How to make a special rosin block for erhu

Good rosin. The dust is small and easy to get on and not easy to fall off, on the contrary, the dust is large and not easy to fall off. So, can you make good rosin yourself? The answer is: Yes. Let's talk about the method of making it, the first step is to go to the farmer's market.

Buy a piece of raw rosin (usually a few dollars, the color is light yellow and transparent), the second step is to take an iron container and put the rosin in, put it on the fire, and cook it over medium heat (nothing needs to be added) until the rosin is boiled into a brown opaque shape (usually a few minutes). Take the small carton commonly used in life, such as a small medicine box and the like, turn off the fire, can not be turned off, otherwise, the rosin will cool down quickly, use a dry spoon (can not contain water) to put the cooked rosin into the carton little by little, not too fast and the bottom of the carton must be closed (this process must be careful, be careful not to be burned), so that after using up the cooked rosin, you can make more than a dozen pieces of rosin, 5 years do not need to buy rosin, and the processed cooked rosin has small dust, It is easy to get on and not easy to fall off. When you use it in the future, you only need to tear off the top paper once.

The production method of the special rosin block for erhu is as follows:

1.Ingredients: rosin, board (flat container such as bamboo board and plastic board), alcohol (to dissolve and help the ingredients mix), erhu bow (to scrape the rosin to make it soft).

2.Place an appropriate amount of rosin into the board.

3.Heat the rosin with alcohol so that the rosin dissolves completely.

4.Add an appropriate amount of butter and continue to heat to allow the water in the rosin to evaporate.

5.Add a small amount of pine oil soot, quickly stop heating, and keep warm for about a minute.

6.Pour the melted rosin into the mold and take it out after cooling.

The above are the steps to make the rosin block for erhu, the production process requires professional skills and laboratory equipment support, and the ratio and operation need to be carefully considered.

The production method of the special rosin block for erhu is as follows:

Materials: 1Rosin: It is recommended to choose high-quality, transparent rosin.

2.Boards: Bamboo boards, plastic boards, or other flat containers can be used.

3.Alcohol: Used to dissolve and help mix ingredients.

4.Erhu Bow: Used to scrape rosin to make it soft.

Steps:1Prepare a flat bamboo or plastic board as a container, and then put the right amount of rosin in the board.

2.Pour the alcohol into the rosin until the rosin is submerged in the liquid.

3.Allow the mixture to soak for 24 to 48 hours to allow the rosin to dissolve thoroughly.

4.In the dissolved rosin liquid, put in the erhu bow and scrape, so that the rosin can be slowly softened. When the rosin becomes soft, you can stop scraping and prepare for it.

5.Pour the rosin mixture into a mold and flatten it with a tool such as a tape measure so that it is more homogeneous.

6.Leave for a few hours to allow the mixture to set and fix naturally.

7.Take out the rosin block and shape it with a spatula to make it look neat.

The rosin of the erhu should be rubbed evenly on the strings of the erhu, and here are the specific steps:

Tools Required: Rosin.

1. First of all, wrap the rosin in oiled paper and take out the rosin.

2. Pinch the lever with your index finger and thumb to fix it.

3. Rub the rosin along the long axis of the string to the outside of the string.

4. Continue along the long axis of the string and wipe the rosin burner to the inside of the string.

5. In the same way, rub the rosin on the top side of the string.

6. Finally, rub the rosin on the underside of the string.

7. The rotten eggplant is wiped off with rosin, come and try it, it can be seen that the feel has become better and the effect is good.

The usage of erhu rosin is as follows:

Rub it hard and rub it lightly". The so-called "heavy wipe" is not to wipe with gravity, but to focus on wiping, in fact, it is still to wipe a little lightly. "Lightly", it refers to pressing, that is, the pressure exerted on the bow hairs by holding rosin, and the pressure exerted on the bow hairs when rubbing rosin should be appropriately lightened.

"End to edge". The so-called "to the end", each time you rub rosin, you must rub it to the tip of the bow and the two ends of the bow; "To the edge", rubbing rosin should be rubbed to the inside and outside of the bow hair (up and down), left and right, generally rubbing the inside and outside (up and down) can basically involve reaching the left and right, but if it is slightly insufficient, it should be rubbed left and right.

First full rub". The new bow is rubbed with rosin for the first time, and it must be rubbed once full. Because the first time on the rosin is more laborious and time-consuming, it is common for someone to grind (or hammer) the rosin into powder with a tool, and then sprinkle or wipe or accompany the bow hair, the rosin powder made by this method is uneven, the bow hair is not easy to hang incense, and dirty, which is very unscientific and undesirable.

"Wipe frequently". Erhu gong rosin should be rubbed frequently, generally wiped once every 2-3 hours, or wiped once according to the need for the friction of the bow hair to become smaller, and it is enough to wipe a few back and forth from beginning to end each time. Each time you rub the rosin, you must use it evenly, hold the rosin arm to run easily and smoothly, and constantly rotate the rosin to make it evenly rub the bow hair, so that the rosin surface will not be ground into a furrow, which is not only economical and beautiful, but also ensures that the rosin is fine and even.

In this way, we can effectively ensure that the rosin powder adsorbed by the bow hair of the whole bow is uniform and the friction of the bow hair is uniform, so as to ensure that the pronunciation of the whole bow is normal during the whole performance process, and there will be no uneven pronunciation in the bow movement, so as to improve and ensure the stability of the hand feel and control force of the bow movement.

