At 18 years old, Spokane Valley High School senior Alex Bityukov has learned to make all the strings of the piano sing together in harmony. “A lot of people don’t think you can tune a piano when you’re 18, or even 17,” said Bityukov, who has been learning the trade from Dan Loibl, also known as Dan the Piano Man, for the past five years. “I actually started tuning in houses when I was 17.”
