Abstract:
A chord estimation apparatus estimates a first chord from an audio signal, and estimates a second chord by inputting the estimated first chord to a trained model that has learned a chord modification tendency.

Claim (Index 12):
The chord estimation apparatus according to  claim 8 , wherein the processor is further configured to:\n execute a boundary estimation model that has learned relationships between time series of first feature amounts and pieces of boundary data, each piece of boundary data representing a boundary between continuous sections during each of which a chord is continued, where the boundary estimation model outputs boundary data in response to an input of a time series of first feature amounts of the audio signal; and extract a second feature amount from the time series of the first feature amounts of the audio signal for each of the continuous sections represented by the boundary data output by the boundary estimation model, and wherein the processor is configured to, in estimating the second chord, estimate a second chord by inputting the first chord and the second feature amount to the trained model.
