On the sheet music I am playing, I have faced 3 simile Mark each on different bar continuously. Does it mean I should repeat 3 measures back ?
The marking simile or sim. instructs the performer to continue to play something in the same way (in a similar way, I guess is the easiest way to remember this translation from Italian). For instance, a bar or passage of music may have staccato markings over each note; a marking of simile over the following notes would tell you to continue to play staccato. It saves continuing to write performance markings which remain the same.
