Here are some videos explaining the basics of what is meant by an idiodextrous approach to the double bass and discussing the physical and sonic consequences.

VIDEO 1a: Not a Mirror Image
This video explains why playing ‘back-to-front’ is not a mirror image of playing ‘right-handed’ – that would be playing ‘left-handed‘ on a ‘left-handed’ instrument. The most important thing to notice is that in an idiodextrous approach, the order of the strings in relation to the bassist’s body is reversed.
VIDEO 2: External Asymmetry
This video demonstrates the asymmetries of the double bass on the outside.
VIDEO 3: Internal Asymmetry
This video explains the asymmetries of the internal construction features of the double bass.
VIDEO 4: Physical Challenges
This video explains the unique physical consequences of playing idiodextrously. Most of the challenges are because of the reversed string order explained in Videos 1a and 2.
VIDEO 5: Sound Production
This video explains why ididextrous bassists can have a harder time producing a full, deep sound than ‘regular’ bassists. It has a lot to do with the internal asymmetries of the bass (the sound post and bass bar) described in Video 3.
