The 17-Tone Puzzle — and the Neo-Medieval Key That Unlocks It
The 17-tone Puzzle — And the Neo-medieval Key That Unlocks It by George Secor A Grave Misunderstanding The 17 division of the octave has to be one of the most misunderstood alternative tuning systems available to the microtonal experimenter. In comparison with divisions such as 19, 22, and 31, it has two major advantages: not only are its fifths better in tune, but it is also more manageable, considering its very reasonable number of tones per octave. A third advantage becomes apparent immediately upon hearing diatonic melodies played in it, one note at a time: 17 is wonderful for melody, outshining both the twelve-tone equal temperament (12-ET) and the Pythagorean tuning in this respect. The most serious problem becomes apparent when we discover that diatonic harmony in this system sounds highly dissonant, considerably more so than is the case with either 12-ET or the Pythagorean tuning, on which we were hoping to improve. Without any further thought, most experimenters thus consign the 17-tone system to the discard pile, confident in the knowledge that there are, after all, much better alternatives available. My own thinking about 17 started in exactly this way. In 1976, having been a microtonal experimenter for thirteen years, I went on record, dismissing 17-ET in only a couple of sentences: The 17-tone equal temperament is of questionable harmonic utility. If you try it, I doubt you’ll stay with it for long.1 Since that time I have become aware of some things which have caused me to change my opinion completely. -

White Paper: Acoustics Primer for Music Spaces
WHITE PAPER: ACOUSTICS PRIMER FOR MUSIC SPACES ACOUSTICS PRIMER Music is learned by listening. To be effective, rehearsal rooms, practice rooms and performance areas must provide an environment designed to support musical sound. It’s no surprise then that the most common questions we hear and the most frustrating problems we see have to do with acoustics. That’s why we’ve put this Acoustics Primer together. In simple terms we explain the fundamental acoustical concepts that affect music areas. Our hope is that music educators, musicians, school administrators and even architects and planners can use this information to better understand what they are, and are not, hearing in their music spaces. And, by better understanding the many variables that impact acoustical environ- ments, we believe we can help you with accurate diagnosis and ultimately, better solutions. For our purposes here, it is not our intention to provide an exhaustive, technical resource on the physics of sound and acoustical construction methods — that has already been done and many of the best works are listed in our bibliography and recommended readings on page 10. Rather, we want to help you establish a base-line knowledge of acoustical concepts that affect music education and performance spaces. This publication contains information reviewed by Professor M. David Egan. Egan is a consultant in acoustics and Professor Emeritus at the College of Architecture, Clemson University. He has been principal consultant of Egan Acoustics in Anderson, South Carolina for more than 35 years. A graduate of Lafayette College (B.S.) and MIT (M.S.), Professor Eagan also has taught at Tulane University, Georgia Institute of Technology, University of North Carolina at Charlotte, and Washington University. -

