I use to do 2 on Saturdays and 5 on Saundays at a large Dominican church and at my last position with a school, I did 10 during the mornings Mondays-Fridays and 3 on the weekends.
Our Parish has 1 on Saturday evening, 4 Sunday morning (all English - 3 time slots, 1 Mass in the Parish Hall), and 1 Sunday afternoon (TLM). I generally play only the PH and TLM, but am available to sub the entire weekend.
when i was in cincinnati i had one on saturday (plus usually one or 2 weddings and or funerals) and sunday was 7:30. 9:00 (childrens choir), 10:30 (adult choir) 12:00 (folk group) then travel 80 miles to lexington for a 2:30 rehearsal for 4:00 high Mass with gregorian propers polyphonic ordinary and motets followed by the 80 miles back to cincy.
now in florida i have school mass on fridays one mass on saturday, 3 on sunday and the obligatory nap on sunday afternoon.
An Vigil Mass on Saturday, with cantor. and two on Sunday with Choirs and rehearsals 1/2 hour before. There are also extra services in the afternoons on the 6 Sundays in Lent. Also daily Mass in the evening Mon-Fri, and a Mass on Sat Morning, with cantor.
And I am pleased to report the a goodly amount of the congregation sing at all of the Masses - standard hymns and Gregorian Chant! (Except for the Saturday vigil; It seems that most of the attendees at that Mass are the ones that always attended the earliest clickety-clack Low Mass - without even organ music! - during the 'Good Old Days'. Well, you can't have your cake and eat it too!)
