Chapter Summary: This chapter explores the uses of music with older elementary-aged children. It covers their vocal ranges, preparation for multi-part singing including echo songs, ostinato patterns, drone and multi-part performing including polyphony (multiple melodies) such as rounds, partner songs, harmony and descants, as well as other age-appropriate repertoire such as cumulative songs, play-party songs, and African-American songs.

Older children, ages 6 and up, have listened to a great deal of musical material in their short lives. The songs and sounds they’ve absorbed are part of western musical style, and are now part of the musical lingua franca or the music that is “normal” for them. They’re familiar with the musical genres, timbres, modes, and instruments, rhythmic and melodic patterns, and have learned the culturally acceptable cadences, harmonies, texture, and so forth. The lower to middle elementary-aged child is ready for more complex listening, singing, and music making. This chapter will offer music suggestions to inspire older children, including cultural games, songs, and dances.

I. Singing Voices of Older Children

Developmental Abilities

Just as children’s aptitude to learn a foreign language stabilizes after the age of 9, Music researcher Edwin Gordon (2007) found that children’s musical aptitude is also developmental, fluctuating until age 9, and stabilizing afterwards. This doesn’t mean that children can’t learn music after the age of 9, of course, but that the language of musical enculturation is well under way by that age. It is important to keep in mind that a rich musical environment at home and at school will greatly benefit a child’s musical and cognitive abilities at any age.

In terms of the voice, both boys and girls should remain singing in their head voice or falsetto. Falsetto is a light, high, head voice that is not pushed, yelled, or forced in any way. Younger boys can switch easily into falsetto or head voice, as their voices have not yet begun to change. A good falsetto produces a clear, clean “boy’s choir” type of sound, and is where children should try to sing in order to maintain a healthy voice.

Singing Ranges for Older Children

As we recall from the previous chapter, children’s singing ranges expand year by year. Older children may have an expanded vocal range, but it is important to remember that the pitches that are most comfortable to sing are in the middle of their range.

Six to Eight Years Old

Grades first through third, or six to eight-year-olds, can sing about an octave from C to C’, with their most comfortable notes from E to G.

Eight to Eleven Years Old

Children aged eight to eleven can sing from the B flat below middle C to about an E flat or E, 3 notes above high C’. Their most comfortable notes are between D and G.

Selecting a Song in the Proper Singing Range

When selecting a song for older children, first check the pitch range appropriate for the child given the guidelines above. Most of the notes of the song should match the child’s most comfortable pitches right in the middle of their range. Children start to become weaker when singing around middle C. Try to avoid songs that sit in a lower range such as middle C or D, and instead pitch or place the song slightly higher up around E, F and G. Most of the songs in this book are transposed to the key of F so that most of the pitches of the song are around the tonic, or F.

Another important thing to keep in mind is that where an adult feels most comfortable singing, is probably not where the child feels most comfortable. Remember that many times, classroom teachers pitch the song in their own range, not thinking about where the song would work best for the children, and children struggle to sing well.

II. Advanced Musical Experiences

Beginning at around eight years of age, children are ready for more advanced musical experiences vocally, instrumentally, and theoretically, and more complex musical subject matter. This section will explore different types of songs appropriate for older children, and the process for introducing more complex musical experiences.

Repertoire

Most of us are surrounded by pop music culture, and children at this age are particularly aware of and influenced by the pop scene. They hear pop music, watch singing competition shows on television, have pop idols, and want to sing pop music. The challenge with older children is their desire to vocally imitate the pop singing style. This music, of course, is very familiar and accessible to them, and it is only normal that they are inspired by and want to mimic their favorite pop star. However, keep in mind that a child’s vocal apparatus is still developing, and imitating adult singing with scoops, chest voice, or belting is affected singing and not natural. Not only does it inhibit the child’s sense of ownership of their own vocal instrument and musicality, it also inhibits their ability to explore the natural timbre of their own voices, and find their own unique musical style. These songs are intended for adult voices, and are often out of the comfortable singing range of children. Belting or pushing a developing voice too far can be detrimental to the child’s voice, and can result in permanent damage.

Subject Matter

Luckily, there is an enormous children’s repertoire of songs, including folk songs, historical songs, play party songs, story and game songs, classical pieces, and popular songs written for children’s voices with subject matters that appeal to their developing sense of morality and worldview, and are steeped with sociohistorical meaning.

