The different aspects of a melody
Some objects present a different aspect depending on the angle from which they are viewed. An upside-down ice cream cone looks like a triangle seen from the side, but like a circle seen from the top. The same melody may also be presented in various aspects, both in the World of Pitch (in itsMode, major or minor, diatonic or chromatic) and in the World of Time (in its Rhythm, binary, ternary, quinternary ...), which we will see here.

Transformations At Small Levels

Binary and Ternary Meters

Example
A well-known example of change of meter is the Mexican song La Cucaracha, originally conceived in 3/4 time, but which the rest of the world knows in 4/4 time with jazzysyncopations.

We will first examine the different possibilities
          of binary andternarysubdivision of thesmalllevels
     and discover the different rhythmical aspects of the same melody.

Footsies
Don’t forget the Footsies for all the following musical examples,
because understanding them is one thing,
but feeling them is the most important thing.

Choice of note values
For the sake of consistency (in totally binary rhythm),
     each Beat (and Off-Beat) ofLevel 0will always consist of theWhole note.
As we subdivide,
     each Beat (and Off-Beat) ofLevel -1will consist of theHalf note,
     each Beat (and Off-Beat) ofLevel -2will consist of theQuarter note,
     each Beat (and Off-Beat) ofLevel -3will consist of theEight note,
     each Beat (and Off-Beat) ofLevel -4will consist of theSixteenth note.
The bar-lines will always be placed atLevel -1, with bars in 4/4 (or 2/2) time.
     The bar-lines ofLevel 0will be indicated solid, the others, atLevel -1, dashed.

Let’s run through our list of 7 melodies.

1. Twinkle, Twinkle, Little Star

(a) The shortest notes of this song will be represented asHalf notes
     and bars would normally be expressed in 2/2 time.
rhy01atwinkle

(b) With only two notes in a bar (atLevel -1) it is not possible to produce ternary subdivision
     which requires another level of subdivision (Level -2, with fourQuarter notes per bar).
However it is possible to produce ternary subdivision (grouping) usingLevel 0,
     both withLevel -1, and withLevel +1,
          which we will see in the following section (TransformationsatLevel 0).

2. Polly, Put The Kettle On

(a) The shortest notes of this song will be represented asQuarter notes
     and bars would normally be expressed in 4/4 time.
rhy02apolly

(b) Discovering its aspect in 3/4 time would mean removing beat 2 from each bar.
     The logical way to do this without losing any material
          is to reduce by half all the values of beats 1 and 2
               (the first 2 notes of each 4/4 bar becomingEight notes instead ofQuarter notes
                    theHalf noteat the beginning of Bar 7 becomes aQuarter note).
Each bar in 3/4 time would be at what we callLevel -2-1
     (a ternary fusion ofLevel -2andLevel -1).
Try this for yourself- the song will take on a Mazurka flavor.

Footsies
At the smallest level (ternaryLevel -2-1), the feet startR(ight),L(eft),T(ouch).
At the next level (binaryLevel 0), the feet startLas in the original binary aspect.

(c) Discovering its aspect in 6/8 time is not possible at the small levels
     because we would need subdivision atLevel -3to have the requiredEight notes.

3. Red River Valley

(a) The shortest notes of this song will be represented asEight notes
     and bars would normally be expressed in 4/4 time.
rhy03aredriverb

There are several possibilities here.

rhy03bredriver
(b) Since a complete bar is made up of two identical parts ofQuarter noteEight noteEight note
     it is very tempting to start by discovering its aspect in 6/8 time
          byreducing by half all the values of beats 1 and 3(the first and thirdQuarter notes).
     giving the song a Waltz flavor
          with a meter quite similar to that ofMexican Hat Dance.

Footsies
At the smallest level (ternaryLevel -3-2), the feet startL-T-R.
At the next level (binaryLevel -1), the feet startR-L, with 2 notes pickup,
     as in the original binary aspect.

rhy03credriver
(c) However, nothing prevents us from discovering its aspect in 3/4 time
     by reducing by half all the values of beats 1 and 2 (the first and secondQuarter notes)
          (as we did forPolly Put The Kettle On).
     We are back to the Mazurka flavor.

