| The additional part now necessary is obtained by doubling one of the three notes of the triad or chord of the sixth, these being the only chords used. The context will generally decide what note should be doubled, it being well to avoid doubling the major third to the root, more especially when it is a leading-tone ((The //occasional// doubling of the major third is by no means objected to - on the contrary, the Author, following the examples of Fux, Albrechtsberger, Cherubini, etc., does not hesitate to employ this combination to gain a smooth progression, or to escape one that is advisable. The doubled leading-tone is by far the most objectionable.)). Two of the counterpoints will thus be in noes of equal value with the //cantus firmus//; the other will consist exclusively of one of the species now under consideration, //i.e.// of semibreves ((whole notes)), minims ((half notes)), or crotchets ((quarter notes)). | The additional part now necessary is obtained by doubling one of the three notes of the triad or chord of the sixth, these being the only chords used.

| When possible, the first measure should contain a complete chord, but this will depend upon the necessary progression to the second measure. All the parts //may// commence in octave or unison (see Ex. 101). | When possible, the first bar should contain a complete chord, but this will depend upon the necessary progression to the second bar.

| Although the rules given for the various species of counterpoint of which we have already treated remain in force, they are observed much less rigidly as the parts increase in number. The relaxation of the rules as to hidden consecutives ((parallels)) mentioned in the rule just above Ex. 66 in [[bridges_counterpoint:first_species_in_three_parts|Chapter 6]] ((The presence of a third part causes the rules respecting hidden consecutives to be less stringent, particularly as regards the inner and one of the extreme parts, between which similar motion to the fifth or octave is frequently necessary to secure a smooth and, in other respects, correct progression. The upper part of the two in question should, if possible, move conjunctly, the third part being either stationary or moving by contrary motion.)). will be found useful and necessary. | Although the rules given for the various species of counterpoint of which we have already treated remain in force, they are observed much less rigidly as the parts increase in number.

| The nature and position of the //cantus firmus// in Ex. 100 involves a wide distribution of parts, not altogether advisable. The melody is, however, smooth, and moves in effective contrary motion with the //cantus firmus//. The last measure might, perhaps, with advantage, follow the ancient models, and have no third ((see the notes in parenthesis)). | The nature and position of the //cantus firmus// in Ex. 100 involves a wide distribution of parts, not altogether advisable.
