[[ A short review of the recent NOVA program entitled "What is Music?" ]] Covering as vast and controversial area as the scientific study of music in the space of one hour would daunt even the most intrepid producer. Nonetheless, NOVA succeeded in touching many highlights in this field in an entertaining way which provided insight to the general public and a bit of meat for specialists in this area. This reviewer found the coverage to be a "cook's tour", giving short shrift to much contemporary music and entire fields of perceptual and compositional theiry. However one might quibble with the editor's choices, a three program series might have provided a more balanced presentation. Nonetheless, the breadth achieved was admirable. To many scientists and lay people alike, the scientific study of music is oxymoronic. At the very least, this program dispels that notion. The program starts by ostensibly answering the question of what musical sound is by examining Adrian Houtsma's work (published couple of years ago in the journal "Music Perception" amongst other places) in redesigning carillon bells to shift the normal "minor third" partial to become a major third -- "sweetening" the bells' sounds. Demonstrations of old vs. new sounds, the synthesis and analysis of the bells, the actual construction of the new bells and the psychoacoustic experiments to determine listener preferences all contribute to the bells' story. An exploration of two "synthesizers' follows. The first, a 12th century organ, shows how the same notated music changes when played with different timbres (or colors). A quick cut to Wendy Carlos' studio contrasts the early Moog with its subtractive synthesis of sound with current additive synthesis techniques. Further musical "editing", using her original "Switched-on Bach" recordings, showed the control over sound available to composers. She then constructed a xylophone sound for the narrative, graphically demonstrating additive synthesis. The original analysis of real sounds needed to reconstruct them with a synthesizer was explained by Max Mathews and Jean Claude Risset in a reconstruction of a scene from 10-20 years ago in which they examined trumpet tones in Bell Lab's anechoic chamber. The finding that trumpets' frequency spectrum changes according to intensity and pitch was news! Xavier Rodet at IRCAM then used that information to build a startlingly realistic human voice component by component, similar to the earlier xylophone example. This segment ended with a synthetic soprano blithely singing the Queen of the Night aria from Mozart's Magic Flute. The thread switches next to the construction of musical instruments, using a violin as a prototypical example. An investigation by Texas Chemistry professor Nagyvary to duplicate the physical condition of the famous Stradavarius and Guarnari stringed instruments revealed several startling conclusions. Wet cured wood and semi-precious gemstones in a special varnish appear to be crucial ingredients in the old masters' work. A modern instrument made with Nagyvary's techniques was examined and played by a professional violinist, a protege of Jasha Heifitz, and the fellow who cared for Heifitz' instruments. The new instrument was pronounced as "one of the best modern violins" by both player and hearer. Max Mathew's synthesized "drum" machine sets the stage for pursuing the relationship of live performer with an instrument. This odd contraption made 10 years ago looks like a crude forerunner of today's MIDI drum machines, but provided surprising expressive capabilities, as demonstrated by composer Richard Boulanger. The elusive concept of musical style is exemplified by a brief comparison of "straight" and "stylized" performance of the Messiah Overture by Handel. Caroline Palmer, at Cornell, then explores some of the parameters of "musical" playing style, compared with "unmusical" playing. A demonstration using a snippet of Brahms underscores her points. Christopher Hogwood, famed for his "authentic" performances of early music, also lends insight into how playing styles have changed. The thread of the program switches again to explore "how music affects our minds." An interview of Diana Deutsch of San Diego demonstrates auditory streaming (although that technical term wasn't used in the show). That is, disparate melodies are combined in a subject's head to produce new melodies and musical lines not present in the original sound source. This effect was sonically and graphically illustrated using the contrived stimuli of the psychoacoustic experiments, then dramatically put into practice using a passage from Tchaikovsky's Sixth Symphony. The final major segment follows Australia's Manfred Klynes investigation into emotion in music. He worked on simple gestures which could "universally" be interpreted in various simple emotions (e.g., joy, anger, sorrow) and then translated them into sounds. Subjects who learned the gestures could later easily identify the associated emotion. The sounds were likewise easily paired. Most surprising was the near perfect agreement of Aborigines in Australia with the more conventional subjects -- demonstrating the cross-cultural effects of these apparent "universals." The program ends with a survey of many of the previous participants, asking each the question posed by the show's title. The answers are varied and reflect the personal nature of music to each of us. As mentioned at the beginning of this review, this reviewer felt the producers did a reasonable job presenting a balanced report from different areas given the format limitations. Unfortunately most of the work was from 10-20 years ago and the show did not reflect the current state of the art either in technology, composition, psychological research, or performance. Modern "art" music was given no coverage, for example; the musical example were all traditional 18th and 19th century chestnuts. Musicology, sound recording techniques, compositional aids, "musician's workstations," medical knowledge of music and musicians, neurological effects of music, et alia were all omitted. The selective nature of the program and the age of most of the work will surely frustrate many musicians and specialists. However, interested lay people will gain a bit of insight into a complex endeavor, while preserving that mystery which seems to lie in the heart of the organized sound we call music. -Peter "It's my life" Marvit : Peter Marvit Hewlett-Packard Labs in Palo Alto, CA (415) 857-6646 : : Internet: <marvit@hplabs.hp.com> uucp: {any backbone}!hplabs!marvit :

I thought the psychological material on the Nova was pretty weak. This may reflect the skimpy format rather than the work of Clynes and Palmer.

Does Palmer have a definition of unmusical? Or is she relying on her subjects' concept of unmusicality? If I had to pick someone unlikely to produce an unmusical performance, a career musician like Malcolm Bilson seems a good bet. Isn't it likely that, for him, "unmusicality" is a musical style, rich in all the things he's been taught to avoid? So aren't her conclusions about the nature of musicality just a digest of what modern classical musicians have been taught to do? > The final major segment follows Australia's Manfred Klynes investigation > into emotion in music.

Was his experiment really conducted under the circumstances shown in the program? The subject we saw was given a slip with the seven universals written out, and asked to match to them the gestures he had been taught. If this is what Clynes did, the reality of the universals is pretty dubious. If one of the gestures reminded me strongly of broccoli and faintly of sex, I would only have one choice. Does anyone out there know this work? I trust there's more to it than we saw on Tuesday.
