Today, I participated in the practice of a citizen orchestra for the first time in several years from the standpoint of teaching stringed instruments. Their passion and seriousness, which was about to go live in July, made me feel joyful of vitality and fulfillment, even though I was happy just to hear the live sound in this covid-19 whirlpool. It was quite a tight time schedule to practice while ventilating diligently, but I hope it helped even a little.
