We propose a novel method of automatic music transcription for piano music which converts acoustic data into some musical notations. In the method, the relationship between acoustic and performance data is modeled using Shared Gaussian Process Latent Variable Model (SGPLVM) through assuming both data are generated from a common latent variable. Although many approaches have been studied, any methods have not achieved a sufficient performance and further improvement is demanded. We attempt to improve it by utilizing SGPLVM. We show that our method outperforms existing methods in the frame level evaluation with the MAPS database (F-measure: 0.78).
