International Appalachian Dulcimer Day


General mountain dulcimer or music discussions

I haven't yet looked at the threads to refresh my memory.  I recall when we were kicking around thoughts, I wanted all FOTMD members to feel welcomed to participate in the day, so advocated for "International".

International Appalachian Dulcimer Day


General mountain dulcimer or music discussions

The conversation started, I think, in January and we launched in March. I made a flyer I think for that year, you can see it on the Positive thread, I tried too post it here but they say the file is too big, funny it wasn’t four years ago.  I probably had to downsize it then too.  The date is on it for that year.

Upon first glance at the positive thread, it seems the conversation started with Dusty suggesting that there ought to be a national dulcimer day, as there is a national guitar day, which was quickly expanded by community feedback into international Appalachian dulcimer day. Is that a fair summation?

Here on FOTMD, Ireland and the US were represented this year.  If there were other countries, please, someone point me to music I may have missed.  On fb, the US, England, Ireland, and Australia were represented yet there may have been others-- I hope so!   There were folks who shared still photographs of instruments to celebrate, too. 

I shared other photos of Dusty's sticker from a couple different dulcimer cases on fb.  Dusty, your sticker may not be as famous as you are yet it is working to catch you!  joyjoy

I'm not a graphic artist, but maybe we could come up with logo for the day. I was thinking of something like a globe with an Appalachian dulcimer across it or perhaps a mercator map of the world with a dulcimer across it. Anyone want to submit some logos for consideration?

Dusty is correct in his explanation. The first event was year one. I have the sticker. I could use a few more to share with dulcimer friends to promote the day, so I'll be sending you a PM Dusty. I didn't get involved as much as I would have liked at the beginning as I was recovering from open heart surgery at the time.

@nate, the discussion did indeed start on the Positive Thread, but my memory is that once we decided on a date and a name, I started this discussion here.

This year was year 4.  But remember that year 1 was not at the end of the year (like a birthday) but at the beginning. So one year in was year 2, etc.  Next year will be year 5.

Earlier in this thread I shared the image of a sticker I had made.  I just got some more, so if anyone wants a couple, send me a PM.  I also made the banner that Robin used to advertise the day here at FOTMD back when we had those banner ads. I'd be happy to offer those images for a DPN article if we want to go that route.

Here is the sticker:IADD for stickers.jpg

And here is the banner:

Hey folks I'd love some clarity about the exact nature of the origins. It seems to me that the discussion in the positive thread started when @dusty brought it up 4 years ago, and this thread was started 3 years ago, but others are saying the holiday is 5 years old. Did this all start with Dusty's suggestion of having a National Dulcimer Day in the positive thread?

Hard to believe we are turning five…if we are going to do a DPN article of the IADD history, we need to do it sooner than later. Our DPN editor has recently accepted my recent article for the November issue.  It would be nice if we can be a feature for the first issue of 2026.  If all of you who were involved in the initial conversations that brought about this grassroots celebration of the Dulcimer would write up a paragraph to share your take on how this all began, I will create an article with those paragraphs and send it on to Fiona. I will go ahead and contact her in the mean time to try and secure a place for the first issue of next year.

It's good to chronicle this stuff for the historical record.  Thanks, @robin-thompson.  So next year will be the 5th year! Maybe we can plan something special for then.

At the heart of this day are the sentiments Robin shared a few posts back: "it's a grassroots celebration of the spread of the Appalachian dulcimer from the Appalachians to countries around the world.  And no one is in charge.  Any creative endeavor featuring mountain dulcimer is welcome for sharing."

After reading some of the recent posts here, I went back and read the posts in The Positive Thread. Steve, I think you should go ahead and write up something about the beginning of International Appalachian Dulcimer Day. Am I correct in thinking that this was our fourth celebration or was it the third. Perhaps for our fifth anniversary we could put Steve's article about the origin of the day in that year's DPN; probably for the issue that usually comes out in February. Or we could all get a cupcake, put 5 candles on it, play Happy Birthday on our dulcimers, and blow the candles out.

