Accompanist / Piano InstructorYuri
Accompanist pianist × piano instructor × web writer. I began piano lessons at age four and, inspired by my piano teacher, decided to pursue music. I went on to specialized music programs in high school and university, where I discovered the appeal of accompanying instrumentalists and singers. Currently, alongside teaching piano, I work mainly in my home region of Aichi as an accompanist for flute, voice, choir, and more. Through lessons, my students often introduce me to trending songs, and my hobby is trying anything on the piano—Japanese and Western pop, commercial jingles, and beyond. Since 2021, I’ve also been active as a web writer, covering music and a variety of other genres.
Former vocal coach specializing in Western musicRyo
Under the theme of “vocal skills that stand up on the world stage,” I have experience teaching as an online vocal coach specializing in Western music, and I usually listen to genres like nuevo flamenco, bolero, canzone, and R&B. In my teens, I questioned the idea that “foreign music equals English,” and started exploring songs from around the world. My commentary is characterized by a unique perspective shaped by listening to music of every genre, in every language, from every country. I mainly cover world music, so be sure to check it out!
