This corpus of text will benefit pianists and composers alike, and it provides the answers to the questions "what is a piano multiphonic", "what does a multiphonic sound like," and "how to notate a multiphonic sound". New terminology will be defined and inaccuracies in existing terminology will be dealt with. The multiphonic "mode of playing" will be separated from "playing technique" and from flageolets. Moreover, multiphonics in the repertoire are compared from the aspects of composition and notation, and the portability of multiphonics to the sounds of other instruments or to other mobile playing modes of the manipulated grand piano are examined. Composers tend to use multiphonics in a different manner, making for differing notational choices. This study examines notational choices and proposes a notation suitable for most situations, and notates the most commonly produceable multiphonic chords. The existence of piano multiphonics will be verified mathematically, supported by acoustic recordings and camera measurements. In my work, the correspondence of FFT analysis and hearing will be touched on, and by virtue of audio excerpts I offer ways to improve as a listener of multiphonics. It is observed that to produce of multiphonics the musician needs to have specialized knowledge, a small amount of technique and detailed instructions from the composer. Multiphonics are not impossible to produce, contrary to what a lack of prior literature would suggest.

Von der vorliegenden Texteinheit werden Pianisten und Komponisten gleichermaßen profitieren, und er bietet die Antworten auf die Fragen: "was ist ein Klaviermehrklang", "wie klingt ein Mehrklang" und "wie soll man einen Mehrklang notieren". Neue Vokabulär wird definiert und Ungenauigkeiten in der bisherigen Terminologie werden abgeschafft. Die multiphonische Spielart (mode of playing) wird von der Spieltechnik (playing technique) und den Flageolets getrennt. Darüber hinaus werden Mehrklänge im Repertoire anhand Aspekten der Komposition und der Notation verglichen, und kompositorische Übertragbarkeit in ähnlichen Klängen auf anderen Instrumenten oder auf den mobilen Spielarten (mobile modes of manipulated playing) des manipulierten Klaviers (manipulated grand piano) werden ausgelotet. Mehrklänge werden von Komponisten in verschiedensten Weisen benutzt, wodurch die notationellen Lösungen sich auch unterscheiden. Diese Studie untersucht Notationsweisen und wird eine für die meisten Fällen geeignete Notation vorschlagen ebenso wie die am häufigsten vorkommenden Mehrklänge in Notation eintragen. Das Bestehen der Klaviermehrklänge wird mathematisch nachgewiesen, sowie mit Tonaufzeichnungen und Kameramessungen. In meiner Arbeit berühre ich an der Übereinstimmung der FFT-Analyse und des Gehörten und biete durch Klangbeispielen Mittel dafür, sich as Zuhörer der Mehrklänge zu verbessern. Es wird festgestellt, dass Mehrklänge zu produzieren vom Pianisten kognitive Besonderfähigkeiten und einiges technisches Können, und vom Komponisten detaillierte Anweisungen erfordert. Es ist nicht unmöglich, Mehrklänge zu erzeugen, obwohl die Mangel an vorhandener Literatur darauf hinweisen würde.

Tekstikokonaisuudesta on yhtäläistä hyötyä pianistille ja säveltäjälle, ja se tarjoaa vastauksen kysymyksiin "mikä on pianon multifoni", "miltä multifoni kuulostaa" ja "miten multifoni nuotinnetaan". Uutta sanastoa määritellään ja aiemman terminologian epätarkkuuksia karsitaan. Multifonien soittotapa (mode of playing) erotetaan soittotekniikasta (playing technique) ja huiluäänistä (flageolets). Lisäksi vertaillaan multifoneja sisältävää ohjelmistoa sävellyksellisistä ja nuotinnuksen näkökulmista sekä tutkitaan multifonien sävellyksellistä siirrettävyyttä muiden soittimien samankaltaisiin ääniin tai muokatun pianon (manipulated grand piano) muihin liikkuviin soittotapoihin (mobile modes of manipulated playing). Säveltäjät käyttävät multifoneja eri tavoin, joten myös nuotinnusratkaisut eroavat. Työssä tarkastellaan notaatiotapoja ja tehdään ehdotus useimpiin tilanteisiin sopivasta notaatiosta sekä nuotinnetaan yleisimmin tuotettavat multifonisoinnut. Pianon multifonien olemassaolo todennetaan paitsi matemaattisesti, myös akustisten äänitysten ja kameramittausten avulla. Työssäni sivuan FFT-analyysin ja kuulokuvan vastaavuutta ja ääniesimerkein tarjoan keinoja harjaantua multifonien kuulijana. Todetaan, että multifonien tuottaminen vaatii soittajaltaan tiedollista erikoisosaamista ja hieman tekniikkaa sekä säveltäjältä tarkkaa ohjeistusta. Multifoneja ei ole mahdotonta tuottaa, kuten aiemman kirjallisuuden vähyydestä voisi päätellä.

