I wanted to add mass but not stiffness, so I took a series of dense metal washers (and one nut) and used poster putty to attach them to the back. One is in the center and the rest in a circle around that, roughly halfway between the rim and center. The are not connected so as to not add stiffness and they are spread around so as to spread the mass evenly. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/c32027b3-81e1-4a42-b0ae-46927a179975/Screenshot+2025-10-15+at+9.51.36%E2%80%AFPM.png iii Mandolin Blog -

Curiosity meets Resonance, part 1 - Spruce wedge hit with a felt mallet, (I wrote this over a few days so "felt mallet" and "felt hammer" are the same thing) This is a wedge of spruce that is roughly 18“ long, 7" wide and 3/4” thick on one side and about 1/4” thick on the other. I'm holding it on the long thick edge about 1/4 the way from an end and tapping it in the middle with a felt covered wood hammer. Each peak on this graph is a resonant frequency in the piece of wood. You can see the highest peak is at 511 Hz, which is near the C above middle C— that’s the main note that can be heard. In person it is hard to tell there are more than one or two frequencies present, but the FFT graph shows that there are several. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/cc191635-b861-41f4-9fbc-6610570f1e4d/Screen+Shot+2024-06-11+at+5.19.42+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Spruce Wedge hit with a steel hammer This is the same spruce wedge, this time tapped with a steel hammer, held and hit in the same place as before. You can see the same frequencies show up, but in different heights and ratios compared to each other. Imagine the sound difference between a soft and a hard hammer hitting the same thing, this is the graph version of that. The main note is the same (511 Hz) but the tone is different (different arrangement of higher frequencies). https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/0736073e-6f16-40a5-ad6a-808dd20975e0/Screen+Shot+2024-06-11+at+5.28.49+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Mahogany billet hit with felt mallet Here is a piece of mahogany, roughly 18" long, 12" wide and 3/4" thick. This piece of wood has many more resonant frequencies than the spruce, even though it is hit by the same hammer and held in a similar way. This is due to the different properties of mahogany vs spruce including its stiffness, density, dimensions and grain. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/172dcca1-9772-48a4-ba04-050fdf9e8a94/Screen+Shot+2024-06-11+at+5.31.56+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Mahogany billet hit with steel hammer The same piece of mahogany shows many more peaks when hit with the steel hammer, particularly above 2500 Hz. What does 2500 Hz sound like? Listen here, it’s quite annoying, like the first tone of a fax machine or dial up modem, or an appliance alert beep. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/8d2d1402-e9f6-4fa2-841d-0ba2e0d06ecc/Screen+Shot+2024-06-11+at+5.37.45+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Steel Bowl hit with felt hammer Looking now at thin gauge metal (it is ~ .012" thick) we get skinnier peaks compared to wood. The spacing on these peaks is wider and there is a regularity to them. The skinniness and smoothness of the metal resonance peaks has to do with its density and stiffness and homogenous composition compared to wood. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/af5e2b98-645f-4f15-831d-5c590b6dd718/Screen+Shot+2024-06-11+at+5.44.33+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Square Steel Tube hit with felt hammer This 1/2" steel tube (.06" thick walls, 5x thicker than the bowl) also has skinny peaks, but the bases of the peaks are also skinny and distinct from each other. I think it's because a steel tube is considerably thicker and stiffer and narrower than the bowl. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/c893027c-3cf3-4b5a-9f78-11490dc9b8e8/Screen+Shot+2024-06-11+at+5.47.45+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Electric guitar, open low e string (82 Hz), unamplified: An electric guitar string does not excite the dense body into vibrating very much, so we see the characteristic tall skinny peak of a metal string. Notice the clear peak of the fundamental at 82 Hz. Note also that the first harmonic (second peak at 165 Hz) is taller (louder) than the first. This louder first harmonic is quite common in vibrating strings. Side-note: next time you are near the low e string on a guitar, see if you notice the first harmonic is louder than the fundamental, it might be! https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/627aef92-d17d-4878-98c8-285d5dacc1ab/Screen+Shot+2024-06-11+at+11.56.02+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Banjo head: light and flexible surface The main resonant peak of a banjo head (polymer head strung up but the strings are muted), has an onion shape with a very wide swooping base and a tapering peak. The other peaks in the graph around 300 Hz+ are not something we will concern ourselves with today. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/ffb622fd-9954-4fb3-8651-09baa73d0725/Screen+Shot+2024-06-11+at+5.49.38+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Strings on a Banjo Here we have a plain open high g string (397 Hz) played on the open-back banjo. You can see the wide base and skinny top of the fundamental frequency, as well as the harmonics with relatively wide bases compared to the following examples. