Discussion 4a - Simple Meters

Class Discussion

“What is meter?”

• How we organize strong and weak pulses. Relating beats to the word pulse allows non-musicians to understand a beat.

Hierarchy of rhythm:

• Measure

• Beat - primary pulses

• Division - a division of a beat is the next simplest fraction (according to the type of meter).

• Subdivision - a subdivision is half of the division.

Labeling Meters

• Duple, triple, and quadruple

  • Duple meter is when the measure is divided into two strong beats.

  • Triple meter is when the measure is divided into three strong beats.

  • Quadruple meter is when the measure is divided into four strong beats.

• Simple meter is when the beat is divided into two equal parts.

• Compound meter is when the beat is divided into three equal parts.

“What do time signatures mean?”

• Top number: how many beats the measure is divided into in most cases (this breaks with some compound meters).

• Bottom number: what note value gets the beat.

“How do we count rhythm?”

• The beats get counted with numbers. Divisions get counted with “ands”. Subdivisions get either “e” or “a”.

• Simple quadruple time is counted “1 e and a 2 e and a 3 e and a 4 e and a”.

In Ideal music notation, every beat is shown. There are often implifications to have less ties.

What is rhythm?

• A division of the beat. (What’s a beat? A division of time…etc etc forever and ever)
• Rhythm is the temporal aspect of music

What does rhythm communicate?

• “When you play what”
• “How long you play what when you play it”
• “When and when not”…sound and silence…when things start and stop (especially the “and stop” part)

What do time signatures represent?

• Meter!
  • Meter -> Beats -> Division -> Subdivision

What’s a measure?

• A defined space that can only hold as many beats as the meter allows
  • A meter is defined by the beats!
  • A measure is our basic unit of meter (like inches into feet)

What is a regular meter?

• Can be divided into two? (Nope, too specific)
• Beats are divided evenly? Something is divided evenly?
• All the beats are the same length
  • Examples: 4/4 and 3/4 are regular, whereas 5/8 is irregular…unless the tempo is eighth note = whatever

**What is an irregular meter? -Have uneven beats within one measure (5/8 as 2+3 as an example). -Not like mixed meter: As an example, alternating between two(or more) regular and/or irregular meters. “America” from West Side Story (switches between 3/4 and 6/8).

What is a simple meter?

• Any time signature that has a 2, 3, or 4 in the denominator? (No: on the right track, though!)
• Beats hold equal value (No: this is a regular meter)
• Number of beats in measure = numerator? (Not quite: getting into the top/bottom number meanings, though)
• Basic division of a beat is 2

What do the top and bottom numbers mean in a simple time signature?

• Top = number of beats in 1 measure
• Bottom = note value that “gets” the beat
• What do we mean by “get”? How do we explain this to beginning musicians?
  • “How many” (top) and “what kind” (bottom)
  • Think of it as an actual fraction. Replace the top number with a 1 and it will reveal what kind of note is the beat

What do duple, triple, and quadruple mean when describing a meter?

• How many beats are in a measure. Duple has 2, triple as 3, etc. Phrasing is “simple x,” for example 4/4 is simple quadruple.

What is the “theoretically ideal” rhythmic notation of beaming in simple meters?

• Ideal: show where the beats are, common: easier to sight read? (Yes…though the second part’s subjective)
• Why is this helpful in a theory class with a lot of analysis?
  • Can clearly see every beat, makes it easier to discuss
  • Being able to see every beat can make it easier to stack chords when analyzing. You can see all the notes in each beat, so you are less likely to miss a sustained note from a previous beat.

A list of common meters in simple duple, triple, and quadruple:

• Quadruple: 4/32, 4/1
• Basicaly: you can have “simple x-uple” for any numbers of beat! Simple quintuple, simple octuple, etc.

