A pedal point is a sustained note, usually in the bass, that remains constant while harmonies change above it. This technique creates tension and stability within a piece, allowing for contrasting harmonic developments. Pedal points are often used in harmonic improvisation to anchor the musical texture, providing a foundation for improvisers to explore different chord progressions.

Review Questions
How does the use of pedal points enhance harmonic improvisation?
Pedal points enhance harmonic improvisation by providing a stable tonal center that musicians can navigate around. This stability allows for greater exploration of harmonies above, encouraging improvisers to experiment with various chord changes while still having a reference point. The tension created between the sustained note and the changing harmonies adds depth and complexity to the music, making improvisational choices more impactful.
Discuss how pedal points can affect the emotional impact of a piece during improvisation.
Pedal points can significantly affect the emotional impact of a piece by establishing a strong sense of grounding amidst harmonic changes. As musicians improvise over a pedal point, the sustained note can evoke feelings of tension and resolution, influencing how the audience perceives the overall mood. This technique allows performers to create dramatic contrasts and build emotional narratives through their improvisation, effectively using the stability of the pedal point as a springboard for expressive musical ideas.
Evaluate the role of pedal points in shaping musical texture and structure during harmonic improvisation.
Pedal points play a crucial role in shaping musical texture and structure by serving as an anchor around which other musical elements revolve. In harmonic improvisation, they allow musicians to focus on developing melodies and exploring various harmonies without losing sight of a cohesive framework. This technique encourages collaboration among performers as they build off the established pedal point, creating layers of complexity while maintaining unity within the piece. Ultimately, pedal points help define the character and direction of an improvisational performance.
