Tonograph
The tonograph ( it, tonografo) is a device invented by Italian scientist Luca de Samuele Cagnazzi (1764-1852) and presented at the ''Terza riunione degli scienziati italiani'' (the "Third Meeting of Italian Scientists"), held in Florence in September 1841. The original device was donated by its inventor Cagnazzi during the Third Meeting of Italian Scientists. After then, the instrument went lost, but in 1932 ca., thanks to the work of a scholar, it was found in a cellar and exhibited at the Museo Galileo, located in ''Piazza dei Giudici'', Florence. The original device is now stored in the ''Museo Nazionale Scienza e Tecnologia Leonardo da Vinci'', Milan. A copy of the device was commissioned by Count Celio Sabini (from Altamura) and it's now displayed at the museum '' Archivio Biblioteca Museo Civico'', located in Altamura. Making According to Luca de Samuele Cagnazzi's unpublished autobiography ''La mia vita'', the tonograph was made by Cagnazzi himself with his own hands ...

Luca De Samuele Cagnazzi
Luca de Samuele Cagnazzi (28 October 1764 – 26 September 1852) was an Italian archdeacon, scientist, mathematician, political economist. He also wrote a book about pedagogy and invented the tonograph. Life Born at Altamura, in what is now Apulia, he taught mathematics and physics in the University of Altamura under the rectorship of Msgr. Gioacchino de Gemmis. In 1799 he first moved to Florence, where he worked as a teacher and then he moved to the University of Naples Federico II where he became a professor of statistics and of economics, and a member of the Royal Society of Encouragement to Natural Sciences of Naples. He also became head of the Office of Statistics and Trade of the Kingdom of Naples, under Joachim Murat's rule, and he kept that position until 1821. He was a frequent contributor to the Italian journal ''Il progresso delle scienze, delle lettere e delle arti'', of which he was also editor for a short time. In 1848, at age of 84, he was elected memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archivio Biblioteca Museo Civico
The Archivio Biblioteca Museo Civico (also A.B.M.C.) is an organization which mainly serves as library and museum and it is located in Altamura, Italy. The archive and library comprise about 90,000 books, mostly about history and literature, among which are scrolls and books dating back to Middle Ages and the 16th century. A.B.M.C. also includes books from the former city library ''Biblioteca Comunale'', replaced by A.B.M.C. in ca. 1950. The number of books has dramatically increased over the years. The library stores valuable books and archeological finds, such as the cofanetto limosino, the tonograph and both ancient and modern art paintings. It also stores some bone fragments believed to have been from Dante Alighieri's hand. Indro Montanelli also mentioned it in his book ''Dante Alighieri'' (booklet number 4 of series “I Protagonisti”, published and sold in 1993 together with Italian newspaper ''Il Giornale ''il Giornale'' ( en, The Newspaper) is an Italian language d ...

Declamation
Declamation (from the Latin: ''declamatio'') is an artistic form of public speaking. It is a dramatic oration designed to express through articulation, emphasis and gesture the full sense of the text being conveyed. History In Ancient Rome, declamation was a genre of ancient rhetoric and a mainstay of the Roman higher education system. It was separated into two component subgenres, the ''controversia'', speeches of defense or prosecution in fictitious court cases, and the ''suasoria'', in which the speaker advised a historical or legendary figure as to a course of action. Roman declamations survive in four corpora: the compilations of Seneca the Elder and Calpurnius Flaccus, as well as two sets of ''controversiae'', the ''Major Declamations'' and ''Minor Declamations'' spuriously attributed to Quintilian. Declamation had its origin in the form of preliminary exercises for Greek students of rhetoric: works from the Greek declamatory tradition survive in works such as the collectio ...

Harmonic Scale
The harmonic scale is a "super-just" musical scale allowing extended just intonation, beyond 5- limit to the 19th harmonic (), and free modulation through the use of synthesizers. Transpositions and tuning tables are controlled by the left hand on the appropriate note on a one-octave keyboard.Milano, Dominic (November 1986)"A Many-Colored Jungle of Exotic Tunings" ''Keyboard''. For example, if the harmonic scale is tuned to a fundamental of C, then harmonics 16–32 are as follows: Some harmonics are not included: 23, 25, 29, & 31. The 21st is a natural seventh above G, but not a great interval above C, and the 27th is a just fifth above D. It was invented by Wendy Carlos and used on three pieces on her album ''Beauty in the Beast'' (1986): ''Just Imaginings'', ''That's Just It'', and ''Yusae-Aisae''. Versions of the scale have also been used by Ezra Sims, Franz Richter Herf and Gosheven. Number of notes Though described by Carlos as containing " 144 122distin ...

Diatonic Scale
In music theory, a diatonic scale is any heptatonic scale that includes five whole steps (whole tones) and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps, depending on their position in the scale. This pattern ensures that, in a diatonic scale spanning more than one octave, all the half steps are Maximal evenness, maximally separated from each other (i.e. separated by at least two whole steps). The seven pitch (music), pitches of any diatonic scale can also be obtained by using a Interval cycle, chain of six perfect fifths. For instance, the seven natural (music), natural pitch classes that form the C-major scale can be obtained from a stack of perfect fifths starting from F: :F–C–G–D–A–E–B Any sequence of seven successive natural notes, such as C–D–E–F–G–A–B, and any Transposition (music), transposition thereof, is a diatonic scale. Modern musical keyboards are des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times a minute (2 hertz), the period, —the interval at which the beats repeat—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. Definitions and units For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term ''frequency'' is defined as the number of cycles or vibrations per unit of time.

Phonatory
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, ''phonation'' is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process '' voicing'', and use the term ''phonation'' to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. Voiceless and supra-glottal phonations are included under this definition. Voicing The phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufficiently large, the vocal folds start to oscillate. The minimum pressure drop required to achieve phonation is called the phonation threshold ...
