In this class, the Subject will use 2 Orbit Lines at the same time.

Specifics

Form AAAA BBAA - Chord Pattern M33-44 -
Subject Orbit Lines 2-1 and 0-0 for the first cell, 1-1 and 0-0 for the second cell -
Counter-subject Orbit Line, preferably 3-2 for both cells.

         Another 16-bar fugue, with a chord at each , a half-bar at the beginning and a half-bar at the end.

The Expositions

The Fugue-lines

NOTE -
         In the Counter-subject, to produce a sonority of thirds/sixths with the Subject,
                   the choice of the 0(3) substitution in the first cell and 3 itself in the second cell.
         At the beginning of the first X, a displacement to recuperate the MEDIAN lost in the Subject,
                   then the use of the MOTRIX on the Beat of the first cell to maintain movement,
                             but not on the Beat of the second cell.
         The possible choices of the second X.
         The consecutive fifths (fourths) between the Counter-subject and the first X ;
                   despite the fact that one of these fifths is diminished,
                             a little embroidery will advantageously camouflage this small weakness.

We have here, in Line 4, a Fundamental Bass, needless to look farther.
         Line 1 should be used as Soprano, because Line 3 ends on the MEDIAN.

Transposing this in F places it in a good vocal range.
         To avoid the full close in the middle of the fugue (the AAAA), invert Soprano-Tenor and Alto-Bass.

For the ornaments, see the complete fugue below.
         Note the substitution at the beginning of the Counter-subject for the sonorities with the Subject,
                   the pick-up with Passing Tone to the first X,
                             as well as the embroidery to cover the consecutive fifths in the middle of the first X.

The Divertimento

Only one Divertimento of length BB, 8 chords (4 bars),
         ending on the TONIC to accomodate the pick-up to the first X.
Chord Pattern 71*7*4, a complete circle from TONIC to TONIC,
         with Dominantized ANTE-2.
In 2 Voices, using the beginning of the first X, inverted.

The Complete Fugue

Dispose the Expositions AAAA and AA.
Insert the Divertimento (in the Soprano and Alto voices).
Touch-ups -
         between the AAAA and the BB, the Alto drops its last note for the Pick-up to the Divertimento,
         between the BB and the AA, inevitable repeats in the words of the Soprano.



         


Here again, silly words which describe the nature of the fugue :
         for the Subject : "You can put 2 lines together"
         for the Counter-subject : "In the subject of the fugue,"
         for the first "X" : "But take care, take care, of the other parts,"
         for the second "X" : "The other parts."
