一、RAV Vast的源由與發展史?

RAV由一位熱愛手碟的工程師Andrey Remyannikov發明，透過電腦軟體計算音區的複雜形狀，以實現每個音區上泛音的精確調節並消除雜音，該技術也獲得專利。所以它不僅是一種美妙神祕的樂器，也是現代科技注入職人精神的展現。早期的原型是在 2013 年製作的，至今已至第五代（點我看RAV歷史與世代故事）。RAV在全球愈來愈受喜愛，獲得許多音樂家的支持，像是Nadishana與Kanecao。後續將營運擴展至美國Pennsylvania與歐洲Armenia，確保我們都能持續感受到RAV的美妙。

二、RAV Vast與手碟(Handpan)有什麼不同?

它們都是用手打擊的樂器，但是屬於不同的樂器，例如鋼琴和電子琴。因為採用不同的生產技術：RAV的音區是在整片金屬圓盤上精細切割，而Handpan的音區則是錘壓而成。Handpan在每個音區上有2個泛音，而RAV則有4到7個泛音。 
RAV的延音比手碟長很多，而且音色表現也不同，RAV與手碟Handpan沒有誰更好的分別。從某方面看，RAV鼓更為精巧，更耐敲打與碰撞。且基本不需要調音，使用與保養上較為輕鬆容易。

三、如何選擇RAV的音階?

"該選哪個音階最合我自己？" - 這是多數剛接觸RAV的人所遇到的問題。你可能已經看了 10-100 個影片和評論，現在有兩三個喜歡的音階，但你還是無法決定哪個是最棒的，太多的調式讓人有選擇困難症。
這邊建議別單純用你的意識來選擇，請多聽從你內心的聲音。首先，請觀看我們所提供的所有音階的影片，然後當你選出前兩三個時，觀看每個的另一些新影片，並給自己一些時間，兩三天或更長時間。如果你覺得你需要更多樣本，請觀看更多你選擇的音階的影片。並聽從你內心的聲音，因為這個樂器是為了你的「深層本質」，而不是為了外界或社交媒體等等，而你的「深層思維」應該選擇正確的那個。
再一個重要的細節：無論任何人說什麼，所有的音階都是由彼此和諧的音符組成，並適合自由即興演奏，所以只需聽從你的直覺。
額外的參考是，全球售銷最好的四種音階，已列在官網的熱門款式。

四、RAV Vast與RAV Moon有何差異?

Vast是我們系列中的旗艦型號。當你彈奏它時，它會產生一種豐富、隆重的聲音，影片不太容易呈現出聲音的真正差異;親自體驗才能感受到差異。與Moon相比，Vast比Moon 的聲音深沉兩倍、更有豪華及張力感。Moon的音調明亮但不那麼深沉，有輕快愉悅的感受。
演奏完Moon之後再玩Vast是一種升級的體驗，你會立即感受到更高工藝的精緻跟細膩。更專業級的樂器，具有強勁的聲音，與身體和靈魂產生深刻共鳴，聲聲都直及靈魂深處。這就像將平台鋼琴對比立式鋼琴，產生的音感是不同的。
如果你正在尋找一種深沉、令人印象深刻且完全迷人的聲音，那麼Vast是您的明確選擇。為了獲得更深刻的共鳴和更強的衝擊力，請選擇比 “B” 更低的調式。Vast的尺寸較大，技術也更多元複雜性，我們的工匠需要更多的時間來製作。我們在製造Vast時沒有辦法簡化任何步驟，這就是為什麼它聽起來如此純粹和乾淨的原因。
Moon也非常出色，但在設計它時，我們不得不犧牲一些功能，使其更加完美和輕便。以下是兩者對比的參考影片：

五、不同顏色的鼓面，聲音有差別嗎? 有仿貨嗎?

