This thesis is an examination about different keyboard instruments and how the pianist can use them in a groove context. All keyboard instruments have different attack, decay, release, overtones, and dynamics, as well as different opportunities to affect these parameters. Every instrument also involves various opportunities and challenges in an ensemble, in the way they affect and are affected by the playing of the fellow musicians. The examination involved that I played, recorded, and transcribed different keyboard patterns from different recordings. I played every pattern with four different instruments and explored how the groove changed based on the instruments I played and how I could use the parameters of every instrument to get variation. First, I did this playing to drum loops and later with real musicians.   My conclusions are that getting an overview of the overtones and how distinct the instruments can be is the key to improve your ability to play different keyboard instruments. To get to know instruments and their ways to express intensity is the essence of finding your way into the groove.

At the Edinburgh University Collection of Historical Instruments (EUCHMI) there are two virginals where the strings are plucked extremely close to 1/4 of their length over a substantial part of the compass. Principles of Acoustics dictate that in such cases the fourth partial of the resulting sound is unlikely to be produced with any appreciable magnitude. Similar situations affecting different partials also occur when the plucking point is located at other fractional parts of the string length, such as 1/3 or 1/5. A database of plucking points, based on museum catalogues, was created and analysed, so that pitch regions are identified where such phenomena are likely to occur for different categories of instruments. The main cue used in harpsichord tuning is related to beat phenomena produced by partials of two simultaneously played notes, whenever there is a small difference between their frequencies. Partial four being relevant for major thirds and perfect fourths, these intervals may result less accurate, or less reliably tuned, in instruments like the above virginals. Historical sources were surveyed for expressions which describe the cues that tuners were supposed to use in identifying the ideal of an interval. Although expressions such as Schwebungen are mostly related with beats, broader meanings are discussed. Hints of the use of alternative, not beat-related cues, are identified. A series of practical tuning experiments was performed in which selected intervals were tuned, the accuracy of the tuning process being assessed from recordings, which were subjected to spectral analysis. Only cues that could be related to historical sources were used. The effects of factors such as pitch, pitch region, instrument, interval type, and particularly the potential absence of relevant partials were investigated, statistical methods playing a substantial role in the research. A logbook was created, where the experimenter detailed the cues used for each tuned interval in one of the experiments. The recorded information provided some insight into a number of strategies a tuner may use for coping with difficulties in cases of absent or weak partials. The impact of inharmonicity on the exact size of just intervals was also examined, both on theoretical grounds and based on data from the experiments. A number of case studies were included, where a comparison was made between missing partial notes predicted from plucking points and the degree of absence of those partials in the actual spectra for some historical instruments.

My dissertation is an investigation of the rhythm and fills presets on the Mellotron MKII (1964) through a series of compositions. All the sounds used in these compositions are Mellotron sounds from the MKII, which were edited and arranged using a digital audio workstation (DAW). In this study I dissect the instrument, and outline every aspect of the rhythms and fills presets. In the process, I develop an expanded model of performance practice on the instrument, presenting new playing and compositional possibilities. These are made possible through comprehensively documented analysis of the instrument’s sample set and the tempo, key and pitch permutations achievable through its on-board modulation controls. The Mellotron is significant because it was among the first samplers in history, and quickly became an iconic sound, woven into the cultural fabric of 1960s British pop. The Mellotron was used on The Beatles’ ‘Strawberry Fields Forever’, Led Zeppelin’s ‘Kashmir’, David Bowie’s ‘Space Oddity’, and The Rolling Stones’ ‘2000 Light Years From Home’, to name a few. While the Mellotron is featured on these famous songs, it has never been used as a solo instrument for a long form composition, nor have its samples ever been transcribed. The study takes a reflexive approach, using journals compiled through the composition process to support the development of new Mellotron techniques and compositions. The compositions presented in this study establish and demonstrate the Mellotron’s capability for extended solo work. The new techniques presented here make the Mellotron more practical for improvisation, composition and performance in new musical contexts. Additionally, the research expands scholarly/educational literature on electromechanical keyboards, providing in-depth technical, historical and musical data on the Mellotron. / Art History, Visual Arts and Musicology / M.

