Accidents happen… But losing the functionality of a hand or arm shouldn’t stop you from playing drums. Students at various levels can be challenged by choosing their own tempo. The cymbal section is also ad lib. i.e. the performer can improvise on their own between the cymbals or adhere to the notated rhythms while experimenting with the orchestration of the cymbals. The final section is ideally faster than primo tempo, but would be most effective if the performer remains in control without appearing frantic.
