Having the same address on whois doesn't mean that is your residence.
Agreed. And the same should apply to pianos, and electronic/casio keyboards. The instrument to be used for sacred music is the organ - with the pipe organ (not electronic gizmo)as the instrument of choice.
Such is clearly indicated in the beloved documents of Vatican II.
On your elimination list I would also include, rocks, sticks, percussion instruments in general, anything which uses and amplifier, a whole wealth of bizzare primitive things from tribes of the rain forests of South America; wind chimes, and two hands clapping.
Bongos. Don't forget bongos. Also those shaking, rattling gourd-like things. I can't remember what they are called. All very indigenous people affiliated instruments.
It should be a pipe organ. The Congregation of Sacred Rites specified this a number of times when turning down the requests from the Hammond Organ Company in the late 1930's and through most of the 1940's.
The Congregation of Sacred Rites, however, approved the use of the Hammond Organ @ 1948 if I recall correctly using the "usual excuse" that was employed to sew the seeds for V2 on various and sundry issues: destruction of churches in WW II, lost of male populace, cost of replacement, etc.
This excuse was also used to introduce evening Masses (for the same day) @ 1952, mitigation and lessening of the Eucharistic Fast, and also permitting women in the choir, 12-25-55.
Of course the document never at all addressed Pope Saint Pius X's pronouncement of 11-22-03 that since the choir **AT MASS** substituted for the clergy, it could only be composed of males - the same as for acolytes.
The future Pope Pius X was involved with this issue for over 20 years on various commisions under Pope Leo XIII and as Cardinal Patriarch of Venice in his archdiocese he also banned all women musicians including organists.
Women in the congregation, as were men, were urged to sing, in other liturgical services and devotions such as Vespers, BUT NOT IN THE MASS!!!
P.S. In the preamble of his document of 11-22-03 it is , "actuosa communicatio", actuated communication in uniting oneself with the priest in offering Christ, the Victim, to the Father. It is NOT 'active participation', which commonly appears in the usual intentionally incorrect mistranslations.
This intentional mistranslation of two words in this preamble was used as justification for all that followed in the 20th century.
