Explanation
The music corresponding to query B306 is monophonic and the melody extraction method \(\mathcal{C}_{\mathrm{BG1}}^{\mathrm{\ast}}\) successfully tracks the fundamental frequency of the theme. As a result, this representation achieves a low separation indicator of \(\rho=0.195\). Rank 1 is also achieved by omitting the melody extraction step (\(\mathcal{C}_{\mathrm{BG1}}\)), but the separation indicator is not as good (\(\rho=0.452\)).
In contrast, the music corresponding to query B378 is polyphonic and the melody extraction step fails to track the fundamental frequency of the theme. Accordingly, \(\mathcal{C}_{\mathrm{BG1}}^{\mathrm{\ast}}\) achieves a bad rank of 128 (\(\rho=1.615\)). Omitting the melody extraction step (\(\mathcal{C}_{\mathrm{BG1}}\)) leads to rank 1 for this query (\(\rho=0.760\)).
