We describe an interactive analyzer for the generative theory of tonal music (GTTM). Generally, a piece of music has more than one interpretation, and dealing with such ambiguity is one of the major problems when constructing a music analysis system. To solve this problem, we propose an interactive GTTM analyzer, called an automatic time-span tree analyzer (ATTA), with a GTTM manual editor. The ATTA has adjustable parameters that enable the analyzer to generate multiple analysis results. As the ATTA cannot output all the analysis results that correspond to all the interpretations of a piece of music, we designed a GTTM manual editor, which generates all the analysis results. Experimental results showed that our interactive GTTM analyzer outperformed the GTTM manual editor without an ATTA. Since we hope to contribute to the research of music analysis, we publicize our interactive GTTM analyzer and a dataset of three hundred pairs of a score and analysis results by musicologist on our website http://music.iit.tsukuba.ac.jp/hamanaka/gttm.htm, which is the largest database of analyzed results from the GTTM to date.
