摘要
Musicians interested in improvising melodies often benefit from the ability to analyze chord progressions for tonality and from possession of an understanding of a range of idiomatic chord progressions. We describe automated analysis using an approach to representing idioms known as %26quot;bricks,%26quot; which can also be used in analysis of tonality. The brick nomenclature is attributed to Conrad Cork%26apos;s %26quot;Lego Bricks%26quot; approach, as extended by John Elliott. We demonstrate a semi-automatic grammatical approach to analysis of chord sequences and sketch its implementation, which is available in the form of free, open-source software called Impro-Visor.
