I have an upright sfortunately and I can't afford a grand at this moment as I am still a student.

But with the upright, does it affect some fast scale (or fast octaves chromatics) passages?
I mean, notes which are to be played very fast , with an upright, can be not heard clearly?

Thanks as always

what brand and HOW OLD??? whats the condition is like?

i have a hyundai. it is old for about 12 yrs

My experience with uprights, with few exceptions, is that yes they have a slower action. I think it must have something to do with the fact that the hammers are striking horizontally instead of vertically, which means more parts must move, plus gravity is not helping the hammers get back into starting position as easily. I dunno.

Same opinion as Joshua. I fint it toos easier to play on a grand, especially fast passages. Also the dynamics can be controlled better.

The question is however, whether it is good or bad to practise on an upright. Maybe it has the advantage that it feels easier to play on a grand this way. I have a grand to practise, and always find it difficult to get adapted to the Upright action, especially regarding dynamic control, but too for fast passages.

Additional, I believe that most of the Uprigths don't have (but Grands have usually) double repetition mechanics what eases fast repetitions, also trills on a grand much.

Yes, grands use gravity for quicker response.

I heard it from somewhere that you can only hit the same key about 7 times per second on Upright Pianos but about 14 times on Grand Piano.
So I guess Grand Piano is better for fast passages and especiall trills.

Hi,
I'm a technician for Bösendorfer, and I must disagree with these oppinions, an upright action can be just as responsive as a grand. If the piano is very expencive and high quality, and regulation is done right initially, it will be just as responcive. As for sound, that depends on who likes what, I myself own a Bösendorfer Flügel (Imperial model) which I'm quite happy with, as well as an upright piano manufactured in Ukraine, both satisfy me on same level. However the Faziolli which i recently disposed off, was awful, sound was rich and deep, but very hard to control....

I want a Bösendorfer!

eve-ane,
I love a Bosendorfer. We had one in our practice rooms in Austria and all the piano students would compete to practice on it. I loved it for its mellow tone which made it great for Chopin and Mozart, to get the delicate sounds. I heard that since the company was under new management however, it isn't made in the same way and doesn't have as much of the mellow sound. Is that true?

I agree that not all uprights are not lousy, or not so responsive.
My teacher said that if you can afford an expensive piano but can't fit a grand in, get a Petrof upright (highest quality)

Grand Piano's are a lot better for fast passages. Playing pieces like Hungarian Rhapsody 6 is impossible on some upright piano's, because they're way too slow. I've also had some trouble playing trills on uprights, because... well.. they're way too slow!
However, it really depends on the brand and the condition the piano is in. So far, I've only seen ( and played on ) one upright that was in a perfect condition and that wasn't really slow.
