Sonata for Horn, Trumpet and Trombone movement 1
- Texture
- There is simple melody dominated homophony texture
- The trumpet has the tune, the trombone plays a simple bass line, and the horn providing harmony with alternating notes
- Sometimes the top two instruments join forces in two part texture, eg. Bar 12, where they are in 6ths
- Bar 25: Monophony, where the tune is shared between instruments
- Bar 26: three part texture where the trumpet and trombone move together in two part counterpoint, while the horn has wide ranging broken chords
- Bars 40-45: 'Oom-pah' accompaniment
- In the last bar all the instruments move in octaves, in homorhythm
- Structure
- Very loose ternary form containing several short themes.
- Section A: Bars 1-25/G major
- 1-8: Main theme modulating to D major
- 9-17/17-21: Faster subsidiary pair of themes
- 22: Return of opening idea but slower and with suggestions of tonic minor (gm)
- Section B: Bars 26-57
- 26: New slower theme in E flat, played by the trumpet
- 30: The horn then takes over
- 34: The trumpet resumes the theme
- 39: A four bar linking section includes two octave leaps for trumpet, followed by a miniature trumpet cadenza
- 40: A further theme, related to the opening melody of the movement, in B flat
- Section A (including 4 bar Coda): Bars 58-end
- Return of the main theme in the tonic key (G). Music from the end of Section B (Bar 48) is then interpolated
- 73: The subsidiary ideas return
- 86: A short chromatic coda, the piece begins to gradually slow
- Tonality
- Fundamentally tonal
- Frequent discords, which reduce strength of keys
- Frequent chromatic notes weaken sense of key
- Bar 86: scalic phrase in trombone
- Poulenc tends to modulate to remote keys instead of closely related ones
- The beginning is in G major
- The middle is in the unrelated key of E flat (Bar 26), though there are a number of chromatic notes, including the A and B naturals in the trombone (26-28)
- Bar 40: music in B flat
- Harmony
- Harmonies often quite bare
- Last bar in octaves with no chordal notes at all
- Bar 4: 'Simple' perfect cadences transformed by discord
- Harmony often outlines by broken chords. At the beginning of the middle section (Bar 26) there is a first inversion chord of E-flat, with the horn outlining the root and fifth of the chord
- Bars 86-7: trumpet plays B flat, sounding underneath the trombone's chromatic descent
- Melody
- Melodies are frequently simple diatonic tunes, e.g. main theme in G, Bars 1-4
- Tune often outlines broken chords, eg. first three notes of the trumpet music
- Occasional large leaps, eg. octave on Bar 2
- There are occasional ornamental phrases eg. the grace notes in Bar 12
- Conjunct music found e.g. trumpet Bar 4
- Sometimes extends to more scalic music e.g. Bar 9
- Rhythm and Metre
- Principal melody contains mainly quavers and semiquavers, with crotchets for the cadence
- Tunes often begin on the anacrusis (up-beat), eg. the first phrase
- Bar 39: semiquaver scale in free rhythm
- Bars 13-14: syncopation in upper two parts
- Times signatures change frequently
- Bar 39: 9/8 time signature, though this is a way of notating a bar of 4/4 plus a quaver anacrusis leading into next section of the movement
- There are three bars in quintuple time (bars 17, 65 and 81
- Speeds change frequently and are ofte used to differentiate between sections
