This may present challenges for those taking their first steps into the world of partimenti--challenges that might prove insurmountable for those without experience in thoroughbass
The principal discussion of thoroughbass
, derived almost entirely from Italian sources, is found in chapter 6, `De Basso Generali seu Continuo', of volume 3 (Wolfenbuttel, 1619).(28) What Praetorius has to say about basso continuo is revealing both in terms of his conception of the technique in general and, more specifically, in terms of how it was supposed to be realized in 17th-century musical practice.
The basic compositional principle is the same as that which in the 17th century would result in the familiar thoroughbass
technique: a bass line is added to an existing treble line, thus creating an outer-voice structural duet; the two inner voices are then added, taking into account the quality of the resulting vertical sonorities, which in turn are defined by the intervals counted from the bass upwards.
The most beguiling is that by Arnold Whittall, who takes a cue from Schoenberg's Harmonielehre to propose a system of chord classification based on intervals above the bass: that is, a kind of modernized thoroughbass
. This enables him to analyse certain post-tonal pieces in a language that sounds reassuringly familiar, describing certain pitch-class sets with ad hoc names derived from traditional harmonic theory.
Baroque counterpoint was viewed from a harmonic perspective, in which figuration reduces to linear voices that represent the intervals of a triad, as evident in the practice of thoroughbass
. Spitzer offers insightful commentary on the works of Gioseffo Zarlino, Robert Fludd, Johannes Kepler, Marin Mersenne, Athanasius Kircher, Christoph Bernhard, Johann David Heinichen, Joachim Burmeister, and Johann Adolph Scheibe, among others, with musical examples from Heinrich Schutz and Johann Sebastian Bach.
It also excludes widely used teaching material such as thoroughbass
and instrumental tutors.
1665-1738), an organist and composer of some 171 known compositions, was also a publisher in Madrid of music and books on music, including the original edition of his thoroughbass
Becherini calls chiavette the clefs, other than F4, used occasionally for a few bars in a thoroughbass
staff in order to avoid ledger lines, especially when doubling a solo performed by an upper voice.
This view depends on a title page added by an eighteenth-century owner, and although the latter was a student at the Leipzig Thomas-Schule--well after the composition of these works--this hardly demonstrates that Niedt's was "Bach's favorite thoroughbass
The most notable deletion is Precepts and Principles for Playing the Thoroughbass
or Accompanying in Four Parts, which is available in Pamela Poulin's facsimile edition (New York: Oxford University Press, 1994).
Savino's observations on the execution of ornaments and the application of thoroughbass
training to guitar playing are particularly noteworthy.
In 1738 Johann Sebastian Bach apparently dictated to his student Carl August Thieme a set of rules and instructions for playing the thoroughbass
and accompanying in four parts.
