Petals (composition)
''Petals'' is a piece of spectral music composed by Kaija Saariaho for cello and live electronics. It is one of the works studied in the Edexcel syllabus for the A-Level in Music. It has been recorded both by its dedicatee, Anssi Karttunen, on the Finlandia label and by the cellist Wilhelmina Smith on the Ondine label.Moisala, Pirkko and Diamond, Beverley (2000)''Music and Gender'' p. 187. University of Illinois Press. Mellor, Andrew (May 2019)"Review: Essa-Pekka Salonen, Kaija Saariaho: ''Works for Cello''" '' Gramophone Magazine''. Retrieved 1 May 2020. Background In 1982, Saariaho started studying at the Institute de Recherche et Coordination Acoustique/Musical in Paris. She focused her interests on computer-based sound spectrum analysis, electronic music, music combining live performance and electronics and the use of computers in the actual composition of music. ''Petals'' was written in 1988 over the course of a few days. It was performed for the first time in Bremen, by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectral Music
Spectral music uses the acoustic properties of sound – or sound spectra – as a basis for composition. Definition Defined in technical language, spectral music is an acoustic musical practice where compositional decisions are often informed by sonographic representations and mathematical analysis of sound spectra, or by mathematically generated spectra. The spectral approach focuses on manipulating the spectral features, interconnecting them, and transforming them. In this formulation, computer-based sound analysis and representations of audio signals are treated as being analogous to a timbral representation of sound. The (acoustic-composition) spectral approach originated in France in the early 1970s, and techniques were developed, and later refined, primarily at IRCAM, Paris, with the Ensemble l'Itinéraire, by composers such as Gérard Grisey and Tristan Murail. Hugues Dufourt is commonly credited for introducing the term ''musique spectrale'' (spectral music) in an ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glissando
In music, a glissando (; plural: ''glissandi'', abbreviated ''gliss.'') is a glide from one pitch to another (). It is an Italianized musical term derived from the French ''glisser'', "to glide". In some contexts, it is distinguished from the continuous portamento. Some colloquial equivalents are slide, sweep (referring to the "discrete glissando" effects on guitar and harp, respectively), bend, smear, rip (for a loud, violent gliss to the beginning of a note), lip (in jazz terminology, when executed by changing one's embouchure on a wind instrument), plop, or falling hail (a glissando on a harp using the back of the fingernails). On wind instruments, a scoop is a glissando ascending to the onset of a note achieved entirely with the embouchure. Portamento Prescriptive attempts to distinguish the glissando from the portamento by limiting the former to the filling in of discrete intermediate pitches on instruments like the piano, harp, and fretted stringed instruments have run u ...

Monophony
In music, monophony is the simplest of musical textures, consisting of a melody (or "tune"), typically sung by a single singer or played by a single instrument player (e.g., a flute player) without accompanying harmony or chords. Many folk songs and traditional songs are monophonic. A melody is also considered to be monophonic if a group of singers (e.g., a choir) sings the same melody together at the unison (exactly the same pitch) or with the same melody notes duplicated at the octave (such as when men and women sing together). If an entire melody is played by two or more instruments or sung by a choir with a fixed interval, such as a perfect fifth, it is also said to be monophony (or "monophonic"). The musical texture of a song or musical piece is determined by assessing whether varying components are used, such as an accompaniment part or polyphonic melody lines (two or more independent lines). In the Early Middle Ages, the earliest Christian songs, called plainchant (a we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromaticism
Chromaticism is a compositional technique interspersing the primary diatonic scale, diatonic pitch (music), pitches and chord (music), chords with other pitches of the chromatic scale. In simple terms, within each octave, diatonic music uses only seven different notes, rather than the twelve available on a standard piano keyboard. Music is chromatic when it uses more than just these seven notes. Chromaticism is in contrast or addition to tonality or diatonic and chromatic, diatonicism and modality (music), modality (the major scale, major and minor scale, minor, or "white key", scales). Chromatic elements are considered, "elaborations of or substitutions for diatonic scale members".Matthew Brown; Schenker, "The Diatonic and the Chromatic in Schenker's "Theory of Harmonic Relations", ''Journal of Music Theory'', Vol. 30, No. 1 (Spring 1986), pp. 1–33, citation on p. 1. Development of chromaticism Chromaticism began to develop in the late Renaissance music, Renaissance p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microtonal Music
Microtonal music or microtonality is the use in music of microtones—intervals smaller than a semitone, also called "microintervals". It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave. In other words, a microtone may be thought of as a note that falls between the keys of a piano tuned in equal temperament. In ''Revising the musical equal temperament,'' Haye Hinrichsen defines equal temperament as “the frequency ratios of all intervals are invariant under transposition (translational shifts along the keyboard), i.e., to be constant. The standard twelve-tone ''equal temperament'' (ET), which was originally invented in ancient China and rediscovered in Europe in the 16th century, is determined by two additional conditions. Firstly the octave is divided into twelve semitones. Secondly the octave, the most fundamental of all intervals, is postulated to be pure (beatless), as described by the ...

