Another key defining characteristic of idiodexterity is that it involves adopting a handedness approach that fundamentally alters the relationship of our body with the instrument. The crucial thing about string instruments is that (with the exception of single-stringed instruments) the pitch is organised in two dimensions.
When we decide to hold the instrument ‘the other way around’, we invert the order of the strings in relation to our body. This changes how one of the two dimensions of pitch is organised from our perspective: the sense of up and down is still preserved along the length of the instrument’s fingerboard if it has one, but the sense of up and down as our fingers move across the strings is inverted.