Many songs for older elementary children are highly appropriate for use in the classroom curriculum, including core subject songs (math, social studies, science), national songs, cultural and historical songs, language arts songs, holiday songs, etc. The songs presented in this book are folk and popular songs, some of which are not only historically important, but culturally significant as well. These songs are part of a potentially rich musical experience for the child—exposing them to material with inherent sociocultural meaning that can contribute to excellent lessons and, most importantly, enhance integration activities.

Multiple Part Performance: Introducing Texture and Layers

By the age of seven or eight, children are ready for some type of vocal multiple part performing. Multi-part performing includes both instrumental and vocal music making, and can refer to the performance of more than one melody at the same time (i.e. a round), vocal harmony, or any type of accompaniment. Playing two or more parts on instruments is far easier and children can begin this type of multi-part performance much earlier. Vocally, however, children find it quite difficult to sustain their own vocal part against that of another singer or singers before the age of 8.

Multi-part performance in either the vocal or instrumental milieu is cognitively beneficial, and will increase a child’s musical competence. Older children appreciate and are capable of singing complex songs, particularly those that include multiple parts and simple harmony. Musical texture (performing multiple lines of music simultaneously) not only creates more intricate and interesting music, but it provides significant cognitive benefits. Multi-part performance of any kind requires the child to focus intensely on their part, training the brain to produce one part while acknowledging additional auditory stimuli coming from the other parts. The brain then must process the whole piece at once while still remaining focused on the one performing part.

Children, who may not yet ready for harmony, can be prepped for harmony at much earlier ages through the use of layered speech pieces, rhythmic instrumental or vocal patterns (see ostinato below). Keep in mind that children are performing in multiple parts even when they are singing a song and doing any other simultaneous activity such as tapping the beat, playing a pattern on an instrument or performing body percussion (snapping, stomping). Any rhyme can be made more complex by adding a body percussion pattern or simple instrument pattern.

Deedle Deedle Dumpling

English nursery rhyme

Any familiar song can be used to teach two parts, such as taking a simple melody and adding a vocal ostinato. The song “A Ram Sam Sam,” for example, is a traditional Moroccan folk song that contains many simple repeating patterns. Begin by learning the song and performing it in unison. Then sing several times as a two part round.

Creating ostinati patterns

Ostinati are short patterns, repeated persistently throughout a piece often at the same pitch. Ostinati (pl. of ostinato) can be either vocal or rhythmic. The easiest way to find an ostinato is to take a short pattern right from the song itself. Ostinati can also be composed. Using short patterns from the song is a simple way to create vocal or rhythmic ostinati. Start by finding a short, simple, fun or interesting pattern in the song. An ostinato can be performed using body percussion, instruments or with the voice.

If the children are not ready to sing the song with a sung vocal ostinato, begin by chanting the song as a speech piece and adding one or more speech ostinato patterns.

A Ram Sam Sam (Speech with one ostinato)

Begin with a simple ostinato. In this case, the rhythm of the very last phrase “Ram Sam Sam” (ta ta ta rest), works very well. Have children clap and say the words simultaneously.

Two additional ostinati for this song with more complex rhythms include “ra-fiq a ra-fiq” (“ta-a ta, ta ta-a ta”) or “gu-li gu-li gu-li gu-li” (ti ti ti ti ti ti ti ti). Have children clap and say their ostinati. Notice, however, that “a ra-fiq” begins on a pickup beat, which can be tricky for entrances. To avoid that, begin with “ra” on the downbeat so that both ostinati (ra-fiq and gu-li gu-li) begin in simultaneously.

Divide the class into four equal parts, one group chanting and clapping the “melody” rhythm and the other three chanting and clapping the ostinati. After a few times through, have the students drop the chanting and perform the piece using clapping only.

A Ram Sam Sam (Speech with vocal ostinato)

Depending on the level of the class, the switch to singing the song with all of its ostinati can be done all at once or by using a combination of spoken and sung. Using a combined approach, begin by having the melody group sing the melody, while the ostinati groups come in one at a time using speech only.

A Ram Sam Sam (With one ostinato)

Gradually add the other two ostinati patterns, one at a time.

A Ram Sam Sam (With two ostinati)

A Ram Sam Sam (With three ostinati)

Move from using rhythmic ostinati to melodic ones. Be sure to have them learn the song very well before adding a sung ostinato. Divide the group in half and have half sing “Ram Sam Sam” while the other half sings the melody. These are examples of pitched ostinati that are taken directly from the melody of song (measures 2 and 9). The easier of the two is 1a, but if the class is advanced, use 1b.