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/291ae77c-9fbf-487a-a1a1-8d8944d0d9de/Screen+Shot+2024-06-11+at+6.03.37+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Wooden Box: Tenor Ukulele This is the wood portion of a tenor ukulele, only tapping the top of the instrument with the felt hammer and muting the strings like I did with the banjo. You can see the main resonance at 187 Hz. You can see there are several modes of vibration happening at the same time in the wooden box. Also note the wide bases and irregular tapering peaks. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/d6874f81-679e-4a35-a73d-eabe5e7b6436/Screen+Shot+2024-06-11+at+5.53.13+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Tenor Ukulele C string (262 Hz), open A tenor ukulele open C string (262 Hz) creates a fundamental with a wide base, as well as a wider base on the first harmonic. Interesting note: There is a shoulder (187 Hz) on the left side of the fundamental peak. This is the 187 Hz resonance in the graph above, the one we saw when tapping the body with the strings muted. We will see this again very soon. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/6c7c8917-32d9-4a43-b604-145bf654998c/Screen+Shot+2024-06-11+at+6.06.55+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Wooden box: mandolin top taps Like with the tenor ukulele, here is the tap of a mandolin when only the top is tapped with the felt hammer and the strings are muted. The two main peaks to keep track of here are 298 Hz and 450 hz. See how wide and tapered they are compared to string peaks. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/6b9bdd56-bee0-4bb7-8062-94e968bd05a1/Screen+Shot+2024-06-11+at+6.13.25+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Mandolin tapped on top AND back Let's tap the back as well as the top on this mandolin. Note the first two peaks are the same (298 and 450 Hz), but now there is a third main peak at 567Hz. This frequency peak wasn’t very prominent in the first graph, and really only showed up when we tapped the back, so it must come from the back. This method of elimination can be used to figure out where most of the important resonances come from. The method will also show which frequencies show up in more than one place. For instance, on this instrument, 298 Hz will show up just about anywhere you excite the instrument--ESPECIALLY if you blow over the soundholes... more on that in a later post! https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/6d4c0f21-6a6f-405d-ac13-5593e207f965/Screen+Shot+2024-06-11+at+6.17.09+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Open G (196 Hz) The open G (196 Hz) on the mandolin has a much more prominent first harmonic (392 Hz) than fundamental. This is typical of the lower range notes of most mandolins. The first harmonic peak (392 Hz) has a wide base that covers the first two tapping resonances (298 Hz and 450 Hz). When hearing the open G, your brain says you are hearing the 196 Hz frequency, but if you listen for it you'll notice the first harmonic is actually louder! This is true of many mandolins and is a byproduct of our physiology. See also that there are 6 more prominent harmonics after the first, nearly all detectable with your ear, but they aren’t obvious to most people, you have to listen for them. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/698e4d83-80da-4cc9-94f7-8c8caa0d397d/Screen+Shot+2024-06-11+at+6.19.26+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Open D (293.6 Hz) The open D frequency (293.6 Hz) is very close to the first highest tapping peak (298 Hz) on this instrument, so it gets a wide base and remains broader to the top when compared with the open g strings. Its harmonics are evenly spaced and pointy (but not all the same height, nor evenly diminishing). And here there are only 3 or 4. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/5c97c648-7246-4e16-972a-2f4493b402d9/Screen+Shot+2024-06-11+at+6.21.10+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Open A (440 hz) The wide base of the open A (440 Hz) leans heavy to the left and you can see a small peak at 294 Hz, the first tapping resonance. The right side of the fundamental peak drops off at a steep angle. The second tapping frequency of 450 Hz shows up as a slight shoulder on the right side. The three harmonics are pointy and relatively weak. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/29608939-4ea9-4bac-9ab4-7db99ad56152/Screen+Shot+2024-06-11+at+6.23.27+PM.png iii Mandolin Blog - Curiosity meets Resonance, part 1 - Open E (659.25 Hz) The open E fundamental peak (659.25 Hz) is a stand-alone, peaky peak. It has three harmonics associated, one barely registering. But noteworthy here is the clump of peaks to the left of the fundamental which are the tapping frequencies of the body of the mandolin, and separate from the base of the fundamental peak. So, playing the e strings also excites these LOWER tapping frequencies. Just as it did on the open A, and just as it does on many more notes. https://images.squarespace-cdn.com/content/v1/60a6c6a87d500f4249caec0b/717cbbe0-7b07-440e-b091-b4aa1c13f5c6/Screen+Shot+2024-06-14+at+12.04.48+AM.png iii Mandolin Blog -
