Tans'ur's Performance directions (Introduction to Book 2):
Ingenious Practitioners,
The Figures that are fixed over the Notes of the Basses, of all the Tunes in the several Parts of this Book, (when Vocally perform'd to Perfection,) do so augment to the Harmony, that there is no Deficiency in the Fullness thereof in such Tunes as are set in Three Parts, from those that are set in Four Parts: Which Notes may be perform'd as an Inner-Part, where an Organ is wanting; if some of the Tenor be sung as a Treble, in the Octave above, &c.
Observe, That on such Notes where nothing is figur'd, your Part may joyn with any one of the Inner-Parts, that does not make a Consecution of Perfects of one kind together from the Bass, &c.
This Part so figur'd, is most respective to the Organ, &c. which Part must be vocally perform'd with great Care and Judgment.
*** Those Figures which are set over the first and last Notes of the Upper-Parts, serve to direct the Performer both to the Pitch, and also to the Endings of all Parts of the Concert: Which Figures shews the Concords of all the Parts from the Ground, or Bass, &c. And that in Tunes of Three and Four Parts, the Inner-Parts may be omitted, and sung but in two Parts; when Voices are deficient: In the performance of which Concert a Bassoon never ought to be wanting.
