7 Additional Composer and Metrics
Later, a fourth composer, Lowell Mason, was added as were three more metrics with similar-
ities to the five metrics that had performed the best so far. The new metrics were introduced
to see if they could rival those five metrics or supplement them.

7.1 Lowell Mason
Before introducing the three new metrics, it was intriguing to see if the five metrics from
before continued to dominate the other 14 metrics when Mason was added. Covering all 7 of
the newly possible composer combinations (BM, DM, SM, BDM, BSM, DSM, and BDSM), 140
additional trials were run (20 per combination) for the original 19 metrics and again for the
5-metric subset.
