Sound advice because that at least is unambiguous. The trouble is that with all questions like this, the more you probe the more you discover that there is no such thing as "standard" music notation. I would be very surprised if the advice above has always been adhered to down through the ages by all musicians. If it has not been then it opens the question "what did the guy who wrote this mean by it?" L. To subscribe/unsubscribe, point your browser to: http://www.tullochgorm.com/lists.html
