The purpose of this paper is to clarify the differences in the basic conducting manner between trained conductors and beginners using a digital motion analysis device.

  Through the statistic examination of the 'time-lag' between metronome sounds and beat-points of each subject's conducting motion, the following results were obtained ;

1. While beat-points of beginners tend to coincide with metronome sounds, those of trained conductors are rather earlier than metronome sounds.

2. Beginners' downward motion-speed is higher than their upward one. Contrarily, trained conductors' upward motion-speed is higher than their downward one.

3. Beginners' conducting manner is unstable and tends to show waste movements.
