• Affekt German
  Affect or emotion. In Baroque theory each piece or movement was intended to express a single unified emotional state throughout.
  Identify the prevailing Affekt of each Pachelbel piece — the F minor Chaconne is tragic, the G major Chaconne is confident — and maintain that character consistently rather than introducing contrasting moods.
• Aria con variazioni Italian
  An aria with variations. The structural basis of the Hexachordum Apollinis — a simple, songlike theme followed by a series of increasingly elaborate variations.
  In Pachelbel's arias, establish the theme clearly and simply before the variations begin. Each variation should feel like a new perspective on the same material — vary touch, articulation, and dynamic level across the set.
• basso ostinato Italian
  A repeated bass pattern over which varied material appears in the upper voices. A defining device in Baroque keyboard music, used in chaconnes and passacaglias.
  In Pachelbel's chaconnes, keep the bass line steady and consistent regardless of what happens above it. The listener should always be aware of the repeating foundation — it provides the structural anchor.
• cantus firmus Latin
  A pre-existing melody — typically a plainchant or Lutheran chorale — presented in long, sustained notes while other voices move in counterpoint around it. The structural foundation of Pachelbel's chorale preludes.
  When playing a cantus firmus setting, the chorale melody must be audible and unhurried above the surrounding counterpoint. On the organ, draw a solo stop (Principal 8' or Flute 8') for the cantus firmus voice and a softer combination for the accompanying voices. The congregation must recognise the hymn tune — it should float clearly, not be buried in the texture.
• imitative counterpoint English
  A contrapuntal technique in which each voice successively enters with the same or similar melodic idea before combining freely. Pachelbel's characteristic method of composing the accompanying voices in chorale preludes, deriving their motives from the opening of the chorale melody.
  In Pachelbel's chorale preludes, the imitative entries before the cantus firmus enters are fore-imitations — each voice anticipates the chorale tune in shorter note values. These entries should be shaped as melodic lines in their own right, not merely preparatory filler. Bring out each entry clearly so the listener hears the gradual accumulation before the full chorale arrives.
• inégal French
  Unequal. A French Baroque performance convention in which pairs of equal written notes are performed slightly unequally — the first note lengthened and the second shortened — giving a gentle lilt.
  Appropriate for Pachelbel's suite movements in French style (allemandes, courantes). The degree of inequality should be subtle — think of a natural vocal inflection rather than a strong dotted rhythm.
• Magnificat tone English
  One of the eight Gregorian psalm tones to which the Magnificat canticle was chanted at Vespers. Pachelbel's 95 Magnificat fugues provided keyboard versets for each tone, to be played alternately with the choir in a liturgical exchange.
  Magnificat fugue versets are short — typically under two minutes — and must fit seamlessly into the liturgical flow. The tempo should be steady and the fugue subject clearly articulated from the first entry. On the organ, a modest registration (Principal chorus without reeds) suits the devotional character. The piece ends with the choir's next verse, so the final cadence should arrive with quiet finality rather than any flourish.
• non-legato Italian/English
  Not legato; a slightly separated touch that leaves a small space between notes without a full staccato separation. The default articulation in Baroque keyboard style.
  Pachelbel's keyboard music assumes a non-legato default. Avoid smooth, Romantic legato in most passages — a slightly lifted touch between notes gives the music its characteristic clarity and rhythmic profile.
• ornaments English
  Decorative notes added to a melody — trills, mordents, turns, appoggiaturas. In Baroque keyboard music ornaments are semi-obligatory, indicated by signs above the notes.
  Pachelbel's ornament signs follow German Baroque conventions. Trills generally begin on the upper auxiliary note on the beat. In slow movements ornaments add expressive weight; in fast movements they articulate rhythmic points.
• Pachelbel's chorale prelude model English
  Pachelbel's distinctive approach to the chorale prelude: fore-imitation in all voices before the chorale enters in the top voice in long notes, creating a layered texture that became the template for an entire generation of composers including Bach.
  Understanding the model helps performance: the fore-imitation entries (before the chorale appears) are compositionally derived from the chorale's opening phrase. Listening for this motivic connection enriches the interpretation. The entry of the cantus firmus is the structural event each fore-imitation section has been preparing — give it physical space by taking a slight breath (or space) before the chorale melody begins.
• south-German toccata English
  The keyboard toccata tradition of southern Germany and Austria, descending from Froberger, characterised by alternation between free improvisatory sections (with running passagework) and strict fugal sections. Pachelbel's organ toccatas follow this model directly.
  In a south-German toccata, the free sections should feel genuinely improvisatory — slightly flexible in rhythm, exploratory in character — while the fugal sections should be rhythmically precise and contrapuntally clear. The contrast between freedom and discipline is the essence of the form. Registration can change between sections: fuller for the fugues, lighter for the free passages.
• stop registration English
  The selection and combination of organ stops (ranks of pipes) to produce a desired timbre for a particular movement or section. In Pachelbel's relatively straightforward organ writing, registration choices clarify the texture rather than creating programmatic colour.
  For Pachelbel's chorale preludes, a Principal 8' or Gedackt 8' for the cantus firmus voice with a softer Flute 8' or Quintaton in the accompanying voices is historically appropriate and texturally clear. For the free organ works (toccatas, chaconnes), a full Plenum (Principal chorus) suits the fugal sections; for transitional passages, the Plenum can be reduced to Principals alone without Mixtures.
• terrace dynamics English
  A Baroque approach to dynamics in which volume changes in distinct steps (forte to piano) rather than gradually. Associated with the lack of a sustain pedal on harpsichord.
  On piano, use pedal sparingly and rely on finger touch for dynamic variation. Terraced dynamic shifts — particularly between repeated sections — are stylistically idiomatic and more authentic than gradual crescendos.
• verset French/English
  A short organ piece played in alternation with a choir, replacing or commenting on a verse of a liturgical text. Pachelbel's Magnificat fugues are the most systematic set of versets in the German Baroque repertoire.
  A verset must feel complete within its short duration — a clear beginning, a middle with contrapuntal development, and a conclusive cadence. Because it will be followed immediately by the choir, the ending should be clean and decisive. Avoid elaboration for its own sake; the brevity is part of the form's discipline.