Footsies
At the smallest level (binaryLevel -3), the feet startR-L, as in the original aspect.
At the next level (ternaryLevel -2-1), the feet startT-R-L.
At the next level (binaryLevel 0), the feet startL-R, with 2 notes pickup, as in the original aspect.

rhy03dredriver
(d) It is now possible to find a fourth aspect
     by maintaining exactly the same note values of the 3/4 aspect (c),
     but by performing the melody in 6/8 time, with a binaryLevel -1and a ternaryLevel -2-3,
          producing what are known as “hemioles” (3 in the time of 2).
     Without changing the note-values, the Mazurka flavor has been replaced by a more Spanish flavor.

Footsies
At the smallest level (ternaryLevel -3-2), the feet startL-T-R.
At the next level (binaryLevel -1), the feet startR-L, with 2 notes pick-up, as in the original aspect.
Don’t forget to sing the (c) 3/4 version again with a ternary footsie (T-R-L) atLevel -2-1
     to really feel the difference.

This gives us 4 different aspects of the same song.
We will also find 4 different aspects in 5.Oh Where Is My Little Dog Gone ?

4. Rock-A-Bye, Baby

(a) The shortest notes of this song will be represented asQuarter notes
     and bars would normally be expressed in 3/4 time.
rhy04arock

Footsies
At the smallest level (ternaryLevel -2-1), the feet startR-L-T,
     as we already know.

There is only one possibility of transformation here.
rhy04brock
(b) Bringing it to the fundamental, independent binary levels (Level -2andLevel -1)
     will imply doubling the note values of beat 1 of each bar of 3/4,
          theQuarter notewill become aHalf note, theHalf notewill become aHalf note.and theHalf note.will become aWhole note.
     It will give the song a March flavor (in 4/4 time, probably 2/2).

Footsies
Try beating the 2 smallest binary levels (Level -2andLevel -1) at the same time
     with the feet startingR-T-L-T, which we already saw.
Don’t forget to sing the (a) 3/4 version again with a ternary footsie (R-L-T) atLevel -2-1
     to really feel the difference, and notice that the left footThas been removed.

(c) Since there are noEight notes inLevel -3,
     the 6/8 aspect is not applicable in the small levels.

5. Oh Where Is My Little Dog Gone?

(a) The shortest notes of this song will be represented asEight notes
     and bars would normally be expressed in 6/8 time.
rhy05awhere

Footsies
At the smallest level (ternaryLevel -3-2), the feet startT-R-L.
At the next level (binaryLevel -1), the feet startR-Lwith 1 note pickup.
     as we alreadyknow.

Like song 3.Red River Valley, there are several possibilities here.
rhy05bwhere
(b) The first is to bring it from its original 6/8 meter to the fundamental 4/4 meter
     by doubling the note values of the first and fourthEight notes of each bar.
          We evidently have the March flavor.

Footsies
Try beating the 2 smallest binary levels (Level -3andLevel -2) at the same time
          with the feet startingT-R-T-L, which we alreadysaw.
     Don’t forget to sing the (a) 3/4 version again with a ternary footsie (T-R-L) atLevel -3-2
          to really feel the difference, and notice that the left footThas been removed.
At the next level (Level -1), the feet startR-Lwith 1 note pickup, as in (a).

rhy05cwhere
(c) Then we can discover its aspect in 3/4 time
     by reducing by half all the values of beats 1 and 2 (the first and secondQuarter notes)
          We have the Mazurka flavor.

Footsies
At the smallest level (binaryLevel -3), the feet startL-R.
     (There are not enoughSixteenth notes notes to warrantLevel -4)
At the next level (ternaryLevel -2-1), the feet start ,R-L-Twith 1 note pickup.
At the next level (binaryLevel 0), the feet startL-Rwith 1 note pickup
     as in the original aspect.

rhy05dwhere
(d) Now we can maintain exactly the same note values of the 3/4 aspect,
     but perform the melody in 6/8 time, with a binary footsie (R-L) atLevel -1,
          with the Spanish hemioles.

