Tablature fundamentals
Shamisen position numbers and strings
Shamisen tablature is direct: the row selects a string and the number selects a position. Tuning determines the pitch that combination produces.

Three rows represent three strings
Follow the score convention consistently from the first measure. The visual row—not the number alone—identifies which string is played.

Zero and numbered positions
An open string is normally written as zero. Higher numbers indicate locations along the neck. Position labels are a performance map rather than a fixed universal pitch name.
Why tuning matters
Changing from Honchoshi to Niagari or Sansagari changes string pitches. The physical position can remain the same while the sounding note changes, so every score should make its tuning clear.
