Chiptune musings
----------------
Something happened today that has finally triggered me writing this phlog post,
which has been half-formed in my head for quite a while. As most of you
probably know, I have a weekly chiptune show on aNONradio, SDF's streaming radio
station with volunteer DJs. Not only do I have a show, somehow I actually have
listeners, too! One of them is recently-returned-to-gopher Kvothe, who last
month wrote[1]:

I definitely think there are sub-genres of chiptune, and I have fairly distinct
tastes with regard to them. This post will be a rambling, over-thought dump of
thoughts on the matter which may, just possible, be of interest to fellow fans.
In a lot of ways, professing to "like chiptunes" does not make a lot of sense.
The only sensible definition of chiptune as a genre is something like "music
made with sound chips", where the context makes it implicit that "sound chips"
means something old or primitive sound chips; if you permitted modern DSP
chips with high bit depths and sampling rates to be included, the term would
become meaningless, because those chips can sound like anything at all. So,
this makes "chiptune" a genre defined entirely by instrument, and saying you
"like chiptunes" is frankly as weird as saying you "like guitar music" or
"like piano music". Those are versatile instruments which can play all *kinds*
of different music, which don't necesssarily sound much alike, and it would be
quite strange to enjoy them all. It makes a lot more sense to say that you
like Jazz piano or classical piano or whatever.
This raises the question of whether there is any *stylistic* content to the
concept of chiptunes, and there most definitely is and it ties in very closely
with the question of "authenticity", which is (or perhaps was) a major point
of debate for hardcore chiptune nerds.
Genuine vintage sound chips are increasingly rare, as are functioning hardware
platforms containing them and the skill set to compose music on them directly.
A lot of modern chiptune music is actually produced on typical desktop
computers using software synthesisers which try to emulate old soundchips,
either using high quality recordings of original hardware or just reproducing
the same synthesis technology of the original in software. This kind of music
is sometimes called "fakechip" by purists, but the extent to which it is
"fake" depends a lot on what imbues "real" chiptunes with their "real" status.
If chiptunes are defined entirely by the characteristic sonic texture of the
instruments, then it's hard to argue that software emulations somehow lose
this texture. Plenty of people will claim they can hear the difference
between the original and a software emulation, but in the vast majority of
cases they are kidding themselves. Afterall, we are very often talking about
*squarewaves* here. One squarewave of a given frequency sounds like any
other. And, yeah, the analogue output stage of the original output platform
might have some characteristic high or low frequency roll off, but that's not
hard to recreate in software either, at all.
Despite having this view, I do consider a lot of music as "fakebit" and I
confess I do kind of turn my nose up at it sometimes. It's not because the
sonic texture is noticably different, because it very often isn't it. It's
a style thing.
Early chiptunes (i.e. those made before "chiptunes" as a self-aware genre
label existed) have some characteristics which originated from the
constraints of both the sound chips themselves, and the computers driving
them, and the context that they were often a part of a game. If you are
genuinely interested in this, you owe it to yourself to check out Linus
Akesson's "Elements of chipmusic"[2], but I will try to give a brief sense
of it here. For example, "real music" tends to make extensive use of chords,
i.e. playing not individual notes, but groups of 3 or 4 notes with a specific
relation to one another simultaneously. Depending on how the notes are
related, the overall chord can take on an emotive quality that plain notes
by themselves lack. Possibly you are familiar with the basic examples of
major chords sounding "happy" and minor chords sounding "sad". Most of the
sound chips used in making chiptunes only have 3 or maybe 4 separate
oscillators on them, which makes chords problematic. If you play a
three-note chord, you have totally committed all of your musical resources.
You can't use chords in a melody played over a bassline with drums for
rhythm, you can only play the melody by itself. Chiptune artists over
come this by simulating chords with arepggios or "arps". Instead of playing
three notes simultaneously, you quickly and rapidly loop through playing
those three notes for a much shorter period of time than you would play
your chord. This imparts *kind* of the same effect. Major arps sound happy,
and minor arps sound sad, but they only occupy a single channel. This is
why so many chiptunes have that rapid, gargly sounding effect.
There is plenty of other stuff like this happening, and so technical
constraints, as well as the fact that "real" chiptunes were often the
soundtrack to a game (and hence had to sound exciting or adventurous or
scary), as well as the fact that they were composed in the 80s or 90s and
hence were influenced by the 80s or 90s "real music" the composers were
listening to, all combine to create a characteristic chiptune sound which
goes beyond just the timbre of the instruments.
Software synthesis on modern computers makes it possible to completely
disregard this characteristic style. You can have as many channels as you
like without running out of oscillators, the tracks can run for as long as
you like without running out of memory, you don't have to structure your
song so it loops nicely in a game, and instead of being inspired by the
electronic music of the 80s and early 90s, you can try to immitate modern
day stuff like dubstep. Emulation doesn't change the fundamental sound
(although many people combine authentic-sounding chiptune instruments with
very non-chiptuney "fat analogue bass" in the same piece), but it does
completely open up the compositional horizons and results in a much wider
range of music, which makes it perfectly reasonable to like some of it and
not like like other parts.
Personally, I tend to like "fakechip" stuff which I don't feel is too
much of a departure from the genre's origins, although there are
exceptions, I'm sure. Stuff which makes no attempt whatsoever to
connect itself to that heritage and is just making electronic music with
bleeps and bloops less often appeals to me, just like a lot of electronic
music made without bleeps and bloops doesn't appeal to me either.
Kvothe mentioned that a lot of chiptunes he has heard are too "preppy",
and I agree. I suspect, although I absolutely can't back this up with
anything resembling hard data, that a lot of this comes from younger
artists who did not really grow up with the computers, games and music,
but have gotten into chiptunes as part of the widespread interest in
retro/vintage just-about-anything, and who are trying too hard to infuse
their music with what they think of as an "old school video gamey" vibe,
which results in an exaggerated, cheesy, fast-and-cheerful sound that I
don't like. But take that with a pinch of salt, it could absolutely
just be me being a grumpy old gatekeeping bastard.
Something else vaguely related to the notion of authenticity in chiptunes
is the trend (which until recently I thought had subsided, to which I
will return) of small chiptune elements being used in mainstream pop
music. This usually just took the form of very brief, very obviously
video gamey samples, or brief little bits of melody, and was obviously
just cashing in on the retro/vintage craze, but it became surprisingly
common. I will admit I never really liked this, even before the incident
where Timbaland plagiarised a melody from a Finnish demoscene artist's
C64 song[3], which probably turned a lot of fans against the practice.
I fully admit that this is stupid and it wrong, but it felt like "theft"
of an important component of geek culture. I know that "cultural
appropriation" is "a thing" these days, but in general I am pretty deeply
sceptical of that idea, which seems to me almost like an explicitly
racist re-invention of the worst aspects of modern Western intellectual
property law. I *don't* believe that hardcore computer geeks who have
been listening to chiptunes for decades have an exclusive right to the
artform, and I believe it's silly of me to feel some kind of nerd rage
when popstars play "our" music. But I still have to admit, I felt it.
I was reminded of my thoughts on this matter last week when, while
listening to the radio, I heard a song which was *alarmingly* chiptuney
for mainstream intended-for-the-public radio of the kind you might play
in a cafe. Even at the height of the trend for pop artists to include
chiptune elements in their songs, it was only ever a nod in that
direction, with the overall song being 90:10 or 80:20 generic pop music
to chiptune. This song I heard the other day seemed pretty close to
50:50 to me, which is really surprising. I wish I knew what it was.
