Piano keys are familiar and easy enough to draw if you're not trying to be exact, but if you want label the dimensions with their exact measurements (like in a CAD drawing), it turns into a math puzzle. The problem comes from the groups of two and three black keys.

This article explains it like this:

If you've ever looked closely at a piano keyboard you may have
noticed that the widths of the white keys are not all the same
at the back ends (where they pass between the black keys). Of
course, if you think about it for a minute, it's clear they
couldn't possibly all be the same width, assuming the black keys
are all identical (with non-zero width) and the white keys all
have equal widths at the front ends, because the only simultaneous
solution of 3W=3w+2b and 4W=4w+3b is with b=0.

To unpack that a bit: in that equation, 'W' is the width of each white key at the front (which should all be the same), 'w' is the width of a white key at the back, and 'b' is the width of a black key.) The first equation is for the group of two black keys (separating C, D, and E) and the second equation is for the three black keys separating F through B.

Since it's mathematically impossible, a constraint needs to be relaxed. The article describes ways to make the white keys have slightly different widths at the back.

If we set c=e=(W-5B/8) and a=b=d=f=g=(W-3B/4) we have a maximum
discrepancy of only B/8, and quite a few actual pianos use this
pattern as well. However, the absolute optimum arrangement is to
set c=d=e=(W-2B/3) and f=g=a=b=(W-3B/4), which gives a maximum
discrepancy of just B/12. This pattern is used on many keyboards,
e.g. the Roland PC-100.

When actually building a musical instrument (instead of just drawing the keyboard), there is a further constraint, described in this article:

The black keys on a piano keyboard, instead of always being centered on the dividing line between the two white keys they lie between, are spaced so that the twelve keys which make up an octave are spaced equally as they enter the internal mechanism of the instrument.

But this means that the "key caps" for the white keys should be slightly off-center compared to whatever rod or lever they're attached to. The author speculates about how to divide this up using various units.

(They seem quite annoying to 3D print.)

I learned to play piano when I was pretty young and my parents wanted me to learn an instrument. Real acoustic piano, music theory, private tutor, recitals, the works. I stopped playing after high school and my lessons ended though, mainly since it felt like it was just another chore and I wasn't enjoying it or playing pieces of my own volition. It's been over a decade since then and most of my free time has been in video games instead. The piano's still there but it's been just another piece of furniture for the most part. I've never seriously considered dusting it off and trying it again, and I'm pretty sure I've forgotten everything I've learned at this point.

Recently though, I got the chance to play Taiko no Tatsujin in an arcade for the first time while in Japan and I enjoyed it a lot despite being a total amateur, and I wanted to go back and play more to get better. That's when a thought crossed my mind - if I could gamify piano playing too, wouldn't that be a good way to trick myself into learning and enjoying piano again?

So I did some digging into what gamified piano software was around now, and Piano Marvel seemed to be the one most suited for being both beginner friendly and also for sight reading. The software itself offers a fair bit of beginner content for free, with the more advanced stuff behind a subscription. You can also connect it to a digital piano to track key presses and score your performance, which is the important gamification part that sets it apart from me just pulling up some YouTube tutorials and trying to follow them.

So I did some digging into digital pianos to see what would work for me learning and budget wise. From what I could glean off of various subreddit and other forum posts, if the end goal is to learn piano and not keyboard, an 88-key with weighted keys is the only thing that comes close, which bumps the cost up to a minimum of about 400 USD for the cheapest decent one, a Yamaha P45. If I didn't have a piano that cost would be fine, but I do and it most definitely sounds better, I just can't connect it to software or plug headphones into it so I don't bother my family if I'm playing at night, and I kind of want both of those. I'm also slightly concerned that my parents might be a bit upset if I do get a keyboard since, again, there's a perfectly good acoustic piano right there that they definitely paid more than 400 bucks for, though I imagine they'd be happy to just see me take an interest in learning piano again.

The most important part of this is that I actually commit to it and play regularly, since it'll all be for nought if I lose interest or turn it into a chore again and stop playing after a few weeks or months. I don't know if a gamified piano software will actually do that for me or if I just don't actually like playing piano after all, but I would like some thoughts. Is there other good software for relearning piano in a fun way? Any keyboard recommendations, preferably not too expensive? Am I being a coward and should I just use my acoustic piano instead?

My whole life I have lived with the regret of not becoming proficient in a musical instrument. I grew up with a piano and acoustic guitar in my childhood home, and I actually took lessons for both but never committed to practicing or improving. As a result I grew up tinkering with both hit never learned how to read music or actually develop any fundamental techniques to play either.

I am an autodidact and have always felt that with the right resources, and a little discipline, I could at least learn enough to play a few songs on either instrument, and possibly with time become a sight reader.

To that end, I am curious, musicians of ~Tildes, what resources are the best to self-learn piano and guitar? Books, videos, apps, anything that you’ve used or know people have used and actually went from complete novice to reasonably proficient?

Thanks and happy new year!

I already play piano and guitar to some degree but never got to learn what I really wanted to play which was blues music.

I see ads here and there about “learn to play following this app!” and was wondering if people had any experiences or recommendations for app-based learning?

My aunt is moving to a smaller apartment and her piano does not fit there, so I offered to take it. Not because I intended to play, but she wanted to keep it in the family out of nostalgia and emotional attachment.

It is under renovation and should arrive perfectly tuned.

But now that I have it, I ask myself: why not play it? I had piano lessons as a kid, and I like classical music.

Is there a straightforward way to learn piano by myself that doesn’t feel like much of a chore? Otherwise, the piano will just linger in my living room.

I just love good piano, whether alone, with vocals, or with other instruments. Two of my all-time favorite artists are Vienna Teng and Regina Spektor, both of whom use it to great effect in their music. Anyone have any good recommendations? I'm open to any genre.

Edit: Awesome suggestions, everyone! I've got quite the playlist right now that I plan to explore over the coming week. Thanks all!

Hi everyone,

Each and every hobby has a start. I'm going to learn how to play the piano. For this, I'm planning to buy an electric piano. There's a regular grand piano I have access to, but they come without headphone jacks, and until I get better I want to limit the scope of audible torture to my own ears as much as possible. So, I could do with some of your advice.

This list of requirements is not meant to limit you in your advice, but serves more as a guideline, to give you an idea of what I'm looking for.

Hard requirements:

• Headphone jack
• The sound library must contain at least a 'normal' piano sound and an electric piano sound (the more it sounds like a dirty Rhodes, the better!)
• At least 128 voice-polyphony
• At least 76 keys, but preferably 88

Soft requirements:

• Weighted keys
• Simulated hammer action
• High repetition
• Ebony and ivory key feel (don't like the sensation of smooth plastic)
• MIDI support so I can hook it up to a computer to try out other sound libraries

Completely unnecessary but cool:

• USB port
• Bluetooth compatibility

If you've learned to play the piano, especially as an adult, any advice you may have for me would be more than welcome, too.

Thank you!
