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 5):
The chord estimation method according to  claim 1 , further comprising:\n estimating boundary data representative of a boundary between continuous sections during each of which a chord is continued, by inputting a time series of first feature amounts of the audio signal to a boundary estimation model that has learned relationships between a time series of first feature amounts and pieces of the boundary data; and extracting a second feature amount from the time series of the first feature amounts of the audio signal for each of continuous sections represented by the estimated boundary data, wherein estimating the second chord includes estimating a second chord by inputting the first chord and the second feature amount to the trained model.
