    Hello! I’m posting to see if I can get any help understanding harp finish:D

    When you purchase a harp, I figure you need to choose what finish you’d want it to be, mohogany, cherry, natural, black, white, blue, etc. I have never stained wood before and I’m not sure if a finish on harp affects the durability or sound of the instrument. I hope it doesn’t, but I know absolutely nothing.

    Does anybody know whether the finish affect the instrument? If so, how?

    And,

    If you like a certain finish, I’d like to know your reason why:)

    Also,

    Which finish can make the grain of wood come out more? Natural, maybe? (I’m sorry if this doesn’t make sense.)

    Thank you in advance!

    First, there is the wood the harp is made of- that wood be something like walnut or cherry or mahogany or spruce.

    Then there is the finish- It could also be the name of the wood if it were, say ,spruce and being stained to look like another wood- not that common though- especially the better the harp.

    It might also be painted or clear coated. Generally, an unfinished harp is going to deliver the best volume and resonance and sustain longer. Top coating materials add mass and density that kills the natural vibrations, yet this is a nebulous affair and good harp makers know what they are doing.

    Finishes, paint or clearcoating can add strength to the harp where it needs it- the frame- the top, the pillar without having much effect on the sound. The sound box is more sensitive and the best sound is when it is lightweight and not heavily weighted by a finish.

    Hope that helps.

    Let’s first of all distinguish between stains and finishes. A stain simply colors the wood, a finish is a hard coating to protect it. The maker may offer you a choice on stains but will usually apply the finish they prefer. Of course if you make the harp yourself choose what you prefer.

    The most common finishes are lacquer, rubbed oil, and polyurethane varnish. Lacquer dries fast, is very hard and high gloss but the fumes are toxic. A rubbed oil such as Tru-oil also dries quickly and is easy to fix if you missed a scratch from sanding. Polyurethanes are a good choice if you are not into finishing (an art in itself) but may dull the tone if used on a solid wood sound board. Polys come in gloss, semi-gloss and satin; they are also available as gels and may incorporate a stain as well.

    Some harp makers offer a choice on stains (if any) but most if not all will use the finish that they prefer. The finish provides very little if any additional strength unless it is applied in many heavy coats, which is obviously not what you want on the sound board.

    Ooops sorry, I forgot to answer what I personally prefer as(a lever harp) maker and why.

    For the frame and box I will first of all be very selective in choosing the wood – for figure, close grain etc. – which will save me a lot of time in sanding as well a look good. Since I really like to see the wood grain and figure I do not stain it and for the finish rub on Tru-Oil Gunstock finish.

    Early on I used Min-wax polyurethane and will still use it for an inexpensive harp built out of baltic birch ply (which I might also stain.

    I like Tru-oil because it gives the degree of sheen I like, depending on how many coats I use, dries quickly and does not drip (much haha). Some dedicated finishers will use shellac but that takes a lot of elbow grease an does not protect against water stain if the harp happens to get wet.

    For the sound board I will almost always use lacquer unless it is a Finnish ply board (3 to 5 veneers per 1/8 in/3mm). I want as little as possible to interfere with the board’s vibration assuming a spruce or other soft wood; with the ply board it does not make much difference since those will not stretch and achieve more color over time.

    The best way to bring out the grain is very careful sanding with graded grits, followed by scraping to eliminate each and every blemish. Scraping will also add microscopic “dust” into wood pores; that is the principle used with shellac sand-rubbed finish.

    Over the centuries wood workers have used a variety of methods to make the grain “pop” (heating, acids, etc.) but that’s a whole other discussion on a wood worker’s forum.

    Thanks, Biagio, for all that wonderful info! You do such a nice job on all those harps you build.

    Nicbo, I will try to answer this in regard to the Camac Egerie harp finish choices. I prefer the Natural Maple, since it shows up the high quality of the wood that Camac uses in their harps. In my Atlantide, it is “curly maple,” or “tiger maple,” and is CHOICE wood, extremely beautiful. Maple is used where it shows, and beech is used for strength, like in the neck and body of the harp. Where the wood is laminated together, usually in beech, there is always a layer of choice maple on the outside, and many of the harp’s parts are actually solid maple, carved to perfection. The soundboard is spruce, there again, made of aged wood which has a profound and very resonant tone.

    You may prefer the other finishes, and I particularly like the black–it is very elegant! My first Lyon and Healy pedal harp was black, and I cannot really tell whether any of these different finishes affects the tone very much. To each his own, I always say–much of it is a matter of personal taste.

    I hope this helps. Others here will have their own personal preferences, of course–that is why there are so many choices in harps out there!

    Cheers and best wishes,
    Balfour (and Carol Lynn)

    Hi Biagio!
    All what you have written above is not anything i can find anywhere online, wow! You must be a harp maker! (Probably a builder that everyone in this forum knows about! I’m still trying to get to know people well…)

    Do you sell your own harps? Or have a company? I’d like to visit your website and see your art work.

    Thank you for sharing your knowledge Biagio!

    I finally found out how to respond to one person instead of the entire group! Hooray!

    Balfour, I just came back from the store today. The lady showed me the different finishes and I narrowed it down to natural and Walmart. I knew I wanted to be able to see the grain so I eliminated the colors that would hide the grain. (Like ebony.) She showed me her harp which was light Walnut and it was very pretty, I had to add that to my option! I haven’t decided yet, but I’ll have to tell her soon before she places the order. I’m going to do lot of image search tonight and hopefully I can make up my mind!

    Oh the natural finish Atlantide must be so gorgeous.. thank you for letting me know that the choice of stain will not affect the sound. I’m glad I asked!

    Have a good night!

    Hi Nicbo and thank you Balfour,

    All that stuff about stains and finish: it’s information you would find most likely in a wood working site or books. Harp makers would rather talk about how their instruments sound, not surprisingly!

    I started making musical instruments just for fun and to pass the time during winter when living in a cabin in the Blue Ridge mountains, as many do there: usually fiddles, banjos dulcimers etc. Then one day tried a harp and got hooked and started doing them for myself and for friends and acquaintances. At one time considered doing it full time but age and health dissuaded me LOL. But the craft still fascinates me so I know a lot of harp makers – they are among the nicest and most generous people you would ever want to meet!

    So glad to help, Nicbo. Yes, the natural finish on my Atlantide is gorgeous. It is satin instead of high gloss, which really shows up the beautiful curly maple grain of the wood. I know your new Egerie will be just wonderful–we are so excited for you!

    New harp hugs,
    Balfour and Carol Lynn

    Hi Nicbo!

    Did you ever decide on the finish? It is so exciting to order a new harp!

    Best to you,
    Balfour

    If you’re buying a Lyon & Healy harp, a natural finish generally means the best-looking, best-matched wood, as there is no coloring. They are very white at first, but age into a beautiful blond color. I went with a walnut harp at first, but it faded into a lovely more-mahogany color. A natural finish harp looks best on stage. Ebony affects the sound, and I suspect any other coloring will, as well.
