The purpose of what we do in the Church is invite all to come to Christ and be perfected in Him.

• So, music should help with that, and not ever be a distraction.
• If it is badly done -- choppy, wrong notes, volume, choice of music, style etc -- it doesn't help, and can distract or distress worshippers.
• But, if it is beautiful and peaceful, using the right music, it can share gospel principles that lead to peace in this life & eternal life in the world to come.
• It can also help the Church meetings in the chapel be an elevating, good experience -- again, to invite the Spirit and lead us all to Christ.
• Our own spiritual development by gospel study and obedience helps refine us for this purpose.
• I think there is no substitute for praying before doing anything. (See verses in 2 Ne 30 or 31 about praying so our performance is consecrated for gain. Etc.)
