Originally, Yizkor was recited only on Yom Kippur. Its primary purpose was to honor the deceased by committing to giving tzedakah [charity] in their memory, on the theory that the good deeds of the survivors elevate the souls of the departed. It also enhanced the chances for personal atonement by doing a deed of loving kindness. Since the Torah reading on the last day of the pilgrimage festivals [the holidays of Sukkot, Passover, and Shavuot] mentions the importance of donations, Yizkor was added to these holiday services as well.

The Four Parts of Yizkor

1. A series of readings and prayers, recited and chanted, that sets the mood for the solemn service.
2. Paragraphs that individuals read silently recalling the deceased. There are paragraphs for a father, mother, husband, wife, son, daughter, other relatives and friends, and Jewish martyrs. During the service, each person reads the appropriate paragraph(s).
3. The memorial prayer for the deceased, the El Male Rahamim [God full of compassion] is chanted. This is essentially the same prayer said at Jewish funerals.
4. A special prayer, Av HaRahamim (Ancestor of Mercies), probably composed as a eulogy for communities destroyed in the Crusades of 1096, is recited by the congregation as a memorial for all Jewish martyrs.
