【OI无关】求一首曲子的名字

RT，

很久以前听的了，就是不知道名字

谱大概长这样↓

\begin{matrix} \underline{5~^\#6}~\dot{1}~\underline{5~3}~4~|~7~\underline{5~4}~\underline{3~2}~1~|~\underline{1~7}~1~\underline{2~3}~4~|~2~\underline{3~2}~\underline{3~4}~5~|&\\ \color{white}\underline{5~^\#6}~\dot{1}~\underline{5~3}~4~|~7~\underline{5~4}~\underline{3~2}~1~|~\underline{1~}\color{black}\cdot\color{white}~1~\underline{2~3}~4~|~2~\underline{3~2}~\underline{3~4}~5~|&\\ \underline{5~^\#6}~\dot{1}~\underline{5~\dot{1}}~\dot{2}~|~\underline{6~\dot{2}}~\dot{3}~\dot{2}~\dot{1}~|~\underline{\dot{1}~\dot{2}}~\underline{\dot{3}.~}\underline{\underline{\dot{3}}}~\underline{\dot{3}~\dot{4}}~\dot{2}~|~\underline{\dot{1}~7}~\dot{1}~-~-~|&\cdots \end{matrix}
