The article discusses three essential things that every drummer who lives in an apartment should practice. These include practicing rudiments, using a practice pad, and using low-volume drumming techniques. By focusing on these aspects, apartment drummers can improve their skills without disturbing their neighbors. Practicing rudiments helps drummers develop their technique and speed, while using a practice pad allows for quiet practice sessions. Additionally, using low-volume drumming techniques, such as using brushes or rubber drum mutes, helps reduce the overall noise level. Overall, these practices enable apartment drummers to continue their musical development while being considerate to those around them.
