I love the guitar and the piano, and I play both. I am a trained musician with a master’s degree in music. As part of my master’s degree, I did a study of the writings of the Vatican (papal, conciliar, and curial) about music. The answer to this whole discussion, as has been pointed out several times, is not a matter of preference. The guitar and the piano were both forbidden in the mass. Nothing ever changed that. The fact that statutes were ignored does not make them invalid or no longer binding. I shall quote here from a 1903 motu proprio by Pope St. Pius X (and please do not misunderstand my invoking his venerable name to indicate any association with the fringe group who uses; I am in full acceptance of the Second Vatican Council and the Mass of Paul VI, when it is said according to the rubrics). The document is entitled “Tra le Sollecitudini” and it says:
“2. Sacred music should consequently possess, in the highest degree, the qualities proper to the liturgy, and in particular sanctity and goodness of form, which will spontaneously produce the final quality of universality. **It must be holy, and must, therefore, exclude all profanity not only in itself, but in the manner in which it is presented by those who execute it.**It must be true art, for otherwise it will be impossible for it to exercise on the minds of those who listen to it that efficacy which the Church aims at obtaining in admitting into her liturgy the art of musical sounds.”
It continues, later
“VI. Organ and instruments
15. Although the music proper to the Church is purely vocal music, music with the accompaniment of the organ is also permitted. In some special cases, within due limits and with proper safeguards, other instruments may be allowed, but never without the special permission of the Ordinary, according to prescriptions of the Caeremoniale Episcoporum. 16. As the singing should always have the principal place, the organ or other instruments should merely sustain and never oppress it…
18. The sound of the organ as an accompaniment to the chant in preludes, interludes, and the like must be not only governed by the special nature of the instrument, but must participate in all the qualities proper to sacred music as above enumerated. **19. The employment of the piano is forbidden in church, as is also that of noisy or frivolous instruments such as drums, cymbals, bells and the like.**20. It is strictly forbidden to have bands play in church, and only in special cases with the consent of the Ordinary will it be permissible to admit wind instruments, limited in number, judiciously used, and proportioned to the size of the place provided the composition and accompaniment be written in grave and suitable style, and conform in all respects to that proper to the organ…”
Now certainly the document predates the council, but
Musicam Sacram (quoted earlier in the thread and issued under the reign of the same Pope Paul VI who promulgated the mass) clearly reiterates the same points. The missives of the motu proprio were never condemned or altered by subsequent popes, but were consistently upheld, so I gather that they must be in effect to this day.
The piano and percussion instruments are forbidden
by name. Neither I nor anyone else has to debate whether or not they are allowed; they are expressly forbidden. I have heard the piano and other forms of percussion throughout the mass far too many times to count, but they are not now, nor were they allowed, no matter how much you like them or hate them.
As for the guitar, it is always a harder matter. St. Pius X prohibits “profanity not only in itself, but in the manner in which it is presented by those who execute it.” The Sacred Congregation for Divine Worship writes in
Musicam Sacram: “However, those instruments which are, by common opinion and use, suitable for secular music only, are to be altogether prohibited from every liturgical celebration and from popular devotions.” Both of these send the same message, as far as I read them: anything that belongs to secular music–and not that is not the same as popular music; the banjo, the accordion, and the tin whistle all seem equally as applicable–is forbidden at the mass. That begs the question: is the guitar suitable for “secular music only”? And, when you search your heads, you’ll be hard pressed to find examples of sacred guitar music. Sure, there was “Stille Nacht” (“Silent Night”), but that was a unique circumstance. What else is there? The guitar was created for folk music, adopted by classical music for use in the courts of Western Europe, used for a lot of dance music of many genres, none of which was sacred, and then brought into Jazz and then the other American Popular music styles.
Inside your hearts, I’m sure you all know the guitar is a secular instrument. I don’t really have to make the argument. It’s not about whether or not you like the guitar, piano, etc. It’s not about how much you love the organ. The question really shouldn’t even be “What do you think about guitars during mass.” We are Catholic, and we are obedient. They’re just not supposed to be there, no matter how good hearted and talented the musicians are.
Now if you’d like to send them to me, I’d be happy to teach them all to chant.
