How would sheet music be written for vocals in a right-to-left language (Hebrew or Arabic)? It seems there would be a clash between the left-to-right convention of sheet music and the right-to-left of the language.
One possibility that is seen in Hebrew occasionally is to print a mirrored score (including all symbols) apart from the lyrics. Most of the time, however, you just get the score straight, and the lyrics left-to-right, syllable by right-to-left syllable. I would imagine that it takes some practice singing that.
