Hans Jørgen Jensen is an affable cello teacher from whose studio have come cello players who win in international cello competitions and garner spots in top orchestras around the world. He’s a wonderful teacher and an interesting, busy man. There were many gems to admire when he spoke with me about practice, but the one that sticks in my mind, the one that was powerful enough to make it a chapter in The Practice of Practice was the power of goals. Another chapter covers what I’ve called Guerrilla Practice: snatching a tiny fragment of practice when you can, either once a day or, ideally, throughout the day. Both are covered briefly below.
