BTW - Ba'al Tefilah Workshop: Help! I Got the Wrong Nusach! 😳 (Nail those Transitions)

Sure, you know Nusach. But, what do you do when slip into the wrong Nusach? Suppose it's Shabbos, but you mistakenly ended Kedushah with the Rosh Chodesh/Shalosh Regalim tune? How do you recover? How do you ensure that you won't make those mistakes? Are you prepared to transition in and out of any Nusach, whether Shabbos, Shalosh Regalim, or Yomim Nora'im?