The steps to use the rosin of the erhu are as follows: prepare the rosin, prepare the erhu bow, apply the rosin, and gently pluck the bowstring.

The materials and tools required to use the rosin of erhu are as follows: erhu, rosin.

1. Prepare rosin: Make sure the rosin is dry and not clumping or damp. If desired, the rosin can be scraped into fine granules using a knife or spatula.

2. Prepare the erhu bow: hold the erhu bow in your hand and make sure the strings are tight. In general, use a rosin box fixed to the bow tail and gently pluck the rosin box so that the rosin particles can be evenly distributed on the bow hairs.

3. Apply rosin: Use your fingers to gently pluck the rosin box so that the rosin particles are evenly spread along the arch hairs. You can start with the tip of the bow and apply evenly towards the crook of the bow.

Be careful not to push too hard to avoid dropping the rosin particles. Make sure the rosin particles are evenly applied to the bow hairs. You can use your fingers to gently press the bow hairs to distribute the rosin evenly along the bow hairs.

4. Pluck the bowstring gently: Use a rosin-treated bow and pluck the bowstring gently. It can be plucked several times to make the rosin fully blend with the bowstring. This increases friction and gives the strings a clearer, brighter tone.

A combination of erhu and rosin

In erhu performance, rosin plays an important role. It increases friction and produces a clearer, brighter tone from the friction between the bow and the strings. The use of rosin can also increase the volume and expressiveness of the strings.

In addition to using rosin to increase friction, there are some players who also use special rosin as needed. These specially crafted rosins may be formulated according to the player's requirements and style to better meet the player's requirements for timbre and volume.

The preservation of rosin is also important. In order to ensure the quality and effectiveness of rosin, it is recommended to keep rosin in a dry environment to prevent moisture. Some players will even place some desiccant in the container where the rosin is kept to help keep the rosin dry.

The use of rosin has an important impact on the technique and effect of erhu performance. Players can choose the rosin that suits them according to their needs and style.

Some players may prefer more rosin for more volume and tone, while others may prefer less rosin for a softer and more delicate tone. No matter how much rosin is used, players need to find the best way to use rosin for themselves through continuous practice and exploration. During the performance, the player also needs to adjust and apply the rosin according to the condition of the strings and the time of use.

Erhu rosin is used to improve the friction between the erhu strings and the bow and provide better acoustics. Here are the general steps to use erhu rosin:

1.Preparation:

Clean your hands: Make sure your hands are clean and free of grease or impurities to prevent contamination of the rosin.

Prepare the bow: Make sure the horsehair on the bow is neat and free of impurities.

Prepare the erhu: Make sure the strings are clean and free of dust or dirt.

2.Heated rosin:

A specialized rosin heater or a small metal utensil can be used.

Place the rosin block in a heater or utensil.

Gently heat the rosin with a fire source (e.g., a candle or match) to soften and thicken it.

3.Apply rosin:

When the rosin becomes soft enough, gently rub the horsehair of the bow over the rosin so that the horsehair evenly covers the rosin.

Avoid using too much rosin and just apply it gently. Too much pine source incense may cause the bow to be too sticky.

4.Fingering rosin (optional):

Some players like to apply some rosin to their fingers to increase the stickiness of the fingering and help with better grasp of the strings.

If you choose to do this, make sure to use only a small dot of rosin and distribute it evenly across your fingertips.

5.Performance:

Wait a while for the rosin to dry on the bow and fingertips before you start playing.

Rosin should be crumbling to help provide better tone, volume, and control.

Note: Be careful when using rosin and do not allow it to come into direct contact with your clothing or strings to avoid soiling them.

Clean the bow and strings regularly to remove old rosin and impurities.

The type and quality of rosin will affect the effect, you can try different kinds of rosin to find the best choice for your erhu.

Here's how to put rosin on the erhu:

1. The rosin on the erhu generally adopts the method of rubbing incense, that is, rubbing the rosin back and forth directly on the bow hair. When choosing rosin, it is best to choose more than mid-range. When rubbing poor quality rosin, it is easy to get bow hairs without hanging strings. The amount of rosin should be appropriate, not too much or too little.

2. When cleaning the new bow of the ponytail and rubbing the rosin, do not wipe it back and forth as a whole. First, rub the 5 cm part of the bow root part repeatedly, then add 5 cm on top of this, rub it repeatedly, rubbing the two planes of the bow hair evenly. When using rosin blocks, change the position with each wipe to prevent the rosin from breaking.

Wipe the entire bow as described above.

3. When the rosin plays the piano, the jujube bow hair feels like it can be hung on the strings. When the bow is pushed down, the sound does not become louder or smaller depending on the amount of rosin. The sound quality is clean and there is no astringency.

Note that if it is necessary to play on stage, rosin would rather rub less than do too much. When rosin gets the bow hair, it needs to be played for a period of time or even longer, so that the rosin and the bow hair can be better combined and the performance effect is the best.

Erhu (pinyin: erhu) began in the Tang Dynasty and is called "Xiqin" and has a history of more than 1,000 years. It is a traditional Chinese stringed instrument.

Erhu, also known as "Nanhu" and "Huzi", is one of the main bowed string instruments (rubbing string instruments) in the family of Chinese musical instruments. The timbre of the erhu is almost the same as the human voice, with a sense of singing and telling.
