How can a musician effectively transition between legato and staccato playing techniques in a musical performance?

To transition between legato and staccato playing techniques in a musical performance, a musician can adjust their bowing or finger pressure on the instrument. For legato playing, they should use smooth and connected bow strokes or finger movements, while for staccato playing, they should use short and detached bow strokes or finger movements. Practicing these techniques separately and gradually combining them can help achieve a seamless transition between legato and staccato playing.
