In the Latin Church the pipe organ is to be held in high esteem, for it is the traditional musical instrument which adds a wonderful splendor to the Church’s ceremonies and powerfully lifts up (the human) mind to God and to higher things.
Note that SC praises the pipe organ. I’ve not always been so lucky to have one in the parish. In one assignment, the priest did have an organ find from the church-building campaign, but when he saw he could get away without one, he shuttled the money elsewhere.
But other instruments also may be admitted for use in divine worship, with the knowledge and consent of the competent territorial authority, as laid down in Art. 22, 52, 37, and 40. This may be done, however, only on condition that the instruments are suitable, or can be made suitable, for sacred use, accord with the dignity of the temple, and truly contribute to the edification of the faithful.
Other instruments, taken in an ensemble, can duplicate the properties of the organ. There are some significant advantages, communally and spiritually, in having an ensemble of instruments lead the singing. There are technical demands that must be met for a group to match the songleading skill of a good organist. But I’ve always found it to be worth the effort.
