In music notation, dal segno (UK: /dæl ˈsɛnjoʊ/, US: /dɑːl ˈseɪnjoʊ/, Italian: [dal ˈseɲɲo]), often abbreviated as D.S., is used as a navigation marker. Defined as "from the sign" in Italian, 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.[1]
Two common variants:
The Italian term 'dal segno' literally means 'from the sign.' In most music you will see either D.S. al Fine (which means 'go back to the 𝄋 sign and play the music again until you come to the bar marked Fine, then stop') or D.S. al Coda (which means 'go back to the 𝄋 sign and play the music again until you come to the bar marked To Coda, then jump to the coda'). ...You may also see simply...D.S. 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).[2]
Al segno indicates that the player should go to the sign. Da capo al segno (D.C. al Segno), "From the beginning to the sign (𝄋)."[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).
