“Selo yevoish hamaayan velo yikatzetz ha’ilan — May the spring not dry out and the tree not be cut down.” These words — from the will of the Chasam Sofer ztz”l, a prayer that his descendants should never cease to prosper on the true path — are familiar to the thousands of descendants throughout the world who treasure their lineage as one of their dearest assets. Now a new CD, compiled by Khal Michtav Sofer of Lakewood, expresses the musical side of the holy traditions of the Chasam Sofer dynasty, including, as a finale, a niggun for these oft-quoted words.
