There is a bit of a problem with this.
Many professional musicians aren’t too happy when people volunteer to do work that they want to be paid for.
It robs them of their livelihood and cheapens their work.
Truly, I do not tell too many of my musician friends that I am unpaid for playing for Masses. It’s not a wise thing for me to spread around town. Musicians have a lot of solidarity, and musicians’ unions are fiercely protective.
I suppose to some of you, playing for free in Mass is “ministry,” but honestly, if I stop to think about it, I feel like scab labor, working for free because I can afford to, while my musician friends struggle to find work that will earn enough for them to afford their basic needs. So I try not to think about it.
If all of us who volunteered stopped volunteering, it would make things better for our musicians friends. OTOH, as Pilgrim1701 has pointed out several times, there is no requirement for Mass music, and I fear that most parishes would simply say, “Too bad, so sad, no more Mass music for our parish.”
I would be interested in how some of the full-time musicians on this board feel about the issue of unions/solidarity among musicians, and whether or not we who volunteer hurt those who are trying to earn a living. To me as a Catholic, this is a huge issue–making sure that I don’t deliberately prevent others from making an honest living.
Also, we have to consider the issue of “equal pay for equal work.” What makes playing for a Mass different when I play as opposed to when a professional musician plays? I am a very good pianist who plays professionally (gets paid)–but I don’t make a living at it. The JOB of playing is the same, whether I play or someone else plays. Are we paying for the JOB? Or are we evaluating each person who plays and saying, “You’re supporting a family, therefore you get paid. You’re buying a Coach purse, therefore, you won’t get paid.” This doesn’t seem right, when the person buying the Coach purse does the exact same work as the person who is supporting a family.
