The band returned on Monday morning to play at the Bataclan in front of officials and mourners.

Mr. Macron, who usually embraces an opportunity to give a speech, said nothing publicly during the services, opting instead to share only his private condolences with the families of those who died and had come to pay their respects.

Despite television coverage of the ceremonies, some felt that too few Parisians took part in the observances. Although 200 people gathered close to the Bataclan to watch the ceremony, at the other sites, fewer people came.

But while the sharpest memories of the attacks may be receding for some, much daily life in Paris remains marked by reminders of the threat of terrorism.

Many of the attackers had traveled to Syria or Iraq before returning to France, where they and others presented an essentially homegrown security threat, however manipulated or inspired from abroad.
