techniques for voicing Mason & Hamlin

  • 1.  techniques for voicing Mason & Hamlin

    Posted 05-09-2024 18:03

    I have a new client that has a +/- 5 year old 6'2" Mason and Hamlin.  I have no experience voicing Mason and Hamlin pianos.  I primarily deal with Baldwin and Yamaha's with a smattering of Steinway's and Kawai's. The client is in need of some voicing.  The piano isn't bright (except the top 2 octaves, but she likes that part so I won't be really touching those) but the piano is very nasal.  The potential to sound great is there but everything just cuts off/chokes out too soon and sounds like it has a cold or something.

    Anyone have some pointers on how to deal with this issue?  Is there anything special about Mason and Hamlin hammers that I should be aware of?

    Obviously, I will deal with all the regulation needs to create a good foundation to build upon.  I would just like some pointers on how to tackle the voicing.  

    Many thanks in advanced.

    Assuming that regulation is up to spec and let-off is not blocking tone production,  start by deep needling or squeezing the high shoulders.  Go for

    decay and power.  Of course hammers need to be well fitted to the strings. You may find "Working With Hammers" by Wally Brooks useful,

    Hi Barbara, I suggest you reach out to Boaz Kirshenbaum (pianotuner@gmail.com). A few months ago he had to cut his schedule back radically  due to a flareup with tendonitis, so he may have time available to coach you through this voicing job. Among his various tech gigs he did work for M&H in their voicing department.

    For a nasal tone, I would check & correct hammer to string mating first.  We should always check that of course, but especially in this case.  It also wouldn't hurt to pluck several strings with the individual damper lifted, to make sure the sustain isn't getting choked off by something _else_.

    My experience with the latest M&H hammers is limited to a recent set of the WNG Natural Hammers.  I don't know if the piano in question has those.  But my set definitely responded well to deep needling in the 9-10 o'clock range, and a bit shallower going up toward the strike point.  YMMV.

    I concur with Mr. Monteleone here. Deep needling in that area (9-10 o'clock) especially on the proximal side (the side closer to the player), giving more heed to the harder shoulder. Of course also being aware of travel and hammer angle which will help with hammer fitting to strings.

    I've also worked on a Mason & Hamlin that sounded nasal and thin and had success by moving the strike point towards the bridge.

    Did you find you had to work pretty hard to get the needles in these at first? I had to start shallow and work my way in a bit.

    A voicing question like that cannot really be answered. Nor can advice on how to correct the voicing issue be accepted. Voicing any brand of piano whether cold pressed hammers or hard pressed hammers is all the same. I suggest learning what ADSR is and the piano envelope shape, and learn how to listen to the piano tone before attempting a fix. A good start for listening is to play each  hammer through its complete dynamic range from very soft to very loud. You'll quickly be able to pick out the one that don't perform like the others. Next listen to each hammers decay and sustain, is the decay quick or slow? BTW most techs confuse decay with sustain, from observing discussions on this and other forums. Listen for quick decay drops to fix. And lastly, play hammers softly and listen to the attack for evenness of bright or mellow. 

    All the Best!

    On the proximal side, yes.

    I agree with the idea that the basic principles of voicing are the same for any hammer. Probably the most important is laying the foundation so that each hammer is focused on its strings. That means starting with meticulous travel and  hammer squaring (vertical on its shank, in line with the arc of travel of the shank), so that the hammer moves directly vertically, no wobble (firm pinning is a prerequisite for this). Then level strings and file hammers so that their profile is correct and so that the crowns are perfectly square to the vertical travel of the shank. Touch up mating as needed.

    No shortcuts. Simply do it as a matter of course. Until you have done this work, any "voicing" you do is lipstick on a pig, because you haven't addressed what is fundamentally important: unison strings that are impacted simultaneously. If there isn't simultaneity, there will be out of phase vibrations, and they will be chaotic, varying from unison to unison and within a unison depending on the strength of the blow. There will also be extraneous tonal components, including nasal sounds, zingy sounds, dead sounds, etc. 

