Hello all, I feel the need to try my hand at building an round sound box with extended soundboard. I'm open to all and any advice. I have been reading about ...
Charles, You should write Lee Gayman (leezzzz@...). He did two extended soundboards on round backs last year based on the Music Makers Regency design. I...

Hi Folks, I'd be interested to hear people's thoughts on how string angle effects sound. Is any effect more a result of the consequent variation in soundboard ...
Things have been pretty quiet on the list, so I figured it's time for another stupid question! first, the set-up: whereas: Every harp I've seen has a...
Hi all, Over the past two weeks I have strung up eight new harps...five 29-string Studio Harps (from Musicmaker's blueprints) and three Regency's (one from a ...

Hello: I just got the new EMS catalogue and was thinking to by a kit from them... Any feedback from the quality? Cheers Ben [Non-text portions of this message...
Oddly [or maybe not so] I use a bias grain on my small Black Mountain harps but it is more for economy than theory. I use solid quartersawn sycamore for those...
Hi all, This idea of not running the strings down the center of the soundboard intrigues me. I mainly play triple strung harps, and have recently been doing...
Wow! Sycamore soundboard! I just recently had the opportunity to see some sycamore dieboard and marveled at what David termed its "...woven grain and...
Sorry, David- I sent that last missive before getting on your website and reading your disquisition on sycamore - and other woods. A most informative and...
Seb, The real reason for the offset stringband is that it is easier. The complicated descriptions of this method as being chosen for it's "superior sound"...
To answer Dave's questions. The advantages of using solid wood for your sound board is that you can taper the board in any direction you like. I taper on a...
I have to disagree with you here, Craig. I can't speak for any other harp makers who use off-set string ribs, but I do know why I do it. While I freely admit...

Hi There, Thanks for your explanation. But From a players perspective your offseting to the wrong side of the soundbox for ease of playability. I have only...
Hi, Sebastian By a more completely "live" soundboard, I mean primarily a soundboard with even tonal response-- which is to say that no individual note rings...
Yes, Tim, We had a discussion about this some years ago and I remember being impressed with your research at the time. It is a given that any change results in...
Craig is correct in saying that off-setting the string rib will not magically ensure that a harpmaker's product is superb. Soundboard asymmetry is just a...
Hi everyone, I'm trying to get a handle on some basic phenomena and how they relate to harp design, and I'm currently wrestling with this business of sustain....
Also consider the resonance of the box. Resonant coupling will lead to longer sustain. Remember that too much sustain is a bad thing, too. Cheers, Fred ...
I was trying a harp on the Frankfurt Messe and realized something odd: The lower bass strings is realy close from the column, whould it not be better to have...
Suppose, then, that you've decided that a certain soundbox design is too resonant (or not resonant enough), what aspect of its design would you most likely...
Jim, At least in theory, sustain is a pretty straightforeward relationship. A plucked string will vibrate for a long time unless something else absorbs the...
Craig, In practical terms, then, what would be the design or construction elements that would increase or decrease the transmission of energy from the string...
Hiya folks, Here are a few thoughts I've had on the subject that were inspired by the lively discussion. In this discussion as in all discussions of plucked...
Each of the engineering disciplines use a similar set of equations to model a system's behavior. Electrical Engineers can predict the voltage, amperage and...

I'm re-thinking my earlier assumption that sympathetic resonance augments sustain; in light of this discussion, vibration picked up by other strings through...