As epidemiologic research demonstrates health concerns for hand problems among pianists, scientists are measuring historic piano keyboards and realizing that much of the piano literature was composed for and played on pianos with smaller keys compared to what is used on the modern piano. Having to play this literature on a larger keyboard is especially difficult for small-handed piano students and professionals. Fortunately, smaller keyboards are now available for use with standard pianos - and research shows that this ergonomic adjustment does reduce piano-related hand pain for small-handed musicians. Major universities are now offering this option to students, but only a few music schools possess these keyboards and not many people know about them. There are no known research studies to address people's awareness and attitude toward ergonomically scaled piano keyboards (ESPKs). The purpose of this study was to assess perception and attitude toward ESPKs and help to raise its awareness. To examine pianists' perception, two surveys was composed. First one was conducted on UNT campus in which ESPKs are available for their students, and the second survey was carried out on schools of music in the United States. The results reveal that substantial number of people already know about the existence of ESPKs, but they are not totally aware specific information about ESPKs. Subjects who are aware of ESPKs report significantly higher positive attitude compared to those have not known about ESPKs. Results from this study may have implications for health education initiatives within NASM schools of music.

Playing‐related pain is a common and serious problem among pianists. Information on cause and prevention is extremely limited due to a lack of scientific research. The purpose of this study was to (1) review and describe risk factors for piano‐related pain among college students and piano teachers that were reported in my previous two research studies, (2) justify the use of an ergonomically modified keyboard as a potential solution for reducing playing‐related pain, and (3) test and evaluate the effectiveness of an ergonomically modified keyboard for alleviating pianists' pain. Both study populations reported high prevalence rates for playing‐related pain: 86 % for college students (n = 35), 91 % for piano teachers (n = 47). For both populations, statistical analyses confirmed that pianists with small physical size (hand size) were more prone to pain. This finding helped rationalize the use of an ergonomically modified keyboard (the key width is 1/16 narrower than the standard) for small‐handed pianists as an ergonomic intervention. To test the effectiveness of an ergonomically modified keyboard, 35 college students played identical music on both the reduced-sized keyboard and the standard keyboard. Observations of video‐recorded performances revealed that small-handed pianists can avoid extreme stretching of their hands when playing on the modified keyboard. Statistical analysis of questionnaire data confirmed that the modified keyboard helped small‐handed pianists to play with less pain and tension. These results warrant the serious consideration of adopting ergonomic principals into the world of piano.

