The Latin root CAN- and its longer form CANT- are widely used in Latin words and in English derivatives.

CANTATE:
A famous Bach cantata uses the lyrics, "Cantate Domino canticum novum" -- "Sing a new song to the Lord" (cantate="sing!" [command form]; domino="to-the-lord"; canticum="a song"; novum="new").

CANTATA:
The word "cantata" itself means "a sung piece" in Latin.

CANT:
When people intone the same slogans or repeat the same tired proganda without end, we eventually become weary of their "cant" -- a word build of just the Latin root alone.

CHANT/ENCHANT:
Ancient witches were said to "sing" their spells, and monks "sang" parts of their liturgies, from which we have the variant (via French) "chant."

CHANSON:
The French word "chanson" is a direct, live modern version (or descendant, if you will) of the later Latin "cantio [cantionem]", meaning "song." (French is one important modern daughter-language of Latin.)

CARMEN:
The word "carmen" means "song" or "poem" in Latin. It originally comes from the CAN- root with the abstract Latin ending "-men" suffix, but very early in the history of the language it was altered to CAR-men, apparently to avoid all those N and M sounds.

CHARM:
Again the Latin word "carmen" has evolved into French "charme", giving us the English "charm," originally again one of those "sung" spells from magicians and witches.

And there are many more!
