Spectral Glide
A spectral glide is a music-composition concept, consisting of a "modification of the vowel quality of a tone" (Erickson 1975, p. 72). Since the vowel quality of a tone is determined by the overtones, spectrum, or timbre of that tone (all three terms describe approximately the same hearing experience), a spectral glide is a move from a spectrum characteristic of one vowel to a spectrum characteristic of another vowel. A spectral glide may be accomplished through a wah-wah, mute, or pedal, or through the modification of one's vocal tract while speaking, singing, or playing an instrument such as the didgeridoo. Lip-vibrated instruments with large mouthpieces such as tuba and trombone allow extensive modification of vowel quality, while woodwinds have a smaller range, with the exception of the flute in air-sound mode. Strings have the smallest range (Erickson 1975, p. 72). The glide rate and the vowel contrasts used are important factors in the compositional use of spect ...

Vowel Quality
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress. The word ''vowel'' comes from the Latin word , meaning "vocal" (i.e. relating to the voice). In English, the word ''vowel'' is commonly used to refer both to vowel sounds and to the written symbols that represent them (a, e, i, o, u, and sometimes y). Definition There are two complementary definitions of vowel, one phonetic and the other phonological. *In the phonetic definition, a vowel is a sound, such as the English "ah" or "oh" , produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and continuant. ...

Brass Instrument
A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones or labrophones, from Latin and Greek elements meaning 'lip' and 'sound'. There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks (though they are rarely used today), or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from the available series. The view of most scholars (see organology) is that the term "brass instrument" should be defined by the way the sound is made, as above, and not by whether the instrument is actually made of brass. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent and the didgeridoo, while some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subtractive Synthesis
Subtractive synthesis is a method of sound synthesis in which partials of an audio signal (often one rich in harmonics) are attenuated by a filter to alter the timbre of the sound. While subtractive synthesis can be applied to any source audio signal, the sound most commonly associated with the technique is that of analog synthesizers of the 1960s and 1970s, in which the harmonics of simple waveforms such as sawtooth, pulse or square waves are attenuated with a voltage-controlled resonant low-pass filter. Many digital, virtual analog and software synthesizers use subtractive synthesis, sometimes in conjunction with other methods of sound synthesis. Examples of subtractive synthesis A human example The basis of subtractive synthesis can be understood by considering the human voice; when a human speaks, sings or makes other vocal noises, the vocal folds act as an oscillator and the mouth and throat as a filter. Consider the difference between singing "oooh" and "aaah" , a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muted Trumpet
A mute is a device attached to a musical instrument which changes the instrument's tone quality (timbre) or lowers its volume. Mutes are commonly used on string and brass instruments, especially the trumpet and trombone, and are occasionally used on woodwinds. Their effect is mostly intended for artistic use, but they can also allow players to practice discreetly. Muting can also be done by hand, as in the case of palm muting a guitar or grasping a triangle to dampen its sound. Mutes on brass instruments are typically inserted into the flared end of the instrument (bell). They can also be held in front of or clipped onto the bell. Of brass mutes, the "straight mute" is the most common and is frequently used in classical and jazz music, but a wide variety are available. On string instruments of the violin family, mutes are usually attached to the bridge, the piece of wood that supports the strings. Palm muting a guitar involves placing the side of the hand across the strings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Punkte
''Punkte'' (Points) is an orchestral composition by Karlheinz Stockhausen, given the work number ½ in his catalogue of works. History ''Punkte'' originated as a punctual orchestral work which was begun in September in Hamburg and had reached a first-draft stage by 30 September. The final draft was completed on 24 October 1952, but the work remained unperformed and unpublished . The work did not receive the title by which it is known today until much later, however. In a letter dated 4 November 1952 to (the editor from Universal Edition in Vienna who, at the premiere of Stockhausen's ''Spiel'' at the Donaueschingen Festival in October, had offered to publish his works), Stockhausen initially called his new score ''Zweites Orchesterspiel / Kontrapunkte / für Saiten- und Blasinstrumente'', and in a letter to his friend Karel Goeyvaerts dated 14 January 1953, he calls the orchestral work ''Nr. 4 Kontrapunkte'', adding, "It will be very difficult to perform this work".

Karlheinz Stockhausen
Karlheinz Stockhausen (; 22 August 1928 – 5 December 2007) was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. He is known for his groundbreaking work in electronic music, for introducing controlled chance ( aleatory techniques) into serial composition, and for musical spatialization. He was educated at the Hochschule für Musik Köln and the University of Cologne, later studying with Olivier Messiaen in Paris and with Werner Meyer-Eppler at the University of Bonn. One of the leading figures of the Darmstadt School, his compositions and theories were and remain widely influential, not only on composers of art music, but also on jazz and popular music. His works, composed over a period of nearly sixty years, eschew traditional forms. In addition to electronic music—both with and without live performers—they range from miniatures for musical boxes through works for s ...

Didgeridoo
The didgeridoo (; also spelt didjeridu, among other variants) is a wind instrument, played with vibrating lips to produce a continuous drone while using a special breathing technique called circular breathing. The didgeridoo was developed by Aboriginal peoples of northern Australia at least 1,000 years ago, and is now in use around the world, though still most strongly associated with Indigenous Australian music. In the Yolŋu languages of the indigenous people of northeast Arnhem Land the name for the instrument is the ''yiḏaki'', or more recently by some, ''mandapul''. In the Bininj Kunwok language of West Arnhem Land it is known as ''mako''. A didgeridoo is usually cylindrical or conical, and can measure anywhere from long. Most are around long. Generally, the longer the instrument, the lower its pitch or key. Flared instruments play a higher pitch than unflared instruments of the same length. History There are no reliable sources of the exact age of the didgeridoo. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musical Tone
Traditionally in Western music, a musical tone is a steady periodic sound. A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation. A simple tone, or pure tone, has a sinusoidal waveform. A complex tone is a combination of two or more pure tones that have a periodic pattern of repetition, unless specified otherwise. The Fourier theorem states that any periodic waveform can be approximated as closely as desired as the sum of a series of sine waves with frequencies in a harmonic series and at specific phase relationships to each other. The common denominator frequency, which is also often the lowest of these frequencies is the fundamental frequency, and is also the inverse of the period of the waveform. The fundamental frequency determines the pitch of the tone, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vocal Tract
The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx (biology), syrinx in birds) is filtered. In birds it consists of the Vertebrate trachea, trachea, the Syrinx (biology), syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity. The estimated average length of the vocal tract in adult male humans is 16.9 cm and 14.1 cm in adult females.

Wah-wah Pedal
A wah-wah pedal, or simply wah pedal, is a type of electric guitar effects pedal that alters the tone and frequencies of the guitar signal to create a distinctive sound, mimicking the human voice saying the onomatopoeic name "wah-wah". The pedal sweeps the peak response of a frequency filter up and down in frequency to create the sound, a spectral glide, also known as "the wah effect". The wah-wah effect originated in the 1920s, with trumpet or trombone players finding they could produce an expressive crying tone by moving a mute in and out of the instrument's bell. This was later simulated with electronic circuitry for the electric guitar when the wah-wah pedal was invented. It is controlled by movement of the player's foot on a rocking pedal connected to a potentiometer. Wah-wah effects may be used as a fixed-filter to alter an instrument’s timbre (known as a “cocked-wah”); they may be used when a guitarist is soloing; or, classically, they may be used to create a "wa ...