Pedal in Liszt's Piano Music!
! Abstract! The purpose of this study is to discuss the problems that occur when some of Franz Liszt’s original pedal markings are realized on the modern piano. Both the construction and sound of the piano have developed since Liszt’s time. Some of Liszt’s curious long pedal indications produce an interesting sound effect on instruments built in his time. When these pedal markings are realized on modern pianos the sound is not as clear as on a Liszt-time piano and in some cases it is difficult to recognize all the tones in a passage that includes these pedal markings. The precondition of this study is the respectful following of the pedal indications as scored by the composer. Therefore, the study tries to find means of interpretation (excluding the more frequent change of the pedal), which would help to achieve a clearer sound with the !effects of the long pedal on a modern piano.! This study considers the factors that create the difference between the sound quality of Liszt-time and modern instruments. Single tones in different registers have been recorded on both pianos for that purpose. The sound signals from the two pianos have been presented in graphic form and an attempt has been made to pinpoint the dissimilarities. In addition, some examples of the long pedal desired by Liszt have been recorded and the sound signals of these examples have been analyzed. The study also deals with certain aspects of the impact of texture and register on the clarity of sound in the case of the long pedal. -
On an Experimentum Crucis for Optics
Research Report: On an Experimentum Crucis for Optics Ionel DINU, M.Sc. Teacher of Physics E-mail: [email protected] (Dated: November 17, 2010) Abstract Formulated almost 150 years ago, Thomas Young’s hypothesis that light might be a transverse wave has never been seriously questioned, much less subjected to experiment. In this article I report on an attempt to prove experimentally that Young’s hypothesis is untenable. Although it has certain limitations, the experiment seems to show that sound in air, a longitudinal wave, can be “polarized” by reflection just like light, and this can be used as evidence against Young’s hypothesis. Further refinements of the experimental setup may yield clearer results, making this report useful to those interested in the important issue of whether light is a transverse or a longitudinal wave. Introduction In the course of development of science, there has always been a close connection between sound and light [1]. Acoustics stimulated research and discovery in optics and vice-versa. Reflection and refraction being the first common points observed between the two, the analogy between optical and acoustical phenomena has been proven also in the case of interference, diffraction, Doppler effect, and even in their mode of production: sounds are produced by the vibration of macroscopic objects, while light is produced by vibrating molecules and atoms. The wave nature of sound implies that light is also a wave and, if matter must be present for sound to be propagated, then aether must exist in order to account for the propagation of light through spaces void of all the matter known to chemistry. -
Linear and Nonlinear Waves
Scholarpedia, 4(7):4308 www.scholarpedia.org Linear and nonlinear waves Graham W. Griffithsy and William E. Schiesser z City University,UK; Lehigh University, USA. Received April 20, 2009; accepted July 9, 2009 Historical Preamble The study of waves can be traced back to antiquity where philosophers, such as Pythagoras (c.560-480 BC), studied the relation of pitch and length of string in musical instruments. However, it was not until the work of Giovani Benedetti (1530-90), Isaac Beeckman (1588-1637) and Galileo (1564-1642) that the relationship between pitch and frequency was discovered. This started the science of acoustics, a term coined by Joseph Sauveur (1653-1716) who showed that strings can vibrate simultaneously at a fundamental frequency and at integral multiples that he called harmonics. Isaac Newton (1642-1727) was the first to calculate the speed of sound in his Principia. However, he assumed isothermal conditions so his value was too low compared with measured values. This discrepancy was resolved by Laplace (1749-1827) when he included adiabatic heating and cooling effects. The first analytical solution for a vibrating string was given by Brook Taylor (1685-1731). After this, advances were made by Daniel Bernoulli (1700-82), Leonard Euler (1707-83) and Jean d'Alembert (1717-83) who found the first solution to the linear wave equation, see section (3.2). Whilst others had shown that a wave can be represented as a sum of simple harmonic oscillations, it was Joseph Fourier (1768-1830) who conjectured that arbitrary functions can be represented by the superposition of an infinite sum of sines and cosines - now known as the Fourier series. -

In this introductory paper, we make the linkage between the use of big data and Econophysics, a research field which uses a large amount of data and deals with complex systems. Different approaches such as power laws and complex networks are discussed, as possible frameworks to analyze complex phenomena that could be studied using Econophysics and resorting to big data. Keywords: big data; complexity; networks; stock markets; power laws 1. Introduction Big data has become a very popular expression in recent years, related to the advance of technology which allows, on the one hand, the recovery of a great amount of data, and on the other hand, the analysis of that data, benefiting from the increasing computational capacity of devices. -
The Physical Modelling of Society: a Historical Perspective
Physica A 314 (2002) 1–14 www.elsevier.com/locate/physa The physical modelling ofsociety: a historical perspective Philip Ball Nature, 4-6 Crinan St, London N1 9XW, UK Abstract By seeking to uncover the rules ofcollective human activities, today’s statistical physicists are aiming to return to their roots. Statistics originated in the study ofsocial numbers in the 17th century, and the discovery ofstatistical invariants in data on births and deaths, crimes and marriages led some scientists and philosophers to conclude that society was governed by immutable “natural” laws beyond the reach ofgovernments, ofwhich the Gaussian “error curve” became regarded as the leitmotif. While statistics .ourished as a mathematical tool of all the sciences in the 19th century, it provoked passionate responses from philosophers, novelists and social commentators. Social statistics also guided Maxwell and Boltzmann towards the utilization ofprobability distributions in the development ofthe kinetic theory ofgases, the foundationof statistical mechanics. c 2002 Elsevier Science B.V.