There are many excellent piano-tuning applications available (both for free and for charge). This one is designed to also demonstrate a little music theory (and physics for the ‘engineer’ in all of us). It displays and helps interpret the full audio spectra produced when striking a piano key, including its harmonics. Since it does not lock in on the primary note struck (like many other tuners do), you can tune the interval between two keys by examining the spectral regions where their harmonics should overlap in frequency. You can also clearly see (and measure) the inharmonicity driving ‘stretch’ tuning (where the spacing of real-string harmonics is not constant, but increases with higher harmonics). The tuning sequence described here effectively incorporates your piano’s specific inharmonicity directly, key by key, (and makes it visually clear why choices have to be made). You can also use a (very) simple calculated stretch if desired. Other tuner apps have pre-defined stretch curves available (or record keys and then algorithmically calculate their own). Some are much more sophisticated indeed! B) Graphical User Interface elements defined A) Complete interface.

The egg masses were kept in the same relative place in which they were laid, and protected by plastic containers with two mesh sides to let the water flow freely past the eggs. Samples of the egg masses were collected and observed under a microscope at regular intervals while temperature, salinity, width of eggs and stage of development were recorded. It was found that each embryo developed significantly faster compared to previous studies conducted on the respective species’ egg masses, including studies with higher water temperatures.

Müzik besteci tarafından yazılır. Besteci yaratıcılığını, imkanlar çerçevesinde kullanacağı çalgı ya da çalgı gruplarının teknik ve fiziksel özelliklerini dikkate alarak neticelendirir. Bu bir gereksinimdir. Bu gereksinim 20. yüzyılın başlarında kültürel, siyasal ve teknolojik gelişmeler paralelinde en hareketli ve bekli de en yaratıcı seviyelere ulaşmıştır. Çalgısal tekniklerin ve yeni ses kaynaklarının gelişimi, yeni yazım ve çalım tekniklerini de beraberinde getirmiştir. Bu dönemde yaşayan besteciler eserlerinde çalgılardan o ana kadar var olan tınıların dışında farklı tınılar ve renkler elde etme arayışına girmiş, bir grup besteci de geçmişten gelen mirası ret ederek elektronik tekniklerle geliştirilmiş yeni çalgıların yapımına ve bu çalgılardan farklı sesler elde etme çabasına girmişlerdir. Yeni çalgılar yaratma fikri bir yana var olan çalgılardan yeni tınılar elde etme çabası, beraberinde klasik notalamadan farklı bir notalama biçiminin ortaya çıkmasına sebebiyet vermiştir. Bu dönemde, yeniyi arama ve bulunan yenilikleri uygulama sadece besteciler tarafından değil aynı zamanda birçok solist çalgıcının kendi çalgısının ses kabiliyetini belirleme ve keşfetmesiyle de en yüksek seviyelerine ulaşmıştır.

  • Developments in Extended Vocal Technique Music
    PART ONE Fundamental Techniques Part One – Fundamental Techniques In his essay Sprech und Gesangsschule (Neue Vokalpratiken) (School for Speech and Singing (New Vocal Practices)) (1972), the German composer and theologian Dieter Schnebel provides a thorough and innovative investigation into the production, usage and latent possibilities of new vocal techniques. Schnebel comments on the inherent limitations of conventional vocal performance practices and notations and their relative inaccuracy and unsuitability when applied to extended vocal techniques. He goes on to outline the main physical mechanisms and processes involved in the production of vowels and consonants, suggesting new ways in which to expand the range of attainable sounds through the combination of various mouth (vowel) positions with different noise (consonant) sounds. He discusses the importance of breath control in the shaping of these sounds, as well as the actual use of various modes of breath as compositional material, stating that ‘Audible and inaudible breath processes would, so to speak, form the basis of the artistic processes... Breath, crossing the line of audibility, becomes art itself, built from shaped fricatives’1 However, such techniques are seen not only as processes with which to create new sounds but also as a means of liberating both the voice and the consciousness of the performer. Schnebel writes: ‘Such operations lead, so to speak, into the sound production itself. Taken further, they can themselves attain form, without the overlapping unities like words or even sentences being adjusted. That is, the articulation process becomes the object of the composition...This demands a conscious knowledge of what is happening with the articulation’2 With reference to his composition Maulwerke he adds: ‘...the content is expressed no longer mediated through the vehicle of a still rudimentary text, but rather directly.

    /VB3 / A/ O,(s0-02 A SURVEY OF THE RESEARCH LITERATURE ON THE FEMALE HIGH VOICE THESIS Presented to the Graduate Council of the University of North Texas in Partial Fulfillment of the Requirements For the Degree of MASTER OF ARTS By Roberta M. Stephen, B. Mus., A. Mus., A.R.C.T. Denton, Texas December, 1988 Stephen, Roberta M., Survey of the Research Literature on the Female High Voice. Master of Arts (Music), December, 1988, 161 pp., 11 tables, 13 illustrations, 1 appendix, bibliography, partially annotated, 136 titles. The location of the available research literature and its relationship to the pedagogy of the female high voice is the subject of this thesis. The nature and pedagogy of the female high voice are described in the first four chapters. The next two chapters discuss maintenance of the voice in conventional and experimental repertoire. Chapter seven is a summary of all the pedagogy. The last chapter is a comparison of the nature and the pedagogy of the female high voice with recommended areas for further research. For instance, more information is needed to understand the acoustic factors of vibrato, singer's formant, and high energy levels in the female high voice. PREFACE The purpose of this thesis is to collect research about the female high voice and to assemble the pedagogy. The science and the pedagogy will be compared to show how the two subjects conform, where there is controversy, and where more research is needed. Information about the female high voice is scattered in various periodicals and books; it is not easily found.
