钢琴包中的和声小调音阶结构

Question

需要打印钢琴键盘包中的字母音符，基本代码如下：

\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\usepackage{polyglossia}
\setmainlanguage{english}

\usepackage{musixtex} 
\usepackage{piano} 
\usepackage{float} %Paquete para posicionar Tablas

\begin{document}

\begin{figure}[H]
    \centering
    \keyboard[Ao][Bo][Ct][Dt][Et][Ft][Gst][At]
    \caption{Harmonic minor scale structure in A}
    \label{Harmonic}
\end{figure}
  
\end{document}

期望的输出如下：

Answer 1

该piano软件包非常有限。以下是完整手册：

此包将 \keyboard[1][2]..[7] 命令添加到您的项目中。使用时，它会在您的文档上绘制一个小型 2 个八度钢琴键盘，最多可突出显示 7 个键。

按键：Co、Cso、Do、Dso、Eo、Fo、Fso、Go、Gso、Ao、Aso、Bo、Ct、Cst、Dt、Dst、Et、Ft、Fst、Gt、Gst、At、Ast 和 Bt。

建议使用：\begin{figure}[thpb]\ \centering
\keyboard[Co][Eo][Gso][Ct][Et] \caption{C aug chord}
\label{Chord1} \end{figure}

请注意，您最多可以突出显示 7 个键。空键盘在 TikZ 图片中使用起来有些困难，如下所示：

\documentclass[tikz, border=1cm]{standalone}
\usepackage{piano}
\usetikzlibrary{arrows.meta}
\tikzset{
blackkey/.style={
white, scale=0.8,
append after command={\pgfextra{\tikzset{every label/.append style={white, scale=0.8}}}}
}}
