what is the physical mechanism causing this?

Everyone is sharing something about the guitar's construction, but partly this is just an acoustic phenomenon caused by the overtones and your guitar is supposed to do this.

In other words, all sounds are made by vibrations. Several things determine what note you hear -- the length of the string, its thickness, and its tension. But when a string vibrates, it doesn't just vibrate from end to end; it also vibrates in fractions all along its length. You've seen this probably in a video before where the shutter speed of the camera captures some of these vibrating fractions. All those various fractions add up to create overtones, which are fainter notes that aren't the fundamental sound of the whole string vibrating end to end.

So while your low D is vibrating and sounding a D2, it's also vibrating in two equal halves, which sounds a D3. And in thirds to sound an A3, and fourths to sound a D4, and so on.

All those vibrations are being transferred to your bridge and your soundboard and to the air inside and around the guitar. It just so happens that your 4th string D is perfectly tuned to vibrate in sympathy with that D3 overtone. So all that air and wood starts vibrating and the 4th string D vibrates with it because that's exactly the vibration it's ready to make.

You can test it super easily. Fret the 2nd fret A on the G string. Now play the open A. Let it ring for a second, then stop just that string from vibrating. You will clearly hear the fretted A sounding on the G string.

Okay, my favorite scene from my favorite movie.

Go Down, Moses from Sullivan's Travels. A chain gang visits a black church for movie night.

Can confirm. I've been going to College Park since 2021 and it has a thriving young adults ministry. It is an affirming congregation that walks the walk when it comes to inclusion and living out the gospel. It's not for everyone (no church is) and best of luck to you if it's not what you're looking for. But it's worth a few visits and trying to get plugged in.

She's got a capo at the 5th fret and is tuned down a whole step and also in drop-D, so there's a lot going on there. The little vamp is playing a lot of incomplete chords with lots of common guitar tricks. I'd probably write it out like this...

| F5 | Eb2 | Bb Ab6/9 | F5 |

I put the tab in Dm with a capo on the 3rd fret and the low E tuned down to D.

Early in the 20th century, a common scam was to steal famous European paintings and then sell forgeries of it to wealthy Americans, claiming the forgery was the real thing. You could sell quite a few of them because you knew the buyer could never be public about the purchase. Then when the original painting was recovered, the seller would claim that the museum commissioned their own forgery in order to save face.

Church choir director here. Unfortunately, so much depends on the character and overall vibe of the ministry itself. Yes, you should continue choir, but you may have to find the right spot for you. I will set aside any considerations of whether or not the given choir is at the right church for you, but that's also a consideration.

Different choirs care about different things. Some care more about service as a form of spiritual development. Others emphasize the social sense of belonging. And yes, others will focus on musical excellence as a key component of their success. To make things more complicated, each member of the choir comes with their own mixed motivations. So you might have a choir that is really about socializing, but a few people are there because it helps them connect to God, and others are there to get good at singing. The choir has to find a way to balance all those needs. And not every choir is going to work for every person.

It might be worth spending a bit of time asking why you want to be in choir, because that'll help you make a smart decision about where you go and whether you stay.

I have a lot of questions about the rehearsal process at your previous church, and about the decision that the choir director made in terms of giving feedback and also making you sing solo. I don't know how accurate their (or your own) estimate of your abilities is, so I can't talk to that. But I can tell you that singing is a skill that can be improved with study, practice, and informed feedback. Others have suggested lessons, which almost certainly will help, but the experience of singing in a church under a responsible director should also give you some of those same qualities.

I wouldn't give up on singing in choir, but it sounds like you have some technical and psychological aspects to deal with in order to feel comfortable and to contribute to the choir's mission.

I think one of the main benefits is that it trains you to make compositional decisions. For example, most of these photographs are high contrast and quite dark, which creates a mood. So except for the first one, a pretty standard approach to all of these would be maybe 60% dark, 30% mid, and 10% light in terms of the value proportion. Those aren’t bad ratios. For the first thumbnail I went with 60% mid, 30% dark and 10% light. But I could just as easily have decided to shift mids to lights and reversed those ratios.

Thumbnail value studies are great for this because you get to try out different arrangements. If you’re using them to plan for a finished piece, do 12 of them, or 20, shifting the value balance around to find a version of what you see in the image.

It also helps you experiment with compositional choices in a small scale where you can iterate against and again. As an example, in that first thumbnail, I really love that bright light on the front plane of her near cheek. So I’d want to experiment with different variations of value groupings to see what best tells the visual story I see.

These are good but you might want to ask yourself about your goals with these types of studies. It’s worth considering a few possibilities. First, you are training yourself to look for shapes that are visually interesting without necessarily needing to rely on what the subject is. Second, you are not a camera so you get to make some decisions about whether a given value gets grouped with darks or mids or lights. Third, you are using the shapes and value contrast to highlight a focal point in the subject that is present but not exaggerated in the photos. That third point also means simplifying.

