Just a few blocks away from where I live, I heard a group singing Pasyon. The younger generation may not be aware of what Pasyon or Pabasa is all about. It is the Lenten tradition of singing the life, passion, death and resurrection of Jesus Christ.
The Pasyon singers usually use microphones and speakers to amplify their voices. Modern chanters use devices to enhance the quality of their voices. For me, whatever device they use to sing Pasyon is acceptable as long as they clearly convey the meaning of what they sing that is the life and passion of Christ.
