源于1895年的德产WITTNER 维纳节拍器

Already in the year 1895, Gustav Wittner founded a precision mechanical factory for the production of Metronomes, which his son Rudolf Wittner expanded one by one to a medium-sized industrial plant.

Soon new standards were established. Besides the Maelzel Metronomes, Wittner started producing the "TAKTELL". These Metronomes under the registered trademark "TAKTELL" became such a term of quality, that among the experts of many countries the word "Metronome" was replaced by the word "TAKTELL". Thanks to experience and tradition, newest technologies and modern production methods, Wittner became the manufacturer with the widest range of Metronomes in the world.

Besides Metronomes Wittner manufactures other Musical Accessories (Tuning Forks, String Accessory, Stands etc.) as well as articles for storage and maintenance of Sound- and Data mediums. Since 1975, the third generation is running the company. The Wittner GmbH & Co. KG is worldwide known for the reliability and quality of its products.

顶级云杉音板品牌Ciresa

We are pleased to welcome you in the world of Abete Fiemme.

These pages tell the story of the "tree of music", an extraordinary tree which grows in the forests of the Fiemme Valley (Italy).
From this wood, unique in the world for its resonant characteristics, we obtain soundboards for valuable musical instruments.

A. Stradivari personally chose the spruces in the Fiemme Valley to make his fascinating violins.
Nowadays the "heart" of some of the most famous pianos in the world, is a "Ciresa soundboard ".
The Ciresa Firm, which factory is situated in Tesero - Fiemme Valley, through scrupulous selections and careful processing of this particular spruce, has been producing instruments and sound components of highest quality since more than 35 years.

The Ciresa Firm was established in Tesero- Trento in 1952 by Enrico Ciresa (1922-1991), who had acquired a great experience working for the harmonium and piano factory Delmarco & Bozzetta in Tesero at first and then for the well known piano factory Schulze Pollmann in Bolzano.

The first productions were keyboards for pianos and various models of harmoniums, immediately appreciated for the quality and sonority in both domestic and foreign markets.

In 1978 the whole production moved into the new modern factory built in the industrial area of Tesero, where the Ciresa's plant is up to date.

From the 70ties, after the sudden and great development of electronic keyboards, the market of the traditional harmonium dropped remarkably and continuously, sothat the piano soundboards 'production became the core-business of the firm.

After some years of a high qualitative production, but for the domestic market only, in 1991 the new management developed the marketing, supplying soundboards and ribs to the European piano factories, identifying the product with the trade-mark, awarded by the Magnifica comunità di Fiemme.

Research and Development

Since 2004 in our Research and Development Laboratory is operating a semianecoic box, where we carry out tests and acoustic measurements on the soundboards.
Thanks to these tests we are able to obtain very important technical data concerning the psycho-acoustic efficiency and the characteristics of the soundboards made of Fiemme tone-wood.
This additional service is offered to the customers, in order to improve the quality of our products. This is the statement of the value of our tone-wood.

Our strategy was to make the existance of the "tree of music" and its history known to a wide public, emphasizing the fact that A. Stradivari chose personally the spruce in the Fiemme Valley to make the tops for his famous violins, obtaining from them an extraordinary sound. The Fazioli piano factory, an old time Ciresa's customer, has been also a good testimonial of the quality of the soundboards produced in Tesero.

The first document, that entitled the Ciresa Firm to use the trade-mark of the Magnifica Comunitá di Fiemme, dates back to September 1991.
From that moment we have been working to attain the following three objectives: the improvement of the working schedule in the factory, in order to obtain a product of increasing quality; the pursuit of new customers among the most famous international piano manufacturers; the promotion of the exclusive trade-mark as the image of the Ciresa Firm and its products.

During the first years our products overcame many severe qualitative tests by the most demanding customers, acquiring a good reputation in the new markets.

