12. Nigun Hisvaadus II
This nigun is often sung before a Chassidic discourse is delivered, setting the mood and opening the hearts of those present. It is a stirring nigun in three sections. It is sung slowly, reflectively, with a contemplative mind and with fullness of heart, expressing introspection and yearning for spiritual elevation.

Hi
What is the difference between this Niggun and track #5 on this album (Niggun L'Shabbos V'Yom Tov)?
They are completely different niggunim. This one is often sung before the recitation of a maamar, and the other one (#5 on this album) is traditionally sung as a prelude to the Alter Rebbe's niggun, Daled Bavos.
(There's a third niggun, titled the Rostover Niggun but also sometimes called "Niggun Hachanah," that is also often sung before the recitation of a maamar, but that is typically reserved for when the Rebbe recites a maamar.)
