1. A performance analysis method realized by a computer, the performance analysis method comprising:
acquiring a time series of input data that are pitch data representing pitches and that are generated from performance data which are musical instrument digital interface data representing a performance by a user on an electronic instrument; and
inputting the time series of input data into an estimation model, thereby generating a time series of output data for controlling an acoustic effect to be added to sound having the pitches,
the estimation model being a model
that is trained by the computer, or trained and transferred from an estimation model construction device, and
that has learned a relationship between a plurality of items of training input data representing training pitches and a plurality of items of training output data representing a training acoustic effect to be added to training sound having the training pitches.
