I like to solve while listening to music what type depends on the event for most events I'll just listen to my normal music
but for BLD I'll listen to instrumental music if I even listen to music
A lot of people think it's a slightly bigger violin, but it has a mellower sound like the upper range of a cello or tenor in singing. Sadly, as a viola player a long time ago, the mid range is underutilized in composed music. Telemann at least did a whole viola concerto.
