Chelys 7 (1977), article5
b. On the leading note, submediant and mediant. (Campion C4r, Simpson
D. V. p.19, Compendium p.31-2, Locke rule 2, Mace p.225, Purcell
p.129). Mace excludes the submediant and Purcell excludes the
submediant and mediant.
3. 6/3 chords may be played in the following progressions:-
a. When the bass falls a 3rd then rises a 2nd or rises a 3rd then falls a
2nd. Alternate it with 5/3 chords. (Coprario f. 9v only on minims and
crochets, Locke rule 7, Mace p.229, North p.90).
b. When the base rises or falls by step. (Coprario f.10v, Simpson D.V.
p.15, Locke rule 6, Mace p.228).
4. 6/3 chords are more likely:-
a. In a sharp [major] key. (Simpson, Compendium p.31)
b. In few rather than in many parts. (Simpson D.V. p.20, Compendium
p.33)
5. Do not begin or end with a 6/3 chord (Morley p.225, Butler p.49,
Simpson Compendium p.25, Mace p.225) nor make a full close with
one. (Butler p.49, Mace p.225-6).
6. In compositions of three or more parts a 3rd to the bass should never be
omitted. (Morley p.226-7, Simpson D.V. p.19)
7. Normally the 6th and 5th should not be played together, (Morley p.243,
Simpson D.V. p.19, Locke rule 5) except :
a. at a close, the 5th prepared. (Morley p.243, Simpson Compendium
p.31).
b. the dim. 5th requires the 6th to be added. (Simpson D.V. p.22-3,
Compendium p.31, Purcell p.129)
c. on a bass note preceding a bass note one tone higher on which there
will be a common chord. (North p.76-77, 81)
8. The 4-3 suspension is most usual at a final close with a cadence. (Morley
p.223, Coprario f4r, Campion D2v, Butler p.65 and 67, Simpson D.V.
p.19, 22, Compendium p.26, Locke rule 3, Mace p.227, North p.80-1,
Purcell p.94).
9. The 7-6 suspension may occur at a close with a cadence. (Butler p.65,
Simpson D.V. p.22, Compendium p.27, 32, Locke rule 4, Mace p.227,
North p.82-3).
10. Discords may be introduced as chains of suspensions, the 4th resolves
to the 3rd, the 9th to the 8ve, the 7th to the 6th, the dim. 5th to the 3rd.
(Coprario f3r, Butler p.65-6 and 68, Simpson D.V. p. 21. Compendium
p.44, Locke rules 5 and 6, Mace p.227, North p.78-9). But the music
must be slow enough for the resolutions to take effect. (Mace p.227,
North p.79, 87, Purcell p.92-7). Purcell says that the dim. 5th is the only
discord which needs no preparation, p.130.