我們對所有款式RAV的聲音標準要求很高，在製工上保持高品質的一致水準。所以即使顏色不同，對於音質或音色上沒有差異。
RAV的類似仿品如下，請認明別購買到假的，聲音與品質差異非常大。

六、RAV在台灣有幾家代理? 與國外購買的差別?

daydayNice是台灣總代理也是獨家代理(原廠授權証如下)，台灣售價比歐美官網價格要另加稅與運費(Vast約US360=NT11,800)再加台灣進口關稅(約NT4,000)後的價格還便宜。更重要的是享有台灣在地三年保固與終身保修的服務。

七、初學者需要用鼓棒來彈奏嗎?

玩RAV的最佳方式是用手，因為這樣可以讓你充分感受樂器的魅力。我們的線上教程將幫助你儘快學會。但鼓棒可以讓您發現樂器的新聲音與不同表現方式。

八、RAV底部的木塞可以拿掉嗎?

當你演奏RAV時，木塞必須固定在底部，這樣敲擊時空氣才能在樂器底部旋轉，然後通過鼓上的音舌震動排出時，才會發出最飽滿和最深沉的聲音。

九、如何保養我的RAV? 

第五代RAV製作採用了新型終極塗料取代疏水塗層來防止生鏽，您再也不用像過去一樣要定時上油保養。有灰塵只需用乾布擦拭，避免用含酒精的清潔劑或精油。與Handpan手碟相比，RAV更耐高溫與耐用，且基本不跑音，長期不使用可上一些凡士林油或矽油後保存。

十、下訂後到貨時間?

現貨款式：付款後台灣1~3天（不含例假日）到府，運送國外則依各地不同。
預購款式：付款後12~30天（不含例假日）到府，依歐洲工廠製程來決定時間。

1. What is the difference between handpan and Kongling drum? The source of handpan源？

Many people often think that Handpan is the Steel Tongue Drum, the steel tongue drum. In fact, these are two completely different percussion instruments. It is different from the Hollow Drum played with drumsticks. The handpan is usually placed on the player's legs or on the handpan stand with bare hands. Of course, the performance depends on the player's habits and skills. Some people play the ethereal drum with bare hands and put it on their legs. It's just that it is difficult for ordinary beginners to play a good tone in this way, so they will make good use of the ethereal built-in Play on a tabletop or any flat surface with the padded feet and use the dedicated sticks to get the best sound from ethereal drums用專用鼓槌，以發揮空靈鼓的最佳音色！

Because the structure and sounding principle of the handpan are different from the empty drum, the handpan can produce softer, ethereal and changeable timbres with the change of the player's skills, whether it is a slow song or a fast song, it is also more suitable for free creation and solo performance. It is much more difficult to get started with Konglinggu, but it also has more infinite creative possibilities.無窮的創作可能性。

SwissPAN ArtThe company was founded by Felix Rohner and Sabina Schärer in 2000 and presented at the Frankfurt Musical Instruments Exhibition in 2001. They named it and registered it as Hang and took the sound artwork as its design concept. Its unique, mysterious and beautiful sound has attracted a lot of interest. but due to批愛好者。但由於PAN ArtThe undisclosed method and the complex and time-consuming production process lead to short supply應求。

2007 USAPantheon SteelAsk an experimental question on its official website, which says Interested in the HANG PAN or HAND PAN. The purpose is to understand the interest and demand of the global opponents and consider whether they want to produce. In 2009, they produced the first instrument similar to Hang. Halo used Handpan to describe the newly developed instrument to distinguish it from Hang. The company then supported and helped many Handpan producers to promote the development of handpan around the world.推動了手碟在全世界的發展。

