Time Signature

Time signature or meter signature is a sign in musical notation which is written in the beginning of the music piece immediately after the clef and the key signature and it defines the amount and type of notes that each bar contains. It is written either as a fraction (number/number) or as a time symbol and it provides information about the metric characteristic of the piece.  The time signature tells three things:

  1. The note value which represents one beat
  2. The type of beat divisions ( compound duple, compound triple, compound quadruple| simple duple, simple triple, simple quadruple) which will be discussed in the next posts
  3. The number of beats in each measure
