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 13):
The chord estimation apparatus according to  claim 8 , wherein the processor is further configured to:\n execute a chord transition model that has learned relationships between time series of feature amounts and time series of pieces of chord data, each piece of chord data representing a chord, where the chord transition model outputs a time series of pieces of chord data in response to an input of a time series of a feature amounts of the audio signal, and wherein the processor is configured to, in estimating the second chord, estimate a second chord based on an output from the trained model and the output time series of pieces of chord data.