La musique française pour clavecin des XVIIe et XVIIIe siècles est-elle jouée de nos jours telle qu’elle devrait l’être ? De quelles sources disposent musicologues et musiciens pour approcher au plus près l’authentique sonorité du clavecin, la technique de son jeu, et la compréhension de son répertoire ? Cette approche nous a conduit à discerner neuf points déterminants, essentiels à la compréhension de la facture du clavecin. La mesure d’octave des claviers français de l’époque était inférieure à celle des instruments des pays voisins, et notamment inférieure à celle appliquée dans la facture de nos jours. Pour mémoire, cette mesure conditionne l’écartement entre le pouce et l’auriculaire, lequel écartement influence le jeu. Si l’écart est de moindre taille, les doigts sont plus rapprochés, et de ce fait, la main gagne en décontraction. Le jeu à la française se distingue aussi depuis ses origines par l’extrême souplesse de l’harmonisation, le peu de tension des cordes et le diapason bas (le La3 à 392 – 406 Hz). Par ailleurs, nous avons pu révéler l’existence de clavecins à trois claviers, la présence du seize pieds et du jeu nasal dans certains instruments (alsaciens notamment), et la paternité française de l’éclisse courbe en forme de « S ». Concernant les claviers, l’évolution de l’ambitus de l’instrument depuis le début du XVIIe jusqu’à la fin du XVIIIe siècle est bien connue des musicologues et des musiciens. Toutefois, aucune étude de cette évolution n’a été réalisée pour démontrer l’élargissement des claviers depuis le premier livre imprimé en 1670, les pièces de clavecin de Chambonnières, jusqu’à l’ambitus définitif des cinq octaves imposées dans les pièces de clavecin en concerts de Rameau en 1741. Notre étude s’est également étendue aux cordes, par la vérification de leur épaisseur et des matières dont elles étaient faites. Il s’avère que les facteurs de l’époque utilisaient des diamètres inférieurs à ceux des cordes actuelles, et qu’elles n’ont jamais été en cuivre dans les basses. Seul le laiton à forte teneur en cuivre était considéré comme satisfaisant pour la sonorité des cordes les plus graves. Quant aux cordes des trois cinquièmes supérieurs du clavier, elles étaient faites en fer mou qui n’avait qu’une faible tension. Il va sans dire que l’acier, employé de nos jours, était inconnu à cette époque. Enfin, il est admis aujourd’hui que le clavecin, une fois le tempérament posé, s’accorde en octaves pures, alors qu’il en était tout autrement au XVIIIe siècle, ainsi que nous l’avons établi à travers un texte de Corrette. / Is French harpsichord music of the 17th and 18th centuries played today as it should be ? What sources can help musicologists and musicians to reproduce the authentic harpsichord sound and playing techniques of that epoch, and understand its repertoire, as faithfully and fully as possible ? The mere fact that this music went unplayed for so long prompts that question. In fact, the harpsichord was forgotten overnight. The favoured instrument of court and fashionable society under the ancien régime, it had aristocratic associations which doomed it when the Revolution came. A century later, in June 1889, the noble, silvery sound of its plucked strings made a first, hesitant comeback, thanks to Louis Diémer. But it was only in the 20th century, between the two world wars, that Wanda Landowska’s tireless enthusiasm gave this baroque keyboard instrument a new lease of life. Interest in building “old-style” harpsichords, using traditional techniques, first developed in the late 1950s, and their popularity has grown steadily ever since. Today’s enthusiasts want to go back to the origins, and revive old ideas and techniques, but they still have a long way to go. At an earlier stage, techniques used in making pianos were extended to harpsichords - and some of these “alien” elements and additions are still present. We felt the time had come to clarify the picture by consulting certain contemporary texts, which had been unduly neglected. We found indeed that these were at odds with twentieth- century improvements, had been mistranslated or misunderstood, or were, quite simply, hard to find.Anyone wishing to form an idea of the original harpsichord sound must start with organology, and the various instruments used by French musicians in the 17th and 18th centuries offer valuable clues. X-ray examination reveals their design and shows how they were regulated (keys, jacks, plectra).Thanks to this approach, we have identified nine essential factors which illuminate the design and construction of these instruments. French manuals of the time had a narrower octave span than those of instruments made in neighbouring countries - or today. Span, of course, determines the distance between thumb and little finger, which itself affects playing. The smaller the gap, the closer the fingers, and the more relaxed the hand. From the beginning, the French sound was also distinguished by its highly flexible harmonies,low-tension strings and low pitch (A3 at 392-406 Hz.). We also found that some harpsichords had three manuals, that some (particularly Alsatian instruments) had 16 foot stops and a lute stop, and that the S-shaped bentside was a French innovation. Musicologists and musicians already know in general terms how manuals evolved from the early 17th to the late 18th century, but no specific research has been done on the process by which they became wider, between 1670, when the first book, Chambonnière’s Pièces de clavecin, was published, and 1741, when Rameau’s Pièces de clavecin en concerts made five octaves the norm.We have also studied strings, their thickness and the materials of which they were made. We have found that string diameter was smaller than it is now, and that bass strings were never made of copper. Only brass with high copper content was thought to give the deeper strings a satisfactory sound. Strings on the upper three-fifths of the manual were made of soft iron, which had little tension. Steel, which is used today, was obviously unknown.Finally, harpsichords, once their temperament is established, are today tuned in pure octaves –which, as a text by Corrette has shown us, was far from being the case in the 18th century.
