根据上述代码,补充生成一段音乐的代码如下:
```python
l = sum(rhythm)
speed = 100 # 曲速(每分钟speed拍)
t0 = 60 / speed / 4 # 16分音符占t0秒
music = zeros(1, int(l * t0 * f + 5 * f - 1))
position = 1
n = 1:length(music)
t = n / f
for i in range(len(ftune)):
if mod(tune[i], 1) != 0: # 休止符:音量同步衰减一半
music[position:position + 3 * f - 1] = music[position:position + 3 * f - 1] * 0.5
elif mod(rhythm[i], 1) != 0: # 延音符号开始:a=0.01,b=2,衰减变慢
music[position:position + 3 * f - 1] = music[position:position + 3 * f - 1] + \
0.8 * mypiano(8000, ftune[i], 0.01, 2)
elif i != 0 and mod(rhythm[i - 1], 1) != 0: # 延音符号之中:a=0.05,b=3,开始变慢
music[position:position + 3 * f - 1] = music[position:position + 3 * f - 1] + \
0.4 * mypiano(8000, ftune[i], 0.05, 3)
elif rhythm[i] >= 8: # 较长音符(此为全音符),a=0.01,b=1.5,衰减变慢
music[position:position + 3 * f - 1] = music[position:position + 3 * f - 1] + \
mypiano(8000, ftune[i], 0.001, 1.5)
else:
music[position:position + 3 * f - 1] = music[position:position + 3 * f - 1] + \
mypiano(8000, ftune[i], 0.001, 3)
position = position + int(rhythm[i] * t0 * f + 1)
music = 0.75 * music / max(music) # 音量调节
clf()
plot(t, music)
title('天空之城')
sound(music, 8000)
audiowrite('天空之城.wav', music, 8000)
```
请注意,这段代码是基于Matlab语法编写的,若要在其他编程语言中运行,可能需要进行一些适当的修改。另外,请确保mypiano函数的实现与上述代码中使用的一致,以便正确生成音乐。
