Anticipatory and sequential motor control in piano playing

Area of Science:

• Cognitive Science
• Neuroscience
• Music Performance

Background:

• Sequential movement organization is crucial in skilled motor tasks.
• Previous research suggested serial organization in typing.
• The potential for anticipatory adjustments in piano playing remained unclear.

Purpose of the Study:

• To investigate anticipatory modifications in pianists' hand and finger kinematics.
• To determine if kinematic divergence occurs before the final common note in musical phrases.
• To compare movement organization in piano playing with that of typing.

Main Methods:

• Pianists played musical excerpts on an electronic keyboard with recorded MIDI data.
• Optoelectronic motion capture recorded right wrist and finger movements.
• Analysis focused on kinematic divergence timing relative to common notes.

Main Results:

• Piano playing can involve anticipatory modifications of hand and finger kinematics.
• The timing of kinematic divergence varied significantly across musical pieces.
• Anticipatory adjustments, up to 500 ms before a note, were observed, particularly with maneuvers like 'thumb-under'.
• Some pieces showed strict serial ordering, while others displayed intermediate patterns.

Conclusions:

• Anticipatory kinematic adjustments occur in piano playing, similar to coarticulation in speech.
• Movement sequence organization is flexible, adapting to task demands.
• A preference for strict serial execution exists when compatible with musical requirements.
