For those of you who want to add subtitles at the proper height...
- From the default top staff (upper/lower vertical size is 12), the Staff Position of the Author, Lyricist line is almost exactly 21. If you have the same text below it, it will create a slight [shadow=black,right]shadow effect[/shadow].
- To go down an additional row, subtract 5 (approximately) from the staff position. (This measurement was created with Staff Italic. This will vary depending on which font you use.)
