Out of consideration that the Gothic cathedral is still being rebuilt, the choir members wear helmets and boiler suits, and there is no audience.
The concert was recorded at the cathedral earlier this month and will be shown on French television before midnight on Thursday.
The choir played classical works by composers Mozart and Schubert, but the repertoire was more relaxed, including “Golden Bell”.
The cellist Gautier Capucon said: “It’s very moving.” Together with the organist, he provided musical accompaniment to the choir.
In an interview with French TV station French TV, he said: “This is the first time we have returned to Notre Dame de Paris since the fire. This is an emotional moment.”
The cathedral is a landmark of Gothic architecture dating back to the 13th century and is a major tourist attraction, which caught fire on April 15, 2019. The fire destroyed the spire and roof.
French President Emmanuel Macron promised to restore the cathedral within five years.
But so far, most of the work on the site has focused on making the building safe, including removing toxic lead from the roof and spires that melted in the fire.
At the same time, Notre Dame de Paris was closed to the public and the masses were cancelled.