The other two ostinati can also be sung. For more advanced groups, try dividing into three parts, with the melody in one part and sung ostinati in the other groups.

Vocal Ostinato #2

Vocal Ostinato #3

A Ram Sam Sam (With three sung ostinati)

Note: In order for the harmony to work with the song, the pitches for “gu-li gu-li” need to be changed in measures 3 and 7 to a “Bb” rather than “A.” If this is too difficult, remain on the “A.”

Drone

A drone is usually a single pitch, usually held or repeated underneath a melody. The simplest type of accompaniment is to add a single note drone to a melody. Songs such as “Amazing Grace,” “Bow, Wow, Wow,” “Tideo,” are all pentatonic songs that work well with a drone accompaniment. Drones can also be several pitches, but they repeat throughout all or most of a song. Children may be tempted to speak or chant the drone part, but it is important that they sing it, maintaining a constant pitch and good tone.

Tideo

Traditional American play party song

More complex part singing

Older children are ready for singing in two, three and four parts, and also performing on instruments layering many different patterns together. In singing, there are two types of basic part-singing appropriate for children: polyphony and harmony.

Polyphony is a word that refers to multiple independent lines of music sung at the same time. Polyphony can happen in many different ways. Rounds and partner songs are two good examples of polyphony.

In a round, all of the voices are singing the same melody but at slightly different times, and in a partner song each part is singing a different melody. The important element is that all of the parts or “voices” are equal, and there isn’t a single dominant melodic line. Although we associate rounds with children, there are many complex and lengthy rounds with more serious topics for adults.

Rounds

Rounds or canons have been around for hundreds of years, and play a significant role in European and American society. Group singing played a major role in society, for emotional expression, entertainment, social cohesion, and so forth. In a round, everyone contributes equally in terms of melody. The oldest polyphonic song known is the Medieval English song “Sumer Is Icumen In” dated from the mid-13th century. This round, which is about the arrival of summer, actually has two “melodic ostinati,” which are known as “grounds,” at the end, which can be sung along with the melody.

Sumer Is Icumin In

Medieval English song, 13th century

More simple rounds that most people know include: “Row, Row, Row Your Boat,” “Frère Jacques,” and “Scotland’s Burning.”

Row, Row, Row Your Boat

American folk song and round, 1852

Frère Jacques

French folk round, 18th century

Scotland’s Burning

Traditional American round, 19th century

More complex rounds include: “Oh How Lovely Is the Evening,” “Dona Nobis Pacem,” “Hey, Ho, Nobody Home,” which is in minor, and “Viva la Musica,” a 16th century round written by the Renaissance composer Giovanni Palestrina.

Oh, How Lovely

German folk round

Dona Nobis Pacem

Text from “Lamb of God,” Latin Mass

Hey Ho, Nobody Home

Viva la Musica!

Michael Praetorius (1571-1621)

Partner songs

Partner songs are another way to experience multiple-part (polyphonic) singing. In a partner song, two or more songs, which are musically compatible, are sung together. Similar to a round, everyone contributes a melody. Partner songs are slightly more challenging to sing in that they use different melodies. A good example is the song “One Bottle of Pop” in which three separate melodies work well together.

One Bottle of Pop

Below are some additional examples of individual songs and their potential “partners” that blend well and go together. The songs “This Old Man,” “Skip to My Lou,” “Shoo Fly,” “Bow Belinda,” and “Sandy Land,” for example, are all able to be sung simultaneously.

Harmony

After success singing rounds and partner songs, children may be ready to sing in harmony. Harmony is the sounding of two notes simultaneously. When singing harmony, one voice usually has the melody and is dominant, while the harmony parts take a “back seat” so to speak. The melody notes are usually the highest notes, with the harmony supporting underneath. Singing in harmony is quite a bit more challenging than partner songs or rounds.

Harmony lines are often the interval of a third (3rd) or a sixth (6th) below the melody line. Singing a 3rd or 6th away from the melody is very challenging, as the tendency is for singers to slip from their parts into unison with the melody.

Preparation for vocal harmony

Singing a drone is excellent preparation for harmony (see “Tideo” above). Here is a scale warm-up that also helps prepare students to hold onto their part against another moving part.

