Simple Time Signatures. In simple time signatures, the beat falls on undotted notes such as quarter notes, half notes, eighth notes etc. Also, every beat is divisible by two. In 4/4 (also referred to as quadruple metre) the basic beat is a quarter note. This beat can be split into groups of two. By that I mean, a quarter note divides into eighth notes and eighth notes divide into sixteenth notes. Another example of a simple time signature is 3/4 also referred to as triple metre.
rhythms to behave. This rule is called a time signature . Time signatures have two parts, a top number and a bottom number. The Bottom number tells us what type of note receives one beat. The number stands for a certain kind of note. To keep things easy, we will only work with the number 4, which stands for quarter note. The top number explains how many beats we can put into one measure of music. Again, to keep things easy, lets stick with 4. The next step helps us to understand the relationship between notes now that we have a rule. Fill out the Rhythm Tree diagram below. Write the name of the note in the left ...