In 1995 we also started to enter the market of spruce tops for stringed instruments, which are obtained from trunks directly selected in the forest. With the numbered certificate of origin they are very much appreciated and requested by makers of stringed instruments all over the world.

holzwerke-strunz德国实木音板

1820年时，一位名叫皮特·施特伦茨的年轻小伙子在勃莫森林的山区里买下了一把木板锯， 他买锯的目的仅仅为了把共鸣木制成乐

器。当时工业乐器制造还不能或只能造出音调很轻的
乐器木材。但是皮特·施特伦茨，接着还有他的儿子约瑟夫·

施特伦茨却有个构思：他们想制造出尽可能最好的洪亮的共鸣底板。在需要一流顶盖材质的乐器， 弦乐器和拨弦乐器制造者那儿，

“施特伦茨木”的公司简称在19世纪中叶就已是有口皆碑了。 每当需要保住 乐器木材行业最古老的企业名声以及需要拓展肋条木﹑

肋木和键盘木材生产计划时，这种开
拓创业精神就一代接一代地在施特伦茨家族中生机勃勃地传承了下来。

女儿海尔塔在其父阿道夫·希尔茨(1938年逝世)还在世时就与她的丈夫卡尔· 希尔茨接替了企业领导。二战后家族财产被没收，公

司转归捷克政府所有。

巴伐利亚新开端

就象创始人皮特·施特伦茨一样，卡尔·希尔茨也展现了他对这种手工艺术敏锐的感知性， 在接下来的几年内他把建立在巴伐利亚

土地上的企业重新变成了乐器木材同行中的一员。

自1998年起，我 - 托马斯·希尔茨接替了位于袍艮的家族企业领导。我们业已成功地拓展了胶合卡槽， 卡槽件以及椅座的生产计划

。

我们为能拥有世界范围内名列前茅的乐器制造公司作为我们的客户而感到自豪。

Hardman Peck History

From the Stark County News,  Oct. 25, 1872 Toulon, Illinois "They handle the Steinway, Chickering and Hardman pianos, and Mason & Hamlin and Taylor & Farley organs, and the reputation of these instruments is so well established they require no commendation at our hands.  Of the Hardman piano, however, we will say that it is the best instrument for the money in the market."

The Hardman piano Company was established in New York city in 1842 by Hugh Hardman. Hardman pianos soon became known for their fine musical qualities, timeless cabinetry and durability. The house of Hardman progressed steadily and at the 1876 Centennial Exposition introduced the Hardman Art pianos.

In 1880, Leopold Peck joins Hardman with the primary focus on developing the Hardman piano as a noted performance instrument. In achieving his goal for the Hardman piano Peck spearheaded many innovative design ideas and in 1886 introduced an artistic player piano called the Autotone. This instrument was recognized as a piano of unquestionable excellence and beauty.

Picture shown is a turn of the century Hardman upright piano.

Leopold Peck becomes a partner in 1890 and the company is renamed Hardman, Peck & Company. Peck acquires the business in the mid 1890's and the success of the Hardman piano continues.

Upon Leopold's death in 1904, management of Hardman, Peck & Company passes to his son, Alfred L. Peck. Under continued growth, the firm is incorporated under the laws of the state of New York in 1905, capitalized at $800,000.

Carl E. Peck succeeds Alfred L. Peck as company president in 1911. Carl had joined Hardman, Peck & Company in 1890 as production manager. Prior to this he had spent eighteen years in lumber manufacturing in the Black Forest of Germany. By this time the company had retail stores operating in New York and Philadelphia.

The artistic superiority of the Hardman piano had found its proper recognition in the music world. Noted institutions chose the Hardman piano as their preferred piano, and for many years Hardman served as the official piano of the Metropolitan Opera Company.

Picture shown is of the original Bronx, NY factory

Success in the industry did not go unnoticed. The Aeolian Corporation, another distinguished piano manufacturer, showed interest in acquiring Hardman. Having additional resources in manufacturing, finance and capacity the Aeolian Corporation purchases Hardman, Peck & Company. Aeolian expands the Hardman product line, building to the quality expectations of the original company.

Today, Hardman, Peck & Company continues to build quality pianos to meet the demands of every pianist. These pianos offer an outstanding value in a complete line of console, studio, professional upright and grand pianos; all which are available in a variety of styles and finishes.

Hardman, Peck & Company - quality crafted pianos from the world's finest materials since 1842.

