Shamisen Tuning Explained: Honchōshi, Niagari, and Sansagari

The shamisen changes the tension (pitch) of its strings depending on the piece being played. There are three basic tuning patterns — honchōshi, niagari, and sansagari — and playing the same numbers on a bunkafu score sounds different depending on which one you use. This article explains the difference between the three tunings and when each is used.

What tuning means on the shamisen

The shamisen has three strings, and before playing you adjust each one with the pegs to set the pitch relationships between them. Because bunkafu only shows which string and finger position to use, the same score produces a different scale depending on the tuning in effect.

Honchōshi

The most basic tuning: a fourth between the first and second strings, and a fifth between the second and third. Most folk and classical pieces are built on this tuning, and it's usually the first one beginners learn.

Niagari

Niagari raises the second string roughly a whole step from honchōshi, giving a fifth between the first and second strings and a fourth between the second and third. It tends to sound bright and festive, and is common in celebratory or upbeat folk songs.

Sansagari

Sansagari lowers the third string roughly a whole step from honchōshi, giving a fourth between both pairs of strings. It tends to sound calmer and a little melancholic, and is often used for quieter or narrative pieces.

How to tune

• Tune the first string to your reference pitch first, then set the second and third strings to match the target tuning.
• Use a tuner to check each string precisely until your ear is trained enough to do it alone.
• Always double-check your tuning before practicing — correct finger positions still sound wrong if the strings are off.
• Some pieces change tuning mid-song; the required tuning is usually noted at the top of the score.
