* The specific church or parish: Each church has its own team of cantors, music ministers, or other individuals who lead the music for Mass.
* The day of the week: Some churches may have different cantors for different days of the week.
* The specific Mass schedule: Some churches have a specific person assigned to lead the music for a particular Mass time.
Therefore, you need to specify the church and time of the Mass to know who the cantor is.
You could try contacting the church office or checking their website for information on their music ministry.