III. American Children’s Games and Game Songs

America’s folk heritage is rich with songs from many cultures. Folk songs such as play party songs, African-American songs, story songs, and dance-songs are all a part of American music history and are excellent opportunities to discuss history and the role of music in our culture. The lyrics to these songs contain literary and social references, and are rife for inclusion in the interdisciplinary classroom. The songs can also fit into other aspects of children’s lives and their school curriculum as well.

Many game songs originated in the Georgia Sea Islands, a series of over 100 islands off the coast of South Carolina, Georgia, and Florida. The Islands have a long and complex cultural history, but are most known for their rich African-American heritage as white plantation owners left the islands in the 19th century leaving their slaves behind. The result was the creation of a distinct Gullah/Creole language and culture, which can be found in many children’s games.

Play Party Games

Play parties are singing parties that evolved along with the rural frontier American experience. In the early 1800s in the southwestern and western states, there was a prohibition against playing musical instruments and dancing by certain religious organizations. Play parties were a way around this. They were a social activity in which young people sang songs while clapping, incorporating drama, and some swinging movements. Many songs we know such were play-party songs such as “Buffalo Gals,” “Skip to my Lou,” “Old Dan Tucker,” “Old Brass Wagon,” “Pop Goes the Weasel,” “Weevily Wheat,” and “B.I.N.G.O.”

The movements to “Old Brass Wagon” have children in a circle, basically following the instructions in the song. Everyone holds hands and circles to the left on the first verse, right on the second, etc.

Old Brass Wagon

Traditional American play party song

The circle dance song “I’ve Been to Haarlem” requires a more sophisticated choreography. One child stands in the middle of a circle of partners who walk in a circle in promenade position. On the words “turn the glasses over,” the partner on the outside of the circle turns under the inside partner’s arms, thus changing direction. The partners let go, and circle in opposite directions until the words “lose your partner in the ocean.” On this last word “ocean” the child in the middle quickly rushes around trying to find a partner and leaving one child “out” who is now the one in the middle.

I’ve Been to Haarlem

The song “Weevily Wheat” refers to wheat that is infested with beetles or weevils that destroy the plants. The game for “Weevily Wheat” requires children in small groups of four, with each child numbering off 1-2-3-4. The song begins with the children holding hands and moving clockwise. On “take some,” everyone reverses direction. On the words “five times five” all stand in place and layer hands in the center of the circle to the beat of the song. Child 1 puts their left hand in, 2 put theirs on top, 3 and 4 continue the pattern. Then all layer their right hand in. When they run out of hands, the children pull their left hand out from the bottom of the pile in turn and place on top, continuing until the end of the verse. This song contains multiplication and can be used as an extension activity for math.

Weevily Wheat

Traditional American play party song

Cumulative Songs

Cumulative songs are those in which each verse adds on lyrics and music from the previous verse, and by the end of the song, the singer sings through all of the accumulated lyrics. The most well-known cumulative song is “The Twelve Days of Christmas,” but there are many others. These songs provide an excellent cognitive workout, as the singer has to mentally catalog each verse, adding each verse as they progress through the song, but then singing all of the lyrics backward in a cumulative fashion.

Some examples of cumulative songs are “Hey Ho, the Rattlin’ Bog,” “There was an Old Lady who Swallowed a Fly,” “The Green Grass Grew all Around,” “Allouette,” and “I Bought me a Cat.”

The song “Rattlin’ Bog” has a refrain with verses that accumulate. This Irish song is also meant to gradually speed up in tempo as you sing.

The Rattlin’ Bog

Traditional Irish folk song

“I Bought Me a Cat” is a traditional American song arranged by the famous American composer Aaron Copland. This song does not have a refrain, but the verses themselves accumulate lyrics.

I Bought Me a Cat

Traditional American children’s song

I bought me a pig, my pig pleased me

I fed my pig under yonder tree,

My pig says “griffey, griffey”

My hen says “shimmey shack, shimmey shack”

My goose says “quaw, quaw”

My duck says, “quaa, quaa”

My cat says “fiddle-i-fee.”

I bought me a cow, my cow pleased me

I fed my cow under yonder tree,

My cow says “baw, baw” (etc.)

I bought me a horse, my horse pleased me

I fed my horse under yonder tree,

My horse says “neigh, neigh” (etc.)

I got me a wife, my wife pleased me

I fed my wife under yonder tree,

My wife says “honey, honey” (etc.)
