Why is homophonic texture ideal for improvised ornamentation?

Homophonic texture is ideal for improvised ornamentation primarily because it features a clear distinction between a primary melodic line and accompanying harmonies. This structure allows the performer to embellish the main melody without the complexities that arise from multiple independent melodic lines that can occur in polyphonic textures. In a homophonic context, since one melody stands out supported by chords or harmonies, musicians can freely add ornamentation to enhance the expressiveness of that single melodic line.

In situations where two or more melodic lines are present, each line requires careful coordination to ensure that the added ornamentation does not conflict with or overshadow the other parts. This means musicians would need to plan their ornamentation in advance to maintain balance and coherence. Therefore, the simplicity of having a single melody surrounded by harmonies in a homophonic texture makes it particularly conducive to spontaneous improvisation and ornamentation.