International Appalachian Dulcimer Day


General mountain dulcimer or music discussions

Well, everybody, it appears our efforts to create International Appalachian Dulcimer Day has been a success, if we define success as the growing awareness of others of this special day to honor a special instrument.  People who know nothing about our efforts here are now referring to this day and it is becoming part of dulcimer lore.

The question before us now is whether we want the origin of IADD to remain "an unofficial holiday of obscure origin," much like the instrument itself, or whether we want to assert the role of FOTMD in creating the day.

One of us (I would volunteer) could easily write up a few sentences on the creation of IADD here at FOTMD and insert those lines into the Wikipedia entry on the mountain dulcimer.  The evidence (first in the Positive Thread and then here) is clear.

Should we assert our role as the originators or is it best to leave things "obscure"?

Amplification of an acoustic dulcimer


Playing and jamming difficulties...HELP ME!

For what its worth, I have used one of those under bridge pickups that i took off an electric acoustic guitar and put it on a dulcimer, and did not trim the excess of the braided wire, but instead just drilled a small hole at the edge of the fretboard under the bridge for the excess wire to be tucked into. It sounds great and in the future i might be glad i kept the bit of extra length

Amplification of an acoustic dulcimer


Playing and jamming difficulties...HELP ME!

Ukulele fret boards are essentially the same width as those on dulcimers- about 1 1/2 inches. Guitar pickups are wider, but they say they can be cut. That's why I pointed to the ukulele version. 

The piezo element itself looks sort of like a black match stick with a wire on one end. As I recall, I think I just cut the height of the "bone" (probably plastic) saddle down, slide the pickup into the slot, and put the saddle back on top. Some ukulele people appear to put it along the outer edge of the bone saddle, probably raising the strings be a tiny amount.

The rest of the procedure is covered reasonably well in a number of YouTube videos. I think this one is pretty good.

If you are doing it for the first time, you might want to do it on a cheap instrument.

I laughed out loud when I read this post from Buttermilk Junction, some of it is AI I think. At least it is being noticed. Though all of us are “of obscure origin.” The first paragraph is what tickled me, the rest is Wikipedia I think.

☞Buttermilk Junction wishes all of our Facebook fans a Happy National Appalachian Dulcimer Day!

☞Today, Saturday, March 29, 2025 is National Appalachian Dulcimer Day, a.k.a. International Mountain Dulcimer Day, an unofficial holiday of obscure origin that is celebrated annually on the last Saturday of the month of March in honor of the traditional stringed musical instrument that is variously known as the Appalachian Dulcimer, the Mountain Dulcimer, & the Lap Dulcimer. It is noteworthy that, despite the similarity in name, the Appalachian Dulcimer is unrelated to the ancient stringed instrument known as the “Hammered Dulcimer.”

☞According to Wikipedia: The Appalachian dulcimer (many variant names; see below) is a fretted string instrument of the zither family, typically with three or four strings, originally played in the Appalachian region of the United States. The body extends the length of the fingerboard, & its fretting is generally diatonic.

☞Although the Appalachian dulcimer first appeared in the early 19th Century amongst Scotch-Irish immigrant communities in the Appalachian Mountains, the instrument has no known precedent in Ireland, Scotland or Northern England. Because of this, & a dearth of written records, the history of the Appalachian dulcimer has been, until fairly recently, largely speculative. Since 1980, more extensive research has traced the instrument’s development through several distinct periods, & its likely origins in several similar European instruments: the Swedish Hummel, the Norwegian Langeleik, the German Scheitholt, & the French Épinette des Vosges. Folk historian Lucy M. Long said of the instrument’s history:

Because few historical records of the dulcimer exist, the origins of the instrument were open to speculation until recently when Ralph Lee Smith & L. Alan Smith reconstructed the instrument’s history by analyzing older dulcimers. The organological development of the dulcimer divides into three periods: transitional (1700 to mid-1800s), pre-revival or traditional (mid-1800s to 1940), & revival or contemporary (after 1940).

☞In the mid-20th Century, the dulcimer was brought out from relative obscurity by noted American Folk Music singer, songwriter, & Appalachian dulcimer player Jean Ritchie (1922-2015), “The Mother of Folk Music,” who was born at the village of Viper in Perry County in the Commonwealth of Kentucky. Jean Ritchie’s dulcimer playing led directly to the “Dulcimer Revival” of the 1950s & 1960s.

