Comparing pitch class distributions with predefined key
profiles has become the preferred method for key-finding
in tonal music, since it was first proposed by Krumhansl
and Schmuckler in 1990 .
When determining keys using this strategy, information
about the temporal order of the notes is not taken into
account, although this might contribute additional information
useful for key-finding.
An obvious extension of the pitch class profiles is to
look at distributions of intervals – calculate scale degree
transition profiles. This idea has not been given much attention
in previous research. We conduct a data driven
experiment where pitch class profiles and interval profiles
are learned from key-annotated music and evaluated on a
