Unit Summary
Pupils analyse exemplar compositions to explore advanced compositional techniques including rhythm, texture, timbre and interaction between parts. They develop understanding of how composers create interest, contrast and clarity within ensemble writing.
Lesson Summary
You will learn to analyse how a piano trio uses complex textures to develop ideas and create variety, and you can incorporate some of those into your own composition.
Key Notes
- Considering the interaction between parts is an important part of composing.
- In the Romantic piano trio, the composer shared both the melody and accompaniment between the three instruments.
- They also used polyphony, antiphony, imitation, doubling and harmonisation to create a varied composition.
- Every style has idiomatic techniques for creating interaction between parts.
Vocabulary To Learn
- polyphony: a texture involving more than one equally important melodic line
- imitation: when a short part of a melody is copied (or 'imitated') in another part
- antiphony: where two or more instruments or groups have dialogue (similar to call and response)
- doubling: where a second part plays a melody in unison with another part
- harmonisation: where a second part plays the main melody with different notes, creating harmony
Common Mistakes To Avoid
- In a piano trio, the piano plays the accompanying chords, the cello plays the bass line and violin plays the melody.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Considering the interaction between parts is an important part of composing. In the Romantic piano trio, the composer shared both the melody and accompaniment between the three instruments.
2. What does this key word mean in this lesson? 'polyphony'
a texture involving more than one equally important melodic line.
3. Correct this common mistake.
Mistake: In a piano trio, the piano plays the accompanying chords, the cello plays the bass line and violin plays the melody. Correction: The three instruments serve varied roles in a piano trio. Many composers share the melody and the accompaniment between all three, and have them interact in different ways. It is a versatile ensemble, with lots of potential for interesting textures.
