Abstract: Embodiments of the invention are related to a computer-implemented method that includes receiving musical data, identifying a succession of accentuated events in the musical data, determining a pattern in the succession of accentuated events, comparing the pattern to a plurality of reference patterns, and determining a match for the pattern using the plurality of reference patterns. The method further includes selecting one of the matching reference patterns, and generating a rhythmic musical accompaniment for the musical data based on the selected matching reference pattern. In some cases, the musical data is MIDI data or analog audio data. Analog audio data analysis includes detecting transients in the analog audio data by identifying the succession of accentuated event in the musical data. This may include identifying a plurality of events in the musical data, and determining whether each of the plurality of events is an accent.

Abstract translation: 本发明的实施例涉及一种计算机实现的方法，其包括接收音乐数据，识别音乐数据中的一连串突出事件，确定连续的加重事件中的模式，将模式与多个参考模式进行比较，以及 使用所述多个参考图案确定所述图案的匹配。 该方法还包括选择匹配参考图案中的一个，并且基于所选择的匹配参考图案为音乐数据生成节奏音乐伴奏。 在某些情况下，音乐数据是MIDI数据或模拟音频数据。 模拟音频数据分析包括通过识别音乐数据中的加重事件的继承来检测模拟音频数据中的瞬变。 这可以包括识别音乐数据中的多个事件，以及确定多个事件中的每一个是否是重音。

Abstract: Embodiments of the invention include storing musical elements in a database and processing performance data, where the musical elements including a plurality of reference accent pattern data and a plurality of reference system pattern data. Processing performance data can include receiving input data corresponding to a musical performance, determining an accent pattern for the musical performance, matching the accent pattern data to one or more reference accent pattern data in the database, and selecting one of the matching reference accent patterns. Processing performance data further includes receiving input corresponding to a selection of a musical style, one or more musical performance parameters, and generating a musical accompaniment based on the processed performance data, the selected musical style, and the selected one or more musical performance.
