"Broad playing gives the singing tone--the true violin tone--a long bow
drawn its full length. Like every general rule though, this one must be
modified by the judgment of the individual player. Violin playing is an
art of many mysteries. Some pupils grasp a point at once; others have to
have it explained seven or eight different ways before grasping it. The
serious student should practice not less than four hours, preferably in
twenty minute intervals. After some twenty minutes the brain is apt to
tire. And since the fingers are controlled by the brain, it is best to
relax for a short time before going on. Mental and physical control must
always go hand in hand. Four hours of intelligent, consistent practice
work are far better than eight or ten of fatigued effort.
