Ezekiel 28:13 of the KJV and NKJV seems to hint that Satan was involved with music in Heaven. The NKJV says, “The workmanship of your timbrels and pipes was prepared for you on the day you were created,” although the exact meaning of this difficult Hebrew text is uncertain. There may have been such instruments in heaven, but there is no evidence outside this verse to verify it. Revelation 5:8 and 15:2 refer to harps, but not to timbrels or pipes.
The two Scripture passages that describe Satan before he fell are Ezekiel 28:12-19 and Isaiah 14:12-15. Satan was the “anointed cherub” (Ezekiel 28:14). He was adorned with every precious jewel imaginable (Ezekiel 28:13). He was “the model of perfection, full of wisdom and perfect in beauty” (Ezekiel 28:12b). Likely he was the highest of all angels. He was persuasive enough to convince one-third of the angels to join him in his rebellion (Revelation 12:4). Even after his fall from heaven, not even Michael the archangel dared to stand up to him without the Lord’s help (Jude 9). Satan fell because of pride. He did not like being “second best.” He wanted to be God: “You said in your heart, ‘I will ascend to heaven; I will raise my throne above the stars of God; I will sit enthroned on the mount of assembly, on the utmost heights of the sacred mountain’” (Isaiah 14:13).
Was Satan the head musician? This cannot be answered definitively. Scripture does not say enough about what his duties were in heaven. Considering the fact that the angels constantly worship God (Isaiah 6:3; Revelation 4:8), it is possible that Satan led that worship. One thing is sure: for Satan to rebel despite having such an exalted position and close relationship with God, the devil is surely due his eternal destiny (Revelation 20:10).
