Drums require a very high degree of hand-eye coordination, gross and fine motor control, and temporal & spatial reasoning. It’s also the most physical of all instruments.
As a result, it’s not uncommon for drummers to also be strong in math and physics, be good project planners, and also be natural athletes.
The biggest benefit is likely the physiological benefits of rhythm – drummers ‘feel’ the music they’re creating more than any other because of the sheer force involved; and we know from research that intensive dancing, as well as drumming, can release massive amounts of dopamine and serotonin – two hormones critical to our sense of happiness, wellbeing, and reward.
