Time Signatures

Grade 4 · Music · Study Guide

Learn how time signatures tell musicians how to count and organize the beats in a piece of music.

In music, a time signature is a set of two numbers written at the beginning of a piece of music. It tells musicians how many beats are in each measure and what kind of note gets one beat. You will find the time signature right after the clef and key signature at the start of a staff.

The top number of a time signature tells you how many beats are in each measure. The bottom number tells you what type of note equals one beat. When the bottom number is 4, a quarter note gets one beat. When the bottom number is 8, an eighth note gets one beat.

The most common time signature is 4/4, which means there are four beats in each measure and a quarter note gets one beat. You count: 1, 2, 3, 4. This is so common it is also called common time and is sometimes shown with a 'C' symbol.

Another common time signature is 3/4, which has three beats per measure. This gives music a waltz-like feel — count: 1, 2, 3, 1, 2, 3. Many folk songs, lullabies, and dance pieces are in 3/4 time.

2/4 time has two beats per measure, giving it a march-like feel. Notes and rests in a measure must always add up exactly to the number of beats the time signature requires.
