Learning all the intricacies of abc notation might be unnecessarily sophisticated. Just put a barline/ in before the first note of each group of four beats.put a dot after every note that lasts a whole beat. No dot after a note that lasts a half beat. That will do fine. I'll put a guess in here.It bears little or no resemblance to the tune I know for "Going to the garden to eat worms" but I just wonder if this might be another tune for the same words?
