the motion given by early conductors to guide an instrumental ensemble was called
Conducting An early form of conducting is cheironomy, the use of hand gestures to indicate melodic shape. This has been practiced at least as far back as the Middle Ages. In the Christian church, the person giving these symbols held a staff to signify his role, and it seems that as music became rhythmically more complex, the staff was moved up and down to indicate the beat, acting as an early form of baton.
Timpani Timpani (/ˈtɪmpəni/;[2] Italian pronunciation: [ˈtimpani]) or kettledrums (also informally called timps)[2] are musical instruments in the percussion family. A type of drum, they consist of a skin called a head stretched over a large bowl traditionally made of copper. Most modern timpani drums, such as pedal timpani are able to, and are designed to be, tuned easily to specific pitches, often during sections of music; the example being tuned by a movable foot-pedal. They are played by striking the head with a specialized drum stick called a timpani stick or timpani mallet. Timpani evolved from military drums to become a staple of the classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock.
