Dal segno

appears in sheet music and instructs a musician to repeat a passage starting from the sign shown at right, sometimes called the segno in English.

[1] Two common variants: The Italian term 'dal segno' literally means 'from the sign.'

in the final bar of a score, which means to repeat from...the 𝄋 sign...then stop at the end.

In music, these instructions always appear at the end of the bar from which you have to jump back (either to the 𝄋 sign or to the start of the piece).

"[3] In operas of the 18th century, dal segno arias were a common alternative to da capo arias which began with an opening ritornello, which was then omitted in the repeat (the sign being placed after the ritornello).
