如何在不同的块中使用 lilypond 宏

Question

代码：

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\begin{document}
First variant

\begin{lilypond}
\version "2.17.27"
\language "english"
D = \relative d {d4 <f a d>}
A = \relative a, {a4 <a' c e>}
BassOne = {\D \A | \D \D |}
\new PianoStaff <<
  \new Staff  \relative f''{
    \time 2/2
    <f a>4 <f a> <e g> <e g> | <d f>4 <d f> <d f> <e g> |
  }
  \new Staff \relative{
    \time 2/2
    \clef bass
    \BassOne
  }
>>
\end{lilypond}

Second variant

\begin{lilypond}
\version "2.17.27"
\language "english"
D = \relative d {d4 <f a d>}
A = \relative a, {a4 <a' c e>}
BassOne = {\D \A | \D \D |}
\new PianoStaff <<
  \new Staff  \relative f''{
    \time 2/2
    f4 f e e | d d d e |
  }
  \new Staff \relative{
    \time 2/2
    \clef bass
    \BassOne
  }
>>
\end{lilypond}
\end{document}

输出：

由于有 2 个 lilypond 块，我必须复制此代码：

D = \relative d {d4 <f a d>}
A = \relative a, {a4 <a' c e>}
BassOne = {\D \A | \D \D |}

可以重复使用吗？
