Music

"Solemn responsibilities rest upon the young. The introduction of music into their homes, instead of inciting to holiness and spirituality, has been the means of diverting their minds from the truth. Frivolous songs and the popular sheet music of the day seem congenial to their taste. The instruments of music have taken time which should have been devoted to prayer.
Music, when not abused, is a great blessing; but when put to a wrong use, it is a terrible curse. It excites, but does not impart that strength and courage which the Christian can find only at the throne of grace while humbly making known his wants and with strong cries and tears pleading for heavenly strength to be fortified against the powerful temptations of the evil one.
Satan is leading the young captive. He is a skillful charmer..."
Testimonies for the Church Vol.1, p.497 E.G.W.

And the priests waited on their offices:

the Levites also with instruments of musick of the LORD,

which David the king had made to praise the LORD,

because his mercy endureth for ever,

when David praised by their ministry;

and the priests sounded trumpets before them, and all Israel stood.

2 Chronicles 7:6
