Good news:
--Primary computer
has been repaired and heading home.
--I made it home
alive
Bad news:
--My current
internet connection is sporadic at best which is making it more or
less impossible to keep up with anything online.
--Even though the
flea situation seems to be under control and heading toward
completely fixed the cat is still afraid to come inside.
--Worse still, while
it's usually fine to have someone stop by to make sure she can get in
to eat and make sure the food bowl isn't empty, her fear of the fleas
changed this in a way that I didn't expect: Even with someone making
regularly checking on her, she hasn't been eating enough because she
won't stay in the house long enough to do so. Now that I'm back I
can work to address this BUT she's already lost a lot of weight in a
short time and that's not good.
--Coming back home
means coming back to a place where I have no hot water. And the cold
water is fracking cold. No more showers and washing dishes is
difficult at best.
--I really miss
not-overheating due to the availability of air conditioning.
--All it took was
for me to be back home for one day and I ended up missing my
medication and my pages. Go me.
Random news:
I have a tendency to
think up musical instruments. I assume the reason that no one has
built them, or that I haven't heard of them if someone has, is that
either no one wants them or not enough people want them for them to
exist/be common enough for me to hear about.
At the moment I'm
thinking about guitars. Guitars for people who lack the capacity to
play guitars. Keyed guitars.
Do such things
exist? No idea, I'll look into it when I have a better internet
connection.
But the reasoning is
basically this:
Frets on a guitar
are a sacrifice made to deal with the fact that people can't place
their fingers perfectly and most people don't really want to try.
Maybe that's going
too fast.
Strings vibrate, the
vibrating strings transfer vibrations through the bridge to the
soundboard, the vibrating soundboard moves a lot more air than the
strings could on their own, the moving air comes out of the
resonating chamber through the sound hole, and that's what makes a
guitar sound the way it does.
Short version:
Strings vibrate thus sound.
The note produced
depends upon the vibration of the string which in turn depends upon a
variety of factors.
Someone looking at a
steel string guitar (not to be confused with steel guitar, which is
something else entirely) will quickly note that the strings are not
all the same size and indeed aren't even all made out of the same
materials. That's because the idea is to have the strings be about
the same length but tuned to different pitches.
Tension also matters
which is why guitars have those fun tuney knob things.
You can't change the
composition of the strings while playing and most people don't screw
with the tension.
Changes in pitch are
done by changing the length of the string. Put your finger down on
the fingerboard (also known as the fretboard) and that functions as a
new end for the string. Sort of. It would if there were no frets.
On a fretless guitar
(they do exist) where your finger pushes the string into the
fingerboard functions as one end of the string. The bridge is the
other end. The distance between the two is the functional length of
the string.
This new length with
vibrate differently than the old length (which was from the nut to
the bridge) and as a result a different note will sound when the
string is struck, picked, strummed, or hammered.
The problem with
this set up is that you're probably not going to press the string to
the fingerboard in just the right place to produce a note on
the chromatic scale.
(The chromatic scale
being: A, A sharp/B flat, B, C, C sharp/D flat, D, D sharp/E flat, E,
F, F sharp/G flat, G, G sharp/A flat)
Thus frets. Frets
are designed so that pressing the string on the fingerboard will
result not in an uninterrupted length of string from the bridge to
where you're pressing but instead the fret will get in the way
creating an uninterrupted length of string from the bridge to the
fret (and then a much shorter length from the fret to where you're
pressing which doesn't really matter.)
This changes string
length from continuous to discrete. Instead of infinite possible
lengths each string can only take on a handful. Specifically the
number of frets plus one. So, say, 25. 25 possible lengths is much
easier to deal with than infinite.
The frets are not
placed at random. They're positioned so that the resulting string
lengths will be about the notes of the chomatic scale. It's not
exact (and there are various methods that have been used to try to
make it closer to right, though) but if you depress a string on the
fingerboard of a well tuned fretted guitar you can be reasonably sure that
the note produced when that string vibrates will be pretty close to
one of the notes on the chromatic scale.
There is a trade
off. That's why fretless guitars still exist. Some people would
prefer to go without the trade off at least some of the time.
A standard fretted
guitar cannot play quarter tones. Well, it can but you'd have to
tune it specifically for that purpose and all strings so-tuned would
be unable to play the normal semi-tones. A fretted guitar cannot
make a smooth slide without a special tool intended for the job.
Slides are definitely possible, but the frets make it so they're …
I guess “bumpy” would be the best word.
The whole point here
is that the guitar, like most musical instruments, is entirely about
finding a trade off between ease and versatility that is desirable
for the player.
-
That trade off being
so visible in the design (don't know for sure but I'm guessing most
people think of guitars as having frets) invites one to think of
other possible trade offs.
Fingerpicking is
awesome, but it requires being able to get your fingers in the right
places at the right time to pick the desired string without
accidentally sounding or muting another string and it requires either
the maintenance of finger nails with which to pick or the use of
fingerpicks designed for the job but which may interfere with
something else you want to do. (The standard fingerpick holds onto
the finger by going around it, which is going to be a problem if you
want to use that finger for anything where having a usually-metal
band around it would interfere.)
Assuming that
someone doesn't have a disability that prevents them from
fingerpicking, the standard solution to the difficulty of
fingerpicking is practice. That is, after all, how one gets good at
any style of using a musical instrument.
