I would say a conductor, but a conductor only leads orchestra's or choirs.
It will have a totally different sound quality than using major chords because minor chords are the notes you really have to pay attention to or it’s easy to mess them up or get mixed up. Hope that helped youxx
Dante Gabriel Rossetti was an English painter from the 1800's.
The Proserpine is an Oil on Canvas from 1874 and it is said to reflect the artist's personal life and state of mind: he most likely suffered from depression (that is why the expression is sad). He had a nervous breakdown just a few years before creating this painting.
