This week dear friend, Terri Murphy, sent me a link to an old Radiolab podcast on Musical Language. I am a Radiolab virgin and I have been anticipating listening to a broadcast soon, so now seems a good time.
The program was chock full of interesting stuff and, of course, I LOVED the sound based format, which went very far in illuminating THIS topic. One section focused on the work of music psychologist Diana Duestch who studies the relationship between tonal languages and musical abilitites. She demonstrated an interesting phenomenon with tonality, music and language. She took a recording of her own voice talking about her work and isolated a phrase where she put a distinct tone with each syllable. When this phrase was looped, it became a song fragment. The show really emphasized the song fragment by having musicians and singers add harmonies and improvisations over and around the fragment. Then she played the recording of her talking where this phrase was used and the brain hears her burst into song at the moment of the phrase. I laughed out loud when I heard it. I am always looking for “sound jokes” and this was one. It is the shock and joy (there’s a concept) of re-cognition. She has CDs of sound illusions, which I am going to check out.
In another segment, a neuroscientist has recorded the sound of the electrical firings in the brain when we hear sound. When we hear harmonious, consonant, rhythmic sounds these firings are very steady and even. When we hear sounds that are dissonant and arrhythmic, the firings are more erratic. Now current scientific thought is that consonance and dissonance are fixed positions in the ear. Radiolab asks the question, “What if the auditory cortex is more malleable than science thinks?” Then the hosts used the premiere of Stravinsky’s “The Rite of Spring” as an example of the possibility that people’s auditory cortex can be shaped by exposure to new musical relationships. At the Paris premiere in 1897, the audience rioted and left the theatre. A year later, the Paris audience sat enraptured. This example is fraught with cause/effect issues (a provocative ballet choreographed by Najinsky and artistic rivalries all factored into the premiere, but were not a part of the performance a year later), but the idea that the pounding, dissonant chords that drive “The Rite of Spring” contributed to the flare up is not too much of a leap for me. Especially when they talked about the neurons whose job it is to “render things pleasant” in the auditory cortex. One of the hosts even goes so far as to throw out the possibility that music/sound artists are in a tug of war with the brain. Given what we are learning about neuroplasticity, this may be the case.
There have been times when I have worked on a piece of music and cringed for a moment at some chord or passing tone that did not sound quite right to my ear. Most of the time I bring it in line with the tonal center, but, occasionally, I leave it and listen to it 5 or 6 times as I am working. If it passes this test, then I put some time between listenings. If on the next listening, it is still working in a quirky way for me, I will leave it. At these moments I feel like my auditory cortex is being redirected and reshaped to allow in some new and strange relationship. It feels expansive and I usually go for the expansiveness.
