Playing through the “skeleton” of a tremolo piece helps reduce it in your mind’s ear to the essentials of what is happening on the musical front. Because we spend so much time developing the fluidity, clarity, speed, and all that goes into a beautiful tremolo technique, often our attention is so myopically focused on the minutiae of technique that we ignore the larger question of what a tremolo piece is trying to achieve musically.
There are various ways to mentally condense the way you perceive your pieces to make them seem less daunting. The most tried and true method is to play through them well hundreds of times. But because it takes time to develop the endurance and speed to perform a tremolo piece at tempo comfortably, play through them instead in an abbreviated way, as illustrated below, at faster tempos:
Another method, which I have grown to like despite the substandard sonic quality, was recommended by guitarist Philip Hii in his insightful book, Art of Virtuosity. In this method, shown below, ami act as one and pluck at the same time. Think of plucking a chord, but on one string. It won’t sound pretty, but in addition to focusing your attention on the bigger picture, by putting all of your fingers down at once you discover what position will give you access to all the strings in the most efficient way.
