Hi everybody--a few questions from a 'newbe' to the bow. Your expertise most welcome. a) Do cello / violinists / double bass players use the same bowing technique? b) I notice that cello players seem to use left hand vibrato more than double bass players--is that so? c) If you were playing a slow piece of music--say 50bpm--would you tend to use more vibrato than say 100bpm? d ) When playing in an orchestra how often do you look at the conductor? How do you manage this by taking your eyes off the music and not getting lost? Try to look at both at the same time? Know the piece before-hand?
