Rondo is a musical structure. You’ve heard one before.
Think of your favorite pop song. Let’s call the Chorus “A”. Each verse of the song will have a different letter, B, C, D, and so on.
A rondo works like this:
A - Chorus 
B - Verse 1 
A - Chorus
C - Verse 2 
A - Chorus 
D - Verse 3
Life is like a rondo.
In between different verses there are main themes, “A”, that return.
The trick is to make each return of “A” better than the last.