Tempo
In musical terminology, tempo (Italian, 'time'; plural ''tempos'', or ''tempi'' from the Italian plural) is the speed or pace of a given piece. In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and is usually measured in beats per minute (or bpm). In modern classical compositions, a "metronome mark" in beats per minute may supplement or replace the normal tempo marking, while in modern genres like electronic dance music, tempo will typically simply be stated in BPM. Tempo may be separated from articulation and meter, or these aspects may be indicated along with tempo, all contributing to the overall texture. While the ability to hold a steady tempo is a vital skill for a musical performer, tempo is changeable. Depending on the genre of a piece of music and the performers' interpretation, a piece may be played with slight tempo rubato or drastic variances. In ensembles, the tempo is often ind ...

Dynamics (music)
In music, the dynamics of a piece is the variation in loudness between notes or phrases. Dynamics are indicated by specific musical notation, often in some detail. However, dynamics markings still require interpretation by the performer depending on the musical context: for instance, the ''forte'' marking (meaning loud) in one part of a piece might have quite different objective loudness in another piece or even a different section of the same piece. The execution of dynamics also extends beyond loudness to include changes in timbre and sometimes tempo rubato. Purpose and interpretation Dynamics are one of the expressive elements of music. Used effectively, dynamics help musicians sustain variety and interest in a musical performance, and communicate a particular emotional state or feeling. Dynamic markings are always relative. never indicates a precise level of loudness; it merely indicates that music in a passage so marked should be considerably quieter than . There are ma ...

Pitch Shift
Pitch shifting is a sound recording technique in which the original pitch of a sound is raised or lowered. Effects units that raise or lower pitch by a pre-designated musical interval ( transposition) are called pitch shifters. Pitch and time shifting The simplest methods are used to increase pitch and reduce durations or, conversely, reduce pitch and increase duration. This can be done by replaying a sound waveform at a different speed than it was recorded. It could be accomplished on an early reel-to-reel tape recorder by changing the diameter of the capstan or using a different motor. As for vinyl records, placing a finger on the turntable to give friction will retard it, while giving it a "spin" can advance it. As technologies improved, motor speed and pitch control could be achieved electronically by servo drive system circuits.

Reverberation
Reverberation (also known as reverb), in acoustics, is a persistence of sound, after a sound is produced. Reverberation is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, their amplitude decreasing, until zero is reached. Reverberation is frequency dependent: the length of the decay, or reverberation time, receives special consideration in the architectural design of spaces which need to have specific reverberation times to achieve optimum performance for their intended activity. In comparison to a distinct echo, that is detectable at a minimum of 50 to 100 ms after the previous sound, reverberation is the occurrence of reflections that arrive in a sequence of less than approximately 50 ms. As time passes, the amplitude of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost the voltage or current (power, voltage or current amplifier). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorize ...

Double Stop
In music, a double stop is the technique of playing two notes simultaneously on a stringed instrument such as a violin, a viola, a cello, or a double bass. On instruments such as the Hardanger fiddle it is common and often employed. In performing a double stop, two separate strings are bowed or plucked simultaneously. Although the term itself suggests these strings are to be fingered (stopped), in practice one or both strings may be open. A triple stop is the same technique applied to three strings; a quadruple stop applies to four strings. Double, triple, and quadruple stopping are collectively known as multiple stopping. Early extensive examples of the double stop and string chords appear in Carlo Farina's ''Capriccio Stravagante'' from 1627, and in certain of the sonatas of Biagio Marini's Op. 8 of 1629. Bowing On instruments with a curved bridge, it is difficult to bow more than two strings simultaneously. Early treatises make it clear that composers did not expect three ...

Mordent
In music, a mordent is an ornament indicating that the note is to be played with ''a single'' rapid alternation with the note above or below. Like trills, they can be chromatically modified by a small flat, sharp or natural accidental. The term entered English musical terminology at the beginning of the 19th century, from the German ''Mordent'' and its Italian etymon, ''mordente'', both used in the 18th century to describe this musical figure. The word ultimately is derived from the Latin '' mordere'' (to bite). The ''mordent'' is thought of as a rapid single alternation between an indicated note, the note above (the ''upper mordent'') or below (the ''lower mordent'') and the indicated note again. The upper mordent is indicated by a short squiggle; the lower mordent is the same with a short vertical line through it: : As with the trill, the exact speed with which the mordent is performed will vary according to the tempo of the piece, but at a moderate tempo the above mig ...
