Query: Automatic Determination of Chord Roots   Even though chord roots constitute a fundamental concept in music theory,
existing models do not explain and determine them to full satisfaction. We
present a new method which takes sequential context into account to resolve
ambiguities and detect nonharmonic tones. We extract features from chord pairs
and use a decision tree to determine chord roots. This leads to a quantitative
improvement in correctness of the predicted roots in comparison to other
models. All this raises the question how much harmonic and nonharmonic tones
actually contribute to the perception of chord roots.
