神葬祭における拝礼は、神棚や神社を拝礼するときと同様に「一揖一拝二拍手一拝」（いちゆういっぱいにはくしゅいっぱい）「二拝二拍手一拝」などで行なうが、葬儀のときの拍手(神道)は火葬場へ送るまでは音を立てずに行う。

The worship manners in Shinsosai are the same as when worshipping kamidana or shrines--you bow a little once, bow once, clap hands twice, and bow once ('Ichiyu-ippai-nihakushu-ippai' style) or you bow twice, clap hands twice, and bow once --, but when clapping hands (Shinto) in funeral rites, you are required to do so without making a sound until the body is brought into a crematorium. - Wikipedia日英京都関連文書対訳コーパス
