Interface

<Jianpu

song is an array of note. highlightedNote is also a note. A note has a structure like this:

{
  "pitch": {
    "base": 60, // pitch. 60 represents Middle C. Each increment represents a semitone (half step)
    "accidental": 0 // -2: double flat, -1: flat, 0: none, 1: sharp, 2: double sharp
  },
  "duration": 12, // 8 represents a crotchet. So 12 means 8+4, which is one and a half crotchet (dotted crotchet)
  "options": {}, // set "slur" to "start" or "end" to indicate the start or end of a slur
  "lyrics": {
    "exists": true, // has lyrics on this note
    "content": "Row, ", // lyrics content
    "hyphen": false // append with hyphen or not
  }
}
