Piano featured lots.Form: Chamber music along with symphony, sonata and concerto gained popularity. Sonata form developed.Features: Alberti Bass – repeated figure in LH – broken chord

9 1st Movement Analysis Piano Exposition bars 67-156 Bars Theme 1aA Major (Piano with string acc.)Repeated version decorated hugelyTheme 1b bars 83-98(piano)Broken chord acc in pianoScales and sequences in RHLinks 1st and 2nd Theme – links to E Major

11 1st Movement Analysis Piano Exposition bars 67-148 Bars – Theme 2aa (1d)Piano plays wildly elaboratelyBars 137 – material from 1b acts as codetta still in E majorTheme 3a (1e) bars violinSounds like new section but appears later in recap so really belongs to the exposition. Describe it as a ‘development theme’.
12 1st Movement Analysis Development b156-170 Bars – Theme 3 (1e) Part OneExpecting keys of A Major-E Major – D Major – 3 related minors F# minor – C# minor – B minorHowever Mozart does not do thisKey sequence uses falling 3rds E-C and C-ABars 156 – 4 bar phrase in E minorDialogue between clarinets, bassoons and hornsBar 160Repeated above idea in C MajorBar 164Repeat but extend now in A minorPiano continues with idea ending in F MajorStrings take idea into D minor
13 1st Movement Analysis Development b170-198 Bars 170 – Theme 3 (1e) Part TwoC material developed againCl and fl play in canon at a 4thRH plays scales and semi-quaver passagesBars 177F major chord begins preparation to bring piece back to dominant E which brings music back to A for recap.B repeated E’s on low strings and hornsRH plays scales and broken chordsB197 rising chromatic scale
14 1st Movement Analysis Recapitulation b198-314 Fusion of orchestral and piano exposition.Material is shared between soloist and orchestraOld themes returned but with renewed freshness due to 1E being used in development.
15 1st Movement Analysis Recapitulation b198-314 B198 – 1A as usual except with strings and flute.B213 – 1B as b82 with piano joining in. All in A major.B229 – 1C now in original key (compare b99)B244 – 1D compare with b114B261 – Decorated piano passage with Cadenza in sight 1E is re-introduced1E played 3 times:SoloistClarinet and Bassoon4 part counterpoint with piano decoration
16 1st Movement Analysis Recapitulation b198-314 Theme 1E is original simplicity not like its appearance in exposition two.Alberti bass b272 – ends on trill at b283B284 – Orchestra play 1B only 6 bars ends with 2 beats rest.B290 – 1E arrives again stating its importance – very exuberant playing of the theme.B297 – Cadenza begins – soloist usually improves but Mozart wrote it out…taking no chances for the movement to become disjointed.B298 Coda – material from 1D used to close coda.