Footsies
At the smallest level (ternaryLevel -3-2), the feet startT-R-L.
At the next level (binaryLevel -1), the feet startR-Lwith 1 note pickup.
Don’t forget to sing the (c) 3/4 version again with a ternary footsie (R-L-T) atLevel -2-1
     to really feel the difference. (Don’t forget the 1-note pickup)

This melody was also used as an example in the4 Strong Modes.
With 4 aspects of modes and 4 aspects of meter,
we could have 16 aspects by crossing the modes and the meters.

6. Happy Birthday

(a) The shortest notes of this song will be represented asEight notes
     and bars would normally be expressed in 3/4 time.
rhy06abirthday

Footsies
At the smallest level (binaryLevel -3), the feet startR-L.
At the next level (ternaryLevel -2-1), the feet startT-R-L.
At the next level (binaryLevel 0), the feet startL-Rwith 2 notes pickup
     as we alreadyknow.

There is only one possibility of transformation here.
rhy06bbirthday
(b) Bringing it from its original 3/4 meter to the fundamental 4/4 meter
     by doubling the note values of beat 1 of each bar of 3/4.
          We evidently have the March flavor.

Footsies
At the smallest level (binaryLevel -3), the feet startR-Las in the original aspect.
Try beating the 2 next binary levels (Level -2andLevel -1) at the same time
     with the feet startingT-R-T-L.

(c) We cannot produce the 6/8 meter aspect in the small levels
     because we do not have a sufficient number ofEight notes.

7. Down In The Valley

(a) The shortest notes of this song will be represented asSixteenth notes
     and bars would normally be expressed in 9/16 time.
rhy07avalley

Footsies
At the smallest level (ternaryLevel -4-3), the feet startR-L-T.
At the next level (ternaryLevel -2-1), the feet startT-R-L.
     as we alreadyknow.

There is only one possibility here.
rhy07bvalley
(b) Bringing it from its original 9/16 meter to the fundamental 4/4 meter by transforming
     - each group of 3Sixteenth notes on the third beat of each bar into 1Eight noteand 2Sixteenth notes,
     - eachEight note.on the first beat of each bar into aHalf note,
     - eachEight note.on the second beat of each bar into aQuarter note.
          We evidently have the March flavor.

Footsies
All the levels being binary, the footsies are quite simple here.

(c) We cannot produce the 6/8 meter aspect
     because we do not have a sufficient number ofEight notes.

Quinternary Meters

The 5/8 bar (2+3) is considerably more sophisticated than the 3/4 or 6/8 bars
     because 3 levels are fused together intoLevel -3-2-1
          rather than 2 levels as in the previous cases -
                Level -2-1for the 3/4 bars, and
                Level -3-2for the 6/8 bars,
     and very little music is written directly in this meter.
However, it is quite simple to transform music from 6/8 to 5/8
     by removing the secondEight notefrom each 6/8 bar.
          Here again, we would have the choice of removing whatever we find on this secondEight note
               or "squeezing" the material of the first 2Eight notes down to half-size.
Let's see a few examples -

3. Red River Valley (5/8)

If we take the 6/8 version ofRed River Valley
     and remove the secondEight notefrom each 6/8 bar
rhy03eredriver
we get the Red River Limp 2 clip
     with relatively little loss if we remove the contents of the secondEight note
          so as not to interrupt the flow ofEight notes with the appearance ofSixteenth notes.

5. Where, Oh Where, Is My Little Dog Gone ? (5/8)

If we take the original 6/8 version ofWhere, Oh Where, Is My Little Dog Gone ?
     and remove the secondEight noteof each bar
rhy05ewhere
we get a 5/8 version of the song
     with relatively little loss if we remove the contents of the secondEight note.