2. The principle and material of the hand disc should choose a few tones的？

Handpan is a self-sounding body instrument composed of two deep-drawn hemispherical steel plates. The two steel plates are bonded from the edge to form a hollow resonant cavity.在鋼鼓（steelpan）The technology has added Helmholtz resonance. There is a raised part in the center of the upper hemisphere called Ding, surrounded by 7-10 oval-shaped small pits with a central depression like a steel drum called Note, which can produce different pitches and are controlled by Arrange from bottom to top in a Z-shape from low to high. Players can alternately play with left and right hands in ascending or descending order. Each range has a fundamental root note, a harmonic long axis and a fifth harmonic short oval axis, which can be matched with the performance skills according to the needs of the timbre. Different to obtain ever-changing timbres such as bright, dull, short, long, etc.技巧不同的獲得明亮、沉悶、短促、悠長等千變萬化的音色。

The lower hemisphere has a smooth surface, and the central part has an involuted opening at the edge called Gu. It can be played with the palm to excite the airflow in the cavity and produce Helmholtz resonance. It produces a sound similar to the Indian clay pot drum Ghatam or Udu. Play the bottom with your fingers. The edge of the opening can make a sound similar to the chiming of a small bell能發出類似小鍾叩鳴的聲音。

At present, there are roughly two main materials for the hand plate: carbon steel and stainless steel. Others are also rare, and the lower hemisphere is made of different materials such as wood.異材質。

Hand discs made of carbon steel basically have a thicker and fuller sound, but the sustain is shorter. They are more likely to rust when exposed to sweat and require frequent maintenance. Therefore, in recent years, most of them have been added with nitriding process to make the carbon steel material better anti-corrosion. Rust performance and good nitriding treatment will allow carbon steel materials to obtain longer and better sustain effects, so they are more popular with the public效果，因此更受大眾喜愛。

Stainless steel sustains longer than carbon steel and is relatively less prone to rust. The maintenance period can be longer or even no special care is required. Under normal use, the sound can be selected according to personal preference. The current international mainstream is gradually developing from carbon steel to stainless steel. Beginners are also recommended to choose Stainless steel is easier to play good sustain and get a greater sense of satisfaction音，獲得較大的滿足感！

Although the mainstream of the market is changing, there are still a group of loyal players who love carbon steel materials. They love the good sustain and full-bodied timbre of carbon steel materials. This is purely a personal hobby and an intuitive feeling, just like food preferences. Those who choose these two materials have doubts, are curious, or want to find out. When they come across a musical instrument and listen to it, they will make a decision. Everyone has different feelings and preferences. Believe in your ears and first instinct, it will often be your favorite.往往就會是您的最愛！

In recent years, the production technology of hand discs has advanced by leaps and bounds. Multi-tone hand discs have become the mainstream pursued by hand disc enthusiasts. From the early 8-tone 9-tone to the current 10-tone mainstream, even super-high-priced hand discs with more than 20 tones have a specific market love. It is generally recommended for beginners to learn 9 to 10 tones, followed by 11 tones, because there are many corresponding learning materials, videos and teachers that can be found. Hand discs with more than 13 tones will also be equipped with sound zones in the lower hemisphere. Beginners will place them on their legs. The difficulty will increase greatly when playing on the table or on the hand disc stand, so it is not recommended for ordinary beginners to get started. Of course, you have the independent choice to enjoy the fun of the challenge.，您擁有享受挑戰樂趣的自主選擇性！

3. What is nitriding treatment in the production process of hand dishes?理？

1. Material selection
Stable material is the key to the quality of the hand plate. Steel is generally produced in batches, calculated in tons and furnaces. There must be slight differences in each batch. This is unavoidable. The hand plate manufacturer must do everything possible to ensure stable quality.確保品質穩定。

2. Deep drawing hydraulic machining or hammer forming Sinking into hemispherical shape成半球形
There are many ways to pre-form a hemispherical shape. Each has its own advantages and advantages. It depends on the choice of individual manufacturers. The forming method is also related to the material, the subsequent process and the preference of the tuner. The result of a series of cross-selections will finally determine a The quality of a hand plate is good or bad手碟品質好壞。

