We will use the middle string as our guide for tuning the thin string!
For Hon Choshi or San Sagari tuning:
Make sure that the middle string is already set for Hon Choshi/San Sagari.
Hon Choshi:
Press position ‘6’ on the middle string.
Listen to the pitch and tune the thin string until they match.
San Sagari:
Press position ‘4’ on the middle string.
Tune the thin string until they match.
For Ni Agari tuning:
Ensure that the middle string is set to Ni Agari tuning.
Press position ‘4’ on the middle string and tune the thin string until they match.
Now you know how to change tunings without using a tuner! Again, every tuning is based on the thick string. Set the middle string from the thick string, and then set the thin string from the middle string.
