今天早晨闲来无事逛b站，看到有大佬用c++演奏了很多歌曲，然后心血来潮，就想着用python做一个，无奈，自己早年间学过的吉他的乐理知识早就忘得一干二净了，没办法，开展cv大法，找到了一首大佬编写的lemon，特此记录一下。

mid = mido.MidiFile()
track = mido.MidiTrack()
mid.tracks.append(track)

#meta_time = 60 * 60 * 10 / bpm

base_note = 60
track.append(mido.Message('note_on', note=base_note+base_num*12 + sum(major_notes[0:note]), velocity=96, time=0,channel=1))