3. Heat treatment + nitriding
In recent years, the mainstream of the process generally performs heat treatment + nitriding before the initial adjustment. The nitriding process itself must be heated. There are also cases where this process is performed after the initial adjustment. There is no absolute right or wrong in the choice of the manufacturer. The final quality is important質才是重要的。

4. Note Plan and Dimple & Tone Fields Forminging）
The sound area includes the dome or the dimple (Dimple) is formed at this time. Generally, each sound area is positioned and shaped, and the extrapolation of the upper half of the non-audio area is also included. At the same time, the opening and inner curvature of the lower half are included.曲成形。

5. Initial adjustment and tempering heat treatment
After the forming is completed, use hammer to do simple preliminary tuning for each sound area, and then perform tempering heat treatment to release the stress of the metal after deformation to consolidate the stress around each sound area, and then perform tuning for each sound area音區做調音。

6. Tuning
The process of tuning with various mallets and tuners. Generally, commercially available mallets cannot satisfy hand-pan tuners. Most hand-pan tuners have their own unique tools and tuning methods.音工法。

7. Temper again and tune again until the tone is stable
This process may not be chosen by every master. It depends on the material master’s experience and judgment needs. The purpose of this process is only to seek the stability of the tone. The choice or not will determine the final quality.定最終的品質。

8. The final fine-tuning of the overall fine-tuned tone and temperament is entirely dependent on the individual situation and whether it can be adjusted.整而定）
After the tuning is completed, it will usually be placed in the natural temperature for a period of time and the final inspection will be done before the final shipment. Metal has its natural elasticity and ductility. After stabilization, there may still be slight timbres and tone shifts before leaving the factory. After the hand plate has been joined up and down to become a finished product, necessary fine adjustments will still be made according to the master's judgment and inspection. This is entirely based on the master's experience and judgment.照師傅的經驗判斷而定。

9. Calibration and protection before leaving the factory, oiling, spot removal, micro-grinding and scratch removal去刮痕）
The final inspection for appearance and tone is usually combined with the previous step, followed by necessary oiling and anti-rust protection before packaging, and then packaging後包裝。

10. Packaging A key procedure to keep in good condition to your hands序）
We all know that the hand disc is made of metal, and the tuning is done by hammering, so any collision may cause the hand disc to go out of tune and cause damage. Good hand disc manufacturers can say that there is no limit to the protection work of the shipping package. Anything that can protect a 4 Packaging protection with a weight of ~5 kg may be used. The packaging method is also changing with each passing day. The main reason is to reduce the overall weight to reduce the cost of shipping. The packaging is generally about 7-10 kg.一般大約在7~10公斤左右。

11. It takes about 9~20 days for the shipment to be shipped out of the customs and taxed, shipped into the customs and paid for duty, and then shipped to the government再運送到府）
Currently, there is no independent manufacturer of hand discs in Taiwan, so they all rely on imports. It takes a lot of steps to transport them from the place of origin to your hands. Ask any senior players who have purchased hand discs from abroad to understand the process and cost. How much of this we take care of for you all the way to save you the hassle，省去您的麻煩。

－Nitriding treatment－
Nitriding, also known as nitriding, is a chemical heat treatment process that diffuses nitrogen into the metal surface to form a hardened surface, which can improve sound quality, reduce mutual interference between sound zones, reduce cavity noise and metal steel hard percussion sounds, and enhance sound purity. The sound is more concentrated and the firmness of pitch is enhanced，增強音準的牢固度。
Our hand plate is preset to the classic D minor and Kurd scale distribution. The latest nitriding technology is used to place the hand plate embryo body in a closed high-temperature furnace. The nitrogen decomposes and reacts to produce a large number of active nitrogen atoms. The steel surface of the hand plate is fully absorbed and nitriding is effective. Improve the hardness and wear resistance to make the sound of the hand dish more ethereal, maintain the pitch for a long time, scientific thickness design and make the hand dish more sensitive更加靈敏。

4. Which one would beginners recommend to buy?？
