4.1 "Composed" Triads

[1] Our analyses used large samples of triads drawn from the chorale harmonizations of Bach and the string quartets of Haydn and Mozart. The following guidelines formed the basis of our procedures for sampling triads.

[2] In order to increase the size of our sample, we made use of computer software to automate the analysis and sampling of music. In order to turn the process over to a computer, it was necessary to operationalize some basic musical definitions, in particular:

[3] The sampling process benefited immensely from the use of existing resources, particularly electronic scores and computer analysis software. All of the scores were taken from the MuseData database created by CCARH,(71) and were analyzed using both the Humdrum Toolkit(72) and the Melisma harmonic analysis software.(73)

[4] The complete process resulted in a total sample of 2643 triads from the chorales, and 960 triads from the string quartets. Some triads taken randomly from the sample are shown in Figure 4.1a.


Figure 4.1a. Some triads taken at random from the sample:
  1. the Bach chorale "Den Vater dort oben" (BWV 292), measure 9,
  2. a Haydn string quartet, opus 74 number 3 ("The Rider"), third movement, measure 3,
  3. the Bach chorale "Wie bist du Seele in mir so gar betrübt" (BWV 435), measure 1, and
  4. a Mozart string quartet, K. 169 ("Haydn" #2), fourth movement, measure 73.
