The Viola Sonatas / "F.A.E." Sonata

Austro-German modernism is a current in early 20th‑century classical music centered in Vienna, Berlin, and other cultural hubs of the German‑speaking world. It is marked by the break with late‑Romantic tonality through chromatic saturation, atonality, and ultimately systematic twelve‑tone/serial procedures; a heightened, often expressionist intensity of gesture; concentrated motivic work; and refined attention to timbre (including Klangfarbenmelodie). While many composers retained or reimagined traditional forms, their harmonic language, rhythm, and orchestration pursued a radical new expressivity. Beyond its signature pitch techniques, the movement embraced new vocal practices (such as Sprechstimme), chamber ensembles of novel makeup, and an aesthetics that oscillated between ecstatic subjectivity and ascetic concentration. Its innovations set the groundwork for much of 20th‑ and 21st‑century concert music.

Impressionism in music is a late-19th- and early-20th-century style that prioritizes color, atmosphere, and suggestion over overt drama and functional harmonic progressions. Originating in France, it parallels the visual arts movement in its fascination with light, timbre, and fleeting impressions. Musically, the style favors modal, pentatonic, and whole‑tone materials; parallel (planed) chords; unresolved dissonances; and ambiguous tonal centers. Rhythms are flexible and often blur a sense of strong meter, while textures shimmer through delicate orchestration, pedal tones, and arpeggiated figures. Rather than strict sonata designs, impressionist works tend to be episodic, evocative, and programmatic, conjuring landscapes, water, night, and dreamlike states.

A character piece (German: Charakterstück) is a short, single-movement work—most often for solo piano—designed to evoke a specific mood, scene, or persona. Typically lasting one to five minutes, it prioritizes vivid expression and atmosphere over large-scale form. Titles are often descriptive (e.g., Nocturne, Impromptu, Romance, Intermezzo, Barcarolle), guiding the listener’s imagination. Musically, character pieces favor singable melodies, rich but economical harmony, clear textures, and flexible tempo (rubato). Common plans include ternary (ABA) or through-composed designs, with coloristic pedaling and nuanced dynamic shaping to paint the intended character. While the piano repertory dominates, the aesthetic extends to other instruments and small ensembles, and it remains central in pedagogy and concert encores.
