Lecture 4 - Rhythm


4.1

The Rhythm of speech

Tell me what you want, what you really really want (Spice Girls - "Wanabee")
sock-it-to-me, sock-it-to-me, sock-it-to-me, sock-it-to-me
(Aretha Franklin's backup singers on "Respect")
Yeah, That's the Ticket (Jon Lovitz's "liar" character from "Saturday Night Live")

Can you hear any of these phrases in your mind? I'm hoping that at least one of them is familiar to you. Each of them has a certain rhythm to it. The first two are from popular songs and the rhythm can be notated using standard notation. The third phrase from above isn't from a song, yet it needs a specific rhythmic delivery in order to be effective. Those of you who were watching Saturday Night Live during Jon Lovitz's run on the show know how the "Yeah, That's the Ticket" phrase should go.

All together now: " Yeaaaahhhhh, that's the ticket!"

Say these phrases aloud. Listen to the rhythm of the words

If I was to tell you the city I live in, I would say "I live in Santa Clara". Say it out loud.. Again. . . Say it over and over several times until it becomes a repetitive rhythmic phrase. These rhythmic patterns in speech can be used to help understand rhythmic notation. We will revisit some of these phrases later on in this lecture.

Note Values in standard notation

In order to incorporate rhythm into the notation system we must change the look of the note on the page to reflect its duration. Until now, the notes possessed only a notehead. There are more elements to the rhythmic portion of the notation system. Some notes have addtional attachments called stems, dots, flags and/or beams. This new stuff tells us the duration of the note (we already know the pitch of the note). Take a look at the different elements shown below.

Parts of the Note

Not all notes have these attachments, some are just the way we've been using them in the first few chapters. You will notice that we have been using "whole notes" in most of our examples. Here is a list of several more note values.

Names of the note values

The notes are related to one another with regard to duration. Notice that the names of the notes tell us the proportional relationship with regard to the whole note. A half note is half the duration of a whole note. It takes four quarter notes in a row to last the time that a single whole note lasts. Do you see how this works? All of the different note durations are related to the others in some set proportion. The eighth note is twice the duration of a sixteenth note but only half as long as a quarter note. Notice that note values are relational and not tied to any set length of time. In other words a quarter note is not required to have any specific length of time. However once you decide on the duration of a quarter note, an eighth note will always be half of that duration. A half note will be twice the duration of the quarter note. Here are a couple of short examples.

Here's the beginning of the tune 'Jingle Bells'.

Two measures of Jingle Bells

How about this Rock Anthem by the group Queen.
Two measure of 'We Will Rock You'

More Note Values

Each note value can be modified by adding a dot after the note. The dot adds 50% more duration to that note. As an example, since a half note has the duration of two quarter notes, a DOTTED half note has the duration of three quarter notes. The dot is very useful in expanding the rhythmic possibilities of our notation system.

Dotted Note Values

Although it is not nearly as common as a (single) dotted note value, a second dot can be added to a note, that second dot will add 25% of the original (undotted) value to the note. With 2 dots a note will increase its duration by 75%.

Each note value has a corresponding "rest" which is the music notation for a duration of silence.

Notation of Rests

 

The dot (and double dots) can also be used with rests. The dot has the same effect with rests as with notes; it lengthens the duration of the silence.

With these different note values and rests we can create countless different rhythms. By stringing together several different note values and rests we can notate the rhythmic element of music.

However, in order to help make all of this a little easier to read there is another part to rhythmic notation. It is called "Meter", and it is used to further organize rhythms in music. We use a "Time Signature" to indicate the meter. A time signature consists of two numbers, one above the other. The top number indicates the amount of counts in one measure. The bottom number indicates the type of note value that will receive one count. Vertical lines, called barlines, are drawn in the music to separate the note values into measures.

