Musical Terms (7)

• Allegro vivace Italian
  Fast and lively — more animated than Allegro alone. Implies a light, buoyant character in addition to speed.
  In Clementi's sonata finales, Allegro vivace should feel playful and effortless. Keep the texture transparent and the touch light; avoid heaviness in fast passages.
• con disperazione Italian
  With desperation; one of Clementi's most vivid expression marks, appearing in the Didone abbandonata sonata.
  This marking demands genuine urgency and abandon — a sense that control is slipping. Push tempos to the edge of clarity and allow dynamic extremes. It is among the most emotionally extreme directions in all Classical piano music.
• con espressione Italian
  With expression. A direction asking the performer to bring out the emotional content of the passage.
  In Clementi's slow movements this often means projecting the cantabile melody clearly above the accompaniment, with subtle dynamic shaping within each phrase.
• Largo patetico e sostenuto Italian
  Slow, pathetic (in the Classical sense of deeply felt), and sustained. A compound direction combining tempo, character, and touch.
  Sustain every note to its full value; avoid any gap between melody tones. The patetico quality calls for a heavy, expressive tone — not thin or delicate. Let the harmonic tension accumulate slowly.
• legatissimo Italian
  As legato as possible; the most connected and smooth touch, with each note overlapping very slightly with the next.
  Clementi was a pioneer of the legato school of piano playing, in contrast to the more detached style of Mozart. Legatissimo in his slow movements calls for the finger to remain on the key until the last possible moment before moving.
• patetico Italian
  Pathetic — in the 18th-century sense of deeply moving, stirring strong emotion. Not pejorative.
  Clementi uses patetico to signal his most emotionally intense writing. Lean into expressive rubato, dynamic contrasts, and singing tone rather than Classical restraint.
• velocità Italian
  Velocity, speed. Clementi frequently marks rapid passages to emphasise technical fluency as a goal in itself.
  In the Gradus studies, passages marked for velocity should be practised hands separately at a slow tempo before being combined. Even in performance, clarity of articulation matters as much as speed.
