The T-RHYTHM system, that supports individual learners in playing or singing in solo or ensemble situations, is proposed. T-RHYTHM provides each learner with the rhythm of music through her tactile sense, and supports her so that she can recognize her own rhythm without being confused by other learners' performances or singing voices. The rhythm of the music given to each learner is determined based on a performance by an accompanist and transmitted to her vibration device via a wireless communication. The user studies of T-RHYTHM were conducted in solo and ensemble settings, and proved that the system could effectively improve learners? rhythm recognition skills.
