Tuned to A 432 hz - My bowed Psaltery Psolo of “Gwalchmai“ by John David Jones (1827-1870) used as the setting for “King of Glory, King of Peace“ by George Herbert (1593-1632) and many other Hymns.. Some people prefer this tuning, look into “Cymatics“ as too why: Please visit my “Bowed Psaltery Tuned A 432hz“ playlist here on YouTube
