In fact, the 402-type dulcimer is basically the same as the 401-line dulcimer.
1. It adds an active bass piano code, which can be set as two-point bass fa (F), or E, E-flat, or two-point bass the player needs to use, so the first The piano bridge can be tuned to F (or E), G, A, B, C, D, E, #F, #G, #A, C, etc.
2. Starting from the second row of bridges on the right, starting from the first bridge close to the player's body, starting from #C, which is a little lower, and moving up the major second, it will start from #C─ until the sound of G.
3. The same principle applies to the third row of piano keys. Starting from the lower pitch "A-flat" on the first piano instrument that is closer to the player's body, the tuning will start from "A-flat". A" all the way to the high E.
4. The left half remains the same as Type 401.
Extended information
The timbre of the dulcimer should be granular and have its own personality. If it does not have its own timbre characteristics, the sound will be flat and scattered, and it will be ignored by others. The instrument is swallowed and cannot play its role. Therefore, the timbre of the dulcimer directly affects the quality of the band. The playing method is very important. The production of good tone requires not only high-quality instruments, but also correct playing methods.
In order to make the dulcimer sound better, the following four points are for reference:
1. Hold the keys correctly
"Three-finger holding keys" refers to the thumb, Hold the keys evenly with your middle and index fingers. The key is that the belly of the middle finger is close to the key handle. The purpose is to hold the key with the three fingers tightly so that the key and the hand become a whole and become a forward extension of the fingers. This will facilitate the control of changes in strength. Problems that tend to occur when holding keys with three fingers are: first, the thumb tends to protrude, and second, the middle finger often cannot stick to the key handle.
2. Turn the wrist
When the three fingers hold the key, the task of playing up and down is handed over to the wrist, which requires the wrist to rotate straight up and down. Only in this way can the key head strike the strings from the front and obtain a good tone. The wrist is a "universal axis" that can be rotated at any angle and is very flexible, but it is not easy to rotate it straight up and down. The training method is to clasp your hands together, or half-clench your fists together, and do not separate them, and rotate them up and down. The purpose of turning straight up and down. If you don't practice like this, it will easily cause the wrist to turn outward or inward, which will cause great difficulties in future performance and will be difficult to correct, so strict requirements must be met from the beginning.
3. The position where the key head hits the string
The key head is about 5 cm long. It is required to hit the string from the middle and back position. This position produces the strongest sound. Generally speaking, the sound is best at a position 2.5-3 centimeters (one inch) away from the code. During training, you can pull a line on the panel and stick it with tape on the front and back. Over time, you can hit this position accurately.
4. "Elastic Strength" Exercise
The correct name for playing the dulcimer is playing the dulcimer. The keys should be elastic, which means playing with "elastic strength". According to the performance practice , you can use the "key return" training method, that is: if the key is 20 centimeters high from the string when you hit the string, after playing it, quickly return to the height of 20 centimeters. Remember to deliberately return to the original position through your wrist. The height of the key, the shorter the moment when the key hits the string, the better. "Return key" is the key to generating elastic strength.