【世界钢琴质量排名】

钢琴可以分为两种类型的，主要是根据制造商的用意来加以划分。一种类型是制造达到很好标准，甚至是尽可能达到最好标准，价格则根据制造成本和营销成本来确定。我把这种类型的钢琴称为“演奏级”钢琴。另一种类型的钢琴以特价出售，通过调整材料、工艺、生产方法和地点来满足价格要求，我称之为“消费级”钢琴。两种类型的钢琴都是有必要的，因为不是每个人都需要或买的起最好的钢琴。
每种类型的钢琴可以进一步细分为两组，共计四组。1、3组代表两种类型中质量最好的钢琴，2、4组代表每一类型中质量稍微差一些的钢琴，但成本要低一些，结果经常是一种更好的价值体现。所以如果你冲着质量买的话，一般你可以查1、3组。如果你想物有所值，你可以查2、4组。
在这本书中，我把这四组中的每一组又分为几小组，每一小组包括一个或多个品牌（基本一样），品牌以字母顺序进行排列。重要的是，两个品牌排在一起，并不说明它们的特点相似。例如，一个品牌音乐设计很好，但质量控制有问题；另一个品牌设计一般，但质量控制很好。虽然不一样，但通过平衡，最终它们可能基本是等同的。当然，这取决于音乐设计与质量控制对你来说哪个更重要。
第一组：最高质量的演奏级钢琴
这组琴的目标客户是想要最好的质量又能买的起的人。它们用最好的材料，生产过程强调手工劳动和细节的精细化。它们不辞辛劳地执行先进的设计，对于质量的考虑要远远地在成本和产量之前。它们非常适用于高级的、要求苛刻的专业化、艺术化场合。这一组中的大多数琴在美国和西欧制造。
立式琴：14,000—34,000美元

对第一组的评述：在本等级划分体系中，对1A组比其它组更容易达成共识。这一组的钢琴如此有名，以至于经销商都渴望指定此清单中的制造商作为竞争对手。这些琴什么都有，对细节的关注简直可以称为疯狂。这一组中的有些牌子众所周知，但不是Steingraeger & S?hne。我知道这个牌子，但对于有如此多的人甚至对它了解不深的人毫不犹豫的指定要它我有些吃惊。注意，汉堡的斯坦威通常在北美是拿不到货的，我把它包括进去目的只是为了提供信息。
1B组中的琴也非常好，但对于它们仅次于1A组中的琴稍微有点争议，可能是因为它们的工艺不如1A组的挑剔，或者它的音乐设计稍差一些，或者两者都有。不过，第一组中偏爱哪种琴主要取决于音乐品位，1B组中的品牌无疑也致力于此。Sauter萨德琴，第一组中新入选的琴，加工的非常漂亮，声音非常好，但其公司在美国非常低调，其音调不象其它琴一样具有纯粹的欧洲风格，所以很容易被忽略。
对于1C组来说，卡瓦依Shigeru，第一组中另一个新入选的琴，是来自日本的达到这一级别的第一个品牌。它开始作为一个当今比较好的钢琴而被大学和其它机构所接受。我仍然不能确定它该归在第一组哪一分组中，所以我暂把它放在1C组中。

斯坦威（纽约），在第一组中是具有最精美声音的钢琴之一－相对于同组其它琴，其做工最差。这一古老品牌有其精妙设计，发音体结构整体性好，是其传统精华所在，做工上有精巧之处，弹、听起来仍然很好。它们也会变化，但如果你不怕麻烦销售人员，让他们派技术人员来调整，你会发现有些确实很好。
我不是太熟、不能准确定位但又可能排在第一组的钢琴是Feurich(弗犹瑞驰)
第二组：高性能钢琴
这些钢琴在高性能的设计特点、材料、工艺方面都按照一定标准制造。它们适用于家庭、机构和某些专业性、艺术性场合。虽然不如第一组钢琴投入的精力多，但在制造过程中也投入了大量的手工劳动，使触感和音调、音色方面更为精细。对于成本，第一组的钢琴实际上不考虑，但在一定（有限）程度上可能会影响到第二组关于材料、生产方法方面的决策。由于多种原因，这些琴所收到的关注不如第一组。虽然这两组之间的质量区别是很小的，对于许多买主来说也是觉察不到的，但价格上的差异却很大，使得这些琴对于那些买的起“几乎是最好的琴”的人来说，确实物有所值。这一组的钢琴大多数是在美国、东欧、西欧制造。
立式琴：6，000美元—20，000美元
三角琴：18，000美元－50，000美元

