Final answer:
Examples of thematic development in music include syncopating the rhythm, altering the harmony, and changing the melodic outline of the theme. The correct answer is option a., b. and c.
Step-by-step explanation:
Thematic development refers to the various techniques used to develop and explore the central themes in a piece of music. In the given options, examples of thematic development are:
- Syncopating the rhythm of the theme: This means altering the rhythm of the main theme, creating a sense of tension and adding interest.
- Altering the harmony underneath the theme: This involves changing the chords or harmonies that accompany the main theme, altering the emotional impact and adding variety.
- Altering the melodic outline of the theme: This refers to changing the shape or contour of the main theme, which can create new melodies by using the same notes in a different order or pattern.
Substituting a new theme altogether is not an example of thematic development, as it involves introducing a completely different musical idea instead of developing the existing theme.