☞According to Wikipedia: The Appalachian dulcimer achieved a renaissance in the 1950s urban folk music revival in the United States through the work of Jean Ritchie, a Kentucky musician who introduced the instrument to New York City audiences.  In the early 1960s, Ritchie & her partner George Pickow began distributing dulcimers made by her Kentucky relative Jethro Amburgey, then the woodworking instructor at the Hindman Settlement School. They eventually began producing their own instruments in New York City. By 1965 the instrument was a familiar presence in Folk-Music circles.

☞The undated photograph depicts Jean Ritchie, “The Mother of Folk Music,” with her Appalachian dulcimer.

Playing and jamming difficulties...HELP ME!

The problem with a stick-on pickup is that it will not only amplify the strings, but also anything that touches your dulcimer like your hands, picks hitting the fret board, and the sound waves hitting it from nearby instruments. While the example shared by Wally is attractive, it will take some skill to cut holes in the side of your dulcimer. Not knowing the width of your fret board you need to be careful about the length of the pickup. One thing that would discourage me from using it is where the wire comes off of the pickup. It seems to me if it fits the fret board the wire would be exposed. L.R. Baggs makes a nice bridge pickup for mountain dulcimers in two widths, but it is over 12 times the price of Wally's example. Plus you would have the expense of an end pin jack. Of course, with any pickup, you will an amplifier and cable. This is all food for thought.

Playing and jamming difficulties...HELP ME!

Since you have a serious need for a pickup, I would not suggest a stick-on mounted on the face of the dulcimer. Particularly since you say you feel sounds from other instruments on it.

I would suggest a piezo pickup under the "bridge" of the sort shown here.

https://www.ebay.com/itm/154154723887?_skw=ukulele+underbridge+pickup&itmmeta=01JR0P8CXC59HVTZEX0R9G8PKC&hash=item23e4566a2f:g:zdYAAOSwiO9fkRip&itmprp=enc%3AAQAKAAABAFkggFvd1GGDu0w3yXCmi1f1a%2FKcJRUkgjxwQyqQw7pljhCoSpJkPekGjrv%2FHmQyoDfqDnxjm6SrWceacTwHEpxive6LhrBaCArs25TycThyGZw2SwBCOiSvptCm5%2Fqzop1Fsc%2FQiJa4vvGCcKXGJPDVPubYXyW6kOSyQwGuZ3Yc3CZRgqJImQu%2F%2B6SWoTgeXfbx0g2Uo33cGOepI4b5%2B9dx0tzeZAB1uEmGVfOOhjkaI1%2F%2BVJO7Y60fW7j1TotNy7taAUvEFBrHgSRsWpZNray4sM%2Fk9HoLN2Gz0D1ObyGt3wf8uRJdkfhoChJR0GG82SBarYMYfHYCdb8cCuCEjWg%3D%7Ctkp%3ABk9SR_7OoZbAZQ

If installed with the pre-amp/tuner you add many of the features found on electric guitars, etc. I installed a similar unit on a cheap, used dulcimer, and it works. I don't use the pickup since I play quietly in an all acoustic group, but I have tested it with a 10 watt guitar amp and it works well. I do use the tuner - it doesn't get lost in my case.

To put it simply and summarize my previous post, it seems that the sound in the middle of the string is "warmer" and "mellow" because it is energetically dominated by low odd overtones that mimic the perfect major chord (#1 = root, #3 = fifth to the octave and #5 = major third to the superoctave). This perfection is gradually broken going towards the bridge, activating less consonant overtones of higher frequencies....

Thank you for this very interesting discussion.

Excited by the question,I took some measurements on the melody string of one of my dulcimers with an acoustic spectrometer. I successively plucked the string at different points along the VSL, starting in the middle (fret 7) and gradually moving toward the bridge.

The measurements showed that all the notes emitted had exactly the same scale of overtones (I measured up to the 27th...).Qualitatively speaking, none of the resulting sounds was purer than any other, wherever the string was plucked.

