This seems an excellent opportunity to -
      1. practice and digest this new coding ofChord Pattern Numbers,
           by transforming them intoChord Symbols, and
      2. develop what is generally called Keyboard Harmony,
           by performing the Chord Symbols directly at the keyboard.
      All exercises are in theDiatonic Major Mode.




Chord Symbols

Motrix Positions
Before attacking the exercises, it might be wise to consider
      how we will dispose tetrads and triads,
           in other words, where do we include aMOTRIXin the chord symbol,
                and where do we leave it out, there being a substitution in that spot.
      At all levels,MOTRIXs will, in principle, be placed on the Off-beat of each cell.
           In 2-cell Chord Patterns (with 2 Identification Numbers),
                atLevel 0,MOTRIXs are placed on Chord Symbols 1 and 3, but
                atLevel +1,MOTRIXs are placed on Chord Symbols 2 and 3.
                     Example - the answer for "34in C".
                          could be C6 / G G7 // C (atLevel 0) or C \ G7 G7 / C (atLevel +1).
           In 4-cell Chord Patterns (with 4 Identification Numbers),
                atLevel 0,MOTRIXs are placed on Chord Symbols 1, 3, 5, and 7,
                     theMOTRIXat Chord Symbol 1 (possibly Chord Symbols 5, or even 3)
                          would be left out when we remain on the same chord,
                atLevel +1,MOTRIXs are placed on Chord Symbols 2, 3, 6, and 7, but
                atLevel +2,MOTRIXs are placed on Chords Symbols 4, 5, 6, and 7.

Find the Chord Symbols for the following Chord Patterns in the given key,
      there will be 2 Chord Symbols for each Chord Pattern Number,
           one for the Off-beat and one for the Beat of eachcell.
      1.34in G, 4 Chord Symbols,MOTRIXs atLevel 0orLevel +1
     2.5324in F, 8 Chord Symbols,MOTRIXs atLevel 0,Level +1, orLevel +2
          NOMOTRIXatLevel 0on Chord Symbols 1 and 5
      3.74in D, 4 Chord Symbols,MOTRIXs atLevel 0orLevel +1
     4.5764in G
           NOMOTRIXatLevel 0on Chord Symbol 1
      5.54in Bb, 4 Chord Symbols,MOTRIXs atLevel 0orLevel +1
     6.5574in F
           NOMOTRIXatLevel 0on Chord Symbols 1 and 3

Keyboard Harmony

For each of the preceding 6 exercises,
      using Voice-leading C,
      performing -
           the Fundamental Bass wth the left hand and
           the 4 orbit-lines, in closed disposition, with the right hand
                (in the center of the Keyboard, around "Middle C"),
      1. play each Chord Symbol only once, as aWhole note, then, keeping the same tempo,
      2. play each Chord Symbol twice (asHalf note), then, always in the same tempo,
      3. play only the left hand on the firstHalf noteand only the right hand on the secondHalf note, then,
      4. play each Chord Symbol 4 times (asQuarter note), then,
      5. play only left hand, right hand, left hand, right hand (on eachQuarter note).
           A rudimentary introduction to marching "Oom-cha" accompaniment (in steps 3 and 5),
                but playing both hands together (in steps 1, 2, and 4) can also be very useful.
      NOTE - Chord Symbol Exercises 3 and 6 (with the74Chord Pattern),
           will end lower than they started (one-and-a-half diatonic steps to be precise),
                on account of the 3 consecutive flattening progressions in the74Chord Pattern.
           Remember to start the right hand high enough so as not to end too low.
                The other exercises should end in the same disposition as they started.