Example of 3/8 meter

Example of 2/2 meter

Example of 4/4 meter

4.2

METER

Most music is set within a rhythmic framework. We refer to this rhythmic framework as the Meter of a piece of music. The concept of meter allows us to organize the rhythmic element of music. Music can be subcatagorized with regard to its meter. For instance a Waltz is a 3 beat meter, most Marches are a 2 beat meter, and much of Rock & Roll is in a 4 beat meter. When you listen to music you can usually hear a steady pulse that might not necessarily be played explicitly, but it is definitely perceptable. Maybe you tap your foot, or bob your head to that pulse. Dancers react to the pulse with their moves.

4.3

Simple Meter

Not only is there a pulse to most music, there are notes of a variety of durations, short notes, long notes, etc. If we subdivide the pulse into two equal parts we are, by definition, in a simple meter. It doesn't matter how many counts are in the meter, if the pulse is divided into two equal parts to create faster rhythms then it is a simple meter. It isn't necessarily a simple rhythm, quite the contrary, a simple meter can be used to create very complicated rhythms. The term 'simple meter' refers to the two part subdivision and it is in contrast to compound meter discussed below.

Here are a few simple meters:

If the eighth note is the beat then the sixteenth note will be a 2-part subdivision of the beat.

Two part subdivision of eighth note is a sixteenth note

 

If the quarter note is the beat then the eighth note will be a 2-part subdivision of the beat.

Two part subdivision of quarter note is an eighth note

 

If the half note is the beat then the quarter note will be a 2-part subdivision of the beat.

Two part subdivision of half note is a quarter note

4.4

Compound meter

Often the pulse is subdivided into three parts instead of two parts. When this three part subdivision occurs, it creates a rhythmic feel we refer to as Compound Meter. Many popular songs use a compound meter. Here are just a few songs in compound meter that you might recognize: Three Blind Mice, Row, Row, Row Your Boat, Tarantella, Blueberry Hill (Fats Domino), Heartbreak Hotel (Elvis), Color My World (Chicago), You've Got To Hide Your Love Away (Beatles), Everybody Wants to Rule the World (Tears for Fears) and Minute by Minute (Doobie Brothers). Compound meter has a distinctively different rhythmic feel than Simple meter. A song could be arranged in either meter. An example is the song "I Can't Help Falling in Love". Elvis' version of "I Can't Help Falling in Love" is in compound meter whereas the UB40 remake of that song is in a simple meter. If you are familiar with those two versions you can hear the contrast in the rhythm.

In a compound meter, a dotted note is used for the pulse and then the next faster note value becomes the three part subdivision.

The following meters use the dotted eighth note as the beat and the sixteenth note as the 3-part subdivision.

The following meters use the dotted quarter note as the beat and the eighth note as the 3-part subdivision.

4.5

Mixing Simple, Compound

Sometimes a musical idea will use both simple and compound meter concepts. Regardless of the meter you are writing in, you can notate both simple and compound meter "feels". While writing in simple meter such as 3/4 you can always get the compound feeling (three part subdivision to the beat) by notating an eighth note 'triplet'. J.S.Bach's 'Jesu, Joy of Man's Desiring' is an example of a piece written in a simple meter, yet it has a three part subdivision throughout. An eighth note triplet is used to create the compound style subdivision.

Jesu,Joy of Man's Desiring

If you are in a compound meter such as 6/8, you can create a two part subdivision by notating a doublet.

4.6

Performance style.

Often certain styles of music are rhythmically modified during performance. If you hand a piece of music in simple meter (containing eighth notes) to a group of classically trained violinists and ask each of them to play it, you will probably hear a noticeable difference in their interpretation but undoubtedly it will still have a simple meter 'feel'. A jazz musician performing the same piece of music might produce a dramatic difference in the rhythmic 'feel'. In swing style, the rhythmic feeling is closer to a compound meter feel with a purposeful distortion of the written notation of eighth notes. A jazz player's individual style is partly determined by how much he changes an even series of eighth notes into a series of notes of unequal duration. Additionally a jazz player will sometimes change written rhythms that are mostly on the beat to become more syncopated. I'm talking about players who are expert music readers, this is not due to ignorance.

