Double strokes refer to a drumming technique where a drummer plays two consecutive notes with one hand before switching to the other hand. This technique is commonly used in various styles of music, allowing for faster and more fluid rhythms. It is often practiced with a metronome to develop speed and precision. In the context of percussion, double strokes can be applied on different instruments, such as the snare drum or timpani. Mastering this technique is essential for drummers, as it enhances their overall coordination and ability to perform complex patterns in pieces of music.
