At the end, Lucier's field of acoustic phenomena included a dreamy arpeggiated chord, created from the amplifier, the performer and the partial tones in the room.
They were the first to tune the bells with precision, especially with regard to a bell's inner tuning (i.e., of the partial tones that make up a bell's complex sound), and thus to put fully into practice the results of research completed 200 years earlier.
Different music instruments have different compositions of partial tones, e.g., in the sound of a clarinet, mostly odd partials occur.
Until the end of the 19th century, tuning of their partials (component tones in the overtone series) was not seriously undertaken and so lacked uniformity.
Until the 20th century its bells generally lacked an inner tuning, or fixed mathematical relationship of partials (component tones of a bell's complex sound) to permit use of harmony; it also lacks dynamic variation.
Furthermore, Smt-MF mapping filters out too many of the partials from tones in octave 5, making it difficult to perform meaningful comparisons.
As a result, the partials of tones at the lower end of the musical scale are more likely to be compressed than those higher up on the musical scale.
One possible reason for this could be that it preserved the low frequency components, transposing them into a higher perceptual range, whereas Smt-MF tends to cut off frequencies below 440 Hz (A4) and therefore had poorer representation of the partials of tones, particularly in the lower octaves.
If you're partial to earth tones, look for belts, shoes and handbags.
Cataplexy, a symptom characterized by sudden and brief (5 30 s) losses of muscle tone (partial or total) triggered by emotions such as laughter and surprise, is considered pathognomonic of narcolepsy with cataplexy (American Academy of Sleep Medicine, 2005; Vetrugno et al., 2010).
