I've been banging my head all afternoon trying to derive a regex the will
identify lines (of a song) that contains chords.
eg
E 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 a line of a song
A
This is a line of a song
E
This is a line of a song
B7
This is a line of a song
E A Am E
This is a line of a song
There could be spaces before or after the chord names and the only way I
can think to distinguish chords from regular words is that chords are
likely to have more than one space after them - or a newline
I've got as far as [A-G][6|7|9|m|#|♯|b|♭|aug|dim]
but the spaces and newlines have me flumoxed.
Can anyone help?
