摘要: Tonal harmony analysis is a sophisticated task. It combines general knowledge with contextual cues, and it concerned faceted evolving objects such as musical language, execution style taste. We present Breve, system for performing particular kind of analysis, chord recognition: music encoded sequence sounding events the should assing appropriate label to each event. The solution proposed problem relies on conditional model, where domain in form Boolean features. Breve exploits recently algorithm CarpeDiem obtain significant computational gains solving optimization underlying classification process. implemented has been validated corpus chorales from J.S. Bach: we report discuss learnt weights, point out committed errors, elaborate correlation between errors growth times places less clearly asserted.
