How to Tell if Music is in Simple Time or Compound Time - Music Theory
TLDRThis video explains the difference between simple time and compound time in music. Simple time has 2, 3, or 4 beats per bar that divide into two, while compound time has 6, 9, or 12 beats per bar that divide into groups of three. The upper number of the time signature indicates how many beats; the lower number indicates the beat type. Examples are provided of 2/4 and 6/8 time signatures. The beats naturally divide into two in 2/4 (simple duple) but three in 6/8 (compound duple). Musical examples demonstrate the different feels - simple time is straightforward, compound time more lilting. Counting remains in two, but subdivision differs.
Takeaways
- 🎵 Simple time signatures have 2, 3, or 4 as the upper number, indicating simple time.
- 🎶 Compound time signatures have 6, 9, or 12 as the upper number, indicating compound time.
- 📖 In simple time, the upper number of the time signature tells you how many beats are in a bar, and the lower number tells you what kind of beats they are (e.g., crotchet or quarter note beats).
- 📚 In compound time, although the time signature might indicate a certain number of beats (e.g., six quavers in 6/8), it's understood as beats divided into groups of three, leading to a different feel.
- ✏️ Every beat in simple time naturally divides into two equal parts.
- ❇️ Every beat in compound time naturally divides into three equal parts, giving a lilting quality.
- 🎸 Simple time and compound time can have the same number of beats in a bar but are differentiated by how those beats subdivide (into twos for simple, threes for compound).
- 🎤 A piece in simple time will have a straightforward, even division of beats, while a piece in compound time will feel more flowing or swinging due to the triplet subdivision.
- 👀 Hearing the difference between simple and compound time involves recognizing whether beats divide into two or three.
- 💿 The practical demonstration of tunes in 2/4 (simple duple) versus 6/8 (compound duple) time illustrates the theoretical differences through their distinct rhythmic feels.
Q & A
What are the two main ways the video will explain how to identify simple vs compound time?
-The video will explain how to identify simple vs compound time both by how it looks on paper using time signatures, and by how it sounds when played.
What are the time signatures that indicate simple time?
-Time signatures with 2, 3, or 4 as the top number indicate simple time.
What are the time signatures that indicate compound time?
-Time signatures with 6, 9, or 12 as the top number indicate compound time.
In simple time, how does each beat naturally divide?
-In simple time, each beat naturally divides into two equal parts.
In compound time, how does each beat naturally divide?
-In compound time, each beat naturally divides into three equal parts.
What is the process for determining the meter in compound time?
-For compound time, take the number of eighth notes indicated, divide them into groups of 3, and then determine how many main beats there are based on the groups of 3.
What are the differences in feel between simple duple and compound duple meter?
-Simple duple has a straight feel with beats dividing in two. Compound duple has a lilting feel with beats dividing in three, even when the main beat count is the same.
How can you hear the difference between simple and compound meters?
-Listen for whether the beats and subdivisions feel like they naturally divide in two or in three - simple divides in two, compound divides in three.
What are the differences between 2/4 and 6/8 time signatures?
-2/4 indicates 2 quarter note beats per bar in simple time. 6/8 indicates 6 eighth notes divided in 2 groups of 3, creating 2 dotted quarter note beats per bar in compound time.
Why is compound time also called complicated time?
-Compound time is slightly more complex than simple time because you have to take the extra step of dividing the written notes into groups before determining the main beat.
Outlines
😀 Explaining the difference between simple and compound time signatures
The paragraph explains the difference between simple time signatures like 2/4, 3/4, 4/4 where the beats naturally divide into two and compound times like 6/8, 9/8, 12/8 where the beats naturally divide into groups of three. It gives examples of counting and feeling the difference between a simple duple tune in 2/4 and the same tune adapted to 6/8 compound duple time.
😀 Hearing and feeling the difference between simple and compound time
The paragraph plays the same simple tune in 2/4 and an adapted version in 6/8 to demonstrate the difference in feel - the 2/4 feels straight and divides in two while the 6/8 feels lilting and divides in threes. It reinforces that while they feel different, both versions have two main beats per bar.
