Imagine reading a book where a tiny symbol suddenly teleports you back three chapters to read them a second time. In sheet music, that happens all the time β€” and it saves composers from rewriting the same measures over and over!
To navigate a piece without getting lost, you just need to know how to read the composer's musical road signs.

The Repeat Sign

A repeat sign is a double bar line paired with two vertical dots that commands you to play a section of music again.
When you reach dots pointing backward to the left, you jump back to the matching forward-facing dots β€” or all the way to the start if no opening dots exist.
What happens when a song repeats almost everything, but needs a brand-new closing note at the very end?

First and Second Endings

Composers use first and second endings, marked by numbered horizontal brackets over the measures, to switch up the finish.
You play measure 1 through the 1st ending, hit the repeat dots to loop back, and on the second pass, you skip bracket 1 entirely to land straight in the 2nd ending.
A common mistake is playing ending 1 a second time right before ending 2. Remember: the moment you repeat, bracket 1 is skipped forever!
