The Mystery of Pipe Acoustics
The mystery of pipe acoustics FRANTIŠEK KUNDRACIK Comenius University in Bratislava, Faculty of Mathematics, Physics and Informatics, Department of Experimental Physics Introduction Students at school are not given a lot of information about sound formation in pipes. Explanation is reduced to the description of the standing sound wave in the pipe and importance of the sharp edge, which is struck by the airflow. The aim of this article is to answer in more detail three fundamental questions about the sound formation in pipes: 1. Why is the area around the edge so important and how exactly does a clear and continuous tone arise? 2. How can we influence a tone height by the force of blowing or by covering the end hole? 3. Why does the fujara have three holes and why are pipes with six holes also popular? 1. Formation of a continuous tone in a pipe Tone in a pipe arises because of the periodic reflection of pressure wave at the ends of the pipe. Unlike the reflection from the covered end, in case of the reflection from the open end (or from the end with a window) the wave reflects in anti-phase and part of it leaves the pipe. To get a continuous tone, we must constantly supply energy to the reflecting wave, just like we supply energy to a swing by pushing it. Unlike the swing where our reflexes are faster than its motion, the sound wave motion is too quick for our reflexes, which means that blowing air into the pipe has to be automated. -
The KNIGHT REVISION of HORNBOSTEL-SACHS: a New Look at Musical Instrument Classification
The KNIGHT REVISION of HORNBOSTEL-SACHS: a new look at musical instrument classification by Roderic C. Knight, Professor of Ethnomusicology Oberlin College Conservatory of Music, © 2015, Rev. 2017 Introduction The year 2015 marks the beginning of the second century for Hornbostel-Sachs, the venerable classification system for musical instruments, created by Erich M. von Hornbostel and Curt Sachs as Systematik der Musikinstrumente in 1914. In addition to pursuing their own interest in the subject, the authors were answering a need for museum scientists and musicologists to accurately identify musical instruments that were being brought to museums from around the globe. As a guiding principle for their classification, they focused on the mechanism by which an instrument sets the air in motion. The idea was not new. The Indian sage Bharata, working nearly 2000 years earlier, in compiling the knowledge of his era on dance, drama and music in the treatise Natyashastra, (ca. 200 C.E.) grouped musical instruments into four great classes, or vadya, based on this very idea: sushira, instruments you blow into; tata, instruments with strings to set the air in motion; avanaddha, instruments with membranes (i.e. drums), and ghana, instruments, usually of metal, that you strike. (This itemization and Bharata’s further discussion of the instruments is in Chapter 28 of the Natyashastra, first translated into English in 1961 by Manomohan Ghosh (Calcutta: The Asiatic Society, v.2). The immediate predecessor of the Systematik was a catalog for a newly-acquired collection at the Royal Conservatory of Music in Brussels. The collection included a large number of instruments from India, and the curator, Victor-Charles Mahillon, familiar with the Indian four-part system, decided to apply it in preparing his catalog, published in 1880 (this is best documented by Nazir Jairazbhoy in Selected Reports in Ethnomusicology – see 1990 in the timeline below). -

Secret Aerophones?
Secret Aerophones? The extent to which the contained air inside the body of an instrument is a dominant, even a predominant characteristic of its sound is something that has been concerning me for some time. It is not, so far as I know, something that has been studied in any detail, save spasmodically in a few special cases mentioned below. For example it can be demonstrated easily that slit drums, although nominally idiophones, function as giant Helmholtz resonators. If one strikes the drum while progressively occluding the slit with the hand, the pitch will drop as one reduces the area of open hole. This was first established by Raymond Clausen in his fieldwork on Malekula, when the people he was studying tried to produce a drum with the lowest possible sound by making the slit as large as possible, and discovered to their horror that the sound was much higher than usual. Stamping tubes are nominally idiophones but the pitch they produce when stamped on the ground is that of the contained air column. This can be demonstrated, as well as by listening to the type of sound, by blowing across the open end. The same may also be true of tubular bells, a type of idiophone that has not yet been adequately studied. The better made English hunting and coach horns produce the same pitch when struck as when blown; this is presumably done to reinforce their sound. New Guinea dance drums are clearly drums, but it is clear to the ear that the pitches they produce are those of the contained air column, not those of the membrane and that they also function as stamping tubes. -
Panpipes As Units of Cultural Analysis and Dispersal

E-mail: [email protected]; [email protected] Abstract The panpipe is a musical instrument composed of end-blown tubes of different lengths tied together. They can be traced back to the Neolithic, and they have been found at prehistoric sites in China, Europe and South America. Panpipes display substantial variation in space and time across functional and aesthetic dimensions. Finding similarities in panpipes that belong to distant human groups poses a challenge to cultural evolution: while some have claimed that their relative simplicity speaks for independent inven- tions, others argue that strong similarities of specific features in panpipes from Asia, Oceania and South America suggest long-distance diffusion events. We examined 20 features of a worldwide sample of 401 panpipes and analysed statistically whether instrument features can successfully be used to deter- mine provenance. The model predictions suggest that panpipes are reliable provenance markers, but we found an unusual classification error in which Melanesian panpipes are predicted as originating in South America. -

Prior research has focused on Western Revised: August 21, 2013 classical instruments, but no work has been published on ethnic wind instruments.

Results are presented in the context of a survey of prior studies, This work has not been peer providing a composite view of the intraoral pressure requirements of a broad reviewed. range of wind instruments. Mean intraoral pressure was 8.37 mBar across all ethnic wind instruments and 5.21 ± 2.16 mBar for Native American flutes. The range of pressure in Native American flutes closely matches pressure reported in Keywords: Intraoral pressure; Native other studies for normal speech, and the maximum intraoral pressure, 20.55 American flute; mBar, is below the highest subglottal pressure reported in other studies during Wind instruments; singing. Results show that ethnic wind instruments, with the exception of ethnic Velopharyngeal incompetency reed instruments, have generally lower intraoral pressure requirements than (VPI); Intraocular pressure (IOP) Western classical wind instruments. This implies a lower risk of the health issues related to high intraoral pressure. -
