Mozart Clarinet Concerto - Timbre and Texture
Question | Answer |
---|---|
Timbre - Sonority | This concerto is scored for a reduced classical orchestra, including 2 flutes, 2 bassoons, 2 horns in A, solo clarinet, 1st violins, 2nd violins, violas and cellos and double basses. |
Transposing instruments - Sonority (timbre/instrumentation) | The horns and clarinet are 'in A'. Meaning written pitch=C sounding pitch = A. So, the horns and clarinet sound a minor 3rd lower. They have a different key signature. The horns and clarinet have a key signature of C major, but tonality is A major). |
Role of the woodwind instruments - Sonority (timbre/instrumentation) | The clarinet is the soloist & plays the melody. Mozart writes difficult clarinet melodies. Mozart uses all three registers - low/chalumeau, middle/clarino and high/altissimo. Flutes play play or double the melody. The bassoons fill out the harmonies. |
Role of the brass instruments - Sonority (timbre/instrumentation) | The horns fill out the harmonies. The horns sometimes play pedal notes. The horn is limited to the notes of the harmonic series. And can't play melodies easily. |
Role of the string instruments (1st Violins)- Sonority (timbre/instrumentation) | 1st violins play melody, when the soloist isn't. Or, provide harmonic support and accompaniment. The 1st violins sometimes play in thirds with the clarinet or 2nd violins. |
Role of the string instruments - Sonority (timbre/instrumentation) | The violas provide harmonic support and mainly play the accompaniment. The cellos and double basses provide harmonic support. The cellos and double basses sometimes play pedal notes. |
Role of the string instruments (2nd Violins) - Sonority (timbre/instrumentation) | The 2nd violins provide harmonic support and mainly play the accompaniment. The 2nd violins sometimes play the melody instead of the 1st violins. |
Texture as a whole | On the whole, the texture is melody and accompaniment. There are alternations between lighter/reduced texture and tutti orchestrations. |
Section A - Texture | The texture is melody and accompaniment. Mozart occasionally uses parallel 3rds (e.g. between 1st and 2nd violins). |
Section B - Texture | Overall, the texture is melody and accompaniment.The texture at the start of Section B is much lighter than end of previous section. Mozart creates textural variety with some subtle use of polyphony. E.g. the clarinet melody is imitated in the violins. |
Section C - Texture | *The texture is melody and accompaniment. This section features antiphony between (low register) clarinet and strings. |
Coda - Texture | The texture is melody and accompaniment. Mozart occasionally uses parallel 3rds (e.g. between clarinet and 1st violins). |