对第二组的评述：2A组包括三个品牌，非常接近于第一组。Estonia最初位于第二组的底层，在过去的五年中进步如此直快，可能会归于第一组。但是，这一点还没有被接受和确认，所以我把它放在第二组。
我过去总是认为西蒙加工完美，也不是太昂贵，只是缺少一些内在的灵魂。很明显，西蒙先生想给后代留下什么，所以在他退休以前，他全力以赴，采用公司的工艺和技巧生产出了更为先进和成熟的钢琴。他所作出的创新性的设计决策与严格执行工艺（众所周知），把公司的钢琴提高到了一个新的档次。
Mason & Hamlin已经降到2A组中，它仍然是好琴，但我相信公司目前的生产方法更符合第二组，而不是第一组。
我发现很难进一步对第二组进行细分。通过多方联系，对如何细分也很难达成一致。我认为2B组只是稍微比2C组多一些精巧之处。2B组的每个牌子都不一样，我很难想到一种可靠方法对其进行细分。不要被2C组处于第二组的底层所迷惑，它们仍然是好琴，有些甚至是钢琴界中具有最好价值的品牌。
鲍德温三角琴是个特例。我把它们放在这里，是出于尊敬，是由于它们的美好设计、工艺和它们以前的声誉。但它们目前并不是与它们的声誉相一致（盛名之下，其实难负），所以在购买前应该仔细检查。
第三组：较高级别消费型钢琴
这些钢琴对经济性和性能的重视程度基本上是平分秋色。在这一组中占控制地位的是日本公司在日本、美国和印尼生产的钢琴。它们是大批量生产的，但也对细节进行关注，它们一致性较强，基本上一样，只有少数缺陷，适用于家庭和机构。数十年来，由于高的质量控制标准和致力于良好的保修服务，使其具有传奇色彩。在这一组中，也有韩国公司在韩国或印尼生产的较高水平的钢琴，质量多有变动，但通过一些先进的设计来加以巩固提高。

对第3组的评述：3A组大多数由日本公司雅马哈、卡瓦依和韩国英昌、三益制造的最好水平的钢琴组成。后者设计先进，经过技术人员专业化地处理以后，其演奏效果可以与更好级别的钢琴相媲美。但是，其质量易变动，多数经销商只有经过足够的调整以后才能使它们达到可以接受的程度。在这一级别的钢琴中，还包括博斯纳立式琴，目前唯一的中国制造的、从第四组中脱离出来的钢琴。它们具有很好的音色音质和击弦机，经过足够长的时间没有出什么问题，使之在钢琴界脱颖而出，对我来说，我很乐意推荐它们。
3B组由卡瓦依和雅马哈的小型三角琴（具有更为简化的琴壳结构和特色）、韩国英昌产的中档琴、三益产的中、高档琴（在韩国或印尼制造）。我也把美国产的鲍德温归在这一组中，但真诚地来讲，鲍德温近来处于较低的层次上，关于它的立式琴的反馈很少。
3C组主要是三益在印尼或韩国产的中档琴（Kohler和 Campbell Millennium）及全部在印尼生产的高档琴（J.Pramberger）。在3A组中对韩国琴所作的评述同样适用于3B、3C中韩国和印尼生产的钢琴。
第四组：中级消费型钢琴
这组琴中的大多数对于经济性的考虑要稍重于性能。通常来说， 质量控制也不如第三组的完善，所以在售前售后这些琴需要经销商的关注要多一些。对于一些中国的高档琴来说，质量控制和其特点可能会使钢琴有可能进入更高档次的一组，但它们的跟踪记录很短，所以作为预防措施，我暂时把它们归在这一组。至少，这些琴适用于普通家庭和某些机构用，有时会适用于更多场合。用这些品牌中的小琴学习的学生可能会希望在许多年以后换成大的或更好的琴。这一组中的琴在中国或韩国公司在印尼生产制造。

