Playing the piano develops fine motor skills, hand-eye coordination, and bilateral coordination which are crucial for walking, handwriting, clapping hands and many other daily tasks.
Singing activates the relaxation response. The diaphragmatic breathing required for singing triggers the vagus nerve, a key part of the parasympathetic nervous system.
Singing consistently lowers cortisol, the primary stress hormone, as proved by multiple studies measuring saliva levels before and after vocalization.
A 2017 Royal College of Music study found a marked decrease in cortisol following a singing session, while research on cancer patients and carers confirmed that singing alters cortisol level alongside other stress related signs.
