"Rejoice, rejoice, up, praise the days!" - What Bach presents here cannot be summed up in criteria of masterful orchestral treatment and skilful text adaptation alone. The music-making of this opening chorus, unleashed by pithy kettledrum beats, directly grips the heart, belly and not least the legs of the listeners before any rational reflection, who want to jump up spontaneously from pews and desk chairs and do not have the slightest chance of escaping the contagious jubilation.