对第四组的评述：第四组的许多钢琴品牌是新牌子，或者是提高迅速的品牌。我曾尽我的最大努力对它们相对的质量排名进行评估，慎之又慎，而不是夸大它们的质量。我预计将来会发生一些变化。
4A组由最好的中国钢琴组成。它们中的一些具有更高级别钢琴的一些演奏特点，例如象3A中的博斯纳立式琴，可能是由于它们的跟踪记录和声誉保证最终使其排名上升。这一小组中的钢琴由于在设计、材料和工艺执行的结合上做的较好而使其与以下几个小组的琴显著不同，它们中许多采用欧洲或北美进口的部件和材料。例如，据说西蒙曾拒收它所收到的一些May Berlin钢琴，因为它们没有达到公司的硬性标准，把它们退回到了它们的原产地。然后，在把琴发给经销商以前，他们整理剩余的钢琴，使之达到更高的标准。跟我有联系的人通常对给这些琴作一些赞扬比较谨慎，意识到它们物有所值，但又还没准备放弃更好的价格更贵的世界其它地方生产的琴。
4B组由东北三角琴组成，在美国由多家经销商用不同的牌子进行销售。这些琴不如4A组中的琴精巧，但由于设计出色，而使其与其它中国产三角琴显著不同。经过经销商适当处理，它们弹奏起来非常好。注意，Nordiska诺第斯卡与其它的品牌不一样，虽然经销商对不一样的程度有争议。Story & Clark品牌在美国发给经销商以前，代理商要经过调整。Weinbach是东北三角琴的一种高档琴，采用派绰夫键盘和击弦机。虽然它与其它的东北钢琴编在一组，但它可能属于4A组。
4C组:由英昌、珠江、海伦、AXL的大中型中国产钢琴和印尼产的三益低档琴组成。这些琴不大可能因特殊原因而获得赞誉，但经过经销商的适当处理和上门服务，对于非正式的家庭用途还是很好的，有时可能会有更多用途。

For generations, Hobart M. Cable pianos have been bringing music into homes around the country. The Hobart M. Cable piano line has taken great pride in providing fine quality home pianos at a very modest and affordable price.  Most entry-level pianos have a laminated or veneered sounding board along with Chinese hammer felt.  The Hobart M. Cable pianos all have solid Alaskan Sitka spruce soundboards and Japanese hammer felt.  Hobart M. Cable pianos are by far the very best entry-level pianos on the market. They are backed and sold directly by the subsidiary of one of Korea’s strongest multi-national companies. Today’s Hobart M. Cable pianos have preserved the spirit of what made a Hobart M. Cable so popular that nearly 100,000 pianos carry the Hobart M. Cable name in living rooms everywhere. *

From the Blue Book of Pianos

Hobart M. Cable was established in 1900 in LaPorte, IN and was built in the United States for over 65 years. The "Cable" name, and more significantly, Hobart M. Cable has always been recognized as an American standard and an American favorite name brand. America Sejung Corp. has been meticulous and diligent to again make available to North America an instrument that perpetuates this heritage.

The distinctive characteristics of the piano are remarkably sweet and pure tone qualities combined with unusual power. The construction of the piano is notable for its solidity and compactness and for a number of superior features, which contribute to the general excellence. The scale, which is the scientific basis of quality in the Hobart M. Cable piano, is of the even, unbroken and satisfying kind that appeals to the trained musical ear. It is the inner secret of the great growth of the Hobart M. Cable piano' s frame. In a word, it may be said that the Hobart M. Cable piano is a remarkable instrument, possessing all of the essentials of a strictly high-grade piano.

The Gulbransen Company was established in 1904 by Axel Gulbransen in Chicago, Illinois. By 1917, Gulbransen had become the largest manufacturer of player pianos in the world. The Gulbransen Registering Piano was unquestionably one of the best-known instruments of its class. Its trademark, Easy-at-the-Pedals, and slogan, "Easy to Play," were impressed upon the memory of millions of people through national advertising.

In 1928, Gulbransen introduced their first organ, which later would become a major focus for the company. In 1962 Gulbransen introduced the world's first transistor organ and by 1988 Gulbransen had amassed many technological "firsts" in the music industry, and started designing digital pianos for foreign manufacturers.

The great favor with which Gulbransen instruments have been regarded over the years by music loving people of discriminating judgment is the best possible proof of their merits. During World War II, along with Steinway, Gulbransen pianos had the distinction of being selected as one of only two manufacturers of pianos for government use. Today you can find Gulbransen pianos in select outlets. For more information

Why Wyman - Here's Why!

