In music notation, Dal segno (/ˌdæl ˈseɪnjoʊ/ or /ˈsɛɡnoʊ/; Italian pronunciation: [dal ˈseɲɲo]), often abbreviated D.S., is used as a navigation marker. From Italian for "from the sign," D.S. 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.
Two common variants:
Al segno indicates that the player should go to the sign.
In operas of the 18th century, da 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).
The Segno sign is encoded in the Musical Symbols block of Unicode as U+1D10B MUSICAL SYMBOL SEGNO: ...
