I paraphrase a nugget of wisdom I heard in a master class I observed led by the flutist, Emmanuel Pahud, this morning, but it went something like this:
"...This is precision work...it is important to do this, because when we don't pay attention to these details, we begin to do things out of habit...and all habits are bad habits. Music is meant to be expressive. When we do something out of habit, it has no expression."
Amen, amen, amen.
