This plugin assists in the creation of staffless lead sheets, also called chords sheets. 
It defines a [chordsandlyrics] shortcode which can be used in your post or page text. 
It does not require any editing of your template files.
Text appearing between the [chordsandlyrics] and [/chordsandlyrics] tags will be 
formatted for chord symbols written in square brackets (eg. [Cmaj]) embedded 
inline within lyrics. 
It will then display the chord symbol at the same horizontal position above the lyrics. 
For example:
[C]Oh [F]say can you see…
will be reformatting using HTML table to display as
C F 
 Oh say can you see…
with the C correctly positioned over “Oh” and the F positioned over “say”. 
The commonly used alternative is to use fixed fonts which isn’t very attractive. 
This syntax is similar to the that used by ChordPro/Chordii.
Features:
<ul>
<li>Format lead sheets, keeping chord symbols above the correct lyric.</li>
<li>Appearance options page allows each end user to select Lyrics only 
or Chords And Lyrics display via their profile (user’s option page).</li>
</ul>
<h3>Directions for Use</h3>
<ol>
<li>Create Posts or Pages containing the [chordsandlyrics] … [/chordsandlyrics] tags.</li>
<li>Embed chord symbols within square brackets inline with lyrics within these tags. 
For example: 
 [chordsandlyrics] 
 [C]Mary had a little lamb, [G]little lamb, [C]little lamb. 
 [C]Mary had a little lamb whose [F]fleece was [G]white as [C]snow. 
 [/chordsandlyrics] 
Note that chords can appear in the middle of lyric words.</li>
