Chasidim and men of great actions danced before the cohanim with burning torches in their hands. They said words of song and praises. The leviim had harps, lyres, cymbals, trumpets and many instruments.

There were 15 steps going down between Ezras Yisrael and Ezras Nashim which was the same amount of shir hamaalos [songs of going up] that are in sefer Tehillim. On these steps the leviim stood to sing and play instruments. Two cohanim stood by the Upper Gate with two trumpets and the crier called out blow Tekia Teruah Tekia [____ _ _ _ _____].

They walked to the 10^th step and they blew Tekia Teruah Tekia [____ _ _ _ _____]. They reached the floor and again they blew Tekia Teruah Tekia [____ _ _ _ _____]. They kept blowing until they got to the Eastern Gate. When they reached it they turned around and said, ‘Our fathers that were in this place had their backsides to the Heichel and their faces to the east as they worshipped avoda zora. They bowed to the east. However, our eyes are turned to you.’ R’ Yehuda says they also said, ‘And to Hashem our eyes.’

Every day there were at least 7 sets of three blasts, Tekia Teruah Tekia. One set to open the gates in the morning. Three sets for the tamid of the morning. Three sets for the tamid of the evening.
