我眼中最伟大的发明(The Greatest Invention In My Eyes)
Good evening, ladies and gentlemen.
Last night in my room, busy preparing for my speech today, I was puzzled at the opinions of greatest inventions of different persons.
I read many books.
Some articles hold the opinions that the greatest invention in the world is electricity, while the others believe computers cannot be replaced in the modern society.
I read and read, suddenly an idea struck me: The greatest invention are just books.
A famous person has ever said: &Books are the best teachers.& Exactly! That's what I would like to say firstly.
In the long history of human being, books have played an important part in communicating knowledge.
And even today, the situation is still so.
Each year, millions of books are published in the world.
Knowledge changes our lives.
If a learned person wants to express some new idea, probably he will choose to write a book.
On the other hand, the best way to broaden our horizons is reading books.Secondly, as I have been puzzled, books provide you with different ideas.
And you make your decision to choose anyone that fit you.
Or otherwise, you may choose none of them, just like I, instead of obeying books' advise.
I choose &books& as the greatest invention in my eyes.
So, don't you think it's a little interesting? Books are honored as teachers without sound.
But how are books different from our real teachers? I think the fact is that if a real teacher advices me to choose electricity or computer as my topic today, and every one you can imagine, how much brave I will prepare to refuse.
So don't you think books are better tempered and better get along with than our real teachers? That's all, thank you.&

A study in conversation
The compositional economy of this first invention is astounding. Virtually every note of the whole piece is derived from the very short subject, by means of transposition, inversion (turning the subject upside down) or augmentation (lengthening the note values).
The most common version of this invention is the one with semiquavers throughout, but as can be seen in the autograph manuscript, Bach later presented a second version. By adding passing notes to the descending thirds on the second beat, he introduced a triplet motive into the subject.
The two-part inventions are an excellent introduction to contrapuntal music, i.e. music where two or more equally important voices imitate and converse with each other. A subject appears first in one voice and is then echoed in the other voice/voices.
Don?t be led to think that Bach?s inventions are only dry exercises in counterpoint. They were composed to develop the player?s cantabile, i. e. a singing style of playing, and are also very useful to develop one?s coordination, variety of touch and articulation. But above all they are masterful miniatures full of charm and feeling, exploring a wide range of musical expressions.
As you learn each invention, try to locate all the subjects, which might appear transposed.
Practice the inventions hands separately. Try to memorize each hand first, in order to develop independence and touch control. Strive for an even playing. You may want to practice each voice (or each hand) non-legato first. Double check that your fingers are always relaxed before and...

Well it finally happened my wife pushed me into posting something. So here goes . Two Bach inventions both very& easy and yet i have worked my tail off on these.& Three and 1/2 years of study and progress comes by inches and sweat. I wonder if I will ever to be able to really play anything before im 70. Leaves me 7 plus years.& Anyway there played on my brand spanking new Yamaha C7 in my brand spanking new custom studio on the back of my house and recorded on my brand spanking new $7000.00 dollar recording system. At least if my playing isnt very good, my piano and recording equipment& are top notch.& Well without further ado here is what 3 hours a day of constant practice can do for even someone like me.& Any and all corrections would be appreciated. Semper Fi, Roger

Bach two parts Invention nr 1, in C major, isnt the most beautiful of them but I like it very much because of its structure, with its motif variations and development: only in the first seven bars, we have at least 4 invertions and 3 retrogrades, but - this is amazing! - with a overlapping of them: one can ear what one wants. That`s why I like it so much. Now, I`m playing this Invention again trying to play it without any concern of bringing out anything in order that the listener may choose.(All this I learned in Bernhard posts and I dont know how to make him return...I dont say why, because it seems Bernhard doesnt like the word &why&...)But now I have& a question I hope someone may help me: in 13?bar (similar to 5?) there is a e right hand that overlapps the same e left hand: it`s the same key! And I dont know how to play it. For instinct, the first time I learned this Invention, I played a c, after the mordent. But if I do so, I change the structure, because it must be like in 5? bar.Help, please. And thanks (I must apologize for my English...)Rui

I like to play the Inventions for two part and I play all of them. But yesterday, when I was in the forum, I saw some posts about Invention nr 1 where the mordent, at the first bar, was suposed to be played b-c-b. And the same at 2? bar (f-G-f). It happens that I learned this Invention with an old edition of Inventions, by Bruno Mugellini (&& year 1900!), where he says:&in the manuscripts we find a mordent, not a inverted mordent, but this is undoubtedlly an error of the writing&. I dont kow what were his reasons to say this, but I allways have played b-a-b. Am I wrong? Must I play b-c-b? And why Mugellini wrote &undoubtelly an error&. May you help me? Thanks.Rui

I've been playing off and on for years. There are a number of pieces I have learned, on the order of &Anna Magdalena Notebook&, Mozart minuets, etc. I started to learn the first Invention, but it seems like it's taking forever. I'm not having any problem with technique -- the hand independence problems were overcome the first week. I'd say it's more to do with keeping ironclad fingering, and losing my place. I haven't been able to practice a lot each day, maybe 30-45 minutes, but still, it's been more than a month, and I'm still a couple of weeks away, I'd say. Is this piece simply too hard for me? I hope not, because I like it more than anything I've played yet. Contrapuntal music is really fun!Jim

Does anyone have any idea which is the definitive edition of this piece?I have one score which tells me to play at 120bpm, and has minimal ornamentation. I have another which tells me to play at 66bpm. And the recordings vary even more!There is an excellent thread about these pieces, with posts from Bernhard and others. And this has been most helpful, but it didnt answer this question for me.So who do you play this one? What would be a good tempo to play at?My invention作文150字_初中初二作文 - 作文库