Beauty of Appearance
Wyman vertical pianos come in an exciting array of quality styles and finishes to meet every need, from practical designs and small entry-level instruments to larger professional studio upright models. The Wyman polished finishes are as durable as they are beautiful, adding beauty and style to any décor. The new Wyman American Designer Collection models feature beautiful satin finishes in popular sizes and designs for today's casual American lifestyle.

Wyman grand pianos offer classic grand piano styling in a number of popular colors and finishes. The traditional shape of the modern grand piano instantly conveys a sense of timeless elegance. The durable burnished finish is easy to care for and will maintain its beauty for a lifetime. Grand pianos are classic in shape and unique in their character, and these beautiful instruments will add much to surrounding décor. Wyman grand pianos speak elegance in a very eloquent way!

Musical Performance
The exclusive Wyman TriPhonic? soundboard utilizes three layers of fine spruce whose grains are positioned at prescribed angles for optimum tone projection and durability. Wyman treble bridges are constructed of hard rock maple and efficiently transmit the string vibrations directly to the soundboard. The spruce ribs mounted on the rear of the soundboard are notched into the liner, providing additional strength and support to maintain the precise crown of the soundboard, as well as distributing string vibrations across the most vibrant part of the soundboard for optimum musical tone projection.

Wyman grand pianos feature the exclusive Wyman TriPhonic? cantilevered bass bridge. The cantilever design allows bass string vibrations to be transferred to a more vibrant area of the soundboard away from the liner. In addition, the Wyman TriPhonic? bass bridge apron and runner are cut into three separate and distinct sections allowing for maximum sound transmission and bass response.

Wyman instruments feature treble strings made from the finest high-grade Roslau music wire from Germany, providing clear, bell-like piano tone in the treble. Wyman bass strings are wound with solid copper windings to provide deep, rich bass tone characteristic of larger instruments.

Wyman pianos feature premium Yumei hammers that are made from fine 100% virgin wool and are individually wire stapled to maintain their precise shape. This assures consistently beautiful piano tone across the full range of the keyboard, ensuring years of musical pleasure for the player as well as the listener.

Wyman pianos also feature premium Yumei piano actions that are constructed from premium quality hard rock maple, a fine quality wood that is very dense, hard and durable - the same natural material used in pianos that cost several times the cost of your new Wyman piano. Hard rock maple provides the dimensional stability needed to keep your new piano action playing smoothly and freely for a lifetime of trouble-free musical enjoyment.

Durability Features
All Wyman instruments utilize a select seasoned spruce key design for strength and durability that will not warp or twist to cause problems that develop in lesser quality brands. Wyman key tops are made from a durable white acrylic resin material that will not yellow or otherwise discolor. The "smile" of your Wyman piano will always be the same bright white color as the day it was delivered to your home!

The smooth heavy metal plate used in the Wyman piano is made from gray cast iron using a meticulous sand casting process. This process creates a very thick and durable plate that is essential for tuning stability. The sand cast Wyman plate is musically inert and does not interfere with the musical performance of the piano.

The 19-ply Wyman wrestplank is constructed from hard rock maple, the finest material available. The grain orientation of each wrestplank ply is placed at prescribed angles to hold each tuning pin firmly. Wyman tuning pins are thread cut and chromium plated for durability as well as an attractive appearance.

The 19-ply Wyman wrestplank, the thick and sturdy Wyman sand cast iron plate, and the wooden back frame all work together to provide outstanding tuning stability over the life of your Wyman piano. Tuning stability translates into added musical enjoyment from a better sounding piano.

Wyman instruments feature pedals made from solid cast brass. Solid brass will maintain its beauty over the life of the piano: no unsightly "wear throughs" with use over time. All Wyman vertical pianos feature a mute rail for softer play during practice.

Wyman Tradition
Wyman instruments continue a long tradition of piano making, incorporating proven German scale designs with popular Continental, Classic and American furniture styling second to none. Only the finest materials, natural wood products and veneers are used to construct today's quality Wyman Pianoforte instruments. Wyman's experienced team with over 90 years of piano industry experience is committed to superior customer care and satisfaction, a Wyman tradition.

