Happy Farmer, from Suzuki Book 1. I started learning this piece on Feb 22, 2018, and have practiced it approximately 75-80 times. Its been a week since I last played it, and this is a cold take, evidenced by my memory failure partway through :)
It’s taken me a long time to appreciate this piece – I struggled with the bowing and the rhythm of this one for months, but once you get it, its actually really fun to play.
