1 The par of a course is the total number of strokes that a course designer assumes it will take a skilled golfer to finish a round, or 18 holes. 2  The par is usually around 70, or three to five strokes per hole. 3  The course rating and course slope are assigned by the United States Golf Association (USGA).
A Clef (from the French for key) is a musical symbol used to indicate the pitch of written notes. Placed on one of the lines at the beginning of the staff, it indicates the name and pitch of the notes on that line.
The grouping of strong and weak beats is called meter. You can find the meter signature (also called time signature) at the beginning of every music piece; it is the 2 numbers written after the clef. The number on top tells you the number of beats in a measure; the number at the bottom tells you what note gets the beat.
