I would ask the dealer to rectify this at no charge to you. Dampers should begin lifting when hammer is approximately 1/2 way to the string.

I read all of them carefully, and last evening I did some checkings in order to share them with you. I want to give you more antecedents and what I found out : - Damper and hammer lift at the same time. - I don't have gram weights at home, but my wife has a digital kitchen scale. So I can know in a very accurately way the weight o different objects. I checked the 'typical' weight to push down a key (50 g), using a 56g object (with the sustain pedal depressed) and only a few keys traveled down a little (1/3 cm), the others didn't travel at all. - Before the C1 I had a C108 (Yamaha upright). The action wasn't 'light', but now I don't remember it was so 'heavy' as the C1. I played in the past other Yamaha grands (C7, CFIIIS, GH1) and I don't remember they had 'heavy' touch. At my piano school we had a Bösendorfer, and it was OK for me. Now I have a Yamaha digital piano P200, at home, in which I study late at night, it has a very light touch. Maybe it's confusing me... - I find the keyboard action is 'heavy' especially in fast passages, I'm now studing Chopin's waltzes # 1 and # 6 (Minute). In other slow pieces the effect is not recognizable. - Keys fall down under their own weight, so I don't think that action centers are too tight. And I have more questions, too : - Since my piano is only 4 months old, why should I ask a technician for : - Revise tightness in key bushings and balance rail hole ? - Cleaning and polishing keypins and capstans ? - Checking centers for excessive friction? Lubricate knuckles ? - Shoul I expect that a new piano (and not the cheapest one) must have all these things working all right ? - It is reasonable to expect that keyboard action in a grand piano must be 'ligther' than an upright piano ? (at similar quality, I mean). - Would be a good deal to adjust the repetition spring tension ? And if I loose repetition speed ? - What does mean 'after touch' ? - Are there notorius differences between actions of different grand pianos ? Should I expect a Steinway is 'ligther' than a Yamaha ? My arms and hands are not strong, and I really feel comfortable with soft mechanisms. Is this a sin ? And a special mention to Robert S. Kuhn, thanks for your advice, I will follow it. Surely I will really appreciate your offer. Don't forget to tell me when it happens ! Best regards, Fernando ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
