417 Hz is the second note of the original Solfeggio scale, corresponding to the syllable "Re" in the hymn to John the Baptist. It is called the "Resonating Frequency" for its association with facilitating change — clearing away negative energy and creating the conditions for positive transformation.

In sound therapy, 417 Hz is used at moments of transition. It is the frequency of new beginnings — moving house, starting a new job, ending a relationship, or any situation where old energy needs to be cleared before fresh energy can take its place. Practitioners believe it helps dissolve the energetic residue of past traumas and negative experiences that can linger in both the body and the environment.

Linked to the sacral chakra (Svadhisthana), 417 Hz is associated with creativity, emotional fluidity, and the ability to adapt to change. Many people use it when they feel stuck or when circumstances feel stale and in need of renewal.
