Louis Couperin (c. 1626-1661) was an outstanding member of the seventeenth-century clavecin school and an important link in the Couperin dynasty. His works for the harpsichord, or clavecin, have been neglected. This is due primarily to the fact that there are relatively few of his works, in comparison with those of his nephew, Franois Couperin Le Grand, who greatly overshadows him. Louis wrote no treatise on how his works are to be played, and there are few accounts of him, or his works, that are written in English. There is no biography of Louis Couperin. A more detailed study should be made of his music and its place in the French clavecin literature. Before examiinig the music itself, however, it is necessary to trace the origins and development of the clavecin school and its style.

The harpsichord concertos of Wilhelm Friedemann Bach (1710-1784) have suffered undeserved neglect. The four authenticated solo concertos remain in manuscript, with the result that his contribution to the history of the keyboard concerto has been largely overlooked. This study begins to correct this situation by examining these four concertos--F41 in D Major, F43 in E Minor, F44 in F Major, and F45 in A Minor--as well as the published two-harpsichord Concerto in E-Flat Major, F46, and the incomplete Concerto in E-Flat Major, F42 in order to assess W. F. Bach's contribution to the keyboard concerto following its origins in the early 1700s. The results of this investigation show that W. F. Bach took the early keyboard concerto of his father's generation and added many of the characteristics which became associated with the mid-eighteenth century concerto. Friedemann retained the polyphonic interplay between tutti and solo, harmonic language, and tonal plan of his father's compositions and added a wealth of rhythmic ideas and a more modern melodic style. He worked within an established four ritornello/three solo plan for the outer movements, but employed a variety of formal plans for the middle movements. Friedemann heightened the contrast between the solo and the orchestra and infused the solo part with formidable virtuosity. At the same time he ensured that the solo and tutti material was related so that the two forces would work together while maintaining distinct identities. This study shows the high merit of W. F. Bach's harpsichord concertos and adds to another chapter in the history of the pre-Classical keyboard concerto.

<p>This dissertation traces the range of popular forms and practices associated with the harpsichord in the twentieth century in the United States, focusing on the 1950s, 60s and 70s. It draws on archives of period correspondence, sound recordings, and news clippings, as well as on my interviews with harpsichord builders and performers and on fieldwork I conducted at a prominent American harpsichord company during 2008. I argue that the harpsichord enabled practices and discourses through which the white middle class could critique the post-World War II United States, and that the material aspects of the harpsichord--its sound, its wooden materials and its construction methods--provided a gauge by which to measure how far the postwar everyday had veered from what was imagined to be an "authentic" human existence.</p> <p>I focus the dissertation around the influence of a particular narrative associated with the harpsichord: that of the aristocratic, delicate instrument decimated by the Industrial Revolution. I first chart the ways that this narrative circulated in academic histories and popular media during the twentieth century, and how it was linked to perceptions of the harpsichord's physical "shortcomings." Focusing on its career in 1940s-60s popular music recordings, I then show how the stereotype of its "tragically disadvantaged" sound shaped acoustic and discursive constructions of that sound. I continue by demonstrating the classed critiques surrounding the instrument's commodification as a "do-it-yourself" kit--an affordable product that seemed to contradict the instrument's history as an elite, custom-made object. Lastly, I show how the harpsichord's story articulated with the biographies and sentiments of specific people, particularly those affiliated with the shop of Massachusetts harpsichord builder Frank Hubbard in late 1960s and early 1970s. Ultimately, I argue that the Movement's ideal of "historical authenticity," along with the post-World War II mass appeal of period instruments and period performance practice, emerged out of time and place-specific meanings, and through multiple social and commodity networks.</p> / Dissertation

Comparatively few theoretical studies exist on the keyboard sonatas of Domenico Scarlatti. His music remains largely unexplored. This study investigates formal and functional aspects of the "first halves" in the Venice XIII collection (K 514--K 543) and reveals links to the aesthetics and traditions of his contemporaries. It suggests and examines relationships to the development of the sonata genre. To accomplish this, the study proposes a theoretical base for critical analysis and presents a specialised terminology to examine the features of mid-eighteenth-century sonata forms. The arguments of Michelle Fillion, J. P. Larsen, and Wilhelm Fischer are central to the discussion. Studies by William Caplin, Barbara Foster, Klaus Heimes, Ralph Kirkpatrick, and James Unger also contribute to the development of the theoretical base. An analysis section views the selected repertoire and some contemporary works according to the criteria the thesis establishes. An epilogue sums up pertinent observations made in the analysis section.

Present-day builders of harpsichords disagree as to the use of iron or carbon-steel wire in their attempt to duplicate the tonal qualities of the early 16th century instruments. The variations in tone produced by vibrating iron and steel wires may be due, at least in part, to differences in their decay characteristics. A wire was set into vibration by placing a section in a magnetic field and passing a variable-frequency alternating current through it. A condition of resonance was established by appropriately selecting frequencies, lengths, and tensions that would simultaneously satisfy the relationship: fr = n/2L(T/p)1/2. Then measurements of decay time as a function of frequency were made for a variety of typical harpsichord strings: iron, steel, brass, bronze, etc. Samples varied in diameter from 170 mm to 600 mm and the resonant frequencies ranged from 20 Hz to 12,000 Hz. Changes in energy loss through the supports were measured by varying the size and mass of the supports and by modifying the method of attachment of the wire. Differences in loss of energy due to internal friction were noted in the comparison of decay times for different wire materials and diameters. The energy losses due to sound radiation and viscous damping were examined by placing the vibrating wire in a vacuum. Two significant conclusions, among others gathered from the data, indicate that: 1. For similar samples of iron and steel wire vibrating under like conditions, the steel wire will vibrate for a longer period of time than the iron wire. 2. Energy losses to sound radiation and viscous damping greatly exceed all other modes of energy loss from the wire. Suggestions for additional investigations based On the results of this paper are presented in the concluding pages.
