I am puzzled by the number put in the square in the sheet music. Can anyone tell me how to play?

  • Interesting, also the upside down T marks. I would expect them to be explained in the book. They are not part of standard notation. They seem to indicate the bass string on which the next note will be played, so perhaps it's some guideline for fingering. Commented Jan 19, 2022 at 1:52

    Thanks for your response! The arranger writes “I used unconventional notation. I hope you understand what I have in mind” 😀

  • Some upside down T's have a 4, 5, or 6. Some have nothing at all. Their vertical position isn't consistently aligned with staff lines or staff spaces or noteheads. Does a pattern emerge eventually? What is the arranger's full name -- does googling that find any hints? Commented Jan 22, 2022 at 1:43

At each point a Barre is recommended and the number in the square box is the number of strings it should cover. I would need to see a few more pages to be absolutely sure.
