Writing variations in ABC
Sometimes in a reel, for example, bars 5 & 6 of the B part are played differently in the two repeats.
I have seen such tunes written (for example in Gerry O’Connor’s banjo book), where the
two versions of bars 5 & 6 are marked like 1st and 2nd endings (i.e. with 1 ————————, 2 ———————)
but then bars 7 & 8 follow them. This can also be use to show a variation.
If I use [1 || [2 || in ABC the rendered sheet music looks just like those books do
(except for the double bar line), but apparently the tool that converts ABC to midi for playback,
totally misunderstands such things.
I just posted two tunes like that and faced ridicule for the result.
(I also got the key signature wrong in one of them, writing Emaj when it should have been Emix).
Without using the [1, [2 marks, the only way to write the tune is to write out the 8 bars of the B part twice
changing bars 5 & 6 in the second 8 and keeping bars 1,2,3,4,7,8 the same.
It seems to me that the music is more compact and easier to see that only two bars have changed
if the [1 , [2 thing would work in the middle of a part.
Are there any ABC tools that allow that?