    Once this foundation is laid, you have focus of tone and can proceed to needle, in order to expand the range of timbre.. In my experience, deep shoulder needling is essential (in softer pressed hammers as well as harder pressed). I prefer the pattern of needle insertion depicted in the attached photo, which is somewhat unconventional but has worked very well for me in hundreds of sets of hammers. The lines are 10 mm long. That is generally my minimum needle length for most of the piano (I often use 11 - 12 mm), tapering in the the top three octaves. 

    Conventional diagrams show needles inserted radially, aimed from the surface directly to the core. I find that pattern is impossible to achieve more often than not, particularly with denser hammers. You are trying to penetrate an ever increasing density of felt fibers. When you start at the mid shoulder and aim to penetrate more or less parallel to the outer surface of the felt insertion is far easier. The first insertion opens up the outer felt, providing space for the next, parallel  insertion - somewhere for the felt to go, and this is progressive.  (If the felt is too dense for this, I use two needles instead of three, making two side by side lines up the surface of the hammer. In extreme cases I use one needle).

    Moving up the shoulder toward the crown, the angle is changed gradually, until at the very top it is aimed outward,  leaving a pointed area of felt above the tip of the molding untouched. The pattern of opening the felt is the same as in most conventional drawings, but is achieved differently and more easily.

    I simply do this pattern to every hammer, whether lacquered or not. The results are a broad range of timbral color that will need minimal touch up to even things out. Most of the touch up is quite near the middle of the crown.

    I assume that you reset the hammer after needling.

    Thanks for the very useful visual. I was not going anywhere near that far down on the shoulder, and I need to try it. You are right that most of the diagrams scared me into not poking diagonally down into that area.

    When I first started doing serious hammer needling, I did what I had seen: stab at the hammers with 5 mm needles, generally aiming toward the molding. The results were disappointing. I could get the hammers to sound "less bad," but they would never really develop a range of color.

    I had seen illustrations of needle tools with what I thought were impossibly long needles. I observed and asked, and found some technicians who absolutely swore by 10 mm or more, as well as seeing the Bosendorfer tech director using needles that long.

    So I experimented to see if I could be successful in inserting needles that deeply. The first success came with standing over the well supported hammers and pressing the needles in. That worked well with moderately dense felt, but wasn't possible with extra dense (like Renner blues). The second success came from experimenting with angles of insertion. I got the idea of layering: opening up a layer at a time, from the outside in, and gradually changing the angle of insertion. 

    And the results were astonishingly better than my 5 mm needling efforts. Depth made all the difference, together with leaving an acute angle of untouched felt over the tip of the molding.

    I haven't seen or heard of anyone else advocating for such a procedure, so I have gradually tried to insert it (pun intended) into the conversation, beginning with my account of voicing technique in Thing the Upright Piano Seriously. I hope it is helpful.

    Excellent summary. I was taught similarly using that technique to get deeper which indeed makes a bigger and more lasting difference.

    Greetings, 
       I remember hearing at NBSS that there were European techs (perhaps one of the Glazebrooks?) that would pre-voice Renner hammers for the Hamburg pianos on the bench before hanging them.  This allowed them to hammer the needles straight towards the molding down at the 9:00 and 3:00 positions, (or lower), and gradually increase the angle as they came up towards the crown.    I have done a number of sets like that and it works well to begin the resilience chase.  I ever do this on the Ronsen's that I have come to favor and it saves a lot of work in comparison to beginning after the hammers are hung.  I think it saves wear and tear on the shank, pinning, and glue joint. 
    Regards,

    I have seen videos, I think from Renner USA, of pre voicing before hanging, hammers held in a clamp. That is a reasonable procedure if you are replacing parts, but most of the time I am dealing with hammers that are already hung. For a grand, I support all the hammers above the tops of the back checks via a sturdy piece of angle iron suspended from one end to the keyboard to the other.

    This enables me to do deep needle voicing at the bench, standing over and pressing the needles into the felt (aided by body weight) while not impacting shanks, glue joints or pinning. The pictured 3/4" x 3/4" angle iron is doubled in order to span such a length. More robust angle iron can be used without doubling.

    I like the idea of the angle iron supports on the outside of the action.
