"Personally I think it'd be more prevalent in areas where there are a lot of churches that don't allow music in the service, but that's just speculation." I think you've got it right there -- Primitive and Old Regular Baptists are down on musical instruments. Below is their rationale, but I've long held a suspicious that the prohibition had more to do with the fact that somebody who plays fiddle, banjo etc. is more likely to skip their farm chores...

The Scriptural Record

The following list includes every reference to the type of music which the early New Testament church used in worship to God. An examination of these Scriptures make plain the kind of music which God designed for His church.

1) And when they had sung an hymn, they went out into the Mt. of Olives - Matt 26:30; Mark 14:26.

2) And at midnight Paul and Silas prayed, and sang praises unto God - Acts 16:25.

3) For this cause I will confess to thee among the Gentiles, and sing unto thy name - Romans 15:9.

4) I will sing with the spirit, and I will sing with the understanding also - 1Cor 14:15.

5) Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord - Eph 5:19.

6) Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord - Col 3:16.

7) In the midst of the church will I sing praise unto thee - Heb 2:12.

8) Is any among you afflicted? let him pray. Is any merry? let him sing psalms - James 5:13.

Conclusions Drawn from Consideration of the Scriptures

Where in the inspired record of the New Testament church is there found a single reference authorizing instrumental music in worship? Nowhere! The most careful, meticulous investigation of the New Testament will not produce a single word in favor of this practice. One may search the New Testament in vain for either command, example, or inference for the use of musical instruments in worship service.

The Lord's church is a New Testament institution, and the New Testament tells the items of worship the Lord put in it. It has been shown that the New testament is silent concerninginstrumental music in the worship. It is evident that those who do use musical instruments in the worship service do without Scriptural authority.

When Christ ascended back into heaven, the Holy Spirit undertook to guide the disciples of Christ in their activities of worship (John 16:13). The Spirit guided the apostles into singing and into exhorting others to sing, but the Spirit never guided the apostles into performing upon instruments in worship or into exhorting others to do so.
