I've found some mix of cello or contrabass, or with a duduk flute as in this case, works best when I study. If I hear voices or uplifting, spirited music my concentration is thrown off. I mostly do this if copying a manuscript.
Today I'm doing Vol. 4 of the Agni Purana, chapter 247 The characteristics of a building site
. Then I'll likely track down some random Chinese myth that catches my eye and copy it too, or at least take notes. This kind of music is perfect for deep somatic digestion of a text.
