Brother and AI

We asked a generative AI to help writing the slides for an music video. Warning. It came out a bit weird.
The music was written in Mathematica: 

f={1,1,3,3,5,5,1,1,1,1,3,3,5,5,1,1,5,5,6,6,8,8,8,8,5,5,6,6,8,8,8,8,
   8,10,8,6,5,5,1,1,8,10,8,6,5,5,1,1,3,3,-4,-4,1,1,1,1,3,3,-4,-4,1,1,1,1};
A=Map[SoundNote,f];s=Sound[{"Choir",A},{0,16}];
Export["brother.midi",s,"MIDI"]


We tried to modify the lyrics also at first. Here is what the AI fed us 

Dearest Brother Nabla, Dearest Brother Nabla,
In your slumber deep, in your slumber deep,
The echoes of Lagrange, the chimes of formulas,
In the silence of the night, they weave a song so sweet,
Ding, dang, dong, the symphony prolongs,
Ding, dang, dong, resonating strong.


We opted to our own adaptation of the lyrics. 

Brother Nabla, Sister Nabla
Are you asleep, are you asleep
Lagrange bells are ringing
Clairaut bells are singing 
Ding, dang dong. Ding dang dong.
