Mozart's Piano Sonata, like the Sweelink is mostly scalic and stepwise but also uses arpeggios. Periodic 8 bar phrases are used like the one starting at the upbeat to bar 15-bar 23 at the imperfect cadence. Motifs are also developed in this piece as well, for example the first motif of the piece at bar 1 is varied at the beginning of the development section at bar 64 (with an upbeat), by it being in a different key and the last three notes are an ascending scalic pattern instead of a leaping pattern. There are many places in the piece where the melody is repeated, this is mostly seen in the recapitulation (bar 94) where the start of the piece is repeated, however it in this section the first section doesn’t modulate to the dominant and stays on the tonic which varies the melody slightly. The shape of the melody is very varied and covers a wide range for example intervallic expansion is shown in bar 20, followed by descending scalic patterns in bars 21-22, and across the three bars there is use of three octaves.
The Piano Sonata has a fairly rhythmically active using mostly quavers or semiquavers at a moderate tempo. There is a clear metre which is supported by clear cadences such as the one at bar 63. Also, regular harmonic rhythm is shown throughout the piece with chords changing twice per bar.
Harold in Italy is the most recent of the three pieces, and is also the longest showing more range in melody. Forexample there are two hemes and an Idee Fixe which are all used regularly through the piece. Theme A is bar 4, and is a rhythmical idea which is seen again in the Viola in the second half of bar 177. Theme B is a solo on the Cor Anglais from the upbeat to bar 35-38, this theme is very disjunct using leaps of 3rds and 5ths, and is separated into three motifs which are scattered around the whole piece for example at the upbeat to bar 86 on the flute the melody is based on theme B but it develops becoming more complex. The Idee Fixe starts at bar 65 and represents Harold as a main theme. The Idee Fixe returns a lot during the piece for example in the flute at bar 152, this is in the coda where all of the theme are brought together creating thematic unity. In the coda all three themes are played at the same time for example at bar 180 the Flute is playing the Idee Fixe whilst the Viola solo is playing theme B and the Violas are replicating theme A.
Compared the the previous two pieces this piece is slow rhythmically using much longer and sustained notes, however there is a clear metre. The tempo of the piece changes which is also different to the other two pieces, it slows down in the second section (bar 32) to half the speed of the first section.In this section the Idee Fixe is played in the Viola first at bar 65, when it enters it seems a lot slower than the rest of the orchestra. At bar 49, the orchestra becomes more rhythmically active with many parts having rhythmically independent parts. In bar 37 the Cor Anglias has syncopation but there is a strong pulse in the accompaniment keeping the beat. At the coda (bar 166) there is use of cross rhythms between the violas and the rest of the orchestra, this is because the Violas are playing double speed in 6/8 time, which is the same tempo as the first section, whereas the rest of the orchestra are playing at the speed of which the section section was being played.