The only visible difference between all these sounds was the energy associated with each individual wave. I read somewhere in this thread that the octave (second overtone) might be responsible for the mellowness of the note obtained in the middle of the string, but this overtone was actually almost nonexistent at this plucking point, where odd overtones #3, #5, and #7 dominated the vibrational energy. The octave only appeared when moving toward the bridge, around frets 11-12, and disappeared again toward the bridge.

Near the bridge, too, the vibrational energy was distributed between overtones #3 to #8 with higher frequencies, in keeping with the brightness of the resulting sound, and its slightly acidic character, given that the higher overtones become a bit dissonant (this is quite noticeable for #7).

If that helps...

Since we seem to agree where a string is plucked does make a difference, let’s not forget that the main thing is to use the varying sounds to make better music. 

Adjectives for sounds such as “warm”, “bright”, and so on are subjective.  How we perceive and describe things varies.  Discrepancies among us should be met with tolerance. 

There may be a reason why plucking somewhat away from the center might be preferable to plucking exactly in the center.  The mathematical analysis predicts that as the pluck point is moved away from the center, the overtones get stronger, but not uniformly.  The overtone that comes in strongest first is the octave overtone.  To my ear, octaves reinforce (for lack of a better word) a pitch.  Try playing D (open bass string) and then Ddd (open bass string, 3rd fret middle string, open melody string) to get a sense of this.

Thanks for the discussion.

Playing and jamming difficulties...HELP ME!

I play semi-regularly with a small/informal (work) jam band. Not only is my dulcimer impossible to hear over amplified instruments, but I feel their music resonating in my dulcimer more than my own strings.

I've seen those stick-on piezo pickups, but my question is would those even function in an environment where I'm feeling other instrument's in my own soundbox over my own strumming? And if not, what should I look for/ask a luthier to do for me?

I think overtones are associated with our perception of depth. An example of an instrument with almost no overtones is a tuning fork, and an example of an instrument with many pronounced overtones is a cello. 


I also think what Dusty mentioned about the string being floppier near the middle may be the main reason that the tone is so different near the middle of the string. I have noticed that the actual pitch of the string wobbles a lot more when I pluck near the middle. Though very unscientific, I just plucked my string as hard as I could right at the bridge and noted that the frequency wobbled in a range of 1 cent. I plucked as hard as I could at the middle of the string and found that it wobbled in a range of about 4 cents. Since the actual string is producing a larger range of frequencies when plucked at the middle, this might be another factor for why the tone is "warmer" near the midpoint of the string.

I've been wondering a lot about this stuff for a while. I think today is the day I make string striking pendulum and start experimenting!

To my ears, a note does sound more 'clear' when plucked closer to a bridge, but it also sounds more hard and 'tinny' (to me), while a note plucked closer to middle of string sounds rounder and warmer, but I'm not necessarily hearing 'overtones' in it, just a little more depth. The 'tinny' quality strikes me as more of an overtone, if anything. With any description within the human senses, I think there is a certain amount of subjectivity based on personal perception of sound, taste, touch, etc.

Thanks so much, John for that explanation.  Basically, you are defining purity of tone as a minimum of overtones.  That seems logical.

But it also raises a question which I asked earlier, which is how the mathematical definition of purity of tone corresponds to what we subjectively hear.  It certainly seems to our ears that the brighter sound of notes plucked closer to the bridge is more accurate or pure than the warmer sound of notes plucked closer to the center.

My question about fingers and pick was, well, kind of stupid honestly, since clearly those are variables you would want to hold constant if you did a physical experiment and something you would not choose to address in a theoretical simulation.

But there are real-world issues that muddy the cleanliness of your mathematical model.  In your first diagram of the inverted V, h represents the extent of the pluck, or how much the string is pulled before being plucked.  But there is a lot less tension on the string in the middle than there is on the ends.  To pull that string to the same extent by the bridge would result in a much more violent release, increasing the volume, certainly, but also, I assume, changing the nature of the string's vibrations.  I think you might need to add another factor--string tension--to this study and adjust h in that diagram to keep tension constant. Does that make sense?
