Modern musical instruments in Catholic church service

I joined this group specially to answer this question.

I am not a Catholic (or a deist of any kind) but as a musician in a local brass band I often play in church, for all kinds of services. This is in South Germany, a very Catholic area.

We play all usual brass band instruments, and for modern pieces we will even add a drum set (though the first time we did that that it did set the grandmas whispering).

No-one has ever complained, and it must be approved, because we have a special book of hymns set for brass band, issued by the diocese.

Organ is the most common instrument in Catholic churches (almost all, even the smaller ones, got one): in general, it's the only instrument allowed BUT... the local bishop could allow other instruments.

Generally, classic guitars are allowed. My Bishop allows basses, bongos and flutes too (but every one knows that he doesn't really like bongos, so no one use them). My bishop also listed songs that are allowed during celebrations-

//Does the Catholic Church allow latest musical instruments(guitars, drum set, piano etc.) to be played while worshiping in the church?//

No. Modern musical instruments are not allowed unless permitted by the local bishop. Guitars and Drums are explicitly forbidden for Liturgical use. I am not a musical student so I don't know the difference between a Organ, Keyboard and a Piano. But an Organ is the standard liturgical instrument. (Any instrument that can replicate organ's sound in a similar way will be permitted)

Liturgical services are not parties, but are celebrations of the Church. Center of the liturgy is Christ but these instruments put the player in the center. And that is the main reason why these instruments are banned.

• 62 The pipe organ is to be held in high esteem in the Latin Church,.
• 63 ... Any musical instrument permitted in divine worship should be used in such a way that it meets the needs of the liturgical elebration, and is in the interests both of the beauty of worship and the edification of the faithful.
• 64 The use of musical instruments to accompany the singing can act as a support to the voices, render participation easier, and achieve a deeper union in the assembly. However, their sound should not so overwhelm the voices that it is difficult to make out the text; and when some part is proclaimed aloud by the priest or a minister by virtue of his role, they should be silent.
• 66 The playing of these same instruments as solos is not permitted in Advent, Lent, during the Sacred Triduum and in the Offices and Masses of the Dead. From MUSICAM SACRAM - Instruction on Music In The Liturgy

//Once I attended a Catholic church. ... There was no music, no musical instruments. I wonder if this is how they worship always.//

No it is not without music always. Music is an integral part of liturgy. And musical instruments have aided in the liturgy for ages. The problem is with the modern music and instruments. For instance solemnities like Easter and Christmas people are strongly advised/urged to celebrate mass with proper music and choir. They both exercises its own liturgical function among the faithful by law.

I can't speak for countries out side of the U. S., but here in the States any type of musical instrument is permitted as long as:

A. They are approved by the right authority.

B. They are played in a manner that is edifying.

Sacrosanctum Concilium 120:

"The use of other instruments may also be admitted in divine worship, given the decision and consent of the competent territorial authority, provided that the instruments are suitable for sacred use, or can be adapted to it, that they are in keeping with the dignity of the temple, and truly contribute to the edification of the faithful."

I, myself, have been actively involved in liturgical services for 20 years. I have either personally played or attended many Masses in multiple states. The majority of the liturgical services I have attended have been in Georgia, Alabama, Tennessee, Florida, and Louisiana.

About 80% of these Masses included (but is not limited to) the following instruments for the various elements of the Mass (responsorial Psalms, etc.):

1. Acoustic/electric guitar

2. Percussive drum sets.

3. Other types of percussion instruments including bongos, xylophones, tambourines, etc.

4. Acoustic/electric/amplified guitar.

5. All instruments included in an orchestra.

6. Keyboards/pianos

I have participated in a youth retreat held every year throughout the U. S. that incorparates very intense praise and worship music in order to appeal to teenagers.

The dramatic change of liturgical music in the U. S. is one of the major topics of debate.

We recently hired a new music director who has fired up this debate in our parish. As a result I did some research:

Musicam Sacram section VI, 63 states that any instruments can be approved if

1. the bishop is okay with it,
2. the instrument can add to the sanctity of the music, not bringing to mind secular subjects, and
3. it is commonly accepted.

I read this to mean the local bishop has final say in each region, in the absence of direct orders from the Vatican. This allows the mass to best serve each locale, even under a larger global umbrella of authority.