The musical scale of the Wyman piano is defined as the sum of all parts that contribute to the musical performance of the piano. Because Wyman pianos only use the world's finest materials, the result is an exquisite instrument of uncommon quality and value, an instrument that will provide enduring beauty and musical enjoyment for you and your family for many years to come!

History of the Henry F. Miller Piano
Birth of An American Classic
 

Boston, 1863. A classically trained musician named Henry F. Miller joins expert designer J.H. Gibson in founding a new piano company. Miller had worked for seven years at another piano maker, learning his craft. But as a performer, who had earned a reputation at the keyboard, he knew he could create a piano with the dynamics and aesthetics an artist could love.

Miller and Gibson's new instruments were such a success that Miller's fice sons were brought into the business. Under the leadership of Henry F. Miller, Jr., they improved and refined their pianos, and by the turn of the century, many virtuoso performers demanded Miller & Sons pianos for their concert work.

Built on a Solid Foundation
The Henry F. Miller plant, as it appeared in 1898, was typical of the industrial architecture of the day. Factories were built within cities to ensure a large labor pool. However, the space restrictions of most cities necessitated multi-story factories.

An Enduring Legacy
Over the next century and into the present, Henry F. Miller pianos have continued to be valued for their character as instruments and for the distinction of their design.

The Henry F. Miller commitment to excellence has been indisputable for over 135 years. Only the finest hardwoods and other materials are selected and delivered into the hands of skilled craftspeople. Their attention to detail and scrupulous quality control insure the instrument you select will last for generations.

The History of Story & Clark Pianos

Since 1857, when Hampton L. Story built his first piano, discriminating purchasers have marveled at the fine

craftsmanship that makes every Story & Clark piano a treasure. Exacting standards for tonal excellence and quality

at a superb overall value are the hallmarks of Story & Clark pianos.

Today's Story & Clark pianos reflect the company's rich and unique American history of over a century of innovation

combined with expert craftsmanship in piano-making. Melville Clark is generally credited with creating the first

player piano as we know it today (the Apollo). The company went on to develop the first electric piano (in

partnership with RCA in 1939) and today they continue the tradition with PNOscan?.

Beginning in 2008, each Story & Clark piano and player piano now comes standard with PNOscan, a state-of-the-art

MIDI optical sensor strip invisibly installed under the keys, as well as discretely placed USB and MIDI ports. These

innovations do not interfere with the touch, response or beauty of the piano in any way and yet open up a world of

possibilities through connectivity.

Today, there is nothing you can do with a digital piano that you can't do with a Story & Clark acoustic piano with

the proper accessories. In fact, the potential of Story & Clark acoustic pianos exceeds that of any digital piano,

yet does not have the major drawback of most technology: obsolescence. Via the PNOscan? MIDI strip and MIDI ports,

Story & Clark pianos give you the ability to connect with new MIDI devices, personal computers and the Internet and

take advantage of new technology as it develops. Whether you want to learn to play the piano or are an accomplished

professional musician, Story & Clark pianos and player pianos are designed to meet your needs.

But the real beauty of a Story & Clark acoustic piano? All of these extra features are virtually invisible; they are

there if you want to use them, but if you just want to enjoy the sound and beauty of a classic acoustic piano, you

never have to know they're there.

QRS Pianomation 钢琴自动演奏系统

QRS was founded in 1900 by Melville Clark (of Story & Clark piano fame) who developed the player piano as we know it

today. QRS supplied music rolls to the player piano market, with production peaking in 1927, when QRS Music Company

sold 10 million rolls.

The player piano''s heyday lasted from 1900 until the Great Depression in the 1930s. The poverty of the Great

Depression, along with the development of affordable radios (which started becoming commonplace around 1927)

effectively ended player piano production. However, the demand for rolls continued and was reinvigorated in the

1950s when people began restoring old player pianos. QRS remains the only manufacturer of piano rolls in the world

today. To view a video on how QRS piano rolls are made, click here.

In 1986, QRS began focusing on new technologies, and in 1989 released its first digital retrofit player piano kit

under the Pianomation name. Today QRS is an industry leader in introducing fun innovations in home musical

entertainment. QRS Music Technologies became a public company in 1996.
