Trumpets and triangles

Mister Rogers attaches a triangle to his sculpture. He pretends that a paper towel and a toilet paper roll are horns and plays music on them. Frank Ostrowski, a trumpet player, knocks on the door, asking directions to the castle. He plays for Mister Rogers and explains how the trumpet works. In the Neighborhood of Make-Believe, King Friday tells Lady Aberlin how to play the triangle to accompany the trumpet players. Sara Saturday is arriving today. Lady Aberlin plays for X and Henrietta. They try the triangle. X has to be reminded to play gently. Robert Troll is helping Sara Saturday move to the Neighborhood of Make-Believe. Accompanied by trumpet and triangle, Sara Saturday arrives in a sedan chair carried by Officer Clemmons. Back with Mister Rogers, he plays a record of the Purcell trumpet voluntary.