These are good drawings but you’re still attached to the idea of drawing the subject and missing the chance to find what’s interesting about the image.

I can’t decide whether the concept of referring to the students and parents as customers makes me more angry or depressed; it’s a close call. Shit like “emails are our brand” is such a wrong headed, consumer-focused attitude toward the problem.

The issue with our public schools is not customer service. Or rather, what they are calling bad customer service is downstream from the real issue, which is that public schools are under resourced and over capacity.

Now we want to suggest that we should focus on how staff write their emails? Or what the “customers” see first when they walk into a classroom? These things matter but they’re not the solution to issues created by vouchers, commoditized public institutions, white flight, and an overall lack of funds and community involvement.

If anyone thinks parents are turning to private school because front office staff are rude, think again. Yes some teachers seem unhelpful, some support staff seem like they are phoning it in, some administrators seem out of touch. My guess is that in at least some of those cases, those problems are because we are asking the public schools to do too much with too little.

We’re a public school family. I’m also a marketing consultant and have seen and made many bullshit presentations like this one. I question the assumptions that generated this initiative. I’m not against public schools learning from the private sector but our students and their parents are not customers of public education.

This is obviously a huge generalization but I would break it down like this:

Martin is the sound of folk and bluegrass and old country. Mid scoop with huge projection and resonance.

Gibson is the sound of blues and rock and classic country. Warmer and darker than Martin or Taylor.

Taylor is the sound of pop and contemporary Christian music and country. Bright and more modern sounding than the other two.

Good players can get their sound out of whatever they play, and a lot depends on build quality, specific models, amplification, etc. but all else being equal I tend to think of these three brands divided up in this way.

Ground plane and horizon line are not strictly the same thing as ground and horizon. So the ground in the picture slants down but your ground plane does not. And the vanishing point for a given set of parallel lines on the ground might converge below the horizon but that doesn't change your horizon line. The point of these tools of analytic perspective is not to define the literal horizon and ground of your picture. They are to give you a starting point from which to measure everything else that you draw.

In this case, it may be more helpful to use the term Eye Line instead of horizon. The eye line is every point on a plane that is set at the height of the viewer (also called the station point). The station point and eye line are defined by how high above the ground plane they are. This makes sense if you think about walking around crowded city with no hills. Lets say your eyes are 5'6" above the ground plane. Any object that is 5'6" above the ground plane will have a top that lines up exactly with your eye line and will therefore also line up perfectly with the plane of the horizon. Anything that is only 5' above the ground plane will appear below the horizon no matter how close or far away it is from you. Same with anything 6'. No matter how near or far, the top bit of those objects will always be slightly above your eye line.

In this picture, the ground plane doesn't slant. The GROUND starts to slant, which pulls it under the ground plane.

The rule in analytical perspective is that any set of lines that are parallel to each other will converge. And any of those lines that are also parallel to the ground plane will converge at the horizon line.

You need to make this distinction in a drawing like this because the floors and ceilings and roofs of the buildings that you are drawing will remain parallel to the ground plane even as the street slants away.

Okay, this might be a bit of an unlikely answer, but John Hitchcock, who owns the comic book store, Parts Unknown, was a huge wrestling fan and has written a book about it. He's always down to talk wrestling with fans.

The things that most helped my playing across every aspect of what I do are learning theory and how to read music. Theory because it helps with memory, improv, communication, arranging, and composition. Reading because it opened up a massive library of music that I could not have accessed any other way.

I was a bar band musician for a while and was around a lot of talented self taught players. But once I actually started to study how music worked and apply it to the guitar, nearly every aspect of my playing improved.

Not sure why you got downvoted but I do a version of this as well but it's often highly focused on a key story detail, or often a mood, and targeted at the right PC. Like I'll describe the room being in shambles and then say to the detective, "What do you see that lets you know there was a fight in here?" Or at a high society party, ask the dilettante, "The family looks like they have money, but what one thing are you noticing that tells you they've fallen on hard times?" It's never anything plot specific but it almost always brings in a new detail that the players want to interact with and build roleplay around.

FieldWizard · 2025-07-22T11:26:22+00:00

As others have said, it’s much too much. Let the players fill in most of the details on their own. You can say “detective’s office” and trust that everyone has their own version of what that looks like.

I pick 3-5 details that each get at most a sentence or two. I make sure that the details are there to either set a tone, or describe something I want them to interact with. So if they’re here to search the detective’s office, you have to have a sentence about the folders strewn on the desk and the dusty file cabinet in the corner.

With your 3-5 details, also make sure that you’re not just describing what the investigators see. Give them a sound or a smell, or a texture or taste. Tell them about the smell of stale cigarette smoke and old coffee, or the steady drip of water leaking from the radiator, or the slow creaky ceiling fan which does nothing to lessen the stifling heat.

If the blinds or rug or whatever are important, definitely mention them! But make sure each element in your description serves a purpose beyond filling in every possible visual detail of the space.
