According to God's design, believers are built up in Christ as their voices are lifted in praise. Worship is for His glory and our edification. First, Paul seems to assume significant variety and freedom in the expressions of worship. And of course, what edifies one may or may not edify another in the same way. Sermons are a great example of this truth.
Music can bring similar responses.
As Christians, we are not all moved, blessed, or edified in the same manner. Christian experience makes it abundantly clear that God works through a variety of media for His own purposes. This insight should encourage in us an openness to difference of expression in worship as long as those expressions remain within Scriptural guidelines. Second, in the midst of the diversity, a loving attitude smoothes a lot of feelings. Paul states this principle unequivocally in chapter 13.
