Sight-reading of violinists: eye movements anticipate the musical flow

Wurtz, Pascal ; Mueri, René M. ; Wiesendanger, Mario

In: Experimental Brain Research, 2009, vol. 194, no. 3, p. 445-450

When sight-reading a piece of music the eyes constantly scan the score slightly ahead of music execution. This separation between reading and acting is commonly termed eye-hand span and can be expressed in two ways: as anticipation in notes or in time. Previous research, predominantly in piano players, found skill-dependent differences of eye-hand span. To date no study has explored visual...

Coordination of bowing and fingering in violin playing

Baader, Andreas P. ; Kazennikov, Oleg ; Wiesendanger, Mario

In: Cognitive Brain Research, 2005, vol. 23(2-3), p. 436

Playing string instruments implies motor skills including asymmetrical interlimb coordination. How special is musical skill as compared to other bimanually coordinated, non-musical skillful performances? We succeeded for the first time to measure quantitatively bimanual coordination in violinists playing repeatedly a simple tone sequence. A motion analysis system was used to record finger and bow...
