Abstract In this paper we present a salience function for melody and
bass line estimation based on chroma features. The salience
function is constructed by adapting the Harmonic Pitch Class
Profile (HPCP) and used to extract a mid-level representation
of melodies and bass lines which uses pitch classes
rather than absolute frequencies. We show that our salience
function has comparable performance to alternative state of
the art approaches, suggesting it could be successfully used
as a first stage in a complete melody and bass line estimation
system.
