Cuthbert, Anku files archive

The following files give added information for the article, Michael Scott Cuthbert, "Generalized Set Analysis of African Music: Evaluating and Expanding the Theories of Willie Anku", Journal of New Music Research 35.3 (2006), pp. 211–219.

The main files to use are adowa.score.txt which is the score file for evaluating four different transcriptions of Adowa, rtp.pl.txt which (when run without the .txt extension) processes adowa.score.txt (which is the scorefile) and one of the concise encodings of Adowa master drum lines:

• anku_conc.txt (Anku's published transcription)
• anku_diss.txt (Unpublished transcription from Anku's dissertation)
• zab_conc.txt (Kongo Zabana's transcription of Adowa)
• kam_conc.txt (David Kaminsky's transcription of Adowa)

Each of these files encodes a single pulse of Adowa as either 0 (not struck), 1 (low drum), 2 (high drum), or 3 (flam or double hit)

prime_forms.pl.txt finds Anku's prime forms given as input one of the Adowa transcriptions above. Use as:

cat anku_conc.txt | perl prime_forms.pl.txt | sort -n

Or see prime_forms_out.txt for this example

set_density.pl.txt gives (in a rotated graph) the attack density of any given set (as defined by a N-beat pattern starting on the structural time point). A refinement could be made where the attack density of the labelled sets from rtp.pl is used rather than the fixed 12-beat set.

cat anku_conc.txt | perl set_density.pl.txt

Or see set_density_out_anku.txt for results.
