Consider these points from Dan Lucarini, former Contemporary Christian Worship leader:

“…I do not trust the argument that all music is or can be good, because of the biblical record. The first musical reference in the entire Bible is not in Psalms or Chronicles, as many believe. It is not in the stories of David or the song of Moses. The first mention of music is found very early in Genesis 4:21, where we are introduced to Jubal, the father of all musicians: ‘He was the father of all those who play the harp and flute.’ Our modern band and orchestra instruments can probably be traced to the handiwork of Jubal and his descendants. Furthermore, the first musician named in the Bible was a direct descendant of Cain, whom God had judged so severely, because he used his own personal references in worship! Ponder that for a moment.

God told Cain that his personal style of worship was unacceptable, because it violated the specific rules given by God. Cain was infuriated with this rejection and extremely jealous that God accepted  his brother, Abel’s, worship. Cain murdered Abel and was banished from the presence of the Lord and His family.Cain’s descendants continued to disobey God. They were so wicked that when they intermarried with the line of Seth, God decided to destroy them with the Flood. This was the heritage and environment of Jubal…

I also recommend a diligent study of 1 Chronicles 15 and 16 where David organized the musical structure of temple worship. This will help us to understand how a fallible man can become acceptable to  God as a music minister before Him, trusted to choose the music and the instruments wisely.”
