Fiddle with for a bit...Notice in the thread MPasini had a pattern that
worked on your example. However I modified your example to include
possibilities that could arise...And I'm not sure if I have got all of
these.
Here is the example I came up with:
____
B7 E A Am E
This is a line of a song
E
This is a line of a song
B7 E E7
This is line 7 of a song
A
This is a line of a song
E
This is the 9th line of a song
B7dim
This is a line of a song aug
E A Am E
This is a line of a song dim
C D E F G A B C#m
A small flower
C D E F G A B♭ C
Am I going
______
Depending on the result you desire either replace or extract with:
^([A-G\s])(?(1)([A-Gm679#♭iu\s]+)$)
