music benefits

Builds self esteem!

Parents and piano students notice improvements in mood and emotional balance, creativity, attention, coordination, confidence and academic performance. Piano students also have an edge when learning other musical instruments.

In adults, piano study at an older age can lower blood pressure and dementia risk. There are also improvements in immunity and cognitive abilities. Some of Mary’s favorite students are adults!

When you play piano, your brain releases “happy chemicals” like oxytocin, dopamine, serotonin and endorphins that make you feel uplifted and less stressed.

Music is one of the oldest forms of communication and its relationship with society is profound. It brings communities together and helps individuals enhance their lives through playing an instrument. Music improves our well being.

Piano study at any age can potentially set the stage for a lifelong relationship with music as a creative, emotional and intellectual pursuit. It’s the highest art form, after all.


I had not had a real piano lesson before I met with Mary. Since I was 5 anyway…She has helped me to work on reading and finishing pieces–I have learned a great Bach piece, and have memorized it and love playing it–and definitely it was with Mary’s help that I was able to do that–something I didn’t expect I could do yet. She has a kind and patient approach which I really appreciate, and it’s clear that she also enjoys watching my progress, which is really a nice feeling. Thank you, Mary!
