Sasaki Roshi put emphasis on chanting. The common practice at the Zen Centers was chanting after tea in early morning, which took approximately 35 minutes, and would happen even if Zazen was not scheduled. Chanting accompanied the meals, in the afternoon during Dai Sesshin, and with closing in the evening.
Posted here is chant book used in morning. The content is syllables which are English phoneticized mostly archaic Sino- Japanese and Sanskrit.
The chanting is led by Densu, an officer of the Zen Center, who starts the chants, leads the chants, rings two different size gongs, and does solo chanting called Ekos. The Sho Den, or assistant, keeps time with a makugyo, a type of drum.
There are audio recordings of Sasaki Roshi demonstrating selections of chants. He did not commonly chant with the group.
