Cantata for Easter Sunday
Bach composed this grand cantata for Easter Sunday 1715 in Weimar. He performed the cantata at least for two more times in Leipzig. There is one interesting detail in the instrumentation. In many of his pre-Leipzig cantatas, you find a small third gap between the woodwind players and the rest of the orchestra. Actually the strings performed in a’ around 465Hz (so called “Chorton”) and the woodwind players played on the lower french a’=392-400hz (so called “tiefer Kammerton”). It happens that in this time many woodwind players actually were french musicians, who came to the german courts and brought their lower pitched instruments with them.
The score contains the 8th aria for soprano, oboe and strings. I added the oboe part in the lower Kammerton.
