With a mind so alien from the human experience, lizardfolk experience a limited range of emotions. Therefore, they have no understanding or appreciation for finer arts such as music.
This lizardfolk, however, learned that by mimicking patterns and noises that humanlike races play on these instruments, they can sometimes attain great wealth and many pleasures. (If they play the right notes in the right sequence)
Thus began the journey of our lizardfolk bard.
