What is the proper sequence of percussion instruments?

The proper sequence of percussion instruments typically starts with the timpani, followed by other percussion instruments, and then keyboard instruments such as the piano or harp. This sequence is based on the standard classification of instruments.

Timpani, or kettledrums, are categorized as tuned percussion because they produce definite pitches and are often used in orchestral settings. Following the timpani, "other percussion" refers to a wide variety of instruments such as snare drums, tambourines, cymbals, and marimbas, which provide rhythm and color within ensemble pieces. Lastly, the options for keyboard percussion, like the piano and harp, usually come at the end of the sequence.

This organization reflects a general approach used in music education and orchestration, where instruments are grouped by their category and function within a piece of music. The sequence emphasizes the role of tuned percussion first, underscoring their melodic contributions before moving to the broader category of percussion and finally to keyboard instruments.
