Nowadays, everybody uses the composition of Salomon Sulzer (who lived in the mid 19th century) for Vayehi Binsoa and the other tefillot of the torah service. This is generally taught as such, and is used across the board, from Litvish shuls, all the way to Reform temples. What nusach was used before Sulzer lived, and why don’t we use it? (I find Sulzer and Lewandowski to be the most gifted composers of synagogue music, so my question is not one of practical usage).
