AbstractMusical instruments provide material evidence to study the diversity and technical innovation of music in space and time. We employed a cultural evolutionary perspective to analyse organological data and their relation to language groups and population history in South America, a unique and complex geographic area for human evolution. The ethnological and archaeological native musical instrument record, documented in three newly assembled continental databases, reveals exceptionally high diversity of wind instruments. We explored similarities in the collection of instruments for each population, considering geographic patterns and focusing on groupings associated with language families. A network analysis of panpipe organological features illustrates four regional/cultural clusters: two in the Tropical Forest and two in the Andes. Twenty-five percent of the instruments in the standard organological classification are present in the archaeological, but not in the ethnographic record, suggesting extinction events. Most recent extinctions can be traced back to European contact, causing a reduction in indigenous cultural diversity.

This paper offers a series of characterizations of prototypical musical timbres, called Timbre Trait Profiles, for 34 musical instruments common in Western orchestras and wind ensembles. These profiles represent the results of a study in which 243 musician participants imagined the sounds of various instruments and used the 20-dimensional model of musical instrument timbre qualia proposed by Reymore and Huron (2020) to rate their auditory image of each instrument. The rating means are visualized through radar plots, which provide timbral-linguistic thumbprints, and are summarized through snapshot profiles, which catalog the six highest- and three lowest-rated descriptors. The Euclidean distances among instruments offer a quantitative operationalization of semantic distances; these distances are illustrated through hierarchical clustering and multidimensional scaling. Exploratory Factor Analysis is used to analyze the latent structure of the rating data. Finally, results are used to assess Reymore and Huron’s 20-dimensional timbre qualia model, suggesting that the model is highly reliable. It is anticipated that the Timbre Trait Profiles can be applied in future perceptual/cognitive research on timbre and orchestration, in music theoretical analysis for both close readings and corpus studies, and in orchestration pedagogy.

Abstract Bird migration patterns are changing worldwide due to current global climate changes. Addressing the effects of such changes on the migration of birds in South America is particularly challenging because the details about how birds migrate within the Neotropics are generally not well understood. Here, we aim to infer the potential effects of future climate change on breeding and wintering areas of birds that migrate within South America by estimating the size and elevations of their future breeding and wintering areas. We used occurrence data from species distribution databases (VertNet and GBIF), published studies, and eBird for 3 thrush species (Turdidae; Turdus nigriceps, T. subalaris, and T. flavipes) that breed and winter in different regions of South America and built ecological niche models using ensemble forecasting approaches to infer current and future potential distributions throughout the breeding and wintering periods of each species. Our findings point to future shifts in wintering and breeding areas, mainly through elevational and longitudinal changes. Future breeding areas for T. nigriceps, which migrates along the Andes Mountains, will be displaced to the west, while breeding displacements to the east are expected for the other 2 species. An overall loss in the size of future wintering areas was also supported for 2 of the species, especially for T. subalaris, but an increase is anticipated for T. flavipes. Our results suggest that future climate change in South America will require that species shift their breeding and wintering areas to higher elevations in addition to changes in their latitudes and longitude. Our findings are the first to show how future climate change may affect migratory birds in South America throughout the year and suggest that even closely related migratory birds in South America will be affected in different ways, depending on the regions where they breed and overwinter.

"Meghalaya is a richly inhabited Indian state. Drums, flutes of bamboo and hand-held small cymbals are a common ensemble. The advent of Christianity in the middle of the 20th century marked the start of a decline in tribal popular music. Over time, Meghalaya’s music scene has evolved, attracting many talented artists and bands from both traditional and not-so traditional genres. Any of the most recent Meghalaya musicians and bands is: The Plague Throat, Kerios Wahlang, Cryptographik Street Poets, etc., Soulmate, Lou Majaw, and Snow White. Meghalaya’s music is characterised by traditional instruments and folk songs. The Musical Instruments of Meghalaya are made from local materials. Meghalayan people honour powerful natural forces and aim to pacify animistic spirits and local gods. The instruments are made of bamboo, flesh, wood, and animal horn. Any one of these musical instruments is considered to have the ability to offer material benefits. The Meghalaya musical instrument is an essential part of traditional folk music in the region. In this article, we offer an overview of the folk musical instruments of Meghalaya. Keywords: Idiophone, Aerophone, Chordophone, Membranophone, Trumpet. "

Insight Into

The article outlines the significance of Prussian military music of the 19th and early 20th centuries in an international context. It focuses on deliveries of musical instruments and sheet music by the Berlin company C. W. Moritz to Central and South America around 1900. The delivery lists of 1897/98 for the Colombian military bands show that they were equipped according to the Prussian model, which goes back to the ideas of Wilhelm Wieprecht. He reformed and standardised the Prussian military music system between the 1830s and 1860s, thus creating the basis for its success. The sheet music enclosed with the musical instruments gives an insight into the popular musical taste of the period around 1900, which was increasingly introduced to Central and South America. Future research will ask what impact such imports of music and musical instruments had on the development of music in Central and South America. (Vorlage)

Purpose This paper aims to discuss additive manufacturing (AM) in the context of applications for musical instruments. It examines the main AM technologies used in musical instruments, goes through a history of musical applications of AM and raises the questions about the application of AM to create completely new wind instruments that would be impossible to produce with conventional manufacturing. Design/methodology/approach A literature research is presented which covers a historical application of AM to musical instruments and hypothesizes on some potential new applications. Findings AM has found extensive application to create conventional musical instruments with unique aesthetics designs. It’s true potential to create entirely new sounds, however, remains largely untapped. Research limitations/implications More research is needed to truly assess the potential of additive manufacturing to create entirely new sounds for musical instrument. Practical implications The application of AM in music could herald an entirely new class of musical instruments with unique sounds. Originality/value This study highlights musical instruments as an unusual application of AM. It highlights the potential of AM to create entirely new sounds, which could create a whole new class of musical instruments.

This study explored advanced musicians’ dispositions to flow in musical practice. A total of 168 classically trained musicians answered a questionnaire assessing their proneness for flow experience during musical practice and associations between flow and demographic factors, practice routines and musical instruments. Dispositions to flow in musical practice did not vary across musical instrument groups, age or gender. Positive associations were found between daily practice time and flow, suggesting that flow may contribute to engagement with daily practice. Negative associations between music practice experience and loss of self-consciousness and challenge–skill balance were found, suggesting that even among experts the level of task complexity during practice may affect perceptions of competence. While six individual flow indicators were frequently experienced, three indicators were much less experienced, pointing to the existence of another similar relevant experience in the practice of expert performers, named as optimal practice experience. The article finishes with implications regarding the benefits of flow for teaching and learning practices.
