World Sound Healing Day is observed worldwide every February 14. Established in 2003 by Jonathan Goodman, a Grammy-nominated musician and spiritual teacher, the day aims to harness the healing power of sound to send a sonic valentine to Mother Earth. Participants create healing sounds filled with love and compassion, which can include vocalizations like "om," musical instruments, or even silent intentions. Early celebrations focused on intoning the sound “aj,” but now any sound with healing intent is encouraged. The event attracts a diverse group of participants, including Grammy-winning musicians, spiritual teachers, and peace activists. Individuals can join organized events, learn about sound healing, share meditation playlists, or promote the holiday on social media using the hashtag #WorldSoundHealingDay.
