         Note::new("D4".parse().unwrap(), ND::Eighth),
         Note::new("Eb4".parse().unwrap(), ND::Eighth),
         // |
         Note::new("D4".parse().unwrap(), ND::HalfDotted),
         // |
         Note::new("C4".parse().unwrap(), ND::Eighth),

         Note::new("Ab4".parse().unwrap(), ND::Quarter),
         Note::new("G3".parse().unwrap(), ND::Eighth),
         Note::new("F3".parse().unwrap(), ND::Eighth),
