Topics: Paul Celan, Imre Kertész, the Holocaust, Bach's funeral music Key concepts: fugal purpose, character, and essence. It is the fugue's essence to reveal the likeness of seemingly unlike things. This alternate study of the gm fugue, asks why Paul Celan titled his poem on the Holocaust a "fugue" (Todesfuge). It compares Celan's work with the axial fugue of BWV 106, which uses the same subject as the gm fugue of WTC Book I. An analogue is suggested of the Jewish- Christian experience, with lessons of the fugue and Holocaust applied to contemporary life. Features the paintings and poetry of Holocaust suvivor, Tamara Deuel.

Topics: Nietzsche, Wagner, philosophy, nihilism, St. Matthew Passion Key concepts: Mendelssohn's revival of the St. Matthew Passion stimulates interest in Bach's music; Schumann and the Bach Gesellschaft; 19th century reception of Bach as "healing force"; compared with Wagner; Nietzsche's nihilism, friendship with Wagner, and 1878 criticism of Bach in Aphorism 149, Human, All-Too-Human. Questionnaire: Students can be directed to answer ten questions online and email their answers to the instructor. Topics: Scheibe, Mattheson, rhetoric, word painting Key concepts: Scheibe's criticism of Bach's music and Mattheson's challenge; Bach responds by demonstrating mastery of musical rhetorical techniques: gradation, paronomasia, peroration, tmesis, and antithesis; implications of canzona rhythm, suspiratio, and chiastic motives as word paintings; discussion of rhetorical "meaning"; fugue compared with BWV 4. Topics: wave theory, quantum mechanics Key concept: fugue is like a wave Fugue has three subjects plus a countersubject; counterexposition treats subject and countersubject separately, in stretto; perceptual challenge of this type of fugue to maintain distinction between motives; fugue likened to waves of all kinds: ocean, sound, light, electromagnetic; review of quantum physics from Niels Bohr and Werner Heisenberg; Bohr contra Einstin debates; contemporary revolution in physics; Carver Mead's Collective Electrodynamics; fugue as intelligent design; the "Uncreated Wave" Topics: time, tempo, perception of time, definition of time Key concepts: Fugal time is neither circular nor linear, but epochal and spiraled. Meaning in the fugue is dependent upon relationships between the past, present, and future. The intensity of conscious cognitive processing required in listening to a fugue protracts (and compresses) the passage of time: the fugal future is in its past, and its past is in its future. Topics: Lutheranism, chiasmus, lamento, triple fugue, Bach symbols, melodic inversion, passion music Key concepts: definitive triple fugue of the cycle; two of its subjects borrowed from earlier works in the WTC; each subject receives its own exposition, followed by development with subjects prior to it; third of three "passion fugues" contains many symbols, both of the composer and his faith. Topics: absolute expressionism, modern art, Kandinsky, Schoenberg Key concepts: Kandinsky's 1914 painting, Fuga, provides occasion to explore the aesthetic ideal of expressionism and the historical roots of modern art, both in reaction to impressionism and as a continuation of the western aesthetic. Bach's legacy to Schoenberg and Kandinsky can be found in the principle of affect coupled with motivic development and economy of means. The spiritual quest of each artist also finds "expression" in his unique style and medium. Topics: Grand Canyon, geology, double counterpoint Key concepts: The fugue's subject and countersubject are heard in its various "voices." This analysis is primarily concerned with how the composer notates fugal voices so that they can be aurally and visually distinguished from each other. Analogy is made to the sedimentary layers of Grand Canyon, Arizona, with many allusions to its geology and history. This particular fugue is famous for its double counterpoint at the octave, 10th, and 12th--structures that are illustrated and explained. Questionnaire: Students can be directed to answer ten questions online and email their answers to the instructor. Topics: Bach's Bible, Calov, Frederick the Great, Musical Offering, Enlightenment Key concept: Bach's commitment to the preaching purpose of music. The narrative begins with Bach in the Weimar jail, by some counts beginning his composition of the Well-Tempered Clavier, and ends with his 1747 encounter with Frederick the Great. The discussion is threaded with references to Bach's many underlinings and annotations in the Calov Bible. His Lutheran understanding of music's purpose is contrasted with the galant style preferred by Frederick, as well as the philosophical assumptions of Aufklärung and what would come to be known as the Enlightenment. Topics: Architecture, Christopher Alexander, Milton Babbitt Key concepts: Art = beauty, beauty = life, life = relationships. This aesthetic philosophy, articulated by Berkeley professor of architecture in The Nature of Order, is applied to the fugue and contrasted with Milton Babbitt's article, "Who Cares if You Listen?" Topics: Humor in music, self-similar structures, matryoshka doll Key concepts: Dr. Ledbetter offers three reasons why this fugue should be interpreted as parody. Nevertheless, there are some serious ideas here, mainly in the self-similar contours and rhythms of the subject's head and tail. The fugue likened to a Russian "babushka" doll. Topics: Invariance, Permutation, Syllogism, Plato and Meno's Square Key concepts: The brilliance of Bach's fugues lies in his understanding of process and invention. Unlike "book fugues" that mimic form, Bach understood that the fugal complex must have the capacity to generate new material from old. In this fugue Bach interrupted a process of permutation. The analysis asks why, concluding with analogies from astronomy, philosophy, and the words of C. S. Lewis Topics: Schweitzer, Sartre, Nietzsche Key concepts: This fugue, the most logocentric of the cycle, provides an opportunity to compare theistic and atheistic existentialism, as exemplified in the writings of Bach biographer/editor/performer, Albert Schweitzer, and his cousin, Jean-Paul Sartre. Thematically, the analysis focuses on the Stoic concept of logos and its etymological derivatives. The logos of Bach's counterpoint demands recognition as purposeful and meaningful, not merely a display of contrapuntal process. Questionnaire: Students can be directed to answer ten questions online and email their answers to the instructor. Topics: Triads, Tonality, Trinitarianism Key concepts: Bach's music is the way it is because other things are the way they are. The power of Bach's music is proportional to the power of those other things. This fugue gives opportunity to consider how Trinitarian dogma has shaped musical structure. There is a brief discussion of the changing attitudes toward musical meaning and purpose during Bach's lifetime. This is contextualized in the dispute between Buttstett (representing the cantoral tradition) and Mattheson (representing the Enlightenment view). Topics: Dance, Relationship of the bm fugues Key concepts: This fugue is a dance, a passepied. The analysis considers Bach's use of the passepied in BWV 22, BWV 49, and BWV 202, the "Wedding" Cantata, and concludes that, in his liturgical music, Bach associated the passepied with the Wedding Supper of the Lamb. Associations between the bm fugues of Books 1 & 2 are developed with the conclusion that the former represents the cross and the latter the crown. The pair are theorized to be Bach's musical expression of Hebrews 12:2 -- "Who for the joy set before him" [Bk 2] "endured the cross" [Bk 1]. The last 14 measures contain the WTC's only instance of Bach's cross and crown motives (descending and ascending chromatics) in simultaneity. This follows Bach's 2nd quotation of the gefangen ("captured") motive from the St. Matthew Passion: counterpoint that he had earlier quoted in the bm prelude and fugue of Book 1.
