Crystal singing bowls at 432Hz give creative minds a long, unhurried space to rest and reflect after a day of making. Crystal singing bowls ring softly and fade into one another in a slow, spacious sound bath tuned to 432Hz, running for four and a half hours. Press play as you settle into bed with the volume just above a whisper. Let it carry you to sleep, or keep it low while you write, sketch or journal. (A relaxation aid, not a medical treatment.)
