To practise this bowing separate the variables and work on one at a time.
Practise the bowing on an open string. Make sure the bow hold is comfortable when supporting the bow in the air.
Notice the 'active elbow' movement of the upper arm where the elbow drops on the up-bow and raises on the down-bow. This movement gives impetus to the lift off the string and allows for a gentle landing back on the string. When playing the tune this upper-arm movement is modified to accommodate the vertical string-crossing movement.
As with all bowing styles with a strong character make the gigue bowing style subservient to the musical line.
This excerpt is from "Allegro assai", the 3rd movement of Bachs Concerto in A Minor.
