What is the difference between D. C. and D. S. in music theory?

Heres the answer

Explanation:

D.C. al Coda tells you to repeat the piece until you reach the coda sign ($) then skip to the next coda sign, and play the coda, a short ending section (literally "tail"). D.S. al Fine means to go back to the dal segno sign and repeat until the point marked Fine.

Hope this helps!

In short, D.C. tells you to repeat a section until you reach a coda sign & then skip to the next coda (typically a short ending) while D.S. tells you to go back to the D.S. sign & repeat until a point marked fine.
