So the french technician is trained by Kawai? Good = for you. If he is to see the piano again in the near future, he should = be able to take care of it for you, to your liking. Ironing can make a = difference however slight, it may be enough. We don't use ironing here = in Arizona because it's so dry that we don't really see much of a = difference. If he's a MPA, he'll know about mating strings to the hammer = and all the techniques which should restore the power that you desire. I = was worried that someone who wasn't highly trained got to your piano and = did something which could probably be undone by a qualified technician, = and when I saw the comment on changing hammers, I felt I had to jump in = and bring a stop to such rubbish. I don't think you can even get Shigeru = hammers for a small section, without replacing the whole set. You = certainly wouldn't want any other kind on that piano. "I'll also take care of the keyboard frame level in that range." I was referring to the levelness of the top of the hammer, when at the = position at which they stike the keys, by the way. This is an important prelude to leveling the strings so that each = contacts the hammer in the same way, so that all three strings are "in = phase". Helps with the power, you must know... I hope that I've helped, at least I've stopped something bad from = happening. Please feel free to write back after this is resolved, = perhaps I can learn something here also. Yours,=20 Kevin E.

Actually, the piano was very harsh when coming from Japan. A french = Master Piano Artisan has prepared the piano and I've tried it before = ordering. I've well noticed the need to give more power to these notes = to get more balanced sound, and I've considered this a minor problem. = The MPA told me to play the piano for 6 months and he will improve this = during the visit at my house (MPAs are licensed by Kawai to service = Shigeru's). I'm confident the technician will recover some brightness to these = notes. I'll follow you regarding juicing. I agree that "banging" the = hammers might do the trick. I'll also take care of the keyboard frame = level in that range. The piano tech of my local dealer (familiar with S&S) tells me dry = ironing on the shoulders, not directly on the crown, would anyway = recover a cleaner attack at soft playing. it's likely something that = could be tested, in a conservative way of course. What do you think ? Your remark regarding losing high frequencies is relevant, but I'm = still OK for the moment (still young 40 years old man, isn't it ?). By = the way, I've checked with other pianists playing my piano who are = having the same perception than me. Stephane Hanriat ----- Original Message -----=20 From: Kevin E.

First of all, don't even think of changing the hammers on your = piano. Those hammers are very special, and they are one of the secrets = of why the Shigeru is what it is. If you had a technician file the = hammers, his technique may leave a lot to be desired. With Shigeru's I = always finish off with at least 800 grit, with the hammers set at the = strike point, so that I'm getting an absolutely level strike surface. If = you don't get the strike surface level, you lose power. Unless a = technician who is not familiar with the special techniques used on one = of these happened to over-needle the hammers, they come from the factory = well in the range of where they should be in your home. Only you can = answer as to who may have worked on your piano. I don't want to offend you, but this question sometimes comes = from people who are losing a little of their high frequency hearing, = which is more common today than most people realise. I just mention it = so that you can consider whether that may indeed be a possibility. If = the hammers have been over needled in that area of the scale, usually = they will brighten up when filed properly, and or "reset" with the back = end of a voicing tool, or a small 2 oz. mallet, in a voicing tray. Do = not, nor let your technician, treat these hammers with chemicals. These = are not Steinway hammers, so they don't need the juice, you'll lose your = dynamic range if you do. Have you had a Japanese technician come out to = your house, yet? Explain your concerns to him, and I'm sure he can do = what you want. I read what someone else wrote on the list before I = hastily jumped in here, about them not coming out to the college.. I'm = not sure that they do that for institutions, only individuals perhaps. = I'm sure that Don Mannino is going to jump in here, he's the final = authority, not me. I only posted this to keep you from doing anything = too drastic in the meantime. Kevin E.

Although he disagrees with that, the tone is slightly too mellow = in this range, from pianissimo up to mezzo forte. At pianissimo or piano, the = higher partials are reduced compared to neighboring octaves (impacted notes are from = 55 to 69), and the attack looks a bit dull. Those higher partials are coming back with more strength on the = key. However, these notes always require slightly more strength to produce a = balanced sound. From Mezzo forte up to Forte, things are OK (overall loudness and = tone quality is well balanced) The technician made several filing with very limited improvement. = I'm not a specialist, just a pianist - but my engineering background and = what I learned reading your very interesting posts, tell me that there has been = likely too much deep needling in the higher section of the shoulders. The Shigeru hammers are cold-pressed and are considered as = medim/soft in europe. May be they are not very robust to extensive voicing. I'm wondering what could be the best solution to recover some = power to these 15 hammers : dry ironing, juicing or changing those 15 hammer = heads ? Kawai says the tone will not be even if I change only a sub set of = hammers (they don't want to replace either full set of subset anyway...). Have you experienced changing subset of hammers in this range ? Which hammer head brand would you recommend for those Kawai pianos = (softer than Yamaha...) ? Do you think dry ironing would make it ? (actually the recovery = level I'm expecting is not that big and the felt thickness is small in this range, so = this could work). Many thanks for your feedbacks, Sincerely yours, Stephane Hanriat stephane.hanriat@free.fr PS : This being said, the SK3 is an outstanding instrument. Action = is close to perfection, overall tone is wonderful, rich, not too harsh like = Yamaha and the softer hammers give you great control and margin in the way you = produce louder sound. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
