我目前正在开发一个 iPhone 应用程序，该应用程序需要显示歌曲的歌词以及吉他和弦。屏幕上的输出类似于以下内容：

在此处输入图像描述

我仍然想知道携带这种数据的最佳格式是什么（每行曲目中的歌词、和弦和时间戳）。我正在考虑使用这种格式的 JSON 文件：

{
      "lyrics": [
          {
              "text":"This is one line of lyrics",
              "startTimestamp":5000,
              "endTimestamp":5800,
              "chords":[
                  {
                      "symbol":"A",
                      "position":0.2
                  },
                  {
                      "symbol":"D#",
                      "position":0.8
                  }
                  ]
          },
          { ... },
          { ... }
       ]
}

另一种选择是使用 Chordpro 格式： http ://tenbyten.com/software/songsgen/help/HtmlHelp/files_reference.htm

但是这种格式没有带时间戳来同步歌词的显示和音乐，在iOS上解析似乎有点痛苦。还有其他有趣的选项我可以考虑吗，例如 HTML？

该应用程序将仅包含 12 首曲目的歌词。

I am also interested in this question. I'm creating a 'serverless' web page for my own catalog of songs using only HTML, CSS, and JavaScript.

I am also hoping to come up with a way to store the chord/lyric info in JSON. I am newer to this line of thinking, but I am hoping to organize the text lines as stanza's and tag them with "Chorus, Verse, Intro ... ", and then mapping them to chord progressions (kinda like an OOP approach).

So far I have come across lots of Music XML stuff, but that seems to be for more formal sheet music.

Right now I am experimenting with just storing the text in HTML and rendering it in a 'pre' tag.

I guess a simple solution would be to neglect exact word to chord timing and just render the appropriate chords on top of the appropriate line of lyrics.

    [A D#]
    'This is one line of lyrics'

Or ... maybe be could assign each line of lyrics a value of say 12 in length (like Bootstrap Grids, but could base this on number of beats per line including a divisor) and then assign each chord a 'slot' to fill in the line above?

So

Em7        G
  Today is gonna be the day
             Dsus4                  A7sus4
That they're gonna throw it back to you,

would be something like (where beat_of_measure = beat/2 % 4)

{
  "stanza1": 
      {
          "type": "verse",
          "line1":{
              "lyric": "Today is goinna be the day that they're", //4 beats subdivided = 8 length
              "start_beat": 1, //half a beat after Em7 chord
              "end_beat": 7},  
          "line2":{
              "lyric": "goinna throw it back to you"
              "start": 8 //goinna is right on beat 5, (think modulo 4)
              "end": 12}
       }
          "verse_chords":[
              {
                  "symbol":"Em7",
                  "chord_beat":0 //starts at very beginning
              },
              {
                  "symbol":"D#",
                  "chord_beat":4
              },
              {
                  "symbol":"Dsus4",
                  "chord_beat":8
              },
              {
                  "symbol":"A7sus4",
                  "chord_beat":12
              },

              ],

   bla bla bla
   ]
}

Sorry for this ridiculous answer!
