2025/05 ― I wish I had taken music in high school. I would have learned about the instruments in an orchestra. Well, I got a rare opportunity to sit behind a harp. It has 47 strings. The red strings produce the note C and the blue strings produce the note F. The strings play the C, D, E, F, G, A, B of the C scale. To play accidental notes like F# or B♭, you have to either change the tuning or use a pedal.
