I started piano almost five years ago. It has definitely helped me understand some music theory better, especially the fingerings for different keys and ideas of whole and half steps. It also helped me realize patterns of stressing, self criticism, and pushing myself beyond reason that had been destructive with my violin playing when I was young. I could recognize my part in the dynamics that caused me to quit violin when I was young and to recognize that I grieved the loss of my playing. Ultimately resulted in restarting violin almost 3 months ago after a 48 year break!
