Simple time is any meter whose basic note division is in groups of two. If you count the notes in the measures, you will see that there are four quarter-notes worth of time per measure. Technically, these measures have four quarter notes in them as well, but this one is called “ Cut Time,” hence the C being slashed or “cut.” This “Cut Time” change to “Common Time” means it goes twice as fast, so instead of the quarter note getting the beat, the half note gets the beat! The is like 2/2, just written different and used for faster tempos than 2/2.īelow is an example from the opening of Edvard Grieg’s Peer Gynt Suite, “In the Hall of the Mountain King.” This excerpt is in marked in Common Time with a big C, which means 4/4. It looks a lot like the “Common Time” signature, except it has a slash through it. The 4/4 time signature is so common that it actually has two names and two forms, the first being 4/4, and the second being the, literally called “ Common Time.” So whenever you see the in music, you know that it is actually 4/4 time (which has how many notes of what kind of length?).Īnother prevalent time signature is the. The above steps are how you figure out the notes and beats of most time signatures, but what about the two time signatures that are letters? As a matter of fact, the two letter time signatures are actually shorthand and variations for the most common numerical time signatures, 4/4 and 2/2. In 3/1 time, so we have 3 notes of a 1/1 length, so 3 whole notes! In 4/2 time, each measure has 4 notes of 1/2, so we have 4 1/2 notes: In 9/8 time, you know that in every measure there are 9 notes in a 1/8 length. Therefore, you know that there are two quarter notes worth of time in every measure: Take the 2/4 time signature for example - with the 2 on the top of the time signature you know there are 2 beats for one measure, and this leaves you with a fraction of 1/4 -a quarter, the note-length the time signature is indicating to you then is a quarter note. If you look at the American note names from the chart above, there is a fun little trick to it: The bottom number of the time signature indicates a certain kind of note used to count the beat, and the top note reveals how many beats are in each measure. As you saw in the time signature examples above, each time signature has two numbers: a top number and a bottom number: 2/4 time, 3/4 time, 4/4 time, 3/8 time, 9/8 time, 4/2 time, 3/1 time, and so on. The number of notes allowed in each measure is determined by the time signature. For example, a double-whole note would last as long as eight quarter notes! This chart also mentions the length relationship between the note values.Īs the notes in the various metric breakdowns get bigger or smaller, the equivalent relationships continue. The most common notes which are used to make the short and long rhythms in the various meters are included in the chart below, beginning with the longest held notes and going to the shortest. A “ barline," or measure line, is where the five horizontal lines of a staff are intersected vertically with another line, indicating a separation:Įach measure has a specific number of notes allowed to be placed in it, and that number of notes is dependent upon the time signature. In musical scores, we organize the music into “ bars” or measures. Musicians learn how to play these rhythms in the context of each piece by using the time signature. Rhythms are the lengths of the notes in the music itself - which notes are long and which notes are short. That said, there is another way that musicians also discuss how music moves through time, and that is through rhythm. Meter is the comprehensive tool we used to discuss how music moves through time. The methods for classifying the various time signatures into meters is discussed in detail later in this article. When discussing music, the terms "time signature" and "meter" are frequently used interchangeably but time signature refers specifically to the number and types of notes in each measure of music, while meter refers to how those notes are grouped together in the music in a repeated pattern to create a cohesive sounding composition. The organizational patterns of beats, as indicated by the time signature, is how we hear and/or feel the meter of said piece. The time signatures give us a way to notate our music so that we can play the music from scores, hear its organizational patterns, and discuss it with a common terminology known to other musicians. This organization of music through time is managed in the Western music system through time signatures. Hence, music is sound organized through time. Fundamental to the definition of music itself is that music must move through time-it is not static.
