A New Song and the Sealed Book
Only the 4 beasts and 24 elders can sing the new song while the book is sealed with seven seals.
And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals. And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof? And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon. And I wept much, because no man was found worthy to open and to read the book, neither to look thereon. And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Judah, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof. And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth. And he came and took the book out of the right hand of him that sat upon the throne. And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odors, which are the prayers of saints. And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation; (Rev. 5:1-9)
After the book is unsealed, the 144,000 are able to learn the song.
And I looked, and, lo, a Lamb stood on the mount Zion, and with him a hundred forty and four thousand, having his Father’s name written in their foreheads. And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps: And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth. (Rev. 14:1-3)
The 4 beasts and 24 elders sing the new song in chapter 5 while the book is sealed.
In chapter 14 the 144,000 have learned the song and sing it before the beasts and elders who had sung the song in chapter 5.
The 144,000 learn the song from the beasts and elders, who didn't need to be taught the song.
As the 144,000 are taught by the ones who understand, it is as if the seals come off the book for them.
The book being sealed is what keeps the new song from being learned. As the seals are removed from the book, coming to understanding is great tribulation. The things that happen while the seals are removed is a symbolic message, not physical events. Revelation, the Apocolypse, the unveiling of Jesus Christ, is a wholly symbolic book. If you take literally a writing that was meant to be symbolic, then you will be in error and won't understand.
That the book (Scriptures) being sealed means that it can't be understood can be seen by comparing the sealed book in Ezekiel, Isaiah, Daniel, and Revelation.
Daniel says that it is sealed until the time of the end, and then the wise will understand.
Ezekiel makes it clear that the sealed book of Rev. 5 and the open book of Rev. 10 are the same book. In Revelation, the seals come off so it can be understood.
Isaiah makes it clear that the sealed book is Scriptures, says how it became sealed, and that it will become understood.
Revelation has the keys to understanding Scriptures (the unveiling). Some figurative terms are defined, and some spiritual themes can be deduced. These definitions and themes can be applied throught Scriptures to help in understanding.
