如何用matlab创作歌曲

clear;clc;
A4=440;%标准音A4
pt=44100;p0=pt/2;%频率
scale12=A4/2^(9/12)*2.^((0:11)/12);%十二平均律
map=[1 3 5 6 8 10 12];%七音符
%乐谱
score=[1 1 5 5 6 6 5,...do do sol sol la la sol-

'满天都是小星星'];%How I wonder what you are
%下面开始播放
for i=1:length(score)
fprintf(1,'%c',lyric(i))
wavplay(sin((1:rhythm(i)*p0)/pt*2*pi*scale12(map(score(i)))),pt);
if mod(i,7)==0
fprintf(1,'\n');
