In modern notation, it is used in place of 2 and is called alla breve or, colloquially, cut time or cut common time. In compound meter, subdivisions of the main beat the upper number split into three, not two, equal parts, so that a dotted note half again longer than a regular note becomes the beat unit.
Compound time signatures are named as if they were simple time signatures, in which the one-third part of the beat unit is the beat, so the top number is commonly 6, 9 or 12 multiples of 3. It has a basic feel of Bold denotes a stressed beat :. Each quarter note might comprise two eighth-notes quavers giving a total of six such notes, but it still retains that three-in-a-bar feel:.
Time signatures indicating two beats per bar whether they are simple or compound are called duple time; those with three beats to the bar are triple time. To the ear, a bar may seem like one singular beat. Terms such as quadruple 4 , quintuple 5 , and so on are also occasionally used.
Correspondingly, at slow tempos the beat indicated by the time signature could in actual performance be divided into smaller units. Other time signature rewritings are possible: most commonly a simple time signature with triplets translates into a compound meter.
Not for the faint of heart, if you decide to learn it, it is at least a short piece. Many songs and classical pieces do this. You only read across each page once as everything on the page is happening at the same time. Notice that the first time signature is The time signature changes often in this piece.

In duple meters then, the second beat is weak and any subdivisions of the beat are weaker still. In quadruple meters, beat three of the measure is actually stronger than beat two, but not quite as strong as beat one, and beat four should lead into the next downbeat beat one of the next measure.
Triple time starts with a strong beat one, has a weak beat two, and then begins to build on beat three leading to beat one again. Understanding the beat hierarchies of the different time signatures can help you to interpret repertoire, especially those that use minimal articulation.
However, there are no phrase markings and some musicians who have studied Baroque performance practices have argued for sections of this piece being in two instead of three. The particular Telemann example above, when performed with a changing beat hierarchy, can be an example of a metric and rhythmic technique called hemiola.
Hemiola is a two against three subdivision of beats being played against — and right next — to each other. Another way to disrupt the beat hierarchy of meters in music is to use syncopation.
Syncopation is the rhythmic shifting of the accented beat from the traditionally strong beats of one and three. In most cases this is done by a really short note on the downbeat which is immediately followed by an accented long note, or having a tie to an un-articulated downbeat, so that the downbeat gets completely lost. From the very first verse, the melody line bounces quickly off the sixteenth-note downbeat onto the accented eighth-note.
Without the score or the repeated eighth-note chords in the left hand of the piano, you would not know where the downbeats were or be able to track the movement of the measures as easily!
We have all of these different meters and possibilities for subdividing meters to fit the wide variety of music we have! Essentially, different kinds of music require different Simple or Compound time signatures and duple or triple meters. When we connect the music to how it is or was supposed to be used, we find some of the answers to this.
Take a March for example: marches are meant to be, well, marched to, in strict time, and as humans we only have two legs! So out of necessity, marches have to be in a duple or quadruple time. Dance music is another example of music that has to be in a specific meter. Most dances throughout history have had a prescribed number of steps and the music that accompanies the dances must match. For example, waltzes have to be in triple time because they follow a pattern of three steps before repeating the cycle.
The choice of meter and note length provided in the time signature is also a possible indicator of tempo. So, that's how you read time signatures! Many are interchangeable and can sound the same, but have slightly different origins or uses. Meters are how composers organize music through time and communicate that organization to the performers.

Common time and cut time. Are you allowed to have notes of different duration to the one identified in the bottom of the signature? How does that work? Whats the rule an why is this done. In compound time, each individual beat gets divided into three notes rather than two. In cut-time, if the eighth note were to get the beat instead of the quarter note, then the music would move twice as slow, as in, you would double the number of beats in each measure—making it twice as long to get through.
The rhythms stay the same in proportion to each other, but they go twice as fast. To go twice as fast as the quarter note beat, you would need a beat that fits two quarter notes in length, and that note, based on the diagram in the article, is a half note. Regarding the Peer Gynt Suite questions, you are allowed to have notes of different duration to the one identified in the bottom of the time signature.
The number at the bottom of the time signature simply tells what type of note gets the beat so that the musician knows how to interpret the rhythms of the notes. If you could only have the note-lengths that are indicated by the bottom of the time signature, then there would be no difference in rhythms—no long notes, no short notes, all the notes would have the same duration in every piece.
The eighth notes of the Peer Gynt Suite are grouped in 4 and then 2 because of the time signature. The 4 and 2 groupings reinforce that this time signature is a simple time signature and when you have a series of eighth notes then, you can only group them in groups of four or two. If they were grouped as a group of 6, that would indicate compound time and a different subdivision of the beat. That is why the first four eighth notes are grouped together—the four eighth notes equal the same length as one half note, which is one beat in cut time.
The next two eighth notes are grouped together because they are on the next beat of the measure, but as they are eighth notes, they cannot be barred with the quarter note that follows. And these two eighth notes and the quarter note make up the second beat of the measure.
Hey Laura, it depends on the piece. Both time signatures have the same number of quarter notes per measure. Many swing band arrangements use the cut time time signature. However, we count off 1,2,1,2,3,4 and play the music as if the time signature was originally in common time or in 4,4. Why is that? Any thoughts?
The only difference is the way the beats are felt with the stress on 1 and 3 as opposed to every quarter note pulse. Thanks for the comment! It seems to me that we have 2 symbols that represent 3 variables length per base note, base notes per beat, and beats per measure. The 2 symbols provide a compact notation, but is can be more confusing to people who are new to music signatures.
Over the years, has anyone considered time signatures that make all three variables explicit and which have accommodations for uneven time signatures? I was thinking of something like the following:. Greetings Dennis and thank you for your question! In the twentieth and twenty-first centuries, a lot of composers and theorists have come up with more explicit and less explicit time signatures to use in their scores.
However, each of these is unique to the composer; there is no universal agreement on anything that works better than the current system.
