Comprehensive Study Notes on Mozart’s Operatic Complexity and Performance Practice

Visible vs. Hidden Complexity: Music contains obvious complexities alongside hidden ones that require careful observation to identify. These include elements of melody, harmony, and meter.
The Hearing of Key: There is a debate regarding whether modern listeners can still "hear" key. While individuals with perfect pitch can identify keys, their emotional or character associations with those keys vary significantly.
Subjectivity of Key Expression: Historically, composers and theorists had differing ideas about what specific keys expressed. For example, one person's perception of $C$ major might differ from another’s, though there was some general consensus during the Classical period.
Berner Muti’s Study (1931): In 1931, researcher Berner Muti analyzed all of Mozart’s vocal works—where text provides explicit evidence of character and emotion—to determine if Mozart maintain consistency in associating specific keys with certain affects. This study serves as a primary resource for understanding Mozart's personal key characteristics.

D Minor (The Death Key): In the Classical period, $D$ minor was regarded as the darkest key, often associated with death and terror. * Don Giovanni: This key is used famously in Don Giovanni during the scene where the protagonist, a manipulative womanizer, is dragged to hell. * Plot Context: Don Giovanni kills the father of a woman he pursued. Later, a statue of the father comes to life and pulls the protagonist into the underworld. * Biographical Connection: Scholars often associate the dark themes of this opera with the death of Mozart’s own father around the time of composition.
C Major and the "Sigh" Affect: While $C$ major is typically viewed as "bright," it can be used to convey profound sadness when paired with specific figures, such as "sigh" motives (appoggiaturas).

Clive Brown: The lecturer recommends Clive Brown’s book, Classical and Romantic Performing Practice, 1715 to 1900, as the definitive text on the subject.
The Research-Performance Gap: There is often a disconnect between musicologists and performers. Performers are still "catching up" to scholarly insights published decades ago.
Manuscripts vs. First Editions: * Authentic Mozart manuscripts are often messy and contain scribbles or corrections. * Legible, clean scores are more likely to be first editions or later copies rather than original manuscripts. * Mozart’s original manuscripts can be accessed for free via the Library of Congress in Washington, D.C.

The Pamina and Papageno Duet: * Character Subversion: The duet features Pamina (a princess/noble soprano) and Papageno (a comedic/buffo bird-catcher). Usually, noble characters pair with nobles, and comic characters pair with other comic characters. * Metric Displacement: To highlight the "wrongness" of these two characters singing a love duet, Mozart manipulates the meter. * Notation Details: Mozart wrote the duet in $\frac{6}{8}$ , but it is often compared to $\frac{3}{8}$ where the emphasis is shifted to displace the weight of the downbeat. Most modern recordings fail to reflect this intentional metric discomfort.
Libretto and Singspiel: * Schickeneeder: The text was written by Emanuel Schikaneder (referred to as "Schickeneeder" in transcript), who also played Papageno. * Format: The opera is a Singspiel, meaning it features spoken German dialogue rather than sung recitative, making it accessible to the common people rather than just the educated elite. * Textual Irregularities: The libretto is described as "wonky," with imperfect rhymes and syllables that do not always align with standard poetic structures, which Mozart utilized for characterization.

Conventional Phrase Lengths: The majority of Classical period pieces utilize even-numbered phrase structures: $\text{2-2-4}$ , $\text{4-4-8}$ , or $\text{2-2-6}$ .
Mozart’s Use of Odd Numbers: Mozart introduced odd-numbered phrases (e.g., $3$ or $5$ bars) to create a sense of unease or interruption.
Grand Partita (Serenade No. 10): * Scored for $12$ winds and a double bass (referred to as "12 million 8 days" in transcript error, contextually 12 winds). * Allegro Analysis: The movement opens with a $5$ -bar phrase, followed by regular $2$ -bar phrases. Later, a $3$ -bar piano phrase is suddenly interrupted by a massive forte ensemble entry. * Contrast: Mozart utilizes simultaneous contrasting articulations, such as long legato lines occurring over staccato strokes.

Note Length and Value: According to C.P.E. Bach and Leopold Mozart, notes without specific articulations should typically be played at half their written value.
Energy in Silence: Historical performance practice emphasizes how a note is released. Releasing a note properly maintains musical energy through the following silence, whereas modern performers often let the note "lay there."
Vibrato and Affect: The use or absence of vibrato significantly changes the "affect" (emotional atmosphere) of a piece.
Cosi Fan Tutte Analysis: * The second version discussed (Theodore Cerensis and Musica Aeterna) features a fortepiano performing improvised ornamentation and introductions between numbers. * Tempo and Sincerity: A faster tempo can make a piece feel less melancholy and less sincere, whereas a slower tempo allows for more "musicality" but risks becoming stagnant. * The "Sigh" Effect: Breathlessness in vocal performance (literal audible breaths) can enhance the "sighing" affect in Mozart's music.

Trills: * Main Note vs. Appoggiatura Trills: In a melodic scale line, trills should often start on the main note to maintain the integrity of the scale. Starting on the upper note can obscure the melodic direction. * Cadential Trills: These differ from melodic trills and typically follow different rules for starting notes.
Rubato in the Classical Period: * As described by Mozart in letters to his father, the left hand (accompaniment) should remain in strict tempo. * The right hand (melody) is free to weave in and out of the beat. * If the performer is slow at the start of a bar, they must be faster at the end to ensure they arrive at the next downbeat on time.

Q: Does anyone have an idea about complexity?
A (Joey): Within the theory of it, potentially the harmonies and stuff?
Q: Do you guys hear key? Does anybody hear key when you hear a piece of music?
A (Student): Those of us with perfect pitch can. Sometimes.
Q: Do you associate different keys with different feelings or emotions?
A (Student): No. (Another student): Sometimes. For example, $C$ maybe is pretty bright.
Student Question on Score Marking: Could you just mark the thoughts or mark the score?
Response: I suppose, but the conductor might not think of it until the day of performance. The process is a two-way street between the conductor's inspiration and the musicians' execution.
Student Question on Exam Prep: Do people feel like they're being cheated if they only know one through?
Response: We will do Mozart on Monday and then move to the Romantics. We've been doing exam review as we go, so we won't need a massive dedicated block for it later.
