A simplified arrangement of a composition

"Reduction" in music refers to the process of simplifying a complex musical composition or score to a version that is more manageable or playable by fewer instruments or voices. This technique is commonly used for educational purposes, rehearsal, or adaptation of larger works for smaller ensembles. Reductions aim to retain the essential musical elements and overall structure while accommodating the limitations of the performing forces.

In music, a "reduction" involves taking a composition that was originally scored for a full orchestra, choir, or larger ensemble and creating a condensed version that can be performed by a smaller group. For example, a reduction of an orchestral piece might involve transcribing the orchestral parts for a single piano or a small chamber ensemble.

Reductions are particularly useful for rehearsal purposes. They allow conductors, musicians, and singers to focus on specific parts and nuances of the composition before working with the full ensemble. This approach helps ensure that all performers are well-prepared and familiar with their individual contributions to the overall sound.

Additionally, reductions can be beneficial when performing music with limited resources or in smaller venues where accommodating a full orchestra or large choir might be challenging. They provide a way to retain the essence of a composition while making it feasible for a smaller group to present.

Music reductions require careful consideration and skill to capture the essential melodies, harmonies, and textures while accommodating the reduced instrumentation. Composers, arrangers, and transcribers often undertake this task to ensure that the reduced version remains faithful to the original work.
