What is the meaning of 'dal segno' (D.S.)?

The term 'dal segno', often abbreviated as D.S., is an Italian phrase that translates to "from the sign." In music notation, it instructs performers to go back to a specific sign (𝄋) in the score and repeat the music from that point onward. This directive is essential for understanding how to navigate complex musical sections without having to write out lengthy repeats, thereby making the performance more efficient.

The other options do not accurately convey the specific instruction given by 'dal segno'. For instance, 'gradually getting louder' refers to the Italian term 'crescendo', while 'gradually getting quieter' corresponds to 'diminuendo' or 'decrescendo'. The expression 'with determination' does not relate to 'dal segno' in the context of music notation. Thus, the correct interpretation of 'dal segno' as "repeat from the sign" highlights its crucial role in performance practice.
