Here, in the opinion of the author, are some principles to observe with respect to the volume level of the voices and instruments of the PT (Praise Team).
1. A lot of noise is not automatically the sign or indication that something spiritual is happening. There can be loud sound coming from the instruments of the PT and from the voices of the singers, but this is not an indication that anything spiritual is happening in the heart.
2. Nevertheless, the loud volume of the instruments and of the singers can be a sign that something spiritual is happening. It may arise from the enthusiasm that the worshipers feel about God and Jesus and about various other spiritual themes. Excitement about something will generally raise the level of volume of voices and instruments. This is not a bad thing!
3. Volume is to some extent governed by the words of the music and by the mood of the worshipers. When enthusiasm is expressed in the words of a song, it is appropriate to express that enthusiasm with voices and instruments. If a song calls for quiet contemplation is would seem appropriate to let the volume express this also. For example, loud music would seem inappropriate for a funeral service. Generally, when the mood of the worshipers is enthusiastic, the volume of the music will rise.
4. On occasion the enthusiasm of the PT will be greater than that of the congregation. It would not seem inappropriate that the volume of the singers would therefore be greater than that of the congregation. In such a situation the enthusiasm of the singers could be contagious for the congregation, and they may catch the enthusiasm also. But this is not the same thing as volume for volume’s sake. The volume is in relationship to the enthusiasm of the PT.
5. Generally, the volume of the Praise Team should not consistently drown out the volume of the congregation (People of God). It becomes discouraging for worshipers when they can not hear themselves or anyone else sing. As the volume of the congregation rises, the volume of the PT may also rise. In other words, there should be some correspondence between the volume of the PT and their instruments, and the volume of the congregation.
6. The reason why worshipers should be able to hear their own voices and those of other worshipers is that one’s own faith can be strengthened when one hears the voices of others lifting up their own voices to the same God. The expression of the faith of others encourages one in his/her own expression of this faith.
7. In summary, volume should not be like the motor of some furnaces. Some furnace motors have only one setting – full blast. In my opinion, praise and worship singing will be more enjoyable when there is some correspondence between the words of the songs, the mood of the congregation and the volume of the voices and instruments of the PT.