The common beat-counting system that we’ll be using in this course:

• 1 e & a 2 e & a …
• For Triplets, we will use la li (ie 1 la li 2 la li etc.)
• The reason we are using these is because we can point out a certain sixteenth note or eighth note triplet without much effort or confusion.

Further Reading

From Open Music Theory

Rhythm refers to the combination of long and short durations in time. Durations are notated with either unfilled or filled noteheads. Unfilled noteheads can appear with or without a stem; filled noteheads always appear with a stem. Flags can be added to the stems of filled noteheads; each flag shortens the duration by half.

Rests

Rests represent silence in musical notation. For each durational symbol there exists a corresponding rest.

Dots and ties

Dots and ties allow for basic durations to be lengthened. A dot occurs after a pitch or a rest, and it increases its duration by half. For example, if a quarter note is equivalent in duration to two eighth notes, a dotted quarter note would be equivalent to three eighth notes. Generally, undotted notes divide into two notes; dotted notes divide into three. Thus, undotted notes are typically used to represent the beat level in simple meter, while dotted notes are used to represent the beat in compound meter.

Multiple dots can be added to a duration. Subsequent dots add half the duration of the previous dot. For example, a quarter note with two dots would be equivalent in duration to a quarter, eighth, and sixteenth note.

A tie lengthens a duration by connecting two adjacent identical pitches. Ties are used to either sustain a pitch beyond the length of a single measure, or to make a particular rhythmic grouping in a measure more clear.

In the example below, the duration of the first pitch is longer than a single measure, so it is represented by tying the dotted half note, which lasts the full measure, to the first beat of the subsequent measure.

Meters

Meter involves the way multiple pulse layers work together to organize music in time. Standard meters in Western music can be classified into simple meters and compound meters, as well as duple, triple, and quadruple meters.

Duple, triple, and quadruple classifications result from the relationship between the counting pulse and the pulses that are slower than the counting pulse. In other words, it is a question of grouping: how many beats occur in each bar. If counting-pulse beats group into twos, we have duple meter; groups of three, triple meter; groups of four, quadruple meter. Conducting patterns are determined based on these classifications.

Simple and compound classifications result from the relationship between the counting pulse and the pulses that are faster than the counting pulse. In other words, it is a question of division: does each beat divide into two equal parts, or three equal parts. Meters that divide the beat into two equal parts are simple meters.

There are three types of standard simple meters in Western music:

• simple duple (beats group into two, divide into two)
• simple triple (beats group into three, divide into two)
• simple quadruple (beats group into four, divide into two)

In a time signature, the top number (and the top number only!) describes the type of meter. Following are the top numbers that always correspond to each type of meter:

• simple duple: 2
• simple triple: 3
• simple quadruple: 4

Notating meter

In simple meters, the bottom number of the time signature corresponds to the type of note corresponding to a single beat. If a simple meter is notated such that each quarter note corresponds to a beat, the bottom number of the time signature is 4. If a simple meter is notated such that each half note corresponds to a beat, the bottom number of the time signature is 2. If a simple meter is notated such that each eighth note corresponds to a beat, the bottom number of the time signature is 8. And so on.

Beaming

It’s important to remember that notation is intended to be read by performers. You should always strive to make your notation as easy to interpret as possible. Part of this includes grouping the rhythms such that they convey the beat unit and the beat division. Beams are used to group any notes at the beat division level or shorter that fall within the same beat.

In this example, the eighth notes are not grouped with beams, making it difficult to interpret the triple meter.

If we re-notate the above example so that the notes that fall within the same beat are grouped together with a beam, it makes the music much easier to read.

Borrowed divisions

Typically, a meter is defined by the presence of a consistent beat division: division by two in simple meter, and by three in compound meter. Occasionally, composers will use a triple division of the beat in a simple meter, or a duple division of the beat in a compound meter.

Triplets are borrowed from compound meter, and may occur at both the beat division and subdivision levels, as seen below.

Likewise, duplets can be imported from simple meter into a compound meter.
