Corelli- Tonality and Structure

Binary form. (A,B, both repeated)

A Section

D major- Tonic. 2 bar opening phrase then answered

Modulates to A- Dominant (Bar 9, hinted at bar 4)

B Section

Modulates through variety of keys, Circle 0f fifths:

Starts in A (V); D (I, bar 22); Bm (i, 26); Em (iv, 28); G (IV, 30), Em (31); A (32); D (33); G (34); D (36)

1 of 40

Corelli- Instrumentation

Although a 'Trio Sonata' requires 4 performers:

Violin 1- 2 octaves and a semitone

Violin 2- 14th

Violone- Range of 2 octaves (same as modern cello)

Organ- Single manual pipe organ, no pedals. Plays continuo part

Frequent imitation, parts cross, ideas exchanged.

Violin 1 states material first, Violin 2 finishes whole sonata on top

Idiomatic writing, not too compex.

2 of 40

Corelli- Texture

Typically contrapuntal. 3 part texture.

Opening section: fugal violin 1 states subject (monophony) violin 2 answers a 4th lower

Bar 5: Violins start an inverted version of the subject in parallel 3rds. Violone completes original subject (middle of bar 6)

Homophonic at cadence points

3 of 40

Corelli- Harmony

Entirely functional and diatonic. Accidentals from related keys.

Mostly root and 1st inversion chords.

Dissonance through prepared suspensions and double suspensions. Usually resolve downwards by a step.

First beat of bar 39: violin 1 leaves dissonance unresolved with an upwards leap.

Frequent perfect cadences define phrase structure (bars 4, 10-11, 18-19)

Cycle of fifths and tonic pedal notes at ends of sections shows strongly functional harmony

4 of 40

Corelli- Melody

Monothematic. 

Melodic intervention derived from opening 3 note motif, based on a rising 3rd.

Developed by:

  • Rising sequence with added passing notes (bar 1)
  • Further sequence of embellsihed version (bar 2)
  • Inverted (bar 5)
  • Falling 1 bar sequence in violone (bar 15-17)
  • Anacrusis added for entries from bar 32

Octave leaps occasionally break characteristic descending sequences.

Corelli-Rhythm and Metre

Movement written in a gigue format (lively dance in compound time)

1st Violin syncopation (bars 26-27)

Hemiolas (bars 27 and 31) harmony changing on 1st, 3rd and 5th quavers of bar. 3/4 time feeling.

Quaver and semiquaver rhythms prevalant throughout. Occasional rhythms of longer duration occur in upper parts (e.g. bar 15)

33 of 40

Rag- Tonality and Harmony

Harmony only occurs in 2 respects: Double stopping of sarangi and drone of tampura interacts with melody.
