What Makes It Sound Like Christmas?

Every year, music theory enthusiasts begin to ask the same question: “what makes it sound like Christmas?”

As you can see, this discussion recurs every year in /r/musictheory.

Vox.com has incurred the wrath of Twitter’s musicologists after posting a video focusing on Mariah Carey’s “All I Want for Christmas Is You” that suggested that iiø7 chords are what make it sound Christmassy. The video begins by stating the research question, “What makes Mariah Carey’s song sound so incredibly Christmassy? Aside from the sleigh bells, of course.” They then proceed to discuss the harmonic content of the song and how the harmonies signify Christmassy-ness.

Vox’s declaration that iiø7 chords sound Christmassy irritated musicologists for many reasons, perhaps best summarized thusly:

In the Vox video and in all those reddit posts, and indeed in much of beginner music theory, there is an obsession with finding explanations in the harmonies, specifically, of a song. This is a reflection of the overall bias in music theory: we focus on teaching harmony most of the time. Curiosity about how harmony elicits emotions is natural in this context. It only becomes problematic when this discussion really leads to the exclusion of other music-analytical domains that are more relevant to the track’s signification—namely, timbre!

Lerdahl’s Timbral Hierarchies

The real reason, I would argue, why timbre has been regarded as a secondary musical dimension is that, unlike pitch and rhythm, it has lacked any substantial hierarchical organization.

–Fred Lerdahl, 1987

Yesterday I read “Timbral Hierarchies” by Fred Lerdahl, originally published in 1987 in Contemporary Music Review Vol. 2. This article is post-GTTM (A Generative Theory of Tonal Music) and represents an attempt to explain how timbre prolongations, or at the very least timbral hierarchies, might be possible, in much the same vein as L&J-type metrical or tonal hierarchies.

This article is another curious entry in the outpouring of timbre music theory research that occurred in the mid-1980s (see also Cogan 1984, Slawson 1985). Since I wasn’t researching in the 1980s, I’ve wondered myself what the music theory community was like at this time, and what in the culture propelled this sudden interest in timbre. I presumed that this was due to a wider access to 1) spectrograms, a useful visualization tool for timbre, and 2) digital synthesizers, which allow for the level of precise control necessary in many perception studies. Lerdahl identifies out another possible impetus for a sudden rush to theorize timbre: “The issue has sharpened with the recent rise of computer music. There is now such an infinity of timbral possibilities that the need for some kind of selection and organization has become acute” (136).

I’ve found it funny in the past that I study 1980s popular music, and that so many of the existing articles and books on timbre research also date from the 1980s. But this quote in particular helped me realize that the unifying factor in all of this is rapid technological advancement.

Beat of a Different Drummer?

In my dissertation research I’m turning toward drum machines. It’s a natural extension of my ’80s sound inquiries: if the Yamaha DX7 was so important to the ’80s sound, drum machines like the LinnDrum and the Roland TR-808 were at least equally important.

Analyzing the timbre of drum machines using my existing apparatus has revealed how biased toward pitched phenomena theories of timbre really are. For example, so many theories of timbre are completely preoccupied with overtones/partials and their relative loudness. (For more info on spectrogram analysis, check out the first half of this blog post.)

This spectrogram is of a harmonica synth playing a melody. Time is on the x-axis in seconds. Pitch is on the y-axis in Hertz (higher Hz = higher pitch). The bottom line of this spectrogram, at around 500 Hz, is the fundamental pitch. Colloquially we just call this “the pitch.” The parallel lines running above the fundamental are the partials of this sound. You don’t hear them as separate notes, but instead you hear a change in timbre.

But for many percussion instruments, drums and cymbals and such, you won’t see any partials like that at all. Even drums that are pitched don’t really have partials running in multiple parallel lines above it.

These are samples from a Roland TR-808: bass drum, low tom, mid tom, high tom, snare, closed hi-hat, open hi-hat, clave, and handclaps. Notice how these are all just thick bars of sound, not at all like the parallel strands in the above example.

So it does us no good at all to talk about partials, how those partials compare to the ideal natural harmonic series, whether there’s vibrato, etc. Yet, that’s the majority of the focus of spectrogram analyses.

Over the next few weeks I’m going to start finessing how we can talk about timbre in non-pitched percussion instruments. For now, back to the grind…

’80s-inspired music

Last Wednesday I was a featured contributor to the podcast Pop Unmuted on an episode about ’80s music—listen here.

We are currently living in a kind of ’80s revival. Google “How do I make my song sound 80s?” and you can see hundreds of posts on online forums from amateur producers looking for an ’80s sound.

The funny thing about this is that of course the ’80s was an entire decade of music, and there were tons of different genres and styles that were going on at this time. Obviously it would be difficult to name even a single characteristic that was represented in every ’80s style. And yet there’s something that persists in the collective memory of people today that can be called an ’80s sound.

How do we make something sound ’80s?

Reading about embodiment (Heidemann on timbre)

Since I first saw it, I’ve been fascinated by this video of an impressionist singing in the style of many different singers. I love karaoke, and I love doing impressions of quirkier singers myself (Celine Dion, Idina Menzel, and Britney being a few of my favorites)—I’m nowhere near as good as Christina Bianco, but it’s good to have goals.


Actually, watching Christina Bianco convinced me that it must be possible for anyone to sing beautifully. It must all just be muscles and vowel placement and so on, if this one woman can make all these different kinds of voices!

Never having studied the voice seriously, it’s hard for me to describe how I would make these different voices. But it’s probably the first thing you’d try to do in describing this video to someone else. I’m reading Kate Heidemann’s article, “A System for Describing Vocal Timbre in Popular Song,” recently published in Music Theory Online 22/1, which I find a completely wonderful way to discuss vocal timbre. This article pinpoints the kinds of distinctions I’m tuning into when I watch that Youtube video above.

A theory of attacks?

Studies have shown that the attack (onset) of a sound plays an important role in a listener’s ability to accurately determine the sound’s source. In Saldanha and Corso 1964, listeners were able to identify the source of a tone with 50% greater accuracy if the attack of the sound was included in the sample, as opposed to a sample that cuts out the attack and plays only the sustain of the sound.

Therefore the attack of a sound must greatly influence our perception of timbre. In order to summarize the most important aspects of a timbre, my methodology must have an adequate way of accounting for the attack of the sound. How to do this? At the moment, my methodology is based on a system of oppositions. My first thought, of course, was an opposition between sounds with a fast attack and a slow attack. But isn’t this oversimplifying? There are probably degrees of variance between “fast” and “slow.” (Now you have a little insight into what I think about when I walk between my apartment and the cafe.)

The critique of binaries as being over-generalizing is leveled at me a lot. But McAdams 1999 shows that perhaps this isn’t actually a damaging oversimplification.

How Things Sound

“Any accurate analysis of rock music must therefore ultimately account for its timbre and studio production at least as much as on the traditionally analyzed parameters of tonality, harmony, and meter; in other words, how the song sounds is as important—if not more so—than what is sounding.”


Kevin Holm-Hudson, “The Future Is Now … and Then: Sonic Historiography in Post-1960s Rock”

Trying out a new post format today—posting a quote from a recent reading and reflecting on it a teensy weensy bit.

Holm-Hudson’s idea of sonic historiography, tracing the history of rock music through the sound of that music, is integral to my approach and my (still under construction) thesis statement for my dissertation. Part of what I want to do is define the “’80s sound” through its technology, analyze the timbres of those technologies, and finally raise issues of aesthetics and reception and how they relate to those timbres/technologies.
