Do you know how powerful singing is and why God created it? Deuteronomy 29-31

Deuteronomy 31:19
“Now therefore, write this song for yourselves, and teach it to the sons of Israel; put it on their lips, so that this song may be a witness for Me against the sons of Israel.

In the book of Deuteronomy Moses is given the "second" edition of the Law.   The first edition was given to those who rebelled against God and who did not obey Him.  They were allowed to die in the wilderness over the past 40 years and a new generation arose who did not know the complete Law.  So, Deuteronomy (which means, "Second giving of the Law") was written.   Yet, even though this new generation was witness to the death of their parents for that rebellion toward God's Word, so, too, Moses knew they would be rebellious.   Chapters 29-31 are typically knows as the blessings and the curses.   The nation is given a choice to either obey God and be blessed or disobey God and be curse.   Moses knew the hearts of the people, however, that they were constantly rebellious.  In the above verse we see Moses telling the nation that he is going to put the warnings to obey God in the genre of a song.   Moses knew the power of music and musical lyrics.   God made many to enjoy the sound of music.   It is amazing how many young people don't know simply historical facts (or, can't remember them for a test), yet they can sing, without mistake or error, the words of the latest popular song.     Words set to music are much easier to memorize and learn than words without music.   It is probably more real to believe that Moses' song was more of a poem than an urban rap.   Songs in the Jewish culture were much different than songs in the Western culture, today.  However, the interesting thing about songs, especially set to a notable tune, is that they are easily recognizable.  This devotional is being written in late December while I'm in a retail coffee shop.   The music on the overhead speakers is "Santa is Coming to Town."  When the music is played I can quote every word of the song, even though I only hear it once a year.   Yet, the four or five verses I have been trying to memorize since September still fail me.   Music allows truths to be remembered and to be be retained.   God placed the ability for songs to make a difference in our lives, in our hearts.    Moses knew that and gives the nation the best message via song.  The song is found in chapter 32, but the outline of the song is found in chapters 29-31.   The truth Moses wanted to tell them is that if we believe God and obey Him, blessings will follow.  If we fail to believe God and disobey Him, curses will follow.  A simply tune that needs to be song over and over and over, again.
