Two studies are reported that examine the relationship between
musical mode and tempo in Western classical music. In the first study, modes were
determined for 331 works bearing the tempo markings largo, adagio, allegro, or
presto. Slower tempo markings are significantly more likely to be associated with
the minor mode in the case of music from the Baroque and Classical periods,
whereas the reverse trend is observed in music from the Romantic period. In the
second study, an analysis of 21 audio recordings of theme-and-variation keyboard
movements (from all three style periods) shows that variations written in the minor
mode are performed more slowly than neighboring variations in the major mode.
These tempo-related observations are largely consistent with research in speech
prosody, which has shown that sad speakers speak relatively slowly
