Expectation and surprise: a primer from the Mountain Goats and the Flaming Lips

T he way we hear music is defined entirely by what we expect to hear.  These expectations can come from anywhere, including before music even begins – if it’s a late Romantic opera, my ears are primed for something a lot more harmonically complex than a mid-80s pop song.  That’s a no-brainer; Richard Wagner’s disparate tonalities would be way more surprising in a Journey tune than they are in Tristan und Isolde.

More simply, though, our ears create expectations based on what they’re already hearing.  So, when a song starts in one key, you can reasonably expect it to continue in that key.  When you hear a certain four-chord progression a few times, you expect that progression to continue.  When your brain hears a downbeat every four notes, it expects the song to stay in 4/4.

But when one of those expectations goes bust – say an F-sharp appears in the key of C major, or the chord progression abruptly changes – well, we notice it.  That’s the reason it sounds weird to hear that F-sharp, or for a measure to suddenly add a beat.  There’s some research out there that posits that this expectative setup and subsequent surprise could be a reason why some music seems more interesting than others.  In other words, our brains are pros at being efficient; they pay less attention to things they expected to happen, so that when something unexpected occurs, it sticks out much more.  And because of that, we actually pay more attention to challenging music than we do extremely simple songs.1

I n other words, the setup-and-surprise shtick is rewarding to hear.  And it appears often in pop music, much to my enjoyment, and hopefully yours too.  Let’s start with the chorus of the Mountain Goats’ “No Children” – but be sure to listen to the first 1:10 or so, so that you’re properly primed when the good stuff hits.

A chord/lyric transcription:

01 (Dbm)   (Gb)        
02 (Dbm)   (Gb)
03 (Gb)    (Ab)        
04 (Db)
05 (Db) I hope that our few re- (Ab) maining friends
06 (Gb) give up on trying to (Db) save us.  I
07 (Db) hope we come out with a (Ab) failsafe plot to piss
08 (Gb) off the dumb few that for- (Db) gave us
09 (Db) I hope the fences we (Ab) mended
10 (Gb) fall down beneath their own (Ab) weight... and I
11 (Db) hope we hang on past the (Bbm) last (Ab) exit.  I
12 (Gb) hope it's already too (Ab) late... and
13 (Db) I hope the junkyard a few blocks from here
14 (Bbm) someday burns down... and
15 (Gb) I hope the rising black smoke carries me far a-
16 (Gb) way, and I never come (Ab) back to this town a-
17 (Gb) gain. In my
18 (Ab) life, I hope I
19 (Db) lie, and
20 (Bbm) tell everyone you were a good wife, and I hope you die,
21 (Db) I hope we
22 (Ab) both die.
23 (Db)
24 (Dbm)   (Gb), etc., return to verse..

Hopefully you had a moment of surprise at the end of that chorus.  It’s really a clever bit of songwriting on John Darnielle’s part.  The lyric, obviously, is a bit shocking.  “I hope I lie and tell everyone you were a good wife” is frank enough, but “I hope you die, I hope we both die” is, well, a very strongly-worded statement.  That alone would probably grab a listener’s attention.

But a major part of what makes that line work so well is the unexpected way the chorus is phrased – that is, the way its melody and harmony are structured.  Up until this point in the song, everything has been in groups of two.  Each line in the verse is two measures long, demarcated by the initializing “I hope”s.  And even the chorus opens up like this – the G-flat measure is paired with an A-flat measure, followed by D-flat/B-flat minor, and D-flat/A-flat.  Each line of the chorus comes in a pair: “In my life / I hope I lie,” “and tell everyone you were a good wife / and I hope you die.”

Until, that is, the stunning “I hope we both die,” which Darnielle declines to pair with a second line.  Instead, it simmers – and that simmering takes place over a single measure, not a pair.  Both antecedents (the lyric, the final chorus measure) come without a satisfactory conclusion, and so the line lingers in your mind for an awkward moment before the song returns to its opening chords.2  And of course, I probably don’t have to draw you the connection between the unsatisfactory conclusions of the music and what we can probably assume was an analogous experience in Darnielle’s life.  [Edit.: John Darnielle tweeted this to me a few hours after I posted this: “No analogous life events tho – all fiction in that song!”]

O n a happier (and less uncomfortably candid) note: “It’s Summertime” by the Flaming Lips.  I don’t want to spoil anything, so without further comment, listen to just the opening just-under-five seconds:

This intro is a great example of how good our brains are at building expectations.  It’s only four seconds, but that’s enough to establish a meter in the mind of the listener.  We hear a group of sixteen notes, the first of which is clearly accented, and then a second group of notes, apparently identical, begins.  There are some fancy terms (namely, “metric projection”) for how our mind hears this.  In effect, the idea is that when our brain hears 1) a unit of time, followed by 2) the beginning of a second unit, it expects the second interval to equal the first, and for repeating identical intervals to continue indefinitely.3  On top of that, sixteen is a very easy number of beats for our Western ears to understand; it’s four groups of four – so usual, in fact, that they even call it the “common time.”  So when the second group begins, there’s little doubt in our minds what the meter is, and more importantly, where the downbeat is (at the beginning of the song, and then there’s another one sixteen sixteenth notes later, of course).

But Wayne Coyne ain’t gonna let us off so easy.  Play on!  The first ten seconds or so is plenty:

Wait, what?  Pause and listen again, if you need to.  Here’s what happened (pretend the Os are the notes):

         band should join here -->|X
band actually joins here ->|X (???)
in retrospect, it was actually this:
  (band joins on downbeat) |X        

WTF, Wayne.  After taking just enough seconds for the bass guitar to create the expectation of a certain meter, the rest of the band crashes the party a beat and a half early.  It’s disorienting!  And the bass even sticks with the misaligned downbeats until the lyrics come in.  It rights itself temporarily at about 0:46, but the misalignment – a form of metrical dissonance called “displacement dissonance” – comes back for good at 2:05.4

This song actually asks a philosophical question about expectation and music that I love to think about.  Which is more important: what you’re experiencing at a specific moment, or what you know about that moment afterward?  Tell me what you think.  I have my own thoughts, of course, but I’ll expound on them later.

1 On the other hand, there’s the fact that your brain gives itself a dopaminergic pat on the back every time its predictions come true, which is why it can be rewarding to hear a song you already know.  In reality, there’s probably a sweet spot between total randomness and bland repetition.  NPR’s blog 13.7 speculated a bit back in February about this “Goldilocks zone,” though it doesn’t delve in very far.

2 The word “antecedent” carries some extra implications when it comes to music theory, but those can largely be ignored in this instance. I’m referring simply to the fact that this is a unit that inherently carries the expectation of a second, complementary unit.

4 The term “displacement dissonance” comes from an unusual monograph on meter by Harald Krebs called Fantasy Pieces: Metrical Dissonance in the Music of Robert Schumann. Instead of the usual dry music theory fodder, Krebs imagines a lively conversation between Schumann and a friend at a coffee shop where in between cups of joe and mid-afternoon desserts, the two posit a slew of interesting ideas about meter and rhythm.
