I think that is the main reason why the violin family has "only" four strings on its various instruments. The violin, for example, is tuned GDAE going upward. If one added another string -a fifth again-, it would be B, and then one would have to chose its "temperament" in order for it to be in tune with the Gs played on other strings.. </blockquote> </body> </html>
