aesthetic pleasure, and the ability to receive — not just give — love and kindness.

The tone has a quality that many listeners describe as warm and inviting. It sits in a sweet spot of the frequency range that feels neither too low nor too high — balanced and harmonious, reflecting the planet's astrological character. It is often used in heart chakra meditations and relationship healing work.
