When most of us hear a song for the first time, we aren鈥檛 necessarily listening to chord progressions, identifying the counter-melody or finding a correlation between key changes and the sound of the words used.
But with a few keystrokes, hundreds of lines of code and help from the phonetics library, CU-Boulder music theory instructor Kris Shaffer, a colleague in Oregon and two students will use computers to do just that.
It鈥檚 a melding of the romantic era and the digital era鈥攎usic theory research at its best.听鈥淲e鈥檒l start with a 20-song set by Schubert,听顿颈别听蝉肠丑枚ne M眉濒濒别谤颈苍,鈥澨齋haffer explains.听鈥淔rom there, we鈥檒l compare the phonetic data鈥攃hanges in the kinds of sounds the poet is using鈥攖o the key changes and the chord changes and see if there鈥檚 a pattern.鈥
In other words, the research will show whether Schubert made his musical choices based on the words by poet Wilhelm M眉ller, who wrote听顿颈别听蝉肠丑枚ne M眉濒濒别谤颈苍.
So, where does the computer fit in?
Digital Humanities
For Shaffer, a traditional music theorist, the idea of the digital humanities didn鈥檛 become an interest until grad school.听鈥淚t鈥檚 been popular for a while among literary scholars. But in music, there鈥檚 still only a small set of people using computational analysis,鈥澨齢e explains.听
Shaffer embarks on this corpus-based study, dubbed听, with the help of another researcher he met several years ago, University of Oregon music theorist Stephen Rodgers.
鈥淪tephen is a theorist and a singer, so he thinks about how his mouth and his vocal chords are moving as he鈥檚 singing, but he also thinks about the musical structure and how it鈥檚 changing at the same time,鈥澨齋haffer says.
A shared interest and a hunch that there might be a reason for the musical changes in听顿颈别听蝉肠丑枚ne M眉濒濒别谤颈苍听led the two together.听鈥淪chubert is very artful in how he engages with the text, so we expect to see patterns,鈥澨齭ays Shaffer.听鈥淲e decided to collaborate, encode the songs based on harmonic and melodic structure and look at the phonetics of the poems line by line.鈥
The two students involved in the summer-long project鈥攐boist Jordan Pyle and music education major David Lonowski鈥攍anded the gig in part thanks to an Undergraduate Research Opportunities Program (UROP) grant.
For Pyle, the project represents an exciting and fascinating crossroads of music, phonetics and poetry. 鈥淭his interdisciplinary, multilayered work is what I look for鈥攂oth academically and professionally,鈥 she explains. 鈥淚 strongly believe that the most rewarding and interesting discoveries happen at the intersections of disciplines.鈥
She says this is also a chance to improve as a musician. 鈥淚t allows me to engage with the works in different ways that serve to enrich and nuance my performance interpretations.鈥
Agile Research
The process for inputting and analyzing the songs sounds more like software engineering than musical research. Shaffer says it starts with the poems the songs are based on.
鈥淲e encode each word using the International Phonetic Alphabet. Then we categorize the phonetics, and I build a program that creates tables from that data that we then analyze,鈥澨齭ays Shaffer.
The table will show the probability of certain notes or chord progressions coinciding with certain phonetic sounds.听鈥淭hen we can start to look for patterns and determine whether our hunch is just a coincidence,鈥澨齋haffer explains.
And it just may be.听鈥淲e鈥檙e conditioned to pay attention to certain things when we listen to music. We听might be so familiar with these songs that we think we鈥檙e hearing things. But computers aren鈥檛,鈥澨齋haffer adds.听鈥淪o the computer can either confirm our suspicion or prompt us to change course. If we see a pattern emerge in this first set, Jordan may turn this into a more in-depth research project.鈥
Even if the end result of the research is that this is all just a coincidence, Shaffer says there are still questions to be answered.听鈥淭hen we can start to ask why. Why was the song written this way this time? What was the composer trying to convey?鈥
Pyle hopes this process is only the beginning of her involvement.听鈥淢y main goals are to learn to conduct my own research using these methods and turn the project into an honors thesis,鈥 she says. 鈥淚 also want to present at the annual Special Undergraduate Enrichment Programs (SUEP) research conference, perhaps attend other conferences and work with Kris to get some works published on this topic.鈥
A New Understanding of Music
The project is just kicking off. To begin, Lonowski and Rodgers, who have a deep understanding of the phonetic alphabet, will encode the poems; Pyle will encode the music; and Shaffer will build the computer program. But because the insights come from the interaction of these different areas, the four will converse regularly and trade roles for different parts of the project.
Depending on how things go, the process of analyzing just the first 20 songs could take all summer. But even so, Shaffer stresses, there are still people who undertake these kinds of projects by hand.
鈥淚t鈥檚 manageable with a handful of songs. But if we were to do with pencil and paper what the computer is doing, it would take months,鈥澨齢e says.
Just as in music creation and recording, Shaffer says technology could be a game changer in the study of music theory. 鈥淭he digital humanities offer a great opportunity to combine what computers do best鈥攃runch numbers and perform basic tasks reliably and quickly鈥攚ith what humanists do best鈥攖hink creatively, critically, even skeptically, about what we perceive.
鈥淲hen we combine those two perspectives, we can learn even more about art, language and culture than if we follow either one of them on its own.鈥
The team will be blogging and tweeting about the process throughout the summer. Follow along at听听and by following Kris Shaffer鈥檚 twitter handle,听.
