Recent piano teaching systems mainly rely on MIDI data. However, MIDI data contains only little information about the student‘s movement. Therefore, additional data channels can potentially be valuable for future piano teaching systems. In this paper we have examined the question, if inertial measurement sensors attached to the piano student‘s arm can provide information that could be relevant for a piano teaching system. Therefore, we have attached a prototypical sensor that provides accelerometer and gyroscope data to the arm of a pianist. The pianist performed different piano playing patterns such as rotation of the forearm, tremoli, trills, scales, jumps, vertical forearm motion, repetition, octave repetition and connection of loud and soft notes. We show that these playing patterns can be distinguished based on the data from our sensor. Using this technique, a piano teaching system could also be able to assess the piano student‘s arm motions. 1.
