欢乐喜庆2020春节马上要到了，掌控贺新春，溯源中国年！
春节期间播放最多的是音乐就是春节序曲了，没有之一。
《春节序曲》是《春节组曲》的第一乐章，正式名称为《春节组曲 第一乐章.序曲》。经常被抽出单独演奏。是我国著名作曲家、音乐理论家李焕之基于延安时期的生活体验，在20世纪50年代创作的一部作品，展现的是当年革命根据地的人们在春节时热烈欢庆的场面。它的旋律曲调雅俗共赏，加之其表现的主题是非常具有群众基础的盛大节日，因而从它诞生之后，逐渐演变成了附加在”春节”之上的小传统。尤其是电视春晚流行后，此曲也更加为人熟知了。用此曲改编的音乐作品数不胜数，太多太多了，今天改编到掌控板上来，让掌控也来播放交响乐。
大家先欣赏一下交响乐的MV，主要听音乐啊，时间仓促画面临时凑的视频地址： https://www.bilibili.com/video/av81630102/
下面先上乐谱，大型交响音乐，乐谱还是很复杂的
交响乐，乐谱音域极宽，有变速（快板，中板），还有转调，下面是我转调的手稿，主要做下标记
下面附上整首音乐的代码，编这个曲子用了我四五个小时的时间，真的很麻烦，主要是错了不好定位，感觉比码程序代码都难很多，有快板、中板、转调我给巧妙的整合到一个序列中去了，还是很有创新的！

光有音乐还不行，配上画面才更完美，我本来做了一个128*64的动画，导出了3000多张pbm图片，上传到掌控板太慢了，传了半晚上也没传上去多少，最后偷懒了，挑了十几张图片，针对128*64的分辨率做了修正。
程序代码，程序很简单，实现了一边播放音乐，一边OLED屏每3秒换一张图片，里面穿插了两个小动画
最后是播放效果
