👉 Underdrudgery, also known as underdrumming or underdrum, is a phenomenon in which a person's brain responds to music by performing repetitive actions. This can include things like tapping fingers on instruments, nodding or shaking head from side to side, or simply repeating phrases or words. The exact cause of this behavior is not fully understood, but it may be due to the way the brain processes and interprets musical information.
