Erich Moritz Von Hornbostel
Erich Moritz von Hornbostel (25 February 1877 – 28 November 1935) was an Austrian ethnomusicologist and scholar of music. He is remembered for his pioneering work in the field of ethnomusicology, and for the Sachs–Hornbostel system of musical instrument classification which he co-authored with Curt Sachs. Life Hornbostel was born in Vienna into a musical family. The House of Hornbostel is a Saxon nobility. He studied the piano, harmony and counterpoint as a child, but his PhD at the University of Vienna was in chemistry. He moved to Berlin, where he fell under the influence of Carl Stumpf and worked with him on musical psychology and psychoacoustics. He was Stumpf's assistant at the Berlin Psychological Institute, and when the archives of the Institute were used as the basis for the Berliner Phonogramm-Archiv, he became its first director in 1905. It was during his time there that he worked with Curt Sachs to produce the Sachs–Hornbostel system of musical instrument cla ...

Cambridge
Cambridge ( ) is a College town, university city and the county town in Cambridgeshire, England. It is located on the River Cam approximately north of London. As of the 2021 United Kingdom census, the population of Cambridge was 145,700. Cambridge became an important trading centre during the Roman and Viking ages, and there is archaeological evidence of settlement in the area as early as the Bronze Age. The first Town charter#Municipal charters, town charters were granted in the 12th century, although modern city status was not officially conferred until 1951. The city is most famous as the home of the University of Cambridge, which was founded in 1209 and consistently ranks among the best universities in the world. The buildings of the university include King's College Chapel, Cambridge, King's College Chapel, Cavendish Laboratory, and the Cambridge University Library, one of the largest legal deposit libraries in the world.

Max Wertheimer
Max Wertheimer (April 15, 1880 – October 12, 1943) was an Austro-Hungarian psychologist who was one of the three founders of Gestalt psychology, along with Kurt Koffka and Wolfgang Köhler. He is known for his book, ''Productive Thinking'', and for conceiving the phi phenomenon as part of his work in Gestalt psychology. Wertheimer became interested in psychology and studied under Carl Stumpf at the University of Berlin.Hothersall, D. (2003) Wertheimer then went on to obtain his PhD in 1904 under Oswald Külpe, at the University of Würzburg and then began his intellectual career teaching at the Institute for Social Research at Frankfurt University. For a short time, he left Frankfurt to work at the Berlin Psychological Institute, but returned in 1929 as a full professor. Wertheimer eventually joined the faculty of The New School in New York, a position he held until his death. Early life Max Wertheimer was born on April 15, 1880, in Prague, then part of the Bohemian Austria-H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Localization
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or intensity difference) between the ears, and spectral information. These cues are also used by other animals, such as birds and reptiles, but there may be differences in usage, and there are also localization cues which are absent in the human auditory system, such as the effects of ear movements. Animals with the ability to localize sound have a clear evolutionary advantage. How sound reaches the brain Sound is the perceptual result of mechanical vibrations traveling through a medium such as air or water. Through the mechanisms of compression and rarefaction, sound waves travel through the air, bounce off the pinna and concha of the exter ...

Interaural Time Difference
The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears. It is important in the localization of sounds, as it provides a cue to the direction or angle of the sound source from the head. If a signal arrives at the head from one side, the signal has further to travel to reach the far ear than the near ear. This pathlength difference results in a time difference between the sound's arrivals at the ears, which is detected and aids the process of identifying the direction of sound source. When a signal is produced in the horizontal plane, its angle in relation to the head is referred to as its azimuth, with 0 degrees (0°) azimuth being directly in front of the listener, 90° to the right, and 180° being directly behind. Different methods for measuring ITDs *For an abrupt stimulus such as a click, onset ITDs are measured. An onset ITD is the time difference between the onset of the signal reaching two ea ...

Anthropology
Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, societies, and linguistics, in both the present and past, including past human species. Social anthropology studies patterns of behavior, while cultural anthropology studies cultural meaning, including norms and values. A portmanteau term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological or physical anthropology studies the biological development of humans. Archaeological anthropology, often termed as 'anthropology of the past', studies human activity through investigation of physical evidence. It is considered a branch of anthropology in North America and Asia, while in Europe archaeology is viewed as a discipline in its own right or grouped under other related disciplines, such as history and palaeontology. Etymology The abstract noun '' anthropology'' is first attested in refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musical Tuning
In music, there are two common meanings for tuning: * Tuning practice, the act of tuning an instrument or voice. * Tuning systems, the various systems of pitches used to tune an instrument, and their theoretical bases. Tuning practice Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A = 440 Hz. The term "''out of tune''" refers to a pitch/tone that is either too high (sharp) or too low ( flat) in relation to a given reference pitch. While an instrument might be in tune relative to its own range of notes, it may not be considered 'in tune' if it does not match the chosen reference pitch. Some instruments become 'out of tune' with temperature, humidity, damage, or simply time, and must be readjusted or repaired. Different methods of sound production require different methods of adjustment: * Tuning to a pitch with one's voi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klaus Wachsmann
Klaus Philipp Wachsmann (8 March 1907 – 17 July 1984) was a British ethnomusicologist of German birth. Born in 1907 in Berlin, he is considered a pioneer in the study of the traditional musics of Africa. His studies in Germany (on pre-Gregorian chant under mentor Erich von Hornbostel) were interrupted by the rise of the Nazis in 1933, where he was also forbidden to marry his 'Aryan' fiancée Eva Buttenburg, a singer. Consequently they both migrated to Britain in 1936.Oldfield, Sybil. ''The Black Book: The Britons on the Nazi Hit List'' (2020), p.233-4 While in the UK Wachsmann gained funding by the Society for the Protection of Science and Learning to study African languages at the School of Oriental and African Studies in London. His wife worked as a voice coach. With help from the Church Missionary Society they then moved to Uganda in 1937, where Wachsmann compiled an extensive collection of field recordings between 1949 and 1952. The full collection was originally deposited a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