A different solution
would be a mechanically picked guitar. Instead of relying on fingers
to pick some mechanism or other (there are many possibilities) would
do the picking and it would be controlled by keys. One could rest
the fingers on the keys to keep them in the right place, since the
picking is done by the mechanism not the fingers there would never be
a worry about picking one string accidentally affecting another
string. So forth.
It's not like
mechanical picking isn't a thing. The harpsichord is a mechanically
picked instrument that's the size of a piano.
I wouldn't imagine
anything like piano keys on a keyed guitar, probably something more
the size and shape of the keys on an old fashioned round-key
typewriter. (Which suggests going for a steampunk aesthetic even
though I lean toward a much more all-wood old-fashioned aesthetic
when thinking about this.)
Six keys and you've
got the picking of individual strings down. You could add six more
to silence individual strings. Add what I'm suddenly going to call a
space bar to strum all the strings, and a second one to silence them
all and you've suddenly transformed the actions of the picking hand
into something more like typing than guitar playing. Different skill
set, space for different focus.
Nothing terribly
complex about any of this (though it would involve some annoyingly
small parts) and I assume the reason that it hasn't been done is that
no one really wants it.
But that's what I've
been thinking about as I sit here without reliable internet.
On the other end of
a guitar is, of course, a neck. Where the frets live.
The body of the
guitar invites this kind of thinking because of two things:
1 There's a limited
number of things you can do there.
2 There's a lot of
space to work with.
The neck sort of
shuns similar thoughts because of two things:
1 There's a much
larger number of things you can do there.
2 There's hardly any
space to work with.
To put that into
more words, near the bridge all you can do to the strings is sound
them or silence them. There are multiple ways you can do that, but
this whole thing is about trading versatility for ease of use. Six
strings, two functions --> twelve keys assuming we don't double
up functions with keys. (Which one totally could.)
I mentioned adding
in keys to strum or silence all the strings, so now we're up to 14
keys.
14 keys that can be
put basically anywhere. One of the nice things about mechanical
linkages is that there's no reason that they have to begin anywhere
near where they end. (That's also a nice thing about electronics.
When my internet adapter is working there's no need for the computer
to be near the modem.)
The body of a guitar
has a lot of space so there are a lot of options for where to put
those keys.
At the other end
things are very different.
At the simplest,
with all advanced technique ignored, there are as many things to do
to a guitar string on a neck as there are frets. I used the 24 fret
guitar as an example before. 24 things you can do to a string times
six strings is 144. Gross.
One could go about
looking at the neck the same way we looked at the body (KEYS FOR ALL
THE THINGS) but that would lead to 144 keys to put on the neck which
does not have a lot of real estate.
I'm not saying it
couldn't work, it totally could work. And I find myself imagining
the keys being like laptop keys and covering the whole neck so you
don't even see that it's a stringed instrument and it gives off this
whole “Age of Computers” vibe.
So, sure, it totally
could be done. There's just not that much point in doing it.
The neck is
different from the body. It's completely flipped with the options
versus area thing and, more importantly, it serves a completely
different purpose. It deserves a different treatment.
Notes usually aren't
chosen in random ways. They are connected to one another. Guitar
music makes strong use of chords.
There are way too
many chords to possibly do them all, but what I can see is the
potential to work out the most common cords a musician is going to be
playing and making those available at the push of a button. Or, to keep terminology consistent, the use of a key.
Things become much
easier for people who have difficulty contorting their fingers into
the necessary shapes to make the cords.
And at this point I
would like to add that all of this talk about a guitar that will
presumably never be built isn't just about people too lazy to
practice. Actually it's not about them at all. It's about finding
something to think about when I'm sitting all alone in a house where
most of the things don't work and then taking that something to think
about to its clear conclusion given the trajectory it started with.
But that is neither
here nor there.
If we imagine a
guitar that is easier to play by the use of modifying the means to
play it in order to make manual dexterity less of an issue (though
it's still an issue because keys have to be hit, it's just often
easier to deal with them than with strings) the people who would benefit include more than just be people who lacked the manual dexterity because of a
lack of practice. It would also benefit people who lacked it because
of age, illness, or injury.
This is, more or less, what I do when cut off from the internet and without human contact.
Think about random stuff.
That sounds like a possible thing. The autoharp is a strummed instrument with buttons for standard chords, for example, although it works by having strings for all the notes and muting the unneeded ones rather than by pressing frets.
ReplyDeleteLooking at the Wikipedia page for guitar chords, I imagine that it might be mechanically convenient to have a regular tuning - e.g. the all-fourths tuning - and do chords in two steps: first choosing a root, then which type of chord. The regular tuning makes changing the root a matter of just moving down one fret (mostly).
...that said, I don't know enough about guitar or disabilities to know what would be the best way to make the former and the latter not get in each other's way.
One of the "hallmarks" of 80s music was a syntheizer keyboard that was rigged in a similar way to a guitar, so that it could be played with many of the same flairs, so someone, I think, has at least thought a little about this. I would guess, with enough musical theory knowledge, it would be possible to design an instrument where one hand controlled the root note and the other, the modifiers to that note or chord such that it would be easier on the hands, and it could be housed in a container that looked guitarish, so that no person would be the wiser.