4.7

Eartraining exercises

Although rhythm and pitch work together to create melody, it is useful to isolate the rhythmic element for eartraining purposes. Below is a list of rhythms that you should try to understand and memorize. By studying these basic rhythms you will improve your ability to read any music notation. These rhythms are found at the following links. Listen to the associated audio file as you look at the notation file.


4.8

Here's how some of the phrases from the beginning of the lecture can be notated.

Tell Me What You Want

Sock it to me

Since the next phrase is not set to a pulse, it could be interpreted differently than shown below. This is only one of several ways of notating the phrase.

That's the ticket

4.9

Repetitive Rhythms

This last example uses the last rhythm of the 4 beat simple meter rhythms (number 109 from the four beat simple meter page). This rhythmic figure plus a variation on that rhythm is used repeatedly throughout this example. The variation of the rhythm takes the original rhythm and shifts it an eighth note to the right. Both of these rhythms are frequently 'off the beat' and could be referred to as 'syncopated'. These rhythms (played in the keyboard and bass parts) are set against an 'on the beat' drum part. The use of the variation rhythm occurs only near the end (before the final string line). The basic syncopated rhythms are shown below

The Required Tests - An explanation

Below are some samples from the tests for this week. These ARE NOT the actual tests but instead a short example from the tests so that you can get an explanation of how to take them and the "look and feel". The real tests have each question listed one at a time but the process is similar. To take the real tests go to the Quizzes area.

Test 5 - Note Values


Below are several time signatures followed by a single note value or rest. Determine the number of counts that note value or rest will received within the context of the given time signature. Use the answer menu (currently set to "select") to select the correct answer.

How it works

The test requires you analyze the BOTTOM number of the time signature. The top number is irrelevant. The bottom number will tell you the type of note that received ONE count. Use the note value relationships (a half note is half the duration of a whole note, etc.) and the type of note receiving one count to determine the duration of the note value shown. In the first example the bottom number is a "4". That means that a quarter note receives ONE count. The note shown is an eighth note (which always is half the duration of a quarter note). Since a quarter note receives one count in this time signature, in 3/4 an eighth note will receive a half of a count.

In the second example the bottom number is a "2". In time signatures with a number 2 on the bottom the half note receive ONE count. The shown note is a half note. In 2/2 a half note receives one count.

In the third example the bottom number is a "8". An eighth note is the duration that receives ONE count. The duration shown is a quarter note (which always received twice the duration of an eighth note). Since an eighth note receives one count in this time signature, in 3/8 a quarter note will receive two counts. (The third menu is set to the correct answer)

There is potential confusion because of the terminology. We have a quarter note but it can receive severals different amounts of counts depending on the bottom number of the time signature. (one count, one half of a count, or two counts, respectively in the three examples shown below.)

Test 6 - Meter


Below are several time signatures followed by one measure. Examine the measure to determine if it is a complete measure within the context of the given time signature. Use the answer menu (currently set to "select") to select the correct answer.

How it works

In this test both the TOP and BOTTOM numbers are relevant. First use the bottom number to determine what type of note value receives ONE count. Next add up the total number of counts within the measure. Finally compare that total with the top number of the time signature. In the 1st example shown below the bottom number of the time signature is a "4" (a quarter note receives ONE count). Adding up the two eighth notes and 2 quarter notes yields a total of 3 counts, the same as the top number. Bingo, the measure is correct.

The 2nd example shown also has a "4" as the bottom number (a quarter note receives ONE count). Adding up the half note , quarter note and eighth note yields a total of 3 and a half counts, less than the top number of "4". The correct answer is "Not enough counts".

The 3rd example shown also has a "2" as the bottom number (a half note receives ONE count). Adding up the quarter note and two half note, yields a total of 2 and a half counts, more than the top number of "2". The correct answer is "Too many counts". The third menu is set to the correct answer.
