In general, first of all, you must be familiar with the phonemic arrangement of dulcimer, and adjust the position of the rollers (commonly known as balls) of the dulcimer roller plate in advance. The left roller is horizontally arranged in a line, and the right roller is centered. Make sure that the interval relationship between the double-sided phonemes of the treble bridge basically meets the requirements of a pure fifth, an increased fourth or decreased fifth, or a major third.

Tuning generally starts from the a1 note marked on the phoneme map, that is, the a1 (mid-tone 6 of the C scale) on the right side of the fifth phoneme from the top of the dulcimer treble code (the first piano code on the left). Then adjust it upwards according to the relationship of fifths.

Starting from a1, you can then turn up the treble E, the middle E and the bass E…. Expressed in simple notation, that is, the downward tuning method starting from C key 6 is: 6-2-5-1-4-b7-b3-b6-b2-b5-b1(7)-3-6..., upward Tuning: 6-3-7-#4-#1-#5-#2-#6-#3(4)-1-5-2-6…,

When conditions permit, use a tuner to calibrate the tuned pitch, and adjust the tuned pitch according to the height value required by the standard sound.
