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.
