1. Wood and timbre of the piano
● judging from the appearance - the best way to judge the timbre proced by using different wood is to look at the hardness of the wood used. In short, the timbre of the wood with higher hardness will be brighter and clearer, and that of the wood with lower hardness will be brighter and clearer; Sensitive;, The delay of sound is better than that of wood with high hardness. If the design is correct, the use of wood made of these two materials at the same time will be of great help to timbre performance. Furthermore, we can also judge the timbre of the piano from the color of the wood. This seems unscientific, but think about it. Are the timbres of the brighter wood (such as maple, alder, ash) brighter than those of the dark wood (rosewood, walunt, zebrawood)? Finally, the weight (density) of wood is also one of the ways to judge the timbre. The timbre of the lighter wood is clearer and brighter. Although the heavier wood does not have excellent high and medium frequency, it has full and mellow low frequency
● the combination of different materials - the piano made of different wood is beautiful in appearance, but if it is overused, it will not be good for the timbre, because the more different wood is used, it means that more glue must be used to join the connected parts, and the resonance of glue to the object is poor, so it will have a considerable impact on the timbre. However, different timbres can be proced by combining different pieces of wood; Hard 39; On the other hand, the use of the back is more convenient; Soft 39; If you have a good wood, it will show a clear low frequency and keep a good medium and high frequency. In addition, the neck made of different wood will not only be stable in structure, but also change the quality of timbre, because each kind of wood resonates at different frequencies. Therefore, the resonance of sound waves with different wood materials will not be limited to a certain frequency
● neck through is also very different from bolt on in the degree of vibration inction. The through neck has better sound delay and fullness of bass than the connecting neck, although the connecting neck has better bass inction than the through neck (especially the b-string of 5-String bass), However, e to the human hearing, the connected neck is more solid than the through neck, because the human ear will have an impact on the insufficient part of the audio; Make up for 39; It also has an effect on turbid sound; Conjecture 39; The ability to do so
● e to the graal lack of high-quality wood, the destruction of rainforest by human beings has also increased the price of wood and other factors, people began to develop synthetic substitutes. The use of graphite is the best example, which has a good performance in the delay and stability of timbre
● other factors - in addition to the material used in the wood and the way it is connected, there are other factors that affect the timbre of a piano, such as accessories, paint baking, polishing, pickup and circuit, etc. In terms of accessories, it can be made of brass, aluminum, steel or synthetic materials. Each material has a different performance on timbre, but copper is generally the most commonly used, because it has the best continuity of sound, while aluminum and steel bridges have a brighter sound. A good bridge must have several points: first, it has a good connection with the body. Second, the string has a solid support. Third, good intonation adjustment ability
in fact, I think it's a good piano to use conveniently with appropriate adjustment. If you need timbre, you can find a specific bass

2. There are two kinds of MTD, one is the original MTD of American procts, such as the model mtd435 535 635,
it is a famous first-line brand of American handmade goods, and the price is not cheap. For 535, even the second-hand is more than 20000 take off
the timbre is more general. In fact, for bass, when it reaches a certain price level or above, the timbre is generally more omnipotent or more moderate
the other is MTD Kingston made in Korea, the off-line brand of MTD, has a medium price and is also widely applicable, but its configuration and technology are a little more prosperous than the main brand

3. I think bass is OK, but little finger is still boring. This really depends on the usual exercise. The second best way is to distribute the work of the little finger as well as possible, let it move on the 1st or 2nd chords as far as possible, or let it move with the ring finger, and the strength of the two fingers will be much greater.
4. I was a bass imitator! 5 strings (usually 4 strings are enough)! 1200 (bass) + 300 (exercise box) + 10 (2m connecting line), enough practice at home! When the hand is better, buy a real piano! The effector can not be used for the time being! It's too expensive! Or pay for it! Find a teacher to lead for a while, start practicing hell bass
5. In fact, bass is very easy to use, but it's only easy to use. If you haven't learned musical instruments before, then bass will make you a musician faster than other instruments. However, it's very difficult to master. Bass skills are no less than guitar skills. Moreover, when you practice, bass is more boring. After you learn to play root, you can play with the band, even if the volume turns down, It's much faster to make progress with everyone in the band than to play by yourself.
it's not recommended to consider the price of imitation piano. The price of squire in Xi'er is about 900. If you have 1000 to 2000, consider Ibanez GSR series. The workmanship is very good. In this level, the timbre is very good. If you have 2000 to 3000, consider CORT's B GB Elbow series and Warwick's rockbass series, If you have Ibanez SR Series in stock, you can also consider it. The biggest feature of this series is its beautiful appearance. If you have more than 5000, it is recommended that you consider Warwick made in Germany and fender made in the United States

7. Ebanna's high-end piano is very cool, but the low-end ones are average, and the ones below 4000 are all low-end ones.
it's better for beginners to have Squier's, No matter how high it is, it's really boring.
because beginners don't have a good grasp of the strength of the piano, and they don't know how to maintain it, and they do a lot of damage to the piano.
a 2000 or so violin made in Indonesia plus 1000 or so boxes is enough for you to play for three years. If it can't satisfy you after three years, it's worth changing a good one.
beginners can buy 1000-2000 sq, and it's better to be made in Indonesia.
1, The strength of fingers also needs to be contacted for a period of time to press the bass string
2. It's not necessary to start with 5 strings, and it's not necessary to use 5 strings in mianji's song, but it's the same with 4 strings.
the skill of 3.5 strings is better than that of 4 strings, because it will proce resonance, so it's difficult for beginners to press the thumb on 3 strings and lean on 4 strings, so it's easy to give up.
so don't pursue appearance, look at your fingers more, Like the style, choose a thin neck, style consistent with the bass bar

8. The main proction processes of PU synthetic leather are wet process and dry process. The wet process includes single coating process, impregnation process and immersion coating process, while the dry process includes direct coating and scraping process and release paper process. Wet process is a semi-finished proct, commonly known as bass, which can only be finished after dry process and other post-treatment
the typical dry proction process of release paper is shown in Figure 1
in the dry process, the release paper is generally used as the carrier, and PU resin slurry is coated and scraped on it (generally for 1-2 times), then it is put into the oven, heated and dried to remove the solvent in the resin to form PU polyurethane film, and then the bass or other substrates and PU polyurethane surface are bonded together through the adhesive layer to form synthetic leather procts, which are cooled and cured, Finally, the release paper is separated from the synthetic leather to form the finished proct
in the dry process of PU synthetic leather, toluene, DMF and butanone are widely used as solvents. Due to its toxic, teratogenic, carcinogenic and reproctive toxicity, it will cause irreversible and serious damage to the human hematopoietic system, nervous system, important organs (liver, kidney, digestive system) and even bone marrow in the process of long-term exposure, which has significant hidden danger to occupational health and environment. If we want to fundamentally control the impact of synthetic leather organic pollution waste gas on the environment and health, we must start from the comprehensive replacement of solvents, using new, slightly toxic or non-toxic aliphatic solvents without benzene ring structure to replace the currently used toluene, DMF, butanone and other toxic mixed solvents, and take corresponding control measures.

9. Squier, a sub brand of fender company, is low-end, but it's not the piano of Fenda at all...
one Squier 3900 seems to be very popular, about 1000
it's hard to learn anything... But as long as you learn it, it's not difficult.
