Shepard Tones
A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the ''Shepard scale''. This creates the auditory illusion of a tone that seems to continually ascend or descend in pitch, yet which ultimately gets no higher or lower. Construction Each square in Figure 1 indicates a tone, with any set of squares in vertical alignment together making one Shepard tone. The color of each square indicates the loudness of the note, with purple being the quietest and green the loudest. Overlapping notes that play at the same time are exactly one octave apart, and each scale fades in and fades out so that hearing the beginning or end of any given scale is impossible. As a conceptual example of an ascending Shepard scale, the first tone could be an almost inaudible C4 (middle C) and a loud C5 (an octave higher). The next would be a slig ...

Staccato
Staccato (; Italian for "detached") is a form of musical articulation. In modern notation, it signifies a note of shortened duration, separated from the note that may follow by silence. It has been described by theorists and has appeared in music since at least 1676. Notation In 20th-century music, a dot placed above or below a note indicates that it should be played staccato, and a wedge is used for the more emphatic staccatissimo. However, before 1850, dots, dashes, and wedges were all likely to have the same meaning, even though some theorists from as early as the 1750s distinguished different degrees of staccato through the use of dots and dashes, with the dash indicating a shorter, sharper note, and the dot a longer, lighter one. A number of signs came to be used in the late 19th and early 20th centuries to discriminate more subtle nuances of staccato. These signs involve various combinations of dots, vertical and horizontal dashes, vertical and horizontal wedges, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diana Deutsch
Diana Deutsch (born 15 February 1938) is a British-American psychologist from London, England. She's a Professor of Psychology at the University of California, San Diego, and is a prominent researcher on the psychology of music. Deutsch is primarily known for her discoveries in music and speech illusions. She also studies the cognitive foundation of musical grammars, which consists of the way people hold musical pitches in memory, and how people relate the sounds of music and speech to each other. In addition, she is known for her work on absolute pitch (perfect pitch), which she has shown is far more prevalent among speakers of tonal languages. Deutsch is the author of ''Musical Illusions and Phantom Words: How Music and Speech Unlock Mysteries of the Brain'' (2019), the ''Psychology of Music'', and also the compact discs ''Musical Illusions and Paradoxes'' (1995) and ''Phantom Words and Other Curiosities'' (2003).

Necker Cube
The Necker cube is an optical illusion that was first published as a Rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. It is a simple wire-frame, two dimensional drawing of a cube with no visual cues as to its orientation, so it can be interpreted to have either the lower-left or the upper-right square as its front side. Ambiguity The Necker cube is an ambiguous drawing. Each part of the picture is ambiguous by itself, yet the human visual system picks an interpretation of each part that makes the whole consistent. The Necker cube is sometimes used to test computer models of the human visual system to see whether they can arrive at consistent interpretations of the image the same way humans do. Humans do not usually see an inconsistent interpretation of the cube. A cube whose edges cross in an inconsistent way is an example of an impossible object, specifically an impossible cube (compare Penrose triangle). With the cube on the left, most people see the lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tritone Paradox
__NOTOC__ The tritone paradox is an auditory illusion in which a sequentially played pair of Shepard tones separated by an interval of a tritone, or half octave, is heard as ascending by some people and as descending by others. Different populations tend to favor one of a limited set of different spots around the chromatic circle as central to the set of "higher" tones. Roger Shepard in 1963 had argued that such tone pairs would be heard ambiguously as either ascending or descending. However, psychology of music researcher Diana Deutsch in 1986 discovered that when the judgments of individual listeners were considered separately, their judgments depended on the positions of the tones along the chromatic circle. For example, one listener would hear the tone pair C–F as ascending and the tone pair G–C as descending. Yet another listener would hear the tone pair C–F as descending and the tone pair G–C as ascending. Furthermore, the way these tone pairs were perceived varied ...

Tritone
In music theory, the tritone is defined as a musical interval composed of three adjacent whole tones (six semitones). For instance, the interval from F up to the B above it (in short, F–B) is a tritone as it can be decomposed into the three adjacent whole tones F–G, G–A, and A–B. Narrowly defined, each of these whole tones must be a step in the scale, so by this definition, within a diatonic scale there is only one tritone for each octave. For instance, the above-mentioned interval F–B is the only tritone formed from the notes of the C major scale. More broadly, a tritone is also commonly defined as any interval with a width of three whole tones (spanning six semitones in the chromatic scale), regardless of scale degrees. According to this definition, a diatonic scale contains two tritones for each octave. For instance, the above-mentioned C major scale contains the tritones F–B (from F to the B above it, also called augmented fourth) and B–F (from B to the F abo ...

Interval (music)
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. In Western music, intervals are most commonly differences between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C and D. Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic freq ...

Risset Accelerando Beat1 MCLD
Jean-Claude Raoul Olivier Risset (; 13 March 1938 – 21 November 2016) was a French composer, best known for his pioneering contributions to computer music. He was a former student of André Jolivet and former co-worker of Max Mathews at Bell Labs. Biography Risset was born in Le Puy-en-Velay, France. Arriving at Bell Labs, New Jersey in 1964, he used Max Mathews' MUSIC IV software to digitally recreate the sounds of brass instruments. He made digital recordings of trumpets and studied their timbral composition using "pitch-synchronous" spectrum analysis tools, revealing that the amplitude and frequency of the harmonics (more correctly, partials) of these instruments would differ depending on frequency, duration and amplitude. He is also credited with performing the first experiments on a range of synthesis techniques including FM synthesis and waveshaping. After the discrete Shepard scale Risset created a version of the scale where the steps between each tone are continuou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
