Note: The model with group accuracy, original melody, singer accuracy and singer order was not found to be significantly different than whether or not the melody simply contained a Embedded Image cadential motion. This table examines models with each effect removed, to examine any possible significant predictors. It would therefore appear that the majority of the variance in predicting whether the melody would undergo change in the cadence is accounted for by whether the melody has a Embedded Image or a Embedded Image ending.
