Finish what you Start....
Every phrase, indeed every note, has to have a beautiful and thoughtful ending that is appropriate for the musical demand at the moment. Too many students chop last notes of phrases, often to take a breath for what lies ahead. Although a good intention, it will yield a poor result. I like to envision the shape of the last notes of phrases: some are square or like an exclamation point (emphatic), others more demure with the shape of a true taper(like a very tiny dimuendo). Other notes should be phrased as periods in sentences, some act as commas. Figure out the musical demand, and the technical skill required to make it happen. But never leave those phrases ragged at the ends! Attention to detail is crucial. Practice tapers of various lengths and shapes on scales. Try out different ways to end notes in phrases, listening to the musical meanings. Finish with polish!
