I’ve noticed what you have: that a “low” Mass seems more reflective. So are people coming because it is shorter, or because it is more prayerful?
Well, I guess people (the majority of Catholics now ) would go to a Low Holy Mass or its’ equivalent in the Novus Ordo for the sake of time — because it is shorter. But, its’ prayerful sense might also enlighten their faith. Heres what I would do: I would have a
Missa Lecta or Holy Mass with no music but then, (you, being the priest) could sing things; maybe
you sing or in better terms chant the first and second reading, the psalm, the gospel, the collect, Eucharistic Prayer (maybe even Eucharistic Prayer #1

), post-communion prayer, etc. That is what would really would help me become prayerful. It doesn’t add that much time and is still beautiful. Maybe even add in an organ accompaniment. You might even consider adding a great homily about receiving Holy Communion in a state of grace and well disposed, etc., or about confession, or the reality of Hell, or something else to catechize the average uninformed Catholic sitting in your Church pew. I really think that is the best of both worlds: you get singing while you maintain a beautiful, reverent liturgy. Thanks Father for dedicating your life to Christ and His Church!
P.S. You might even add in some *ad orientem * Holy Masses so that the congregation isn’t watching your every move.

<---- The top part was serious! But really, you should consider
ad orientem! Thanks!
