curved line connecting 2 more notes different pitches
Tie (music) In music notation, a tie is a curved line connecting the heads of two notes of the same pitch and name, indicating that they are to be played as a single note with a duration equal to the sum of the individual notes' values. A tie is similar in appearance to a slur, however slurs join notes of different pitches which need to be played independently, but seamlessly.
Road surface marking Broken lines that are wider and closer together than regular broken lines are called continuity lines. Continuity lines on the left side of a lane denote that the lane is about to end and that motorists must soon merge left. Continuity lines on the right mean that the lane will continue, but traffic may merge into it ahead.[21]
